16-bit CPU12 at 25 MHz — what the core brings
The NXP MC9SDG256BCFUR2 is a 16-bit microcontroller built around the CPU12 core, running at 25 MHz.
2.35 V supply — low-voltage operation
This part runs from a 2.35 V supply, which places it in the low-voltage MCU tier. That matters for battery-powered or energy-harvesting designs where every millivolt of headroom costs you in quiescent current.
Peripheral set: CAN, I²C, SCI, SPI, PWM, WDT
The MC9SDG256BCFUR2 includes CANbus, I²C, SCI (UART), and SPI serial interfaces, plus PWM and a watchdog timer. With 59 I/O lines, there's enough GPIO for parallel displays, keypad matrices, or sensor arrays without external expanders.
8-channel 10-bit ADC — analog front end
An 8-channel, 10-bit successive-approximation ADC is integrated on-chip.
The PQFP80 package is a surface-mount quad flat pack with 80 leads — a common footprint for mid-density MCUs that balances I/O count with board-level inspectability.
