MC9S12D64CFUE

MC9S12D64CFUE is an NXP/Freescale 16‑bit MCU from the HCS12D family. It combines a 16‑bit HCS12 CPU core with 64 KB of flash for code and about 4 KB of RAM, operating from a 2.7–5.5 V supply at up to roughly 50 MHz.
Key features:
- On‑chip peripherals: SCI/UARTs, SPI, I2C, ADC with multiple channels, 16‑bit timers, PWM, and a watchdog; interrupt controller; in‑system debug support.
- Power and safety: low‑power run/stop modes; automotive‑grade variants available.
- Memory/boot: standard flash with in‑system programming/back‑up options.
Typical uses: automotive and industrial controllers, motor control, instrumentation and other embedded systems needing a compact 16‑bit MCU.
Development: CodeWarrior for HCS12 (and related Freescale/NXP tools) with in‑circuit programming/debug via a BDM interface.
Package/suffix: CFUE denotes a specific device/package variant; refer to the datasheet for exact pinout, package, and temperature rating.
