Rev. 01 — 09 February 2004
Preliminary data
1. General description
The LPC2290 is based on a 16/32 bit ARM7TDMI-S™ CPU with real-time emulation
and embedded trace support. For critical code size applications, the alternative 16-bit
Thumb Mode reduces code by more than 30% with minimal performance penalty.
With its 144 pin package, low power consumption, various 32-bit timers, 8-channel
10-bit ADC, 2 advanced CAN channels, PWM channels and up to 9 external interrupt
pins this microcontroller is particularly suitable for automotive and industrial control
applications as well as medical systems and fault-tolerant maintenance buses.
LPC2290 provides up to 76 GPIO depending on bus configuration. With a wide range
of additional serial communications interfaces, it is also suited for communication
gateways and protocol converters as well as many other general-purpose
applications.

Philips Semiconductors
16/32-bit ARM microcontrollers with external memory interface
6. Functional description
Details of the LPC2290 systems and peripheral functions are described in the
following sections.
6.1 Architectural overview
The ARM7TDMI-S is a general purpose 32-bit microprocessor, which offers high
performance and very low power consumption. The ARM architecture is based on
Reduced Instruction Set Computer (RISC) principles, and the instruction set and
related decode mechanism are much simpler than those of microprogrammed
Complex Instruction Set Computers. This simplicity results in a high instruction
throughput and impressive real-time interrupt response from a small and
cost-effective processor core.
Pipeline techniques are employed so that all parts of the processing and memory
systems can operate continuously. Typically, while one instruction is being executed,
its successor is being decoded, and a third instruction is being fetched from memory.
The ARM7TDMI-S processor also employs a unique architectural strategy known as
THUMB, which makes it ideally suited to high-volume applications with memory
restrictions, or applications where code density is an issue.
The key idea behind THUMB is that of a super-reduced instruction set. Essentially,
the ARM7TDMI-S processor has two instruction sets:
• The standard 32-bit ARM set.
• A 16-bit THUMB set.
The THUMB set’s 16-bit instruction length allows it to approach twice the density of
standard ARM code while retaining most of the ARM’s performance advantage over a
traditional 16-bit processor using 16-bit registers. This is possible because THUMB
code operates on the same 32-bit register set as ARM code.
THUMB code is able to provide up to 65% of the code size of ARM, and 160% of the
performance of an equivalent ARM processor connected to a 16-bit memory system.
6.2 On-Chip static RAM
On-Chip static RAM may be used for code and/or data storage. The SRAM may be
accessed as 8-bits, 16-bits, and 32-bits. The LPC2290 provides 16 kB of static RAM.
6.3 Memory map
The LPC2290 memory maps incorporate several distinct regions, as shown in the
following figures.
In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in
either on-chip boot-loader, external memory BANK0 or on-chip static RAM. This is
described in Section 6.20 “System control”.

6.4 Interrupt controller
The Vectored Interrupt Controller (VIC) accepts all of the interrupt request inputs and
categorizes them as FIQ, vectored IRQ, and non-vectored IRQ as defined by
programmable settings. The programmable assignment scheme means that priorities
of interrupts from the various peripherals can be dynamically assigned and adjusted.
Fast Interrupt reQuest (FIQ) has the highest priority. If more than one request is
assigned to FIQ, the VIC combines the requests to produce the FIQ signal to the
ARM processor. The fastest possible FIQ latency is achieved when only one request
is classified as FIQ, because then the FIQ service routine can simply start dealing
with that device. But if more than one request is assigned to the FIQ class, the FIQ
service routine can read a word from the VIC that identifies which FIQ source(s) is
(are) requesting an interrupt.

LPC2290
Philips Semiconductors
16/32-bit ARM microcontrollers with external memory interface
Vectored IRQs have the middle priority. Sixteen of the interrupt requests can be
assigned to this category. Any of the interrupt requests can be assigned to any of the
16 vectored IRQ slots, among which slot 0 has the highest priority and slot 15 has the
lowest.
Non-vectored IRQs have the lowest priority.
The VIC combines the requests from all the vectored and non-vectored IRQs to
produce the IRQ signal to the ARM processor. The IRQ service routine can start by
reading a register from the VIC and jumping there. If any of the vectored IRQs are
requesting, the VIC provides the address of the highest-priority requesting IRQs
service routine, otherwise it provides the address of a default routine that is shared by
all the non-vectored IRQs. The default routine can read another VIC register to see
what IRQs are active.
6.4.1
Interrupt sources
Table 4 lists the interrupt sources for each peripheral function. Each peripheral device
has one interrupt line connected to the Vectored Interrupt Controller, but may have
several internal interrupt flags. Individual interrupt flags may also represent more than
one interrupt source.

6.5 Pin connect block
The pin connect 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.
The Pin Control Module contains three registers as shown in Table 5.

6.9 External memory controller
The external Static Memory Controller is a module which provides an interface
between the system bus and external (off-chip) memory devices. It provides support
for up to four independently configurable memory banks (16 MBytes each with byte
lane enable control) simultaneously. Each memory banks is capable of supporting
SRAM, ROM, Flash EPROM, Burst ROM memory, or some external I/O devices.
Each memory bank may be 8, 16, or 32 bits wide.
6.10 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.
Separate registers allow setting or clearing any number of outputs simultaneously.
The value of the output register may be read back, as well as the current state of the
port pins.

6.14 I2C serial I/O controller
I2C is a bi-directional bus for inter-IC control using only two wires: a serial clock line
(SCL), and a serial data line (SDA). Each device is recognized by a unique address
and can operate as either a receiver-only device (e.g. an LCD driver or a transmitter
with the capability to both receive and send information (such as memory).
Transmitters and/or receivers can operate in either master or slave mode, depending
on whether the chip has to initiate a data transfer or is only addressed. I2C is a
multi-master bus, it can be controlled by more than one bus master connected to it.
I2C implemented in LPC2290 supports bit rate up to 400 kbit/s (Fast I2C).
6.14.1
Features
• Standard I2C compliant bus interface.
• Easy to configure as Master, Slave, or Master/Slave.
• Programmable clocks allow versatile rate control.
• Bidirectional data transfer between masters and slaves.
• Multi-master bus (no central master).
• Arbitration between simultaneously transmitting masters without corruption of
serial data on the bus.
• Serial clock synchronization allows devices with different bit rates to communicate
via one serial bus.
• Serial clock synchronization can be used as a handshake mechanism to suspend
and resume serial transfer.
• The I2C bus may be used for test and diagnostic purposes.
6.15 SPI serial I/O controller
The LPC2290 contains two SPIs. The SPI is a full duplex serial interface, designed to
be able to handle multiple masters and slaves connected to a given bus. Only a single
master and a single slave can communicate on the interface during a given data
transfer. During a data transfer the master always sends a byte of data to the slave,
and the slave always sends a byte of data to the master.
6.15.1
Features
• Compliant with Serial Peripheral Interface (SPI) specification.
• Synchronous, Serial, Full Duplex, Communication.
• Combined SPI master and slave.
• Maximum data bit rate of one eighth of the input clock rate.

6.16 General purpose timers
The Timer is designed to count cycles of the peripheral clock (PCLK) and optionally
generate interrupts or perform other actions at specified timer values, based on four
match registers. It also includes four capture inputs to trap the timer value when an
input signal transitions, optionally generating an interrupt. Multiple pins can be
selected to perform a single capture or match function, providing an application with
‘or’ and ‘and’, as well as ‘broadcast’ functions among them.
6.16.1
Features
• A 32-bit Timer/Counter with a programmable 32-bit Prescaler.
• Four 32-bit capture channels per timer that can take a snapshot of the timer value
when an input signal transitions. A capture event may also optionally generate an
interrupt.
• Four 32-bit match registers that allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Four external outputs per timer corresponding to match registers, with the following
capabilities:
– Set LOW on match.
– Set HIGH on match.
– Toggle on match.
– Do nothing on match.
6.17 Watchdog timer
The purpose of the Watchdog is to reset the microcontroller within a reasonable
amount of time if it enters an erroneous state. When enabled, the Watchdog will
generate a system reset if the user program fails to ‘feed’ (or reload) the Watchdog
within a predetermined amount of time.
6.17.1
Features
• Internally resets chip if not periodically reloaded.
• Debug mode.
• Enabled by software but requires a hardware reset or a Watchdog reset/interrupt to
be disabled.
• Incorrect/Incomplete feed sequence causes reset/interrupt if enabled.
• Flag to indicate Watchdog reset.
• Programmable 32-bit timer with internal pre-scaler.
• Selectable time period from (tpclk × 256 × 4) to (tpclk × 232 × 4) in multiples of
tpclk × 4.

6.18 Real time clock
The Real Time Clock (RTC) is designed to provide a set of counters to measure time
when normal or idle operating mode is selected. The RTC has been designed to use
little power, making it suitable for battery powered systems where the CPU is not
running continuously (Idle mode).
6.18.1
Features
• Measures the passage of time to maintain a calendar and clock.
• Ultra Low Power design to support battery powered systems.
• Provides Seconds, Minutes, Hours, Day of Month, Month, Year, Day of Week, and
Day of Year.
• Programmable Reference Clock Divider allows adjustment of the RTC to match
various crystal frequencies.
6.19 Pulse width modulator
The PWM is based on the standard Timer block and inherits all of its features, although
only the PWM function is pinned out on the LPC2290. The Timer is designed to count
cycles of the peripheral clock (PCLK) and optionally generate interrupts or perform
other actions when specified timer values occur, based on seven match registers. The
PWM function is also based on match register events.
The ability to separately control rising and falling edge locations allows the PWM to
be used for more applications. For instance, multi-phase motor control typically
requires three non-overlapping PWM outputs with individual control of all three pulse
widths and positions.
Two match registers can be used to provide a single edge controlled PWM output.
One match register (MR0) controls the PWM cycle rate, by resetting the count upon
match. The other match register controls the PWM edge position. Additional single
edge controlled PWM outputs require only one match register each, since the
repetition rate is the same for all PWM outputs. Multiple single edge controlled PWM
outputs will all have a rising edge at the beginning of each PWM cycle, when an MR0
match occurs.
Three match registers can be used to provide a PWM output with both edges
controlled. Again, the MR0 match register controls the PWM cycle rate. The other
match registers control the two PWM edge positions. Additional double edge
controlled PWM outputs require only two match registers each, since the repetition
rate is the same for all PWM outputs.
With double edge controlled PWM outputs, specific match registers control the rising
and falling edge of the output. This allows both positive going PWM pulses (when the
rising edge occurs prior to the falling edge), and negative going PWM pulses (when
the falling edge occurs prior to the rising edge).
6.19.1
Features
• Seven match registers allow up to six single edge controlled or three double edge
controlled PWM outputs, or a mix of both types.

• The match registers also allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Supports single edge controlled and/or double edge controlled PWM outputs.
Single edge controlled PWM outputs all go HIGH at the beginning of each cycle
unless the output is a constant LOW. Double edge controlled PWM outputs can
have either edge occur at any position within a cycle. This allows for both positive
going and negative going pulses.
• Pulse period and width can be any number of timer counts. This allows complete
flexibility in the trade-off between resolution and repetition rate. All PWM outputs
will occur at the same repetition rate.
• Double edge controlled PWM outputs can be programmed to be either positive
going or negative going pulses.
• Match register updates are synchronized with pulse outputs to prevent generation
of erroneous pulses. Software must ‘release’ new match values before they can
become effective.
• May be used as a standard timer if the PWM mode is not enabled.
• A 32-bit Timer/Counter with a programmable 32-bit Prescaler.
6.20 System control
6.20.1
Crystal oscillator
The oscillator supports crystals in the range of 1 MHz to 30 MHz. The oscillator
output frequency is called fosc and the ARM processor clock frequency is referred to
as cclk for purposes of rate equations, etc. fosc and cclk are the same value unless
the PLL is running and connected. Refer to Section 6.20.2 “PLL” for additional
information.
6.20.2
PLL
The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The
input frequency is multiplied up into the range of 10 MHz to 60 MHz with a Current
Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32 (in
practice, the multiplier value cannot be higher than 6 on this family of microcontrollers
due to the upper frequency limit of the CPU). 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 its frequency range while the PLL is providing the desired output frequency.
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, then connect to the PLL as a clock source.

6.20.3
Reset and wake-up timer
Reset has two sources on the LPC2290: the RESET pin and Watchdog Reset. The
RESET pin is a Schmitt trigger input pin with an additional glitch filter. Assertion of
chip Reset by any source starts the Wake-up Timer (see Wake-up Timer description
below), causing the internal chip reset to remain asserted until the external Reset is
de-asserted, the oscillator is running, a fixed number of clocks have passed, and the
on-chip circuitry has completed its initialization.
When the internal Reset is removed, the processor begins executing at address 0,
which is the Reset vector. At that point, all of the processor and peripheral registers
have been initialized to predetermined values.
The wake-up timer ensures that the oscillator and other analog functions required for
chip operation are fully functional before the processor is allowed to execute
instructions. This is important at power on, all types of Reset, and whenever any of
the aforementioned functions are turned off for any reason. Since the oscillator and
other functions are turned off during Power-down mode, any wake-up of the
processor from Power-down mode makes use of the Wake-up Timer.
The Wake-up Timer monitors the crystal oscillator as the means of checking whether
it is safe to begin code execution. When power is applied to the chip, or some event
caused the chip to exit Power-down mode, some time is required for the oscillator to
produce a signal of sufficient amplitude to drive the clock logic. The amount of time
depends on many factors, including the rate of VDD ramp (in the case of power on),
the type of crystal and its electrical characteristics (if a quartz crystal is used), as well
as any other external circuitry (e.g. capacitors), and the characteristics of the
oscillator itself under the existing ambient conditions.
6.20.4
External interrupt inputs
The LPC2290 includes up to nine edge or level sensitive External Interrupt Inputs as
selectable pin functions. When the pins are combined, external events can be
processed as four independent interrupt signals. The External Interrupt Inputs can
optionally be used to wake up the processor from Power-down mode.
6.20.5
Memory Mapping Control
The Memory Mapping Control alters the mapping of the interrupt vectors that appear
beginning at address 0x00000000. Vectors may be mapped to the bottom of the
BANK0 external memory, or to the on-chip static RAM. This allows code running in
different memory spaces to have control of the interrupts.
6.20.6
Power Control
The LPC2290 supports two reduced power modes: Idle mode and Power-down
mode. In Idle mode, execution of instructions is suspended until either a Reset or
interrupt occurs. Peripheral functions continue operation during Idle mode and may
generate interrupts to cause the processor to resume execution. Idle mode eliminates
power used by the processor itself, memory systems and related controllers, and
internal buses.
In Power-down mode, the oscillator is shut down and the chip receives no internal
clocks. The processor state and registers, peripheral registers, and internal SRAM
values are preserved throughout Power-down mode and the logic levels of chip
output pins remain static. The Power-down mode can be terminated and normal

16/32-bit ARM microcontrollers with external memory interface
operation resumed by either a Reset or certain specific interrupts that are able to
function without clocks. Since all dynamic operation of the chip is suspended,
Power-down mode reduces chip power consumption to nearly zero.
A Power Control for Peripherals feature allows individual peripherals to be turned off if
they are not needed in the application, resulting in additional power savings.
6.20.7
VPB bus
The VPB Divider determines the relationship between the processor clock (cclk) and
the clock used by peripheral devices (PCLK). The VPB Divider serves two purposes.
The first is that the VPB bus cannot operate at the highest speeds of the CPU. In
order to compensate for this, the VPB bus may be slowed down to one half or one
fourth of the processor clock rate. The default condition at reset is for the VPB bus to
run at one quarter of the CPU clock. The second purpose of the VPB Divider is to
allow power savings when an application does not require any peripherals to run at
the full processor rate. Because the VPB Divider is connected to the PLL output, the
PLL remains active (if it was running) during Idle mode.
6.21 Emulation and debugging
The LPC2290 supports emulation and debugging via a JTAG serial port. A trace port
allows tracing program execution. Debugging and trace functions are multiplexed only
with GPIOs on Port 1. This means that all communication, timer and interface
peripherals residing on Port 0 are available during the development and debugging
phase as they are when the application is run in the embedded system itself.
6.21.1
Embedded ICE™
Standard ARM EmbeddedICE logic provides on-chip debug support. The debugging
of the target system requires a host computer running the debugger software and an
EmbeddedICE protocol convertor. EmbeddedICE protocol convertor converts the
Remote Debug Protocol commands to the JTAG data needed to access the ARM
core.
The ARM core has a Debug Communication Channel function built-in. The debug
communication channel allows a program running on the target to communicate with
the host debugger or another separate host without stopping the program flow or
even entering the debug state. The debug communication channel is accessed as a
co-processor 14 by the program running on the ARM7TDMI-S core. The debug
communication channel allows the JTAG port to be used for sending and receiving
data without affecting the normal program flow. The debug communication channel
data and control registers are mapped in to addresses in the EmbeddedICE™ logic.
6.21.2
Embedded trace
Since the LPC2290 has significant amounts of on-chip memory, it is not possible to
determine how the processor core is operating simply by observing the external pins.
The Embedded Trace Macrocell provides real-time trace capability for deeply
embedded processor cores. It outputs information about processor execution to the
trace port.
The ETM is connected directly to the ARM core and not to the main AMBA system
bus. It compresses the trace information and exports it through a narrow trace port.
An external trace port analyzer must capture the trace information under software

debugger control. Instruction trace (or PC trace) shows the flow of execution of the
processor and provides a list of all the instructions that were executed. Instruction
trace is significantly compressed by only broadcasting branch addresses as well as a
set of status signals that indicate the pipeline status on a cycle by cycle basis. Trace
information generation can be controlled by selecting the trigger resource. Trigger
resources include address comparators, counters and sequencers. Since trace
information is compressed the software debugger requires a static image of the code
being executed. Self-modifying code can not be traced because of this restriction.
6.21.3
RealMonitor™
RealMonitor is a configurable software module, developed by ARM Inc., which
enables real time debug. It is a lightweight debug monitor that runs in the background
while users debug their foreground application. It communicates with the host using
the DCC (Debug Communications Channel), which is present in the EmbeddedICE
logic. The LPC2290 contains a specific configuration of RealMonitor software
programmed into the on-chip memory.

The offset error (OSe) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the
ideal curve. See Figure 4.
The gain error (Ge) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset
error, and the straight line which fits the ideal transfer curve. See Figure 4.
The absolute voltage error (Ae) is the maximum difference between the center of the steps of the actual transfer curve of the
non-calibrated A/D and the ideal transfer curve. See Figure 4.
