MC908GR4CPE

Microcontrollers Overview

The MC908GR4CPE is an 8-bit microcontroller unit belonging to the M68HC08 family, manufactured by Freescale Semiconductor. It features a 7.5 KB FLASH program memory and a 28-pin DIP package. The device integrates a high-performance CPU core with on-chip in-application programmable memory and supports internal oscillator configurations.

Microcontrollers Feature Summary

• Integrates a high-performance M68HC08 CPU core with fully upward-compatible object code for the M68HC05 family
• Supports in-system FLASH programming with on-chip internal program/erase voltage generation
• Includes a configuration register allowing for low-voltage inhibit trip point selection

Microcontrollers Applications

• General-purpose embedded control systems
• Industrial automation controllers
• Consumer electronics logic control

Microcontrollers Procurement Notes

Verify the specific datasheet revision (e.g., Rev. 4) against the manufacturing date code to ensure compatibility with current design requirements. Confirm that the 28-pin DIP package matches the target PCB footprint and that the operating voltage range aligns with the system power supply specifications.

Microcontrollers Selection Notes

Select this component when a robust 8-bit architecture with moderate program memory capacity is required. The inclusion of an internal trimmable oscillator reduces external component count. Ensure the application does not require higher clock speeds or larger I/O counts available in other members of the GR series.

Microcontrollers Part Context

This part is a member of the M68HC08 family, which utilizes the enhanced CPU08 core. It shares architectural similarities with the MC908GR8CPE but offers reduced memory size. The device is designed for cost-sensitive applications requiring reliable 8-bit processing capabilities.
