Description
The MC68HC908MR8CFA is an 8-bit microcontroller from NXP (formerly Motorola), part of the HC08 family. It features:
- 8-bit HC08 core (up to 8 MHz clock speed)
- 8 KB Flash memory (reprogrammable)
- 384 bytes RAM
- 16-bit timer, PWM, and 8-channel 8-bit ADC
- SCI & SPI for serial communication
- 20 I/O pins (multiplexed with peripherals)
- Low-power modes for energy efficiency
It’s designed for embedded applications like motor control, industrial systems, and consumer electronics. The CFA suffix indicates a 48-pin LQFP package.
Key strengths include low cost, ease of development (using HC08 toolchains), and robust peripherals for control tasks. However, it lacks modern features like built-in USB or CAN.
For programming, tools like CodeWarrior or P&E Micro debuggers are commonly used.
