The LPC84x from NXP Semiconductors is an ARM Cortex-M0+ based, low-cost 32-bit MCU family operating at CPU frequencies of up to 30 MHz, supporting up to 64 KB of Flash memory and 16 KB of SRAM. The LPC84x family features exceptional power efficiency with down to 90 µA/MHz (active) in low-current mode using the free running oscillator (FRO) as the clock source. The peripheral complement of the LPC84x includes a CRC engine, four I2C bus interfaces, up to five USARTs, up to two SPI interfaces, capacitive touch interface, one multi-rate timer, self-wake-up timer, SCTimer/PWM, one general purpose 32-bit counter/timer, a DMA, one 12-bit ADC, two 10-bit DACs, one analog comparator, function-configurable I/O ports through a switch matrix, an input pattern match engine, and up to 54 general-purpose I/O pins.
