The LPC822M101JHI33E is a 32-bit Microcontroller based on ARM Cortex-M0 core with RISC architecture operates at a maximum frequency of 30MHz. The device incorporates 16kB internal flash, 4kB internal RAM, one multi-rate timer, self-wake-up timer and state-configurable timer with PWM function (SCTimer/PWM), a DMA, 12-channel 12-bit A/D converter with sample rates of up to 1.2Msps, one analog comparator, function-configurable I/O ports through a switch matrix, an input pattern match engine and 29 general-purpose I/O pins. This device also features peripherals like three USARTs, four inter-integrated circuit (I2C) and two serial peripheral interface (SPI) modules.
