1.1 Introduction

The LPC13xx are ARM Cortex-M3 based microcontrollers for embedded applications

featuring a high level of integration and low power consumption. The ARM Cortex-M3 is a

next generation core that offers system enhancements such as enhanced debug features

and a higher level of support block integration.

The LPC13xx operate at CPU frequencies of up to 72 MHz. The ARM Cortex-M3 CPU

incorporates a 3-stage pipeline and uses a Harvard architecture with separate local

instruction and data buses as well as a third bus for peripherals. The ARM Cortex-M3

CPU also includes an internal prefetch unit that supports speculative branching.

The peripheral complement of the LPC13xx series includes up to 32 kB of flash memory,

up to 8 kB of data memory, USB Device, one Fast-mode Plus (FM+) I2C interface, one

UART, four general purpose timers, and up to 42 general purpose I/O pins.

1.2 How to read this manual

This user manual describes parts LPC1311, LPC1313, LPC1342, LPC1343. Part-specific

features and registers are listed at the beginning of each chapter.

Remark: The LPC13xx series consists of the LPC1300 series (parts LPC1311/13/42/43)

and the LPC1300L series (parts LPC1311/01 and LPC1313/01). The LPC1300L series

features the following enhancements over the LPC1300 series:

•Power profiles with lower power consumption in Active and Sleep modes.

•Four levels for BOD forced reset.

•Second SSP controller (LPC1313FBD48/01 only).

•Windowed Watchdog Timer (WWDT).

•Internal pull-up resistors pull up pins to full VDD level.

•Programmable pseudo open-drain mode for GPIO pins.

1.3 Features

•ARM Cortex-M3 processor, running at frequencies of up to 72 MHz.

•ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC).

•32 kB (LPC1343/13)/16 kB (LPC1342)/8 kB (LPC1311) on-chip flash programming

memory.

•8 kB (LPC1343/13)/4 kB (LPC1342/11) SRAM.

•In-System Programming (ISP) and In-Application Programming (IAP) via on-chip

bootloader software.

•Selectable boot-up: UART or USB (USB on LPC134x only).

•On LPC134x: USB MSC and HID on-chip drivers.

•Serial interfaces:
