MC908AP32CFAE

The MC908AP32CFAE is an 8‑bit microcontroller from Freescale/NXP in the HCS08 MC908AP family. It combines an HCS08 CPU core with on‑chip memory and peripherals for embedded control.
Key points:
- Program memory and RAM: about 32 KB of on‑chip flash; on‑chip RAM ( RAM size varies by part revision but typically small to moderate).
- Peripherals: serial communications (SCI), SPI, I2C, ADC, timers, PWM, watchdog, and basic I/O.
- Power and clock: supports low‑power modes and a simple clock system suitable for embedded control.
- Debugging: typically supports a debug interface (BDM) for programming and debugging.
- Packaging: available in small to mid‑pin count packages (suitable for compact embedded boards).
- Use case: automotive body electronics, sensor/control applications, and other embedded systems needing an 8‑bit MCU with integrated peripherals.
- Development: commonly programmed with CodeWarrior for HCS08 or other toolchains; consult the official datasheet for exact memory map, peripherals, and package options.
For precise specs, see the MC908AP32CFAE datasheet.
