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.
