NXP Semiconductors LPC84x 32-bit Arm® Cortex®-M0+ MCUs

NXP Semiconductors LPC84x 32-bit Arm® Cortex®-M0+ Microcontrollers offer a space-efficient, low-pin-count solution for basic microcontroller applications. Based on an ultra-efficient, 30MHz core, the LPC84x MCUs support up to 64KB of flash memory and 16KB of SRAM. LPC84x MCUs feature exceptional power efficiency in low-current mode using the Free Running Oscillator (FRO) 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, 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. NXP Semiconductors LPC84x Microcontrollers are offered in LQFP64, LQFP48, HVQFN48, and HVQFN33 packages for design flexibility.
