Preliminary data sheet

1. General description

The LPC2131/2132/2134/2136/2138 microcontrollers are based on a 32/16 bit

ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combines

the microcontroller with 32 kB, 64 kB, 128 kB, 256 kB and 512 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.

Due to their tiny size and low power consumption, these microcontrollers are ideal for

applications where miniaturization is a key requirement, such as access control and

point-of-sale. With a wide range of serial communications interfaces and on-chip SRAM

options of 8/16/32 kB, they are very well suited for communication gateways and protocol

converters, soft modems, voice recognition and low end imaging, providing both large

buffer size and high processing power. Various 32-bit timers, single or dual 10-bit

8 channel ADC(s), 10-bit DAC, PWM channels and 47 GPIO lines with up to nine edge or

level sensitive external interrupt pins make these microcontrollers particularly suitable for

industrial control and medical systems.
