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.
