Rev. 03 — 10 July 2007
Product data sheet
1. General description
The P89LPC9102/9103/9107 are single-chip microcontrollers in low-cost 10-pin and
14-pin packages based on a high performance processor architecture that executes
instructions in two to four clocks, six times the rate of standard 80C51 devices. Many
system-level functions have been incorporated into the P89LPC9102/9103/9107 in order
to reduce component count, board space, and system cost.
2. Features
2.1 Principal features
n 1 kB byte-erasable flash code memory organized into 256-byte sectors and 16-byte
pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage.
n 128-byte RAM data memory.
n Two 16-bit timer/counters (P89LPC9102/9107). Two 16-bit timers (P89LPC9103)
n 23-bit system timer that can also be used as a RTC.
n Four input multiplexed 8-bit A/D converter/single DAC output. One analog comparator
with selectable reference.
n Enhanced UART with fractional baud rate generator, break detect, framing error
detection, automatic address detection and versatile interrupt capabilities
(P89LPC9103/9107).
n High-accuracy internal RC oscillator option, factory calibrated to 1 %, allows operation
without external oscillator components. The RC oscillator option is selectable and fine
tunable.
n VDD operating range of 2.4 V to 3.6 V with 5 V tolerant I/O pins (may be pulled up or
driven to 5.5 V).
n Up to 10 (P89LPC9107) or eight (P89LPC9102/9103) I/O pins when using internal
oscillator and reset options.
n Ultra-small 10-pin HVSON package (P89LPC9102/9103). 14-pin TSSOP and DIP
packages (P89LPC9107).
2.2 Additional features
n A high performance 80C51 CPU provides instruction cycle times of 136 ns to 272 ns
for all instructions except multiply and divide when using the internal 7.3728 MHz RC
oscillator in clock doubling mode (111 ns to 222 ns when using an external 18 MHz
clock). A lower clock frequency for the same performance results in power savings and
reduced EMI.

8-bit microcontrollers with two-clock accelerated 80C51 core
n In-Application Programming (IAP-Lite) and byte erase allows code memory to be used
for non-volatile data storage.
n Serial flash ICP allows simple production coding with commercial EPROM
programmers. Flash security bits prevent reading of sensitive application programs.
n Watchdog timer with separate on-chip oscillator, requiring no external components.
The watchdog prescaler is selectable from eight values.
n Low voltage reset (Brownout detect) allows a graceful system shutdown when power
fails. May optionally be configured as an interrupt.
n Idle mode and two different reduced power Power-down modes. Improved wake-up
from Power-down mode (a LOW interrupt input starts execution). Typical Power-down
mode current is less than 1 µA (total Power-down mode with voltage comparators
disabled).
n Active-LOW reset. On-chip power-on reset allows operation without external reset
components. A reset counter and reset glitch suppression circuitry prevent spurious
and incomplete resets. A software reset function is also available.
n Programmable port output configuration options: quasi-bidirectional, open drain,
push-pull, input-only.
n Port ‘input pattern match’ detect. Port 0 may generate an interrupt when the value of
the pins match or do not match a programmable pattern.
n LED drive capability (20 mA) on all port pins. A maximum limit is specified for the
entire chip.
n Controlled slew rate port outputs to reduce EMI. Outputs have approximately 10 ns
minimum ramp times.
n Only power and ground connections are required to operate the
P89LPC9102/9103/9107 when internal reset option is selected.
n Four interrupt priority levels.
n Two keypad interrupt inputs.
n Second data pointer.
n External clock input.
n Clock output (P89LPC9102/9107).
n Schmitt trigger port inputs.
n Emulation support.

RST — External Reset input during power-on or if selected via User Configuration
Register 1 (UCFG1). When functioning as a reset input a LOW on this pin resets the
microcontroller, causing I/O ports and peripherals to take on their default states, and
the processor begins execution at address 0. When using an oscillator frequency
above 12 MHz, the reset input function of P1.5 must be enabled. An external
circuit is required to hold the device in reset at power-up until VDD has reached
its specified level. When system power is removed VDD will fall below the
minimum specified operating voltage. When using an oscillator frequency
above 12 MHz, in some applications, an external brownout detect circuit may
be required to hold the device in reset when VDD falls below the minimum
specified operating voltage.

Type
Description
I/O
Port 1: Port 1 is an I/O port with a user-configurable output type. During reset Port 1
latches are configured in the input-only mode with the internal pull-up disabled. The
operation of the configurable Port 1 pins as inputs and outputs depends upon the port
configuration selected. Each of the configurable port pins are programmed
independently. Refer to Section 8.12.1 “Port configurations” and Table 12 “Static
characteristics” for details. P1.5 is input-only.
All pins have Schmitt triggered inputs.
Port 1 also provides various special functions as described below:
P1.0/TXD
6
P1.1/RXD
9
P1.2/T0

P1.5/RST

I/O
P1.0 — Port 1 bit 0.
O
TXD — Serial port transmitter data.
I/O
P1.1 — Port 1 bit 1.
I
RXD — Serial port receiver data.
I/O
P1.2 — Port 1 bit 2.
I/O
T0 — Timer/counter 0 external count input or overflow/PWM output.
I
P1.5 — Port 1 bit 5 (input-only).
I
RST — External Reset input during Power-on or if selected via UCFG1. When
functioning as a reset input a LOW on this pin resets the microcontroller, causing I/O
ports and peripherals to take on their default states, and the processor begins
execution at address 0. When using an oscillator frequency above 12 MHz, the
reset input function of P1.5 must be enabled. An external circuit is required to
hold the device in reset at power-up until VDD has reached its specified level.
When system power is removed VDD will fall below the minimum specified
operating voltage. When using an oscillator frequency above 12 MHz, in some
applications, an external brownout detect circuit may be required to hold the
device in reset when VDD falls below the minimum specified operating voltage.

Power supply: This is the power supply voltage for normal operation as well as Idle
mode and Power-down mode.

8. Functional description
Remark: Please refer to the P89LPC9102/9103/9107 User manual UM10112 for a more
detailed functional description.
8.1 Special function registers
Remark: Special Function Registers (SFRs) accesses are restricted in the following
ways:
• User must not attempt to access any SFR locations not defined.
• Accesses to any defined SFR locations must be strictly for the functions for the SFRs.
• SFR bits labeled ‘-’, ‘0’ or ‘1’ can only be written and read as follows:
– ‘-’ Unless otherwise specified, must be written with ‘0’, but can return any value
when read (even if it was written with ‘0’). It is a reserved bit and may be used in
future derivatives.
– ‘0’ must be written with ‘0’, and will return a ‘0’ when read.
– ‘1’ must be written with ‘1’, and will return a ‘1’ when read.

[1]
Unimplemented bits in SFRs (labeled ’-’) are X (unknown) at all times. Unless otherwise specified, ones should not be written to these bits since they may be used for other
purposes in future derivatives. The reset values shown for these bits are logic 0s although they are unknown when read.
[2]
All ports are in input-only (high-impedance) state after power-up.
[3]
The RSTSRC register reflects the cause of the P89LPC9102/9103/9107 reset. Upon a power-up reset, all reset source flags are cleared except POF and BOF; the power-on reset
value is xx11 0000.
[4]
The only reset source that affects these SFRs is power-on reset.
[5]
On power-on reset, the TRIM SFR is initialized with a factory preprogrammed value. Other resets will not cause initialization of the TRIM register.
[6]
After reset, the value is 1110 01x1, i.e., PRE2 to PRE0 are all logic 1s, WDRUN = 1 and WDCLK = 1. WDTOF bit is logic 1 after watchdog timer reset and is logic 0 after power-on
reset. Other resets will not affect WDTOF.

Unimplemented bits in SFRs (labeled ’-’) are X (unknown) at all times. Unless otherwise specified, ones should not be written to these bits since they may be used for other
purposes in future derivatives. The reset values shown for these bits are logic 0s although they are unknown when read.
[2]
BRGR1 and BRGR0 must only be written if BRGEN in BRGCON SFR is logic 0. If any are written while BRGEN = 1, the result is unpredictable.

All ports are in input-only (high-impedance) state after power-up.
[4]
The RSTSRC register reflects the cause of the P89LPC9102/9103/9107 reset. Upon a power-up reset, all reset source flags are cleared except POF and BOF; the power-on reset
value is xx11 0000.
[5]
The only reset source that affects these SFRs is power-on reset.
[6]
On power-on reset, the TRIM SFR is initialized with a factory preprogrammed value. Other resets will not cause initialization of the TRIM register.
[7]
After reset, the value is 1110 01x1, i.e., PRE2 to PRE0 are all logic 1s, WDRUN = 1 and WDCLK = 1. WDTOF bit is logic 1 after watchdog timer reset and is logic 0 after power-on
reset. Other resets will not affect WDTOF.

NXP Semiconductors
8-bit microcontrollers with two-clock accelerated 80C51 core
8.2 Enhanced CPU
The P89LPC9102/9103/9107 uses an enhanced 80C51 CPU which runs at six times the
speed of standard 80C51 devices. A machine cycle consists of two CPU clock cycles, and
most instructions execute in one or two machine cycles.
8.3 Clocks
8.3.1 Clock definitions
The P89LPC9102/9103/9107 device has internal clocks as defined below:
OSCCLK — Input to the DIVM clock divider. OSCCLK is selected from one of the clock
sources (see Figure 11 “Block diagram of P89LPC9102 oscillator control”) and can also
be optionally divided to a slower frequency (see Section 8.8 “CCLK modification: DIVM
register”).
Note: fosc is defined as the OSCCLK frequency.
CCLK — CPU clock; output of the clock divider. There are two CCLK cycles per machine
cycle, and most instructions are executed in one to two machine cycles (two or four CCLK
cycles).
RCCLK — The internal 7.373 MHz RC oscillator output. The clock doubler option, when
enabled, provides an output frequency of 14.746 MHz.
PCLK — Clock for the various peripheral devices and is CCLK⁄2.
8.3.2 CPU clock (CCLK)
The P89LPC9102/9103/9107 provides user-selectable oscillator options in generating the
CPU clock. This allows optimization for a range of needs from high precision to lowest
possible cost. These options are configured when the flash memory is programmed and
include an on-chip watchdog oscillator, an on-chip RC oscillator, and an external clock
input.
8.4 On-chip RC oscillator option
The P89LPC9102/9103/9107 has a 6-bit TRIM register that can be used to tune the
frequency of the RC oscillator. During reset, the TRIM value is initialized to a factory
pre-programmed value to adjust the oscillator frequency to 7.373 MHz ± 1 % at room
temperature. End-user applications can write to the Trim register to adjust the on-chip RC
oscillator to other frequencies. When the clock doubler option is enabled (UCFG1.3 = 1)
the output frequency is 14.746 MHz. If CCLK is 8 MHz or slower, the CLKLP SFR bit
(AUXR1.7) can be set to logic 1 to reduce power consumption. On reset, CLKLP is logic 0
allowing highest performance access. This bit can then be set in software if CCLK is
running at 8 MHz or slower.
The RCCLK bit (TRIM.7) can be used to switch between the clock source selected by
UCFG1 and the internal RC oscillator. This allows a low frequency source such as the
WDT or low speed external source to clock the device in order to save power and then
switch to the higher speed internal RC oscillator to perform processing.

8.6 External clock input option
In this configuration, the processor clock is derived from an external source driving the
P0.5/CMPREF/CLKIN pin. The rate may be from 0 Hz up to 18 MHz. The
P0.5/CMPREF/CLKIN pin may also be used as a standard port pin. When using an
oscillator frequency above 12 MHz, the reset input function of P1.5 must be
enabled. An external circuit is required to hold the device in reset at power-up until
VDD has reached its specified level. When system power is removed VDD will fall
below the minimum specified operating voltage. When using an oscillator

8-bit microcontrollers with two-clock accelerated 80C51 core
frequency above 12 MHz, in some applications, an external brownout detect circuit
may be required to hold the device in reset when VDD falls below the minimum
specified operating voltage.
8.7 CCLK wake-up delay
The P89LPC9102/9103/9107 has an internal wake-up timer that delays the clock until it
stabilizes depending to the clock source used.
8.8 CCLK modification: DIVM register
The OSCCLK frequency can be divided down up to 510 times by configuring a dividing
register, DIVM, to generate CCLK. This feature makes it possible to temporarily run the
CPU at a lower rate, reducing power consumption. By dividing the clock, the CPU can
retain the ability to respond to events that would not exit Idle mode by executing its normal
program at a lower rate. This can also allow bypassing the oscillator start-up time in cases
where Power-down mode would otherwise be used. The value of DIVM may be changed
by the program at any time without interrupting code execution.
8.9 Low power select
If CCLK is 8 MHz or slower, the CLKLP SFR bit (AUXR1.7) can be set to logic 1 to lower
the power consumption further. On any reset, CLKLP is logic 0.
8.10 Memory organization
The various P89LPC9102/9103/9107 memory spaces are as follows:
• DATA
128 bytes of internal data memory space (00H:7FH) accessed via direct or indirect
addressing, using instruction other than MOVX and MOVC. All or part of the stack
may be in this area.
• SFR
Special Function Registers. Selected CPU registers and peripheral control and status
registers, accessible only via direct addressing.
• CODE
1 kB of Code memory space, accessed as part of program execution and via the
MOVC instruction.
8.11 Interrupts
The P89LPC9102 supports nine interrupt sources: timers 0 and 1, brownout detect,
watchdog timer/RTC, keyboard, comparator 1, and the A/D converter.
The P89LPC9103/9107 support nine interrupt sources: timers 0 and 1, serial port Tx,
serial port Rx, combined serial port Rx/Tx, brownout detect, watchdog timer/RTC,
keyboard, comparator, and the A/D converter.
Each interrupt source can be individually enabled or disabled by setting or clearing a bit in
the interrupt enable registers IEN0 or IEN1. The IEN0 register also contains a global
disable bit, EA, which disables all interrupts.

NXP Semiconductors
8-bit microcontrollers with two-clock accelerated 80C51 core
Each interrupt source can be individually programmed to one of four priority levels by
setting or clearing bits in the interrupt priority registers IP0, IP0H, IP1, and IP1H. An
interrupt service routine in progress can be interrupted by a higher priority interrupt, but
not by another interrupt of the same or lower priority. The highest priority interrupt service
cannot be interrupted by any other interrupt source. If two requests of different priority
levels are pending at the start of an instruction, the request of higher priority level is
serviced.
If requests of the same priority level are pending at the start of an instruction, an internal
polling sequence determines which request is serviced. This is called the arbitration
ranking. Note that the arbitration ranking is only used to resolve pending requests of the
same priority level.
8.11.1 External interrupt inputs
The P89LPC9102/9103/9107 has a Keypad Interrupt function. This can be used as an
external interrupt input.
If enabled when the P89LPC9102/9103/9107 is put into Power-down mode or Idle mode,
the interrupt will cause the processor to wake-up and resume operation. Refer to Section
8.14 “Power reduction modes” for details.

8.12.1 Port configurations
All but one I/O port pin on the P89LPC9102/9103/9107 may be configured by software to
one of four types on a bit-by-bit basis. These are: quasi-bidirectional (standard 80C51 port
outputs), push-pull, open drain, and input-only. Two configuration registers for each port
select the output type for each port pin.
P1.5 (RST) can only be an input and cannot be configured.

NXP Semiconductors
8-bit microcontrollers with two-clock accelerated 80C51 core
8.12.2 Quasi-bidirectional output configuration
Quasi-bidirectional output type can be used as both an input and output without the need
to reconfigure the port. This is possible because when the port outputs a logic HIGH, it is
weakly driven, allowing an external device to pull the pin LOW. When the pin is driven
LOW, it is driven strongly and able to sink a fairly large current. These features are
somewhat similar to an open-drain output except that there are three pull-up transistors in
the quasi-bidirectional output that serve different purposes.
The P89LPC9102/9103/9107 is a 3 V device, however, the pins are 5 V-tolerant. In
quasi-bidirectional mode, if a user applies 5 V on the pin, there will be a current flowing
from the pin to VDD, causing extra power consumption. Therefore, applying 5 V in
quasi-bidirectional mode is discouraged.
A quasi-bidirectional port pin has a Schmitt triggered input that also has a glitch
suppression circuit.
8.12.3 Open-drain output configuration
The open-drain output configuration turns off all pull-ups and only drives the pull-down
transistor of the port driver when the port latch contains a logic 0. To be used as a logic
output, a port configured in this manner must have an external pull-up, typically a resistor
tied to VDD.
An open-drain port pin has a Schmitt triggered input that also has a glitch suppression
circuit.
8.12.4 Input-only configuration
The input-only port configuration has no output drivers. It is a Schmitt triggered input that
also has a glitch suppression circuit.
8.12.5 Push-pull output configuration
The push-pull output configuration has the same pull-down structure as both the
open-drain and the quasi-bidirectional output modes, but provides a continuous strong
pull-up when the port latch contains a logic 1. The push-pull mode may be used when
more source current is needed from a port output. A push-pull port pin has a Schmitt
triggered input that also has a glitch suppression circuit.
8.12.6 Port 0 analog functions
The P89LPC9102/9103/9107 incorporates an Analog Comparator. In order to give the
best analog function performance and to minimize power consumption, pins that are being
used for analog functions must have the digital outputs and digital inputs disabled.
Digital outputs are disabled by putting the port output into the Input-only (high-impedance)
mode as described in Section 8.12.4 “Input-only configuration”.
Digital inputs on Port 0 may be disabled through the use of the PT0AD register. On any
reset, the PT0AD bits default to logic 0s to enable digital functions.
8.12.7 Additional port features
After power-up, all pins are in Input-only mode. Please note that this is different from
the LPC76x series of devices.

NXP Semiconductors
8-bit microcontrollers with two-clock accelerated 80C51 core
• After power-up all I/O pins, except P1.5, may be configured by software.
• Pin P1.5 is input-only.
Every output on the P89LPC9102/9103/9107 has been designed to sink typical LED drive
current. However, there is a maximum total output current for all ports which must not be
exceeded. Please refer to Table 12 “Static characteristics” for detailed specifications.
All ports pins that can function as an output have slew rate controlled outputs to limit noise
generated by quickly switching output signals. The slew rate is factory-set to
approximately 10 ns rise and fall times.
8.13 Power monitoring functions
The P89LPC9102/9103/9107 incorporates power monitoring functions designed to
prevent incorrect operation during initial power-up and power loss or reduction during
operation. This is accomplished with two hardware functions: Power-on Detect and
Brownout detect.
8.13.1 Brownout detection
The Brownout detect function determines if the power supply voltage drops below a
certain level. The default operation is for a Brownout detection to cause a processor reset,
however, it may alternatively be configured to generate an interrupt.
Brownout detection may be enabled or disabled in software.
If Brownout detection is enabled, the brownout condition occurs when VDD falls below the
brownout trip voltage, Vbo (see Table 12 “Static characteristics”), and is negated when VDD
rises above Vbo. If the P89LPC9102/9103/9107 device is to operate with a power supply
that can be below 2.7 V, Brownout detect Enable (BOE) should be left in the
unprogrammed state so that the device can operate at 2.4 V, otherwise continuous
brownout reset may prevent the device from operating.
For correct activation of Brownout detect, the VDD rise and fall times must be observed.
Please see Table 12 “Static characteristics” for specifications.
8.13.2 Power-on detection
The Power-on Detect has a function similar to the Brownout detect, but is designed to
work as power comes up initially, before the power supply voltage reaches a level where
Brownout detect can work. The Power-on detect flag (POF) in the RSTSRC register is set
to indicate an initial power-up condition. The POF flag will remain set until cleared by
software.
8.14 Power reduction modes
The P89LPC9102/9103/9107 supports three different power reduction modes. These
modes are Idle mode, Power-down mode, and Total Power-down mode.
8.14.1 Idle mode
Idle mode leaves peripherals running in order to allow them to activate the processor
when an interrupt is generated. Any enabled interrupt source or reset may terminate Idle
mode.

NXP Semiconductors
8-bit microcontrollers with two-clock accelerated 80C51 core
8.14.2 Slow-down mode using the DIVM register
Slow-down mode is achieved by dividing down the OSCCLK frequency to generate CCLK.
This division is accomplished by configuring the DIVM register to divide OSCCLK by up to
510 times. This feature makes it possible to temporarily run the CPU at a lower rate,
reducing power consumption. By dividing the clock, the CPU can retain the ability to
respond to events that would not exit Idle mode by executing its normal program at a lower
rate. This can also allow bypassing the oscillator start-up time in cases where
Power-down mode would otherwise be used. The value of DIVM may be changed by the
program at any time without interrupting code execution.
8.14.3 Power-down mode
The Power-down mode stops the oscillator in order to minimize power consumption. The
P89LPC9102/9103/9107 exits Power-down mode via any reset, or certain interrupts. In
Power-down mode, the power supply voltage may be reduced to the data retention
voltage VDDR. This retains the RAM contents at the point where Power-down mode was
entered. SFR contents are not guaranteed after VDD has been lowered to VDDR, therefore
it is highly recommended to wake-up the processor via reset in this case. VDD must be
raised to within the operating range before the Power-down mode is exited.
Some chip functions continue to operate and draw power during Power-down mode,
increasing the total power used during Power-down mode. These include: Brownout
detect, watchdog timer, comparators (note that comparator can be powered-down
separately), and RTC/system timer. The internal RC oscillator is disabled unless both the
RC oscillator has been selected as the system clock and the RTC is enabled.
8.14.4 Total Power-down mode
This is the same as Power-down mode except that the brownout detection circuitry and
the voltage comparators are also disabled to conserve additional power. The internal RC
oscillator is disabled unless both the RC oscillator has been selected as the system clock
and the RTC is enabled. If the internal RC oscillator is used to clock the RTC during
Power-down mode, there will be high power consumption. Please use an external low
frequency clock to achieve low power with the RTC running during Power-down mode.
8.15 Reset
The P1.5/RST pin can function as either an active-LOW reset input or as a digital input,
P1.5. The RPE (Reset Pin Enable) bit in UCFG1, when set to logic 1, enables the external
reset input function on P1.5. When cleared, P1.5 may be used as an input pin.
Remark: During a power-up sequence, the RPE selection is overridden and this pin will
always function as a reset input. An external circuit connected to this pin should not
hold this pin LOW during a power-on sequence as this will keep the device in reset.
After power-up this input will function either as an external reset input or as a digital input
as defined by the RPE bit. Only a power-up reset will temporarily override the selection
defined by RPE bit. Other sources of reset will not override the RPE bit.
Remark: During a power cycle, VDD must fall below VPOR (see Table 12 “Static
characteristics”) before power is reapplied, in order to ensure a power-on reset.
Reset can be triggered from the following sources:
• External reset pin (during power-up or if user configured via UCFG1)

For every reset source, there is a flag in the Reset Register, RSTSRC. The user can read
this register to determine the most recent reset source. These flag bits can be cleared in
software by writing a logic 0 to the corresponding bit. More than one flag bit may be set:
• During a power-on reset, both POF and BOF are set but the other flag bits are
cleared.
• For any other reset, previously set flag bits that have not been cleared will remain set.
8.16 Timers 0 and 1
The P89LPC9102 has two general purpose timer/counters which are similar to the
standard 80C51 Timer 0 and Timer 1. These timers have five operating modes (modes 0,
1, 2, 3, and 6). Modes 0, 1, and 2 are the same for both Timers. Mode 3 is different.
The P89LPC9103/9107 has two general purpose timers which are similar to the standard
80C51 Timer 0 and Timer 1. These timers have four operating modes (modes 0, 1, 2, and
3). Modes 0, 1, and 2 are the same for both Timers. Mode 3 is different.
8.16.1 Mode 0
Putting either Timer into Mode 0 makes it look like an 8048 Timer, which is an 8-bit
Counter with a divide-by-32 prescaler. In this mode, the Timer register is configured as a
13-bit register. Mode 0 operation is the same for Timer 0 and Timer 1.
8.16.2 Mode 1
Mode 1 is the same as Mode 0, except that all 16 bits of the timer register are used.
8.16.3 Mode 2
Mode 2 configures the Timer register as an 8-bit counter with automatic reload. Mode 2
operation is the same for Timer 0 and Timer 1.
8.16.4 Mode 3
When Timer 1 is in Mode 3 it is stopped. Timer 0 in Mode 3 forms two separate 8-bit
counters and is provided for applications that require an extra 8-bit timer. When Timer 1 is
in Mode 3 it can still be used by the serial port as a baud rate generator.
8.16.5 Mode 6 (P89LPC9102/9107)
In this mode, the corresponding timer can be changed to a PWM with a full period of
256 timer clocks.

8.16.6 Timer overflow toggle output (P89LPC9102/9107)
Timers 0 and 1 can be configured to automatically toggle a port output whenever a timer
overflow occurs. The same device pins that are used for the T0 and T1 count inputs are
also used for the timer toggle outputs. The port outputs will be a logic 1 prior to the first
timer overflow when this mode is turned on.
8.17 RTC/system timer
The P89LPC9102/9103/9107 has a simple RTC that allows a user to continue running an
accurate timer while the rest of the device is powered-down. The RTC can be a wake-up
or an interrupt source. The RTC is a 23-bit down counter comprised of a 7-bit prescaler
and a 16-bit loadable down counter. When it reaches all logic 0s, the counter will be
reloaded again and the RTCF flag will be set. The clock source for this counter is the
CCLK. Only power-on reset will reset the RTC and its associated SFRs to the default
state.
8.18 UART (P89LPC9103/9107)
The P89LPC9103/9107 has an enhanced UART that is compatible with the conventional
80C51 UART except that Timer 2 overflow cannot be used as a baud rate source. The
P89LPC9103/9107 does include an independent Baud Rate Generator. The baud rate
can be selected from CCLK (divided by a constant), Timer 1 overflow, or the independent
Baud Rate Generator. In addition to the baud rate generation, enhancements over the
standard 80C51 UART include Framing Error detection, automatic address recognition,
selectable double buffering and several interrupt options. The UART can be operated in
four modes: shift register, 8-bit UART, 9-bit UART, and CCLK⁄32 or CCLK⁄16.
8.18.1 Mode 0
Serial data enters and exits through RXD. TXD outputs the shift clock. Eight bits are
transmitted or received, LSB first. The baud rate is fixed at 1⁄16 of the CPU clock
frequency.
8.18.2 Mode 1
10 bits are transmitted (through TXD) or received (through RXD): a start bit (logic 0),
8 data bits (LSB first), and a stop bit (logic 1). When data is received, the stop bit is stored
in RB8 in Special Function Register SCON. The baud rate is variable and is determined
by the Timer 1 overflow rate or the Baud Rate Generator (described in Section 8.18.5
“Baud rate generator and selection”).
8.18.3 Mode 2
11 bits are transmitted (through TXD) or received (through RXD): start bit (logic 0), 8 data
bits (LSB first), a programmable 9th data bit, and a stop bit (logic 1). When data is
transmitted, the 9th data bit (TB8 in SCON) can be assigned the value of logic 0 or logic 1.
Or, for example, the parity bit (P, in the PSW) could be moved into TB8. When data is
received, the 9th data bit goes into RB8 in Special Function Register SCON, while the stop
bit is not saved. The baud rate is programmable to either 1⁄16 or 1⁄32 of the CPU clock
frequency, as determined by the SMOD1 bit in PCON.

8.18.4 Mode 3
11 bits are transmitted (through TXD) or received (through RXD): a start bit (logic 0), 8
data bits (LSB first), a programmable 9th data bit, and a stop bit (logic 1). In fact, Mode 3 is
the same as Mode 2 in all respects except baud rate. The baud rate in Mode 3 is variable
and is determined by the Timer 1 overflow rate or the Baud Rate Generator (described in
section Section 8.18.5 “Baud rate generator and selection”).
8.18.5 Baud rate generator and selection
The P89LPC9103/9107 enhanced UART has an independent Baud Rate Generator. The
baud rate is determined by a baud-rate preprogrammed into the BRGR1 and BRGR0
SFRs which together form a 16-bit baud rate divisor value that works in a similar manner
as Timer 1. If the baud rate generator is used, Timer 1 can be used for other timing
functions.
The UART can use either Timer 1 or the baud rate generator output (see Figure 15). Note
that Timer T1 is further divided by 2 if the SMOD1 bit (PCON.7) is cleared. The
independent Baud Rate Generator uses CCLK.

8.18.6 Framing error
Framing error is reported in the status register (SSTAT). In addition, if SMOD0 (PCON.6)
is logic 1, framing errors can be made available in SCON.7, respectively. If SMOD0 is
logic 0, SCON.7 is SM0. It is recommended that SM0 and SM1 (SCON[7:6]) are set up
when SMOD0 is logic 0.
8.18.7 Break detect
Break detect is reported in the status register (SSTAT). A break is detected when
11 consecutive bits are sensed LOW. The break detect can be used to reset the device.
8.18.8 Double buffering
The UART has a transmit double buffer that allows buffering of the next character to be
written to SBUF while the first character is being transmitted. Double buffering allows
transmission of a string of characters with only one stop bit between any two characters,
as long as the next character is written between the start bit and the stop bit of the
previous character.
Double buffering can be disabled. If disabled (DBMOD, i.e., SSTAT.7 = 0), the UART is
compatible with the conventional 80C51 UART. If enabled, the UART allows writing to
SnBUF while the previous data is being shifted out. Double buffering is only allowed in
Modes 1, 2 and 3. When operated in Mode 0, double buffering must be disabled
(DBMOD = 0).

8.18.9 Transmit interrupts with double buffering enabled (Modes 1, 2 and 3)
Unlike the conventional UART, in double buffering mode, the Tx interrupt is generated
when the double buffer is ready to receive new data.
8.18.10 The 9th bit (bit 8) in double buffering (Modes 1, 2 and 3)
If double buffering is disabled TB8 can be written before or after SBUF is written, as long
as TB8 is updated some time before that bit is shifted out. TB8 must not be changed until
the bit is shifted out, as indicated by the Tx interrupt.
If double buffering is enabled, TB8 must be updated before SBUF is written, as TB8 will
be double-buffered together with SBUF data.
8.19 Analog comparators
One analog comparator is provided on the P89LPC9102/9103/9107. Comparator
operation is such that the output is a logic 1 (which may be read in a register) when the
positive input is greater than the negative input (selectable from a pin or an internal
reference voltage). Otherwise the output is a zero. The comparator may be configured to
cause an interrupt when the output value changes.
The connections to the comparator are shown in Figure 16. The comparator functions to
VDD = 2.4 V.
When the comparator is first enabled, the comparator’s interrupt flag is not guaranteed to
be stable for 10 microseconds. The comparator interrupt should not be enabled during
that time, and the comparator interrupt flag must be cleared before the interrupt is enabled
in order to prevent an immediate interrupt service.
When a comparator is disabled the comparator’s output, COx, goes HIGH. If the
comparator output was LOW and then is disabled, the resulting transition of the
comparator output from a LOW to HIGH state will set the comparator flag, CMFx. This will
cause an interrupt if the comparator interrupt is enabled. The user should therefore
disable the comparator interrupt prior to disabling the comparator. Additionally, the user
should clear the comparator flag, CMFx, after disabling the comparator.

An internal reference voltage generator may supply a default reference when a single
comparator input pin is used. The value of the internal reference voltage, referred to as
Vref(bg), is 1.23 V ± 3 %.

8.21 Comparator interrupt
The comparator has an interrupt flag contained in its configuration register. This flag is set
whenever the comparator output changes state. The flag may be polled by software or
may be used to generate an interrupt.
8.22 Comparator and power reduction modes
The comparator may remain enabled when Power-down mode or Idle mode is activated,
but the comparator is disabled automatically in Total Power-down mode.
If the comparator interrupt is enabled (except in Total Power-down mode), a change of the
comparator output state will generate an interrupt and wake-up the processor. If the
comparator output to a pin is enabled, the pin should be configured in the push-pull mode
in order to obtain fast switching times while in Power-down mode. The reason is that with
the oscillator stopped, the temporary strong pull-up that normally occurs during switching
on a quasi-bidirectional port pin does not take place.
The comparator consumes power in Power-down mode and Idle mode, as well as in the
normal operating mode. This fact should be taken into account when system power
consumption is an issue. To minimize power consumption, the user can disable the
comparator via PCONA.5 or put the device in Total Power-down mode.
8.23 Keypad interrupt (KBI)
The Keypad Interrupt function is intended primarily to allow a single interrupt to be
generated when Port 0 is equal to or not equal to a certain pattern. This function can be
used for bus address recognition or keypad recognition. The user can configure the port
via SFRs for different tasks.
The Keypad Interrupt Mask Register (KBMASK) is used to define which input pins
connected to Port 0 can trigger the interrupt. The Keypad Pattern Register (KBPATN) is
used to define a pattern that is compared to the value of Port 0. The Keypad Interrupt Flag
(KBIF) in the Keypad Interrupt Control Register (KBCON) is set when the condition is
matched while the Keypad Interrupt function is active. An interrupt will be generated if
enabled. The PATN_SEL bit in the Keypad Interrupt Control Register (KBCON) is used to
define equal or not-equal for the comparison.
In order to use the Keypad Interrupt as an original KBI function like in 87LPC76x series,
the user needs to set KBPATN = 0FFH and PATN_SEL = 1 (not equal), then any key
connected to Port 0 which is enabled by the KBMASK register will cause the hardware to
set KBIF and generate an interrupt if it has been enabled. The interrupt may be used to
wake-up the CPU from Idle mode or Power-down mode. This feature is particularly useful
in handheld, battery powered systems that need to carefully manage power consumption
yet also need to be convenient to use.
In order to set the flag and cause an interrupt, the pattern on Port 0 must be held longer
than six CCLKs.
8.24 Watchdog timer
The watchdog timer causes a system reset when it underflows as a result of a failure to
feed the timer prior to the timer reaching its terminal count. It consists of a programmable
12-bit prescaler, and an 8-bit down counter. The down counter is decremented by a tap

NXP Semiconductors
8-bit microcontrollers with two-clock accelerated 80C51 core
taken from the prescaler. The clock source for the prescaler is either the PCLK or the
nominal 400 kHz watchdog oscillator. The watchdog timer can only be reset by a
power-on reset. When the watchdog timer feature is disabled, it can be used as an interval
timer and may generate an interrupt. Figure 17 shows the watchdog timer in Watchdog
mode. Feeding the watchdog timer requires a two-byte sequence. If PCLK is selected as
the watchdog timer clock and the CPU is powered-down, the watchdog timer is disabled.
The watchdog timer has a time-out period that ranges from a few µs to a few seconds.
Please refer to the P89LPC9102/9103/9107 User manual UM10112 for more details.

8.25 Additional features
8.25.1 Software reset
The SRST bit in AUXR1 gives software the opportunity to reset the processor completely,
as if an external reset or watchdog timer reset had occurred. Care should be taken when
writing to AUXR1 to avoid accidental software resets.
8.25.2 Dual data pointers
The dual Data Pointers (DPTR) provides two different Data Pointers to specify the address
used with certain instructions. The DPS bit in the AUXR1 register selects one of the two
Data Pointers. Bit 2 of AUXR1 is permanently wired as a logic 0 so that the DPS bit may
be toggled (thereby switching Data Pointers) simply by incrementing the AUXR1 register,
without the possibility of inadvertently altering other bits in the register.

8.26 Flash program memory
8.26.1 General description
The P89LPC9102/9103/9107 flash memory provides in-circuit electrical erasure and
programming. The flash can be erased, read, and written as bytes. The Sector and Page
Erase functions can erase any flash sector (256 bytes) or page (16 bytes). The Chip
Erase operation will erase the entire program memory. In-Circuit Programming using
standard commercial programmers is available. In addition, In-Application Programming
Lite (IAP-Lite) and byte erase allows code memory to be used for non-volatile data
storage. On-chip erase and write timing generation contribute to a user-friendly
programming interface. The P89LPC9102/9103/9107 flash reliably stores memory
contents even after more than 400000 erase and program cycles. The cell is designed to
optimize the erase and programming mechanisms. The P89LPC9102/9103/9107 uses
VDD as the supply voltage to perform the Program/Erase algorithms.
8.26.2 Features

Programmable security for the code in the flash for each sector.
More than 400000 minimum erase/program cycles for each byte.
20-year minimum data retention.
8.26.3 Flash organization
The P89LPC9102/9103/9107 program memory consists of four 256 byte sectors. Each
sector can be further divided into 16-byte pages. In addition to sector erase, page erase,
and byte erase, a 16-byte page register is included which allows from 1 byte to 16 bytes of
a given page to be programmed at the same time, substantially reducing overall
programming time. In addition, erasing and reprogramming of user-programmable
configuration bytes including UCFG1, the Boot Status Bit, and the Boot Vector is
supported.
8.26.4 Flash programming and erasing
Different methods of erasing or programming of the flash are available. The flash may be
programmed or erased in the end-user application (IAP-Lite) under control of the
application’s firmware. Another option is to use the ICP mechanism. This ICP system
provides for programming through a serial clock- serial data interface. Third, the flash may
be programmed or erased using a commercially available EPROM programmer which
supports this device. This device does not provide for direct verification of code memory
contents. Instead this device provides a 32-bit CRC result on either a sector or the entire
1 kB of user code space.

8.26.5 In-circuit programming
In-Circuit Programming is performed without removing the microcontroller from the
system. The In-Circuit Programming facility consists of internal hardware resources to
facilitate remote programming of the P89LPC9102/9103/9107 through a two-wire serial
interface. The NXP In-Circuit Programming facility has made in-circuit programming in an
embedded application, using commercially available programmers, possible with a
minimum of additional expense in components and circuit board area. The ICP function
uses five pins. Only a small connector needs to be available to interface your application
to a commercial programmer in order to use this feature. Additional details may be found
in the P89LPC9102/9103/9107 User manual UM10112.
8.26.6 In-application programming (IAP-Lite)
In-Application Programming is performed in the application under the control of the
microcontroller’s firmware. The IAP facility consists of internal hardware resources to
facilitate programming and erasing. The NXP In-Application Programming (IAP-Lite) has
made in-application programming in an embedded application possible without additional
components. This is accomplished through the use of four SFRs consisting of a
control/status register, a data register, and two address registers. Additional details may
be found in the P89LPC9102/9103/9107 User manual UM10112.
8.26.7 Using flash as data storage
The flash code memory array of this device supports individual byte erasing and
programming. Any byte in the code memory array may be read using the MOVC
instruction, provided that the sector containing the byte has not been secured (a MOVC
instruction is not allowed to read code memory contents of a secured sector). Thus any
byte in a non-secured sector may be used for non-volatile data storage.
8.26.8 User configuration bytes
Some user-configurable features of the P89LPC9102/9103/9107 must be defined at
power-up and therefore cannot be set by the program after start of execution. These
features are configured through the use of the flash byte UCFG1. Please see the
P89LPC9102/9103/9107 User manual UM10112 for additional details.
8.26.9 User sector security bytes
There are four user sector security bytes, each corresponding to one sector. Please see
the P89LPC9102/9103/9107 User manual UM10112 for additional details.

9. A/D Converter
9.1 General description
The P89LPC9102/9103/9107 has an 8-bit, 4-channel multiplexed successive
approximation analog-to-digital converter. The A/D consists of a 4-input multiplexer which
feeds a sample-and-hold circuit providing an input signal to one of two comparator inputs.
The control logic in combination with the Successive Approximation Register (SAR) drives
a digital-to-analog converter which provides the other input to the comparator. The output
of the comparator is fed to the SAR. A block diagram of the A/D converter is shown in
Figure 18.

9.4 A/D operating modes
9.4.1 Fixed channel, single conversion mode
A single input channel can be selected for conversion. A single conversion will be
performed and the result placed in the result register which corresponds to the selected
input channel. An interrupt, if enabled, will be generated after the conversion completes.
9.4.2 Fixed channel, continuous conversion mode
A single input channel can be selected for continuous conversion. The results of the
conversions will be sequentially placed in the four result registers. An interrupt, if enabled,
will be generated after every four conversions. Additional conversion results will again
cycle through the four result registers, overwriting the previous results. Continuous
conversions continue until terminated by the user.
9.4.3 Auto scan, single conversion mode
Any combination of the four input channels can be selected for conversion. A single
conversion of each selected input will be performed and the result placed in the result
register which corresponds to the selected input channel. An interrupt, if enabled, will be
generated after all selected channels have been converted. If only a single channel is
selected this is equivalent to single channel, single conversion mode.
9.4.4 Auto scan, continuous conversion mode
Any combination of the four input channels can be selected for conversion. A conversion
of each selected input will be performed and the result placed in the result register which
corresponds to the selected input channel. An interrupt, if enabled, will be generated after
all selected channels have been converted. The process will repeat starting with the first
selected channel. Additional conversion results will again cycle through the four result
registers, overwriting the previous results. Continuous conversions continue until
terminated by the user.

9.4.5 Dual channel, continuous conversion mode
This is a variation of the auto scan continuous conversion mode where conversion occurs
on two user-selectable inputs. The result of the conversion of the first channel is placed in
result register, AD1DAT0. The result of the conversion of the second channel is placed in
result register, AD1DAT1. The first channel is again converted and its result stored in
AD1DAT2. The second channel is again converted and its result placed in AD1DAT3. An
interrupt is generated, if enabled, after every set of four conversions (two conversions per
channel).
9.4.6 Single step mode
This special mode allows ‘single-stepping’ in an auto scan conversion mode. Any
combination of the four input channels can be selected for conversion. After each channel
is converted, an interrupt is generated, if enabled, and the A/D waits for the next start
condition. May be used with any of the start modes.
9.5 Conversion start modes
9.5.1 Timer triggered start
An A/D conversion is started by the overflow of Timer 0. Once a conversion has started,
additional Timer 0 triggers are ignored until the conversion has completed. The Timer
triggered start mode is available in all A/D operating modes.
9.5.2 Start immediately
Programming this mode immediately starts a conversion. This start mode is available in all
A/D operating modes.
9.6 Boundary limits interrupt
The A/D converter has both a high and low boundary limit register. After the four MSBs
have been converted, these four bits are compared with the four MSBs of the boundary
high and low registers. If the four MSBs of the conversion are outside the limit an interrupt
will be generated, if enabled. If the conversion result is within the limits, the boundary
limits will again be compared after all 8 bits have been converted. An interrupt will be
generated, if enabled, if the result is outside the boundary limits. The boundary limit may
be disabled by clearing the boundary limit interrupt enable.
9.7 DAC output to a port pin with high output impedance
The A/D converter’s DAC block can be output to a port pin. In this mode, the AD1DAT3
register is used to hold the value fed to the DAC. After a value has been written to the DAC
(written to AD1DAT3), the DAC output will appear on the channel 3 pin.
9.8 Clock divider
The A/D converter requires that its internal clock source be in the range of 500 kHz to
3.3 MHz to maintain accuracy. A programmable clock divider that divides the clock
from 1 to 8 is provided for this purpose.

9.9 Power-down and Idle mode
In Idle mode the A/D converter, if enabled, will continue to function and can cause the
device to exit Idle mode when the conversion is completed if the A/D interrupt is enabled.
In Power-down mode or Total Power-down mode, the A/D does not function. If the A/D is
enabled, it will consume power. Power can be reduced by disabling the A/D.
