MM908E625ACEK

Overview

The MM908E625ACEK is an integrated automotive controller combining a high-performance HC08 microcontroller with a SMARTMOS analog control IC in a single 54-pin SOICW-EP package. It features a 16 KB flash memory, 512 bytes of RAM, and a 10-bit ADC. The analog section provides four half-bridge outputs, one low RDS(ON) high-side output, and a LIN physical layer. Operating within a supply voltage range of 8 V to 18 V and an ambient temperature range of -40 °C to +85 °C, it includes autonomous watchdog functionality and Hall-effect sensor inputs for robust motor control applications.

Feature Summary

• Integrated M68HC908EY16 core with 16 KB Flash, 512 B RAM, and 10-bit ADC
• SMARTMOS analog die with four half-bridge and one high-side driver outputs
• Built-in LIN physical layer for single-wire serial communication
• Autonomous watchdog with cyclic wake-up and internal clock generation module

Applications

• Automotive mirror control systems
• Door lock actuators
• Light-leveling mechanisms

Procurement Notes

Verify the EK suffix indicates the standard tube packaging for this specific part number variant. Confirm that the device status remains active or check for end-of-life notifications as automotive components frequently undergo lifecycle changes. Ensure compatibility with the 54-SOICW-EP thermal pad requirements during PCB layout.

Selection Notes

Select this component when a combined MCU and power driver solution is required to reduce PCB space. The integrated LIN transceiver eliminates external components for bus communication. Verify that the 16 KB program memory and 512 bytes of RAM are sufficient for the application logic before choosing over larger capacity variants.

Part Context

This device belongs to the 908E series of integrated motor controllers. It merges the M68HC08 CPU architecture with SMARTMOS technology, allowing for direct control of inductive loads without separate driver ICs. The integration simplifies design by housing power switches, diagnostics, and communication interfaces in one package.

Replacement Considerations

Check for the MM908E624ACEWR2 if tape-and-reel packaging is required instead of tubes. Verify pinout compatibility with existing designs when considering other members of the 908E family.
