1. General description

2. Features

2.1 Key features

The LPC2131/2132/2138 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 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.
