The Microchip PIC32MX174F256B-V/MM is a 32-bit MCU built around the MIPS32 M4K core, clocked at 72 MHz. The part is part of the PIC XLP 32MX family, which means it balances performance with low-power operation for always-on or battery-backed systems.

256 KB Flash / 64 KB RAM — memory budget for control firmware
256 KB of Flash is enough for a full AUTOSAR or bare-metal motor-control stack with a bootloader. The 64 KB RAM supports DMA transfers and multiple buffered communication channels. The 10-channel 10-bit ADC handles analog sensor inputs like throttle position, current sense, or temperature feedback without an external ADC.
21 I/O and serial connectivity — fitting into a 28-pin package
With 21 I/O pins in a 28-VQFN exposed-pad package, the pin count is tight. The connectivity set includes I²C, SPI, UART, LIN, and IrDA — enough for CAN bridge, LIN slave, or sensor fusion nodes.
