30 MHz Cortex-M0+ with 16 KB Flash — what it fits
The NXP LPC822M101JHI33K is a 32-bit ARM Cortex-M0+ MCU from the LPC82x series, clocked at 30 MHz with 16 KB Flash and 4 KB SRAM. That memory map is sized for a single firmware image with a modest data buffer — think sensor polling loops, basic motor commutation, or a Modbus RTU slave stack. The 29 I/O lines in a 32-HVQFN package give you enough pins to capture a 12-bit SAR ADC on twelve channels and still run I²C, SPI, or UART peripherals without remapping.
For a BOM line needing a stable 32-bit MCU, this is a safe pick.
Peripheral set and ADC
The 12-channel 12-bit SAR ADC samples at rates adequate for current-sense or thermistor readout in a control loop. DMA offloads peripheral-to-memory transfers without stalling the core.
