Preliminary data sheet
1. General description
The LPC3220/30/40/50 embedded microcontrollers were designed for low power, high
performance applications. NXP achieved their performance goals using a 90 nanometer
process to implement an ARM926EJ-S CPU core with a vector floating point co-processor
and a large set of standard peripherals including USB On-The-Go. The
LPC3220/30/40/50 operates at CPU frequencies of up to 266 MHz.
The NXP implementation uses a ARM926EJ-S CPU core with a Harvard architecture,
5-stage pipeline, and an integral Memory Management Unit (MMU). The MMU provides
the virtual memory capabilities needed to support the multi-programming demands of
modern operating systems. The ARM926EJ-S also has a hardware based set of DSP
instruction extensions, which includes single cycle MAC operations, and hardware based
native Jazelle Java Byte-code execution. The NXP implementation has a 32 kB instruction
cache and a 32 kB data cache.
For low power consumption, the LPC3220/30/40/50 takes advantage of NXP’s advanced
technology development to optimize intrinsic power and uses software controlled
architectural enhancements to optimize application based power management.
The LPC3220/30/40/50 also includes 256 kB of on-chip static RAM, a NAND flash
interface, an Ethernet MAC, an LCD controller that supports STN and TFT panels, and an
external bus interface that supports SDR and DDR SDRAM as well as static devices. In
addition, the LPC3220/30/40/50 includes a USB 2.0 full-speed interface, seven UARTs,
two I2C-bus interfaces, two SPI/SSP ports, two I2S-bus interfaces, two single output
PWMs, a motor control PWM, six general purpose timers with capture inputs and
compare outputs, a Secure Digital (SD) interface, and a 10-bit Analog-to-Digital Converter
(ADC) with a touch screen sense option.

n External memory controller for DDR and SDR SDRAM as well as for static devices.
n Two NAND flash controllers: One for single-level NAND flash devices and the other for
multi-level NAND flash devices.
n Master Interrupt Controller (MIC) and two Slave Interrupt Controllers (SIC), supporting
74 interrupt sources.
n Eight channel General Purpose DMA (GPDMA) controller on the AHB that can be
used with the SD card port, the high-speed UARTs, I2S-bus interfaces, and SPI
interfaces, as well as memory-to-memory transfers.
n Serial interfaces:
u 10/100 Ethernet MAC with dedicated DMA Controller.
u USB interface supporting either device, host (OHCI compliant), or On-The-Go
(OTG) with an integral DMA controller and dedicated PLL to generate the required
48 MHz USB clock.
u Four standard UARTs with fractional baud rate generation and 64 byte FIFOs. One
of the standard UART’s supports IrDA.
u Three additional high-speed UARTs intended for on-board communications that
support baud rates up to 921 600 when using a 13 MHz main oscillator. All
high-speed UARTs provide 64 byte FIFOs.
u Two SPI controllers.
u Two SSP controllers.
u Two I2C-bus interfaces with standard open-drain pins. The I2C-bus interfaces
support single master, slave, and multi-master I2C-bus configurations.
u Two I2S-bus interfaces, each with separate input and output channels. Each
channel can be operated independently on three pins, or both input and output
channels can be used with only four pins and a shared clock.
n Additional peripherals:
u LCD controller supporting both STN and TFT panels, with dedicated DMA
controller. Programmable display resolution up to 1024 × 768.
u Secure Digital (SD) memory card interface, which conforms to the SD Memory
Card Specification Version 1.01.
u General Purpose (GP) input, output, and I/O pins. Includes 12 GP input pins, 24
GP output pins, and 51 GP I/O pins.
u 10 bit, 400 kHz Analog-to-Digital Converter (ADC) with input multiplexing from
three pins. Optionally, the ADC can operate as a touch screen controller.
u Real-Time Clock (RTC) with separate power pin and dedicated 32 kHz oscillator.
NXP implemented the RTC in an independent on-chip power domain so it can
remain active while the rest of the chip is not powered. The RTC also includes a
32 byte scratch pad memory.
u 32-bit general purpose high-speed timer with a 16-bit pre-scaler. This timer
includes one external capture input pin and a capture connection to the RTC clock.
Interrupts may be generated using three match registers.
u Six enhanced timer/counters which are architecturally identical except for the
peripheral base address. Two capture inputs and two match outputs are pinned out
to four timers. Timer 1 brings out a third match output, timers 2 and 3 bring out all
four match outputs, timer 4 has one match output, and timer 5 has no inputs or
outputs.
u 32-bit millisecond timer driven from the RTC clock. This timer can generate
interrupts using two match registers.

7. Functional description
7.1 CPU and subsystems
7.1.1 CPU
NXP created the LPC3220/30/40/50 using an ARM926EJ-S CPU core that includes a
Harvard architecture and a 5-stage pipeline. To this ARM core, NXP implemented a 32 kB
instruction cache, a 32 kB data cache and a Vector Floating Point coprocessor. The
ARM926EJ-S core also has an integral Memory Management Unit (MMU) to provide the
virtual memory capabilities required to support the multi-programming demands of
modern operating systems. The basic ARM926EJ-S core V5TE instruction set includes
DSP instruction extensions for native Jazelle Java Byte-code execution in hardware. The
LPC3220/30/40/50 operates at CPU frequencies up to 266 MHz.
7.1.2 Vector Floating Point (VFP) coprocessor
The LPC3220/30/40/50 includes a VFP co-processor providing full support for
single-precision and double-precision add, subtract, multiply, divide, and
multiply-accumulate operations at CPU clock speeds. It is compliant with the IEEE 754
standard for binary Floating-Point Arithmetic. This hardware floating point capability
makes the microcontroller suitable for advanced motor control and DSP applications. The
VFP has 3 separate pipelines for Floating-point MAC operations, divide or square root
operations, and Load/Store operations. These pipelines operate in parallel and can
complete execution out of order. All single-precision instructions execute in one cycle,
except the divide and square root instructions. All double-precision multiply and
multiply-accumulate instructions take two cycles. The VFP also provides format
conversions between floating-point and integer word formats.
7.1.3 Emulation and debugging
The LPC3220/30/40/50 supports emulation and debugging via a dedicated JTAG serial
port. An Embedded Trace Buffer allows tracing program execution. The dedicated JTAG
port allows debugging of all chip features without impact to any pins that may be used in
the application.
7.1.3.1
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
Embedded ICE protocol converter. The Embedded ICE 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 (DCC) 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 entering the
debug state.

NXP Semiconductors
16/32-bit ARM microcontrollers
7.1.3.2
Embedded trace buffer
The Embedded Trace Module (ETM) is connected directly to the ARM core. It compresses
the trace information and exports it through a narrow trace port. An internal Embedded
Trace Buffer (ETB) of 2048 × 24 bits captures the trace information under software
debugger control. Data from the ETB is recovered by the debug software through the
JTAG port.
The trace contains information about when the ARM core switches between states.
Instruction 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. For data accesses either data or address or both can be
traced.
7.2 AHB matrix
The LPC3220/30/40/50 has a multi-layer AHB matrix for inter-block communication. AHB
is an ARM defined high-speed bus, which is part of the ARM bus architecture. AHB is a
high-bandwidth low-latency bus that supports multi-master arbitration and a bus
grant/request mechanism. For systems that have only one (CPU), or two (CPU and DMA)
bus masters a simple AHB works well. However, if a system requires multiple bus masters
and the CPU needs access to external memory, a single AHB bus can cause a bottleneck.
To increase performance, the LPC3220/30/40/50 uses an expanded AHB architecture
known as Multi-layer AHB. A Multi-layer AHB replaces the request/grant and arbitration
mechanism used in a simple AHB with an interconnect matrix that moves arbitration out
toward the slave devices. Thus, if a CPU and a DMA controller want access to the same
memory, the interconnect matrix arbitrates between the two when granting access to the
memory. This advanced architecture allows simultaneous access by bus masters to
different resources with an increase in arbitration complexity. In this architectural
implementation, removing guaranteed central arbitration and allowing more than one bus
master to be active at the same time provides better overall microcontroller performance.
In the LPC3220/30/40/50, the multi-Layer AHB system has a separate bus for each of
seven AHB Masters:
•
•
•
•
•
•
•
CPU data bus
CPU instruction bus
General purpose DMA Master 0
General purpose DMA Master 1
Ethernet controller
USB controller
LCD controller
There are no arbitration delays unless two masters attempt to access the same slave at
the same time.

16/32-bit ARM microcontrollers
7.2.1 APB
Many peripheral functions are accessed by on-chip APBs that are attached to the higher
speed AHB. The APB performs reads and writes to peripheral registers in three peripheral
clocks.
7.2.2 FAB
Some peripherals are placed on a special bus called FAB that allows faster CPU access
to those peripheral functions. A write access to FAB peripherals takes a single AHB clock
and a read access to FAB peripherals takes two AHB clocks.
7.3 Physical memory map
The physical memory map incorporates several distinct regions, as shown in Figure 3.
When an application is running, the CPU interrupt vectors are re-mapped to allow them to
reside in on-chip SRAM (IRAM).

7.4 Internal memory
7.4.1 On-chip ROM
The built-in 16 kB ROM contains a program which runs a boot procedure to load code
from one of four external sources, UART5, SSP0 (SPI mode), EMC Static CS0 memory, or
NAND FLASH.
After reset, execution always begins from the internal ROM. The bootstrap software first
reads the SERVICE input (GPI_1). If SERVICE is LOW, the bootstrap starts a service boot
and can download a program over serial link UART5 to IRAM and transfer execution to the
downloaded code.
If the SERVICE pin is HIGH, the bootstrap routine jumps to normal boot. The normal boot
process first tests SPI memory for boot information if present it uploads the boot code and
transfers execution to the uploaded software. If the SPI is not present or no software is
loaded, the bootloader will test the EMC Static CS0 memory for the presence of boot code
and if present boots from static memory, If this test fails the boot loader will test external
NAND flash for boot code and boot if code is present.
The boot loader consumes no user memory space because it is in ROM.
7.4.2 On-chip SRAM
On-chip SRAM may be used for code and/or data storage. The SRAM may be accessed
as 8, 16, or 32 bit memory. The LPC3220/30/40/50 provides 256 kB of internal SRAM.
7.5 External memory interfaces
The LPC3220/30/40/50 includes three external memory interfaces, NAND Flash
controllers, Secure Digital Memory Controller, and an external memory controller for
SDRAM, DDR SDRAM, and Static Memory devices.
7.5.1 NAND flash controllers
The LPC3220/30/40/50 includes two NAND flash controllers, one for multi-level cell NAND
flash devices and one for single-level cell NAND flash devices. The two NAND flash
controllers use the same pins to interface to external NAND flash devices, so only one
interface is active at a time.
7.5.1.1
Multi-Level Cell (MLC) NAND flash controller
The MLC NAND flash controller interfaces to either multi-level or single-level NAND flash
devices. An external NAND flash device is used to allow the bootloader to automatically
load a portion of the application code into internal SRAM for execution following reset.
The MLC NAND flash controller supports small (528 byte) and large (2114 byte) pages.
Programmable NAND timing parameters allow support for a variety of NAND flash
devices. A built-in Reed-Solomon encoder/decoder provides error detection and
correction capability. A 528 byte data buffer reduces the need for CPU supervision during
loading. The MLC NAND flash controller also provides DMA support.

for ECC (Error Checking and Correction) is included for the main data area. Software can
correct a single bit error.
7.5.2 SD card controller
The SD interface allows access to external SD memory cards. The SD card interface
conforms to the SD Memory Card Specification Version 1.01.
7.5.2.1
Features
• 1-bit and 4-bit data line interface support.
• DMA is supported through the system DMA controller.
• Provides all functions specific to the SD memory card. These include the clock
generation unit, power management control, command and data transfer.
7.5.3 External memory controller
The LPC3220/30/40/50 includes a memory controller that supports data bus SDRAM,

7.6 AHB master peripherals
The LPC3220/30/40/50 implements four AHB master peripherals, which include a
General Purpose Direct Memory Access (GPDMA) controller, a 10/100 Ethernet Media
Access Controller (MAC), a Universal Serial Bus (USB) controller, and an LCD controller.
Each of these four peripherals contain an integral DMA controller optimized to support the
performance demands of the peripheral.
7.6.1 General Purpose DMA (GPDMA) controller
The GPDMA controller allows peripheral-to memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream
provides unidirectional serial DMA transfers for a single source and destination. For
example, a bidirectional port requires one stream for transmit and one for receive. The
source and destination areas can each be either a memory region or a peripheral, and
can be accessed through the same AHB master, or one area by each master. The DMA
controller supports the following peripheral device transfers.
•
•
•
•
•
•
Secure Digital (SD) Memory interface
High-speed UARTs
I2S0 and I2S1 ports
SPI1 and SPI2 interfaces
SSP0 and SSP1 interfaces
Memory
The DMA controls eight DMA channels with hardware prioritization. The DMA controller
interfaces to the system via two AHB bus masters, each with a full 32-bit data bus width.
DMA operations may be set up for 8-bit, 16-bit, and 32-bit data widths, and can be either
big-endian or little-endian. Incrementing or non-incrementing addressing for source and
destination are supported, as well as programmable DMA burst size. Scatter or gather
DMA is supported through the use of linked lists. This means that the source and
destination areas do not have to occupy contiguous areas of memory.
7.6.2 Ethernet MAC
The Ethernet block contains a full featured 10 Mbit/s or 100 Mbit/s Ethernet MAC
designed to provide optimized performance through the use of DMA hardware
acceleration. Features include a generous suite of control registers, half or full duplex
operation, flow control, control frames, hardware acceleration for transmit retry, receive

7.7 System functions
To enhance the performance of the LPC3220/30/40/50 incorporates the following system
functions, an Interrupt Controller (INTC), a watchdog timer, a millisecond timer, and
several power control features. These functions are described in the following sections
7.7.1 Interrupt controller
The interrupt controller is comprised of three basic interrupt controller blocks, supporting a
total of 73 interrupt sources. Each interrupt source can be individually enabled/disabled
and configured for high or low level triggering, or rising or falling edge triggering. Each
interrupt may also be steered to either the FIQ or IRQ input of the ARM9. Raw interrupt
status and masked interrupt status registers allow versatile condition evaluation. In
addition to peripheral functions, each of the six general purpose input/output pins and
12 of the 22 general purpose input pins are connected directly to the interrupt controller.
7.7.2 Watchdog timer
The watchdog timer block is clocked by the main peripheral clock, which clocks a 32-bit
counter. A match register is compared to the Timer. When configured for watchdog
functionality, a match drives the match output low. The match output is gated with an
enable signal that gives the opportunity to generate two type of reset signal: one that only
resets chip internally, and another that goes through a programmable pulse generator
before it goes to the external pin RESOUT and to the internal chip reset.
7.7.2.1
Features
•
•
•
•
•
•
Programmable 32-bit timer.
Internally resets the device if not periodically reloaded.
Flag to indicate that a watchdog reset has occurred.
Programmable watchdog pulse output on RESOUT pin.
Can be used as a standard timer if watchdog is not used.
Pause control to stop counting when core is in debug state.
7.7.3 Millisecond timer
The millisecond timer is clocked by 32 kHz RTC clock, so a prescaler is not needed to
obtain a lower count rate.
The millisecond timer includes three match registers that are compared to the
Timer/Counter value. A match can generate an interrupt and the cause the Timer/Counter
either continue to run, stop, or be reset.
7.7.3.1
Features
• 32-bit Timer/Counter, running from the 32 kHz RTC clock.
• Counter or Timer operation.
• Three 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.
• Pause control to stop counting when core is in debug state.

7.7.4 Clocking and power control features
7.7.4.1
Clocking
Clocking in the LPC3220/30/40/50 is designed to be versatile, so that system and
peripheral requirements may be met, while allowing optimization of power consumption.
Clocks to most functions may be turned off if not needed and some peripherals do this
automatically.
The LPC3220/30/40/50 supports three operational modes, two of which are specifically
designed to reduce power consumption. The modes are: Run mode, Direct run mode, and
Stop mode.These three operational modes give control over processing speed and power
consumption. In addition, clock rates to different functional blocks may be changed by
switching clock sources, changing PLL values, or altering clock divider configurations.
This allows a trade-off of power versus processing speed based on application
requirements.
7.7.4.2
Crystal oscillator
The main oscillator is the basis for the clocks most chip functions use by default.
Optionally, many functions can be clocked instead by the output of a PLL (with a fixed
397x rate multiplication) which runs from the RTC oscillator. In this mode, the main
oscillator may be turned off unless the USB interface is enabled. If a SYSCLK frequency
other than 13 MHz is required in the application, or if the USB block is not used, the main
oscillator may be used with a frequency of between 1 MHz and 20 MHz.
7.7.4.3
PLLs
The LPC3220/30/40/50 includes three PLLs: The 397x PLL allows boosting the RTC
frequency to 13.008896 MHz for use as the primary system clock. The USB PLL provides
the 48 MHz clock required by the USB block, and the HCLK PLL provides the basis for the
CPU clock, the AHB bus clock, and the main peripheral clock.
The 397x PLL multiplies the 32768 Hz RTC clock by 397 to obtain a 13.008896 MHz
clock. The 397x PLL is designed for low power operation and low jitter. This PLL requires
an external RC loop filter for proper operation.
The HCLK PLL accepts an input clock from either the main oscillator or the output of the
397x PLL. The USB PLL only accepts an input clock from the main oscillator.The USB
input clock runs through a divide-by-N pre-divider before entering the USB PLL.
The input to the HCLK and USB PLLs may initially be divided down by a pre-divider value
‘N’, which may have the values 1, 2, 3, or 4. This pre-divider can allow a greater number of
possibilities for the output frequency. Following the PLL input divider is the PLL multiplier.
This can multiply the pre-divider output by a value ‘M’, in the range of 1 through 256. The
resulting frequency must be in the range of 156 MHz to 320 MHz. The multiplier works by
dividing the output of a Current Controlled Oscillator (CCO) by the value of M, then using
a phase detector to compare the divided CCO output to the pre-divider output. The error
value is used to adjust the CCO frequency.
At the PLL output, there is a post-divider that can be used to bring the CCO frequency
down to the desired PLL output frequency. The post-divider value can divide the CCO
output by 1, 2, 4, 8, or 16. The post-divider can also be bypassed, allowing the PLL CCO

output to be used directly. The maximum PLL output frequency supported by the CPU is
266 MHz. The only output frequency supported by the USB PLL is 48 MHz, and the clock
has strict requirements for nominal frequency (500 ppm) and jitter (500 ps).
7.7.4.4
Power control modes
The LPC3220/30/40/50 supports three operational modes, two of which are specifically
designed to reduce power consumption. The modes are: Run mode, Direct Run mode,
and Stop mode.
Run mode is the normal operating mode for applications that require the CPU, AHB bus,
or any peripheral function other than the USB block to run faster than the main oscillator
frequency. In Run mode, the CPU can run at up to 266 MHz and the AHB bus can run at
up to 133 MHz.
Direct Run mode allows reducing the CPU and AHB bus rates in order to save power.
Direct Run mode can also be the normal operating mode for applications that do not
require the CPU, AHB bus, or any peripheral function other than the USB block to run
faster than the main oscillator frequency. Direct Run mode is the default mode following
chip reset.
Stop mode causes all CPU and AHB operation to cease, and stops clocks to peripherals
other than the USB block.
7.7.4.5
Reset
Reset is accomplished by an active LOW signal on the RESET input pin. A reset pulse
with a minimum width of 10 main oscillator clocks after the oscillator is stable is required to
guarantee a valid chip reset. At power-up, 10 milliseconds should be allowed for the
oscillator to start up and stabilize after VDD reaches operational voltage. An internal reset
with a minimum duration of 10 clock pulses will also be applied if the watchdog timer
generates an internal device reset.
The RESET pin is located in the RTC power domain. This means that the RTC power
must be present for an external reset to have any effect. The RTC power domain
nominally runs from 1.2 V, but the RESET pin can be driven as high as 1.95 V.
7.8
Communication peripheral interfaces
In addition to the Ethernet MAC and USB interfaces there are many more serial
communication peripheral interfaces available on the LPC3220/30/40/50. Here is a list of
the serial communication interfaces:
•
•
•
•
•
Seven UARTs; four standard UARTs and three high-speed UARTs
Two SPI serial I/O controllers
Two SSP serial I/O controllers
Two I2C serial I/O controllers
Two I2S audio controllers

The LPC3220/30/40/50 contains two SSP controllers. The SSP controller is 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. The SSP 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.

16/32-bit ARM microcontrollers
There is a separate slave transmit FIFO. The slave transmit FIFO (TXS) and its level are
only available when the controller is configured as a Master/Slave device and is operating
in a multi-master environment. Separate TX FIFOs are needed in a multi-master because
a controller might have a message queued for transmission when an external master
addresses it to be come a slave-transmitter, a second source of data is needed.
Note that the I2C clock must be enabled in the I2CCLK_CTRL register before using the
I2C. The I2C clock can be disabled between communications, if used as a single master
I2C-bus interface, software has full control of when I2C communication is taking place on
the bus.
7.8.4.1
Features
• The two I2C-bus blocks are standard I2C-bus compliant interfaces that may be used in
Single-master, Multi-master or Slave modes.
• Programmable clock to allow adjustment of I2C-bus transfer rates.
• Bidirectional data transfer.
• 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.
7.8.5 I2S-bus audio controller
The I2S-bus provides a standard communication interface for digital audio applications
The I2S-bus specification defines a 3-wire serial bus using one data line, one clock line,
and one word select signal. Each I2S connection can act as a master or a slave. The
master connection determines the frequency of the clock line and all other slaves are
driven by this clock source. The two I2S-bus interfaces on the LPC3220/30/40/50 provides
a separate transmit and receive channel, providing a total of two transmit channels and
two receive channels. Each I2S channel supports monaural or stereo formatted data.
7.8.5.1
Features
• The interface has separate input/output channels each of which can operate in master
or slave mode.
• Capable of handling 8-bit, 16-bit, and 32-bit word sizes.
• Mono and stereo audio data supported.
• Supports standard sampling frequencies (8 kHz, 11.025 kHz, 16 kHz, 22.05 kHz,
32 kHz, 44.1 kHz, 48 kHz, 96 kHz).
• Word select period can be configured in master mode (separately for I2S input and
output).
• Two 8 word FIFO data buffers are provided, one for transmit and one for receive.

7.9 Other peripherals
In addition to the communication peripherals there are many general purpose peripherals
available in the LPC3220/30/40/50. Here is a list of the general purpose peripherals.
•
•
•
•
•
•
•
•
GPI/O
Keyboard scanner
Touch screen controller and 10-bit Analog-to-Digital-Converter
Real-time clock
High-speed timer
Four general purpose 32-bit timer/external event counters
Two simple PWMs
One motor control PWM
A short functional description of each of these peripherals is provided in the following
sections.
7.9.1 General purpose parallel I/O
Some device pins that are not dedicated to a specific peripheral function have been
designed to be general purpose inputs, outputs, or input/outputs. Also, some pins may be
configured either as a specific peripheral function or a general purpose input, output, or
input/output. A total of 51 pins can potentially be used as general purpose input/outputs,
24 as general purpose outputs, and 22 as general purpose inputs.
GPIO pins may be dynamically configured as inputs or outputs. Separate registers allow
setting or clearing any number of GPIO and GPO outputs controlled by that register
simultaneously. The value of the output register for standard GPIOs and GPO pins may be
read back, as well as the current actual state of the port pins.
In addition to GPIO pins on port 0, port 1, and port 2, there are 22 GPI, 24 GPO, and
six GPIO pins. When the SDRAM bus is configured for 16 data bits, 13 of the remaining
SDRAM data pins may be used as GPIOs.
7.9.1.1
Features
• Bit-level set and clear registers allow a single instruction set or clear of any number of
bits in one port.
• A single register selects direction for pins that support both input and output modes.
• Direction control of individual bits.
• For input/output pins, both the programmed output state and the actual pin state can
be read.
• There are a total of 12 general purpose inputs, 24 general purpose outputs, and six
general purpose input/outputs.
• Additionally, 13 SDRAM data lines may be used as GPIOs if a 16-bit SDRAM
interface is used (rather than a 32-bit interface).

7.9.2 Keyboard scanner
The keyboard scanner function can automatically scan a keyboard of up to 64 keys in an
8 × 8 matrix. In operation, the keyboard scanner’s internal state machine will normally be
in an idle state, with all KEY_ROWn pins set high, waiting for a change in the column
inputs to indicate that one or more keys have been pressed.
When a keypress is detected, the matrix is scanned by setting one output pin high at a
time and reading the column inputs. After de-bouncing, the keypad state is stored and an
interrupt is generated. The keypad is then continuously scanned waiting for ‘extra key
pressed’ or ‘key released’. Any new keypad state is scanned and stored into the matrix
registers followed by a new interrupt request to the interrupt controller. It is possible to
detect and separate up to 64 multiple keys pressed.
7.9.2.1
Features
• Supports up to 64 keys in 8 × 8 matrix.
• Programmable de-bounce period.
• A key press can wake up the CPU from Stop mode.
7.9.3 Touch screen controller and 10-bit ADC
The LPC3220/30/40/50 microcontrollers includes Touch Screen Controller (TSC)
hardware, which automatically measures and determines the X and Y coordinates where
a touch screen is pressed. In addition, the TSC can measure an analog input signal on the
AUX_IN pin.
Optionally, the TSC can operate as an Analog-to-Digital Converter (ADC). The ADC
supports three channels and uses 10-bit successive approximation to produce results
with a resolution of 10 bits in 11 clock cycles.
The analog portion of the ADC has its own power supply to enhance the low noise
characteristics of the converter. This voltage is only supplied internally when the core has
voltage. However, the ADC block is not affected by any difference in ramp-up time for
VDD_AD and VDD_CORE voltage supplies.
7.9.3.1
Features
•
•
•
•
•
Measurement range of 0 V to VDD_AD (nominally 3.3 V).
Low noise ADC.
10-bit resolution.
Three input channels.
Uses 32 kHz RTC clock or peripheral clock.
7.9.4 Real-Time Clock (RTC) and battery RAM
The RTC runs at 32768 Hz using a very low power oscillator. The RTC counts seconds
and can generate alarm interrupts that can wake up the device from Stop mode. The RTC
clock can also clock the 397x PLL, the Millisecond Timer, the ADC, the Keyboard Scanner
and the PWMs. The RTC up-counter value represents a number of seconds elapsed since
second 0, which is an application determined time. The RTC counter will reach maximum
value after about 136 years. The RTC down-counter is initiated with all ones.

16/32-bit ARM microcontrollers
Two 32-bit match registers are readable and writable by the processor. A match will result
in an interrupt provided that the interrupt is enabled. The ONSW output pin can also be
triggered by a match event, and cause an external power supply to turn on all of the
operating voltages, as a way to startup after power has been removed.
The RTC block is implemented in a separate voltage domain. The block is supplied via a
separate supply pin from a battery or other power source.
The RTC block also contains 32 words (128 Bytes) of very low voltage SRAM. This SRAM
is able to hold its contents down to the minimum RTC operating voltage.
7.9.4.1
Features
•
•
•
•
•
Measures the passage of time in seconds.
32-bit up and down seconds counters.
Ultra-low power design to support battery powered systems.
Dedicated 32 kHz oscillator.
An output pin is included to assist in waking up when the chip has had power removed
to all functions except the RTC.
• Two 32-bit match registers with interrupt option.
• 32 words (128 Bytes) of very low voltage SRAM.
• The RTC and battery RAM power have an independent power domain and dedicated
supply pins, which can be powered from a battery or power supply.
Remark: The LPC3220/30/40/50 will run at voltages down to 0.9 V at frequencies below
14 MHz. However, the ARM core cannot access the RTC registers and battery RAM when
the core supply voltage is at 0.9 V and the RTC supply is at 1.2 V.
7.9.5 Enhanced 32-bit timers/external event counters
The LPC3220/30/40/50 includes six 32-bit Timer/Counters. The Timer/Counter is
designed to count cycles of the system derived clock or an externally-supplied clock. It
can optionally generate interrupts or perform other actions at specified timer values,
based on four match registers. The Timer/Counter also includes four capture inputs to trap
the timer value when an input signal transitions, optionally generating an interrupt.
7.9.5.1
Features
• A 32-bit Timer/Counter with a programmable 32-bit pre-scaler.
• Counter or Timer operation.
• Up to 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
• Up to four external outputs corresponding to match registers, with the following
capabilities:

7.9.6 High-speed timer
The high-speed timer block is clocked by the main peripheral clock. The clock is first
divided down in a 16-bit programmable pre-scale counter which clocks a 32-bit
timer/counter.
The high-speed timer includes three match registers that are compared to the
timer/counter value. A match can generate an interrupt and cause the timer/counter to
either continue to run, stop, or be reset. The high-speed timer also includes two capture
registers that can take a snapshot of the timer/counter value when an input signal
transitions. A capture event may also generate an interrupt.
7.9.6.1
Features

– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Pause control to stop counting when core is in debug state.
7.9.7 Pulse Width Modulators (PWMs)
The LPC3220/30/40/50 provides two simple PWMs. They are clocked separately by either
the main peripheral clock or the 32 kHz RTC clock. Both PWMs have a duty cycle
programmable in 255 steps.

8. Basic architecture
The LPC3220/30/40/50 is a general purpose ARM926EJ-S 32-bit microprocessor with a
32 kB instruction cache and a 32 kB data cache. The microcontroller offers high
performance and very low power consumption. The ARM architecture is based on RISC
principles, which results in the instruction set and related decode mechanism being much
simpler than equivalent micro programmed CISCs. This simplicity results in a high
instruction throughput and impressive real-time interrupt response from a small and
cost-effective processor core.
The ARM926EJ-S core employs a 5-stage pipeline so processing and memory system
accesses can occur continuously. At any one point in time, several operations are in
progress: subsequent instruction fetch, next instruction decode, instruction execution,
memory access, and write-back. The combination of architectural enhancements gives
the ARM9 about 30 % better performance than an ARM7 running at the same clock rate:
• Approximately 1.3 clocks per instruction for the ARM926 compared to 1.9 clocks per
instruction for ARM7TDMI.
• Approximately 1.1 Dhrystone MIPS/MHz for the ARM926 compared to 0.9 Dhrystone
MIPS/MHz for ARM7TDMI.
The ARM926EJ-S processor also employs an operational state 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 state is the use of a super-reduced instruction set.
Essentially, the ARM926EJ-S processor core has two instruction sets:
1. The standard 32-bit ARM set
2. The 16-bit Thumb set
The Thumb set’s smaller 16-bit instruction length allows it to approach twice the density of
standard ARM code while retaining many of ARM’s 32-bit performance advantage over a
traditional 16-bit processor using 16-bit registers. This is possible because Thumb code
operates using the same 32-bit register set as ARM code. Thumb code size is up to 65 %
smaller than ARM code size, and 160 % of the performance of an equivalent ARM
processor connected to a 16-bit memory system. Additionally, the ARM926EJ-S core
includes enhanced DSP instructions and multiplier, as well as an enhanced 32-bit MAC
block.

[10] The applicable VDD voltage for the pin must be present.
[11] 3-state outputs go into 3-state mode when VDD(3V0) is grounded.
[12] Accounts for 100 mV voltage drop in all supply lines.
[13] Allowed as long as the current limit does not exceed the maximum current allowed by the device.
10.1 Power supply sequencing
The LPC32x0 has no power sequencing requirements, that is, VDD(1V2), VDD(EMC), VDD(IO),
and VDDA(3V3) can be switched on or off independent of each other. An internal circuit
takes care that the system correctly powers up in the absence of core power. During IO
power-up this circuit takes care that the system is powered in a defined mode. The same
is valid for core power-down.

[2]
The ADC is monotonic; there are no missing codes.
[3]
The differential linearity error (ED) is the difference between the actual step width and the ideal step width. See Figure 4.
[4]
The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and the ideal transfer curve after
appropriate adjustment of gain and offset errors. See Figure 4.
[5]
The offset error (EO) 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.
[6]
The gain error (EG) 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.
[7]
The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated ADC
and the ideal transfer curve. See Figure 4.
