General Description

The LPC2114/2124 are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 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.

Overview

LPC2114/2124 Single-chip 16/32-bit microcontrollers; 128/256 kB ISP/IAP flash with 10-bit ADC Rev.

Key Features

  • 2.1 Key features brought by LPC2114/2124/01 devices.
  • 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.
  • Dedicated result registers for ADC(s) reduce interrupt overhead. The ADC pads are 5 V tolerant when configured for digital I/O function(s).
  • UART0/1 include fractional baud rate generator, auto-bauding capabilities and handshake flow-control fully implemented.
