Product data sheet
1. General description
The LPC1111/12/13/14 are a ARM Cortex-M0 based, low-cost 32-bit MCU family,
designed for 8/16-bit microcontroller applications, offering performance, low power, simple
instruction set and memory addressing together with reduced code size compared to
existing 8/16-bit architectures.
The LPC1111/12/13/14 operate at CPU frequencies of up to 50 MHz.
The peripheral complement of the LPC1111/12/13/14 includes up to 32 kB of flash
memory, up to 8 kB of data memory, one Fast-mode Plus I²C-bus interface, one
RS-485/EIA-485 UART, up to two SPI interfaces with SSP features, four general purpose
counter/timers, a 10-bit ADC, and up to 42 general purpose I/O pins.
