LPC2119/LPC2129
Single-chip 16/32-bit microcontrollers; 128/256 kB ISP/IAP
Flash with 10-bit ADC and CAN
Rev. 03 — 22 December 2004 Product data
1. General description
The LPC2119/LPC2129 are based on a 16/32 bit ARM7TDMI-S™ CPU with real-time
emulation and embedded trace support, together with 128/256 kilobytes (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, 2 advanced CAN channels, PWM channels and 46 GPIO lines
with up to 9 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.
2. Features
2.1 Key features
■ 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.
■ 16 kB on-chip Static RAM.
■ 128/256 kB on-chip Flash Program Memory. 128-bit wide interface/accelerator
enables high speed 60 MHz operation.
■ In-System Programming (ISP) and In-Application Programming (IAP) via on-chip
boot-loader software. Flash programming takes 1 ms per 512 byte line. Single
sector or full chip erase takes 400 ms.
■ 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.
■ Embedded Trace Macrocell enables non-intrusive high speed real-time tracing of
instruction execution.
■ Two interconnected CAN interfaces with advanced acceptance filters.
■ Four channel 10-bit A/D converter with conversion time as low as 2.44 µs.
■ Multiple serial interfaces including two UARTs (16C550), Fast I
2
C (400 kbits/s)
and two SPIs
■ 60 MHz maximum CPU clock available from programmable on-chip
Phase-Locked Loop with settling time of 100 µs.
■ Vectored Interrupt Controller with configurable priorities and vector addresses.
■ Two 32-bit timers (with four capture and four compare channels), PWM unit (six
outputs), Real Time Clock and Watchdog.
