The LPC11Axx MCU family is an Arm® Cortex®-M0 based low-cost 32-bit MCU family operating at CPU frequencies of up to 50 MHz. The LPC11Cxx MCU family is designed for 8/16-bit microcontroller operations, offering performance, low power, simple instruction set with reduced code size compared to existing 8/16-bit architectures.
Analog/mixed-signal subsystems can be configured by software from interconnected digital and analog peripherals. The digital peripherals of the LPC11Axx MCU family includes up to 32 KB of flash memory, up to 8 KB of SRAM data memory, up to 4 KB of EEPROM data memory, a fast-mode Plus I2C-bus interface, a RS-485/EIA-485 USART, 2 SSP controllers, 4 general purpose counters/timers, and up to 42 general purpose I/O pins. In addition, the analog peripherals include a 1-bit ADC, a 10-bit DAC, an analog comparator, a temperature sensor, an internal voltage reference and under-voltage lockout (UVLO) protection.
