LPC1311/13/42/43

32-bit ARM Cortex-M3 microcontroller; up to 32 kB flash and

8 kB SRAM; USB device

Rev. 5 — 6 June 2012

Product data sheet

1. General description

The LPC1311/13/42/43 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 LPC1311/13/42/43 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 LPC1311/13/42/43 includes up to 32 kB of flash

memory, up to 8 kB of data memory, USB Device (LPC1342/43 only), one Fast-mode Plus

I²C-bus interface, one UART, four general purpose timers, and up to 42 general purpose

I/O pins.

Remark: The LPC1311/13/42/43 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 V_DDlevel.

• Programmable pseudo open-drain mode for GPIO pins.

2. Features and benefits

 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 LPC1342/43 only).

 On LPC1342/43: USB MSC and HID on-chip drivers.
