1. General description

The LPC2109/2119/2129 are based on a 16/32-bit ARM7TDMI-S CPU with real-time

emulation and embedded trace support, together with 64/128/256 kB of embedded

high-speed ﬂash memory. A 128-bit wide memory interface and a unique accelerator

architecture enable 32-bit code execution at maximum clock rate. For critical code size

applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with

minimal performance penalty.

With their compact 64-pin package, low power consumption, various 32-bit timers,

4-channel 10-bit ADC, two advanced CAN channels, PWM channels and 46 fast GPIO

lines with up to nine external interrupt pins these microcontrollers are particularly suitable

for automotive and industrial control applications, as well as medical systems and

fault-tolerant maintenance buses. With a wide range of additional serial communications

interfaces, they are also suited for communication gateways and protocol converters as

well as many other general-purpose applications.

Remark: Throughout the data sheet, the term LPC2109/2119/2129 will apply to devices

with and without the /00 or /01 sufﬁxes. The /00 or the /01 sufﬁx will be used to

differentiate from other devices only when necessary.

2. Features

2.1 Key features brought by LPC2109/2119/2129/01 devices

n Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original device.

They also allow for a port pin to be read at any time regardless of its function.

n Dedicated result registers for ADC(s) reduce interrupt overhead. The ADC pads are

5 V tolerant when conﬁgured for digital I/O function(s).

n UART0/1 include fractional baud rate generator, auto-bauding capabilities and

handshake ﬂow-control fully implemented in hardware.

n Buffered SSP serial controller supporting SPI, 4-wire SSI, and Microwire formats.

n SPI programmable data length and master mode enhancement.

n Diversiﬁed Code Read Protection (CRP) enables different security levels to be

implemented. This feature is available in LPC2109/2119/2129/00 devices as well.

n General purpose timers can operate as external event counters.

2.2 Key features common for all devices

n 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.

n 8/16 kB on-chip static RAM.

LPC2109/2119/2129

Single-chip 16/32-bit microcontrollers

n 64/128/256 kB on-chip ﬂash program memory. 128-bit wide interface/accelerator

enables high speed 60 MHz operation.

n In-System Programming (ISP) and In-Application Programming (IAP) via on-chip

bootloader software. Flash programming takes 1 ms per 512 B line. Single sector or

full chip erase takes 400 ms.

n EmbeddedICE-RT interface enables breakpoints and watch points. Interrupt service

routines can continue to execute while the foreground task is debugged with the

on-chip RealMonitor software.

n Embedded Trace Macrocell (ETM) enables non-intrusive high speed real-time tracing

of instruction execution.

n Two interconnected CAN interfaces (one for LPC2109) with advanced acceptance

ﬁlters.

n Four-channel 10-bit A/D converter with conversion time as low as 2.44 µs.

n Multiple serial interfaces including two UARTs (16C550), Fast I

C-bus (400 kbit/s) and

two SPIs.

n 60 MHz maximum CPU clock available from programmable on-chip Phase-Locked

Loop with settling time of 100 µs.

n Vectored Interrupt Controller with conﬁgurable priorities and vector addresses.

n Two 32-bit timers (with four capture and four compare channels), PWM unit (six

outputs), Real-Time Clock (RTC) and watchdog.

n Up to forty-six 5 V tolerant general purpose I/O pins. Up to nine edge or level sensitive

external interrupt pins available.

n On-chip crystal oscillator with an operating range of 1 MHz to 30 MHz.

n Two low power modes, Idle and Power-down.

n Processor wake-up from Power-down mode via external interrupt.

n Individual enable/disable of peripheral functions for power optimization.

n Dual power supply:

u CPU operating voltage range of 1.65 V to 1.95 V (1.8 V ± 0.15 V).

u I/O power supply range of 3.0 V to 3.6 V (3.3 V ± 10 %) with 5 V tolerant I/O pads.
