32-bit ARM Cortex-M0 microcontroller
7. Functional description
7.1 ARM Cortex-M0 processor
The ARM Cortex-M0 is a general purpose, 32-bit microprocessor, which offers high
performance and very low power consumption.
7.2 On-chip flash program memory
The LPC1102/1104 contain 32 kB of on-chip flash memory.
Remark: The LPC1102 supports In-Application Programming (IAP) and In-System
Programming (ISP). For ISP, since there is no dedicated ISP entry pin, user code is
required to invoke ISP functionality. Unprogrammed parts will automatically boot into ISP
mode.
7.3 On-chip SRAM
The LPC1102/1104 contain 8 kB on-chip static RAM memory.
7.4 Memory map
The LPC1102/1104 incorporate several distinct memory regions, shown in the following
figures. Figure 3 shows the overall map of the entire address space from the user
program viewpoint following reset. The interrupt vector area supports address remapping.
The AHB peripheral area is 2 MB in size, and is divided to allow for up to 128 peripherals.
The APB peripheral area is 512 kB in size and is divided to allow for up to 32 peripherals.
Each peripheral of either type is allocated 16 kB of space. This allows simplifying the
address decoding for each peripheral.

7.5 Nested Vectored Interrupt Controller (NVIC)
The Nested Vectored Interrupt Controller (NVIC) is an integral part of the Cortex-M0. The
tight coupling to the CPU allows for low interrupt latency and efficient processing of late
arriving interrupts.
7.5.1 Features
• Controls system exceptions and peripheral interrupts.
• In the LPC1102/1104, the NVIC supports 19 vectored interrupts including up to 6
inputs to the start logic from individual GPIO pins.

LPC1102/1104
NXP Semiconductors
32-bit ARM Cortex-M0 microcontroller
• Four programmable interrupt priority levels, with hardware priority level masking.
• Software interrupt generation.
7.5.2 Interrupt sources
Each peripheral device has one interrupt line connected to the NVIC but may have several
interrupt flags. Individual interrupt flags may also represent more than one interrupt
source.
Any GPIO pin (total of up to 11 pins) regardless of the selected function, can be
programmed to generate an interrupt on a level, or rising edge or falling edge, or both.
7.6 IOCONFIG block
The IOCONFIG block allows selected pins of the microcontroller to have more than one
function. Configuration registers control the multiplexers to allow connection between the
pin and the on-chip peripherals.
Peripherals should be connected to the appropriate pins prior to being activated and prior
to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is
not mapped to a related pin should be considered undefined.
7.7 Fast general purpose parallel I/O
Device pins that are not connected to a specific peripheral function are controlled by the
GPIO registers. Pins may be dynamically configured as inputs or outputs. Multiple outputs
can be set or cleared in one write operation.
The LPC1102/1104 use accelerated GPIO functions:
• GPIO registers are a dedicated AHB peripheral so that the fastest possible I/O timing
can be achieved.
• Entire port value can be written in one instruction.
Additionally, any GPIO pin (total of 11 pins) providing a digital function can be
programmed to generate an interrupt on a level, a rising or falling edge, or both.
7.7.1 Features
• Bit level port registers allow a single instruction to set or clear any number of bits in
one write operation.
• Direction control of individual bits.
• All I/O default to inputs with pull-ups enabled after reset.
• Pull-up/pull-down resistor configuration can be programmed through the IOCONFIG
block for each GPIO pin.
• All GPIO pins are pulled up to 3.3 V (VDD = 3.3 V) if their pull-up resistor is enabled in
the IOCONFIG block.
• Programmable open-drain mode.
7.8 UART
The LPC1102/1104 contain one UART.

LPC1102/1104
NXP Semiconductors
32-bit ARM Cortex-M0 microcontroller
Support for RS-485/9-bit mode allows both software address detection and automatic
address detection using 9-bit mode.
The UART includes a fractional baud rate generator. Standard baud rates such as
115200 Bd can be achieved with any crystal frequency above 2 MHz.
7.8.1 Features
•

•
•
•
Maximum UART data bit rate of 3.125 Mbit/s.
16 Byte Receive and Transmit FIFOs.
Register locations conform to 16C550 industry standard.
Receiver FIFO trigger points at 1 B, 4 B, 8 B, and 14 B.
Built-in fractional baud rate generator covering wide range of baud rates without a
need for external crystals of particular values.
• FIFO control mechanism that enables software flow control implementation.
• Support for RS-485/9-bit mode.
7.9 SPI serial I/O controller
The LPC1102/1104 contain one SPI controller and fully supports SSP features.
The SPI controller is capable of operation on a SSP, 4-wire SSI, or Microwire bus. It can
interact with multiple masters and slaves on the bus. Only a single master and a single
slave can communicate on the bus during a given data transfer. The SPI supports full
duplex transfers, with frames of 4 bits to 16 bits of data flowing from the master to the
slave and from the slave to the master. In practice, often only one of these data flows
carries meaningful data.
Remark: Care must be taken when using the SPI because the SPI clock SCK and the
serial wire debug clock SWCLK share the same pin on the WLCSP16 package. Once the
SPI is enabled, the serial wire debugger is no longer available (LPC1102 only).
7.9.1 Features
• Maximum SPI speed of 25 Mbit/s (master) or 4.17 Mbit/s (slave) (in SSP mode)
• Compatible with Motorola SPI, 4-wire Texas Instruments SSI, and National
Semiconductor Microwire buses
•
•
•
•
Synchronous serial communication
Master or slave operation
8-frame FIFOs for both transmit and receive
4-bit to 16-bit frame
7.10 10-bit ADC
The LPC1102/1104 contain one ADC. It is a single 10-bit successive approximation ADC
with five channels.
7.10.1 Features
• 10-bit successive approximation ADC.

7.11 General purpose external event counter/timers
The LPC1102/1104 include two 32-bit counter/timers and two 16-bit counter/timers. The
counter/timer is designed to count cycles of the system derived clock. It can optionally
generate interrupts or perform other actions at specified timer values, based on four
match registers. Each counter/timer also includes one capture input to trap the timer value
when an input signal transitions, optionally generating an interrupt.

7.14 Clocking and power control
7.14.1 Crystal oscillators
The LPC1102/1104 include two independent oscillators. These are the Internal RC
oscillator (IRC) and the Watchdog oscillator. Each oscillator can be used for more than
one purpose as required in a particular application.
Following reset, the LPC1102/1104 operate from the Internal RC oscillator until switched
by software. This allows systems to operate without any external crystal and the
bootloader code to operate at a known frequency.
See Figure 4 for an overview of the LPC1102/1104 clock generation.

LPC1102/1104 clock generation block diagram
7.14.1.1
Internal RC oscillator
The IRC may be used as the clock source for the WDT, and/or as the clock that drives the
PLL and subsequently the CPU. The nominal IRC frequency is 12 MHz. The IRC is
trimmed to 1 % accuracy over the entire voltage and temperature range.
Upon power-up or any chip reset, the LPC1102/1104 use the IRC as the clock source.
Software may later switch to one of the other available clock sources.
7.14.1.2
Watchdog oscillator
The watchdog oscillator can be used as a clock source that directly drives the CPU or the
watchdog timer. The watchdog oscillator nominal frequency is programmable between
9.4 kHz to 2.3 MHz. The frequency spread over processing and temperature is 40 %.
7.14.2 System PLL
The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input
frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO).
The multiplier can be an integer value from 1 to 32. The CCO operates in the range of
156 MHz to 320 MHz, so there is an additional divider in the loop to keep the CCO within

32-bit ARM Cortex-M0 microcontroller
its frequency range while the PLL is providing the desired output frequency. The PLL
output frequency must be lower than 100 MHz. The output divider may be set to divide by
2, 4, 8, or 16 to produce the output clock. Since the minimum output divider value is 2, it is
insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed
following a chip reset and may be enabled by software. The program must configure and
activate the PLL, wait for the PLL to lock, and then connect to the PLL as a clock source.
The PLL settling time is 100 s.
7.14.3 Clock output (LPC1104 only)
The LPC1104 features a clock output function that routes the IRC oscillator, the system
oscillator, the watchdog oscillator, or the main clock to an output pin.
7.14.4 Wake-up process
The LPC1102/1104 begin operation at power-up by using the 12 MHz IRC oscillator as the
clock source. This allows chip operation to resume quickly. If an external clock or the PLL
is needed by the application, software will need to enable these features and wait for them
to stabilize before they are used as a clock source.
7.14.5 Power control
The LPC1102/1104 support a variety of power control features. There are two special
modes of processor power reduction: Sleep mode and Deep-sleep mode. The CPU clock
rate may also be controlled as needed by changing clock sources, reconfiguring PLL
values, and/or altering the CPU clock divider value. This allows a trade-off of power
versus processing speed based on application requirements. In addition, a register is
provided for shutting down the clocks to individual on-chip peripherals, allowing fine tuning
of power consumption by eliminating all dynamic power use in any peripherals that are not
required for the application. Selected peripherals have their own clock divider which
provides even better power control.
7.14.5.1
Power profiles
The power consumption in Active and Sleep modes can be optimized for the application
through a simple call to the power profiles. The power configuration routine configures the
LPC1102/1104 for one of the following power modes:
• Default mode corresponding to power configuration after reset.
• CPU performance mode corresponding to optimized processing capability.
• Efficiency mode corresponding to optimized balance of current consumption and CPU
performance.
• Low-current mode corresponding to lowest power consumption.
In addition, the power profiles includes a routine to select the optimal PLL settings for a
given system clock and PLL input clock.
7.14.5.2
Sleep mode
When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep
mode does not need any special sequence but re-enabling the clock to the ARM core.

LPC1102/1104
NXP Semiconductors
32-bit ARM Cortex-M0 microcontroller
In Sleep mode, execution of instructions is suspended until either a reset or interrupt
occurs. Peripheral functions continue operation during Sleep mode and may generate
interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic
power used by the processor itself, memory systems and related controllers, and internal
buses.
7.14.5.3
Deep-sleep mode
In Deep-sleep mode, the chip is in Sleep mode, and in addition all analog blocks are shut
down except for the watchdog oscillator and the BOD circuit, which can be configured to
remain running in Deep-sleep mode to allow a reset initiated by a timer or BOD event.
Deep-sleep mode allows for additional power savings.
Six of the GPIO pins (see Table 3) serve as external wake-up pins to a dedicated start
logic to wake up the chip from Deep-sleep mode.
The clock source should be switched to IRC before entering Deep-sleep mode unless the
watchdog oscillator remains running in Deep-sleep mode. The IRC can be switched on
and off glitch-free and provides a clean clock signal after start-up.
7.15 System control
7.15.1 Start logic
The start logic connects external pins to corresponding interrupts in the NVIC. Each pin
shown in Table 3 as input to the start logic has an individual interrupt in the NVIC interrupt
vector table. The start logic pins can serve as external interrupt pins when the chip is
running. In addition, an input signal on the start logic pins can wake up the chip from
Deep-sleep mode when all clocks are shut down.
The start logic must be configured in the system configuration block and in the NVIC
before being used.
7.15.2 Reset
Reset has four sources on the LPC1102/1104: the RESET pin, the Watchdog reset,
Power-On Reset (POR), and the BrownOut Detection (BOD) circuit. In addition, there is
an ARM software reset. The RESET pin is a Schmitt trigger input pin. Assertion of chip
reset by any source, once the operating voltage attains a usable level, starts the IRC and
initializes the flash controller.
A LOW-going pulse as short as 50 ns resets the part.
When the internal Reset is removed, the processor begins executing at address 0, which
is initially the Reset vector mapped from the boot block. At that point, all of the processor
and peripheral registers have been initialized to predetermined values.
7.15.3 Brownout detection
The LPC1102/1104 include up to four levels for monitoring the voltage on the VDD pin. If
this voltage falls below one of the three selected levels, the BOD asserts an interrupt
signal to the NVIC. This signal can be enabled for interrupt in the Interrupt Enable
Register in the NVIC in order to cause a CPU interrupt; if not, software can monitor the
signal by reading a dedicated status register. Four additional threshold levels can be
selected to cause a forced reset of the chip.

7.15.4 Code security (Code Read Protection - CRP)
This feature of the LPC1102/1104 allow user to enable different levels of security in the
system so that access to the on-chip flash and use of the Serial Wire Debugger (SWD)
can be restricted. When needed, CRP is invoked by programming a specific pattern into a
dedicated flash location. IAP commands are not affected by the CRP.
There are three levels of Code Read Protection:
1. CRP1 disables access to the chip via the SWD and allows partial flash update
(excluding flash sector 0). This mode is useful when CRP is required and flash field
updates are needed but all sectors can not be erased.
2. CRP2 disables access to the chip via the SWD and only allows full flash erase and
update.
3. Running an application with level CRP3 selected fully disables any access to the chip
via the SWD pins.
Remark: The LPC1102 does not provide an ISP entry pin to be monitored at reset. For all
three CRP levels, the user’s application code must provide a flash update mechanism
which reinvokes ISP by defining a user-selected PIOn pin for ISP entry.
CAUTION
If Code Read Protection of any level (CRP1, CRP2 or CRP3) is selected, no future factory
testing can be performed on the device.
7.15.5 APB interface
The APB peripherals are located on one APB bus.
7.15.6 AHBLite
The AHBLite connects the CPU bus of the ARM Cortex-M0 to the flash memory, the main
static RAM, and the Boot ROM.
7.15.7 External interrupt inputs
All GPIO pins can be level or edge sensitive interrupt inputs. In addition, start logic inputs
serve as external interrupts (see Section 7.15.1).
7.16 Emulation and debugging
Debug functions are integrated into the ARM Cortex-M0. Serial wire debug with four
breakpoints and two watchpoints is supported.
Remark: Care must be taken when using the SPI because the SPI clock SCK and the
serial wire debug clock SWCLK share the same pin on the WLCSP16 package. Once the
SPI is enabled, the serial wire debugger is no longer available (LPC1102 only).

9.2 Power consumption
Power measurements in Active, Sleep, and Deep-sleep modes were performed under the
following conditions (see user manual UM10429):
• All digital pins configured as GPIO with pull-up resistor disabled in the IOCONFIG
block.
• GPIO pins configured as outputs using the GPIOnDIR registers.
• Write 0 to all GPIOnDATA registers to drive the outputs LOW.
• Write a 1 to bit 4 and bit 5 of the GPIO0DIR register at location 0x5000 8000 and a 0
to bit 4 and bit 5 of the GPIO0DATA register at location 0x5000 3FFC. This ensures
that not-bonded out pins are in a well-defined state.

11. Application information
11.1 ADC usage notes
The following guidelines show how to increase the performance of the ADC in a noisy
environment beyond the ADC specifications listed in Table 6:
• The ADC input trace must be short and as close as possible to the LPC1102/1104
chip.
• The ADC input traces must be shielded from fast switching digital signals and noisy
power supply lines.
• Because the ADC and the digital core share the same power supply, the power supply
line must be adequately filtered.
• To improve the ADC performance in a very noisy environment, put the device in Sleep
mode during the ADC conversion.
11.2 XTAL input
The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a
clock in slave mode, it is recommended that the input be coupled through a capacitor with
Ci = 100 pF. To limit the input voltage to the specified range, choose an additional
capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave
mode, a minimum of 200 mV (RMS) is needed.

XTALIN
Ci
100 pF
Cg
002aae788
Fig 20. Slave mode operation of the on-chip oscillator
In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF
(Figure 20), with an amplitude between 200 mV (RMS) and 1000 mV (RMS). This
corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V.

Fig 23. ADC input channel
The effective input impedance, Rin, seen by the external voltage source, VEXT, is the
parallel impedance of ((1/fs x Cia) + Rmux + Rsw) and (1/fs x Cio), and can be calculated
using Equation 1 with
fs = sampling frequency
Cia = ADC analog input capacitance
Rmux = analog mux resistance
Rsw = switch resistance
Cio = pin capacitance

R in =  ------------------ + R mux + R sw   ------------------
 f s  C ia
  f s  C io
(1)
Under nominal operating condition VDD = 3.3 V and with the maximum sampling
frequency fs = 400 kHz, the parameters assume the following values:
Cia = 1 pF (max)
Rmux = 2 kΩ (max)
Rsw = 1.3 kΩ (max)
Cio = 7.1 pF (max)
The effective input impedance with these parameters is Rin = 308 kΩ.
