Product data sheet
1. General description
The LPC1102 is an ARM Cortex-M0 based, low-cost 32-bit MCU, 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 LPC1102 operates at CPU frequencies of up to 50 MHz.
The peripheral complement of the LPC1102 includes 32 kB of flash memory, 8 kB of data
memory, one RS-485/EIA-485 UART, one SPI interface with SSP features, four general
purpose counter/timers, a 10-bit ADC, and 11 general purpose I/O pins.
