Based on the ARM Cortex-M0+ core, LPC84x is a low-cost, 32-bit MCU family operating at frequencies of up to 30 MHz. The LPC84x MCU family supports up to 64 KB of flash memory and 16 KB of SRAM.
This family features exceptional power efficiency in low-current mode using the FRO as the clock source. The peripheral complement of the LPC84x MCU family includes a CRC engine, four I2C-bus interfaces, up to five UARTs, up to two SPI interfaces, capacitive touch interface (enablement coming in Q3), 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.
