1. Introduction

The LPC29xx combine an 125 MHz ARM968E-S CPU core, Full Speed USB 2.0 OTG

and device, CAN and LIN, up to 56 kB SRAM, up to 768 kB flash memory, external

memory interface, two or three 10-bit ADCs, and multiple serial and parallel interfaces in a

single chip targeted at consumer, industrial, medical, and communication. To optimize

system power consumption, the LPC29xx has a very flexible Clock Generation Unit

(CGU) that provides dynamic clock gating and scaling.

2. About this user manual

This document describes the following parts: LPC2917/01, LPC2919/01, LPC2921,

LPC2923, LPC2925, LPC2926, LPC2927, LPC2929, LPC2930, and LPC2939.

Differences between the various parts as they apply to each block or peripheral are listed

at the beginning of each chapter. For an overview of features see Table 1–2.

3. General features

Remark: See Table 1–2 for feature details for each LPC29xx part.
