The NXP LPC845M301JBD48E is a 32-bit ARM Cortex-M0+ microcontroller from the LPC84x series, clocked at 30 MHz with 64 KB Flash and 16 KB RAM. It packs 42 GPIO, a 12-bit ADC, dual 10-bit DAC, and I²C/SPI/USART connectivity into a 48-LQFP package. The -40 to 105 °C operating range suits industrial control, sensor nodes, and human-machine interface panels where the MCU sits near the process or in an outdoor enclosure.
30 MHz Cortex-M0+ — what the speed buys you
At 30 MHz the core handles control loops, capacitive touch scanning, and basic sensor fusion without external co-processors. The DMA peripheral offloads data transfers from the CPU, keeping throughput consistent even when the ADC and serial interfaces are active.
