NXP Semiconductors LPC11A13
The LPC11Axx are an 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 LPC11Axx operate at CPU frequencies of up to 50 MHz. The digital peripherals on the LPC11Axx include up to 32 kB of flash memory, up to 4 kB of EEPROM data memory, up to 8 kB of SRAM data memory, a Fast-mode Plus I2C-bus interface, a RS-485/EIA-485 USART, two SSP controllers, four general purpose counter/timers, and up to 42 general purpose I/O pins.
