Product data

1. General description

The LPC2114/LPC2124 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, PWM channels and 46 GPIO lines with up to 9 external

interrupt pins these microcontrollers are particularly suitable for industrial control,

medical systems, access control and point-of-sale. With a wide range of serial

communications interfaces, they are also very well suited for communication

gateways, protocol converters and embedded soft modems as well as many other

general-purpose applications.

2. Features

2.1 Key features

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

s 16 kB on-chip Static RAM.

s 128/256 kB on-chip Flash Program Memory. 128-bit wide interface/accelerator

enables high speed 60 MHz operation.

s 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.

s EmbeddedICE-RT interface enables breakpoints and watch points. Interrupt

service routines can continue to execute whilst the foreground task is debugged

with the on-chip RealMonitor™ software.

s Embedded Trace Macrocell™ enables non-intrusive high speed real-time tracing

of instruction execution.

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

s Two 32-bit timers (with 4 capture and 4 compare channels), PWM unit (6 outputs),

Real Time Clock and Watchdog.

s Multiple serial interfaces including two UARTs (16C550), Fast I2C (400 kbits/s)

and two SPIs™.

s 60 MHz maximum CPU clock available from programmable on-chip

Phase-Locked Loop with settling time of 100 µs.

s Vectored Interrupt Controller with configurable priorities and vector addresses.
