The LPC11C22FBD48/301 is a 32-bit Microcontroller based on ARM Cortex-M0 core with RISC architecture operates at a maximum frequency of 50MHz. The device incorporates 16kB internal flash, 8kB internal RAM, four general purpose counters/timers, 8-channel 10-bit A/D converter with sample rates of up to 400ksps, high-speed CAN transceiver and 36 general-purpose I/O pins. This device also features peripherals like one UART, one inter-integrated circuit (I2C) and two serial peripheral interface (SPI) modules.
