with 10-bit ADC and external memory interface
Rev. 04 — 2 October 2007
Product data sheet
1. General description
The LPC2210/2220 microcontrollers are 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 their 144-pin package, low power consumption, various 32-bit timers, 8-channel
10-bit ADC, PWM channels, and up to nine external interrupt pins these microcontrollers
are particularly suitable for industrial control, medical systems, access control and
point-of-sale. The LPC2210/2220 can provide up to 76 GPIOs depending on bus
configuration. With a wide range of serial communications interfaces, it is also very well
suited for communication gateways, protocol converters and embedded soft modems as
well as many other general-purpose applications.

16/32-bit ARM microcontrollers with external memory interface
6. Functional description
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 RISC
principles, and the instruction set and related decode mechanism are much simpler than
those of microprogrammed CISC. 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 SRAM
On-chip SRAM may be used for code and/or data storage. The SRAM may be accessed
as 8 bit, 16 bit, and 32 bit. The LPC2210/2220 provide 16 kB of static RAM and the
LPC2220 provides 64 kB of static RAM.
6.3 Memory map
The LPC2210/2220 memory maps incorporate several distinct regions, as shown in
Figure 4.
In addition, the CPU interrupt vectors may be re-mapped to allow them to reside in either
on-chip bootloader, external memory BANK0 or on-chip static RAM. This is described in
Section 6.20 “System control”.

6.4 Interrupt controller
The VIC accepts all of the interrupt request inputs and categorizes them as Fast Interrupt
Request (FIQ), vectored Interrupt Request (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.
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.
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.

16/32-bit ARM microcontrollers with external memory interface
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 5 lists the interrupt sources for each peripheral function. Each peripheral device has
one interrupt line connected to the VIC, 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 6.

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 MB each with byte lane enable control)
simultaneously. Each memory bank is capable of supporting SRAM, ROM, flash EPROM,
burst ROM memory, or some external I/O devices.
Each memory bank may be 8-bit, 16-bit, or 32-bit 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.
6.10.1 Features
• Direction control of individual bits.
• Separate control of output set and clear.
• All I/O default to inputs after reset.
6.11 10-bit ADC
The LPC2210/2220 each contain a single 10-bit successive approximation ADC with eight
multiplexed channels.

only.
6.13 I2C-bus serial I/O controller
The I2C-bus is bidirectional 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. The I2C-bus is a multi-master bus, it can be
controlled by more than one bus master connected to it.
The I2C-bus implemented in LPC2210/2220 supports a bit rate up to 400 kbit/s (Fast
I2C-bus).
6.13.1 Features

6.14 SPI serial I/O controller
The LPC2210/2220 each contain 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
• Compatible with Motorola’s SPI, TI’s 4-wire SSI, and National Semiconductor’s
Microwire buses.
•
•
•
•
Synchronous serial communication.
Master or slave operation.
8-frame FIFOs for both transmit and receive.
Four to 16 bits per frame.
6.15.2 Description
The SSP is a controller capable of operation on a SPI, 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. Data transfers are in
principle full duplex, with frames of four to 16 bits of data flowing from the master to the
slave and from the slave to the master.
While the SSP and SPI1 peripherals share the same physical pins, it is not possible to
have both of these two peripherals active at the same time. Application can switch on the
fly from SPI1 to SSP and back.
6.16 General purpose timers
The Timer/Counter is designed to count cycles of the peripheral clock (PCLK) or an
externally supplied clock 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.
The LPC2220 can count external events on one of the capture inputs if the minimum
external pulse is equal or longer than a period of the PCLK. In this configuration, unused
capture lines can be selected as regular timer capture inputs.

– 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/counter 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 prescaler.
Selectable time period from (Tcy(PCLK) × 256 × 4) to (Tcy(PCLK) × 232 × 4) in multiples of
Tcy(PCLK) × 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.

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 LPC2210/2220. 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 and up to 50 MHz with
the external oscillator. 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 60/75 MHz (LPC2210/2220) 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. The PLL settling time is 100 µs.
6.20.3 Reset and wake-up timer
Reset has two sources on the LPC2210/2220: 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

LPC2210/2220
NXP Semiconductors
16/32-bit ARM microcontrollers with external memory interface
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 LPC2210/2220 include 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 0x0000 0000. 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 LPC2210/2220 support 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 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 APB bus
The APB divider determines the relationship between the processor clock (CCLK) and the
clock used by peripheral devices (PCLK). The APB divider serves two purposes. The first
is to provide peripherals with the desired PCLK via APB bus so that they can operate at
the speed chosen for the ARM processor. In order to achieve this, the APB bus may be
slowed down to 1⁄2 to 1⁄4 of the processor clock rate. Because the APB bus must work

LPC2210/2220
NXP Semiconductors
16/32-bit ARM microcontrollers with external memory interface
properly at power-up (and its timing cannot be altered if it does not work since the APB
divider control registers reside on the APB bus), the default condition at reset is for the
APB bus to run at 1⁄4 of the processor clock rate. The second purpose of the APB divider
is to allow power savings when an application does not require any peripherals to run at
the full processor rate. Because the APB divider is connected to the PLL output, the PLL
remains active (if it was running) during Idle mode.
6.21 Emulation and debugging
The LPC2210/2220 support 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 EmbeddedICE
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 converter. EmbeddedICE protocol converter 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 LPC2210/2220 have 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 (ETM) 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 cannot be traced
because of this restriction.

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 Debug

the on-chip flash memory.
