MC68040FE40V

The MC68040FE40V from NXP Semiconductors is a single‑core, 32‑bit microprocessor based on the 68040 core, operating at 40 MHz for embedded system applications. It is supplied in a surface‑mount 184‑CQFP package (31.3 × 31.3 mm) for compact board integration.

Key hardware attributes include 5 V I/O, an SCI serial interface, and an operating temperature range of 0 °C to 70 °C. The device is RoHS compliant and is part of the M68040 family documented in the M68040 user’s manual.

Key Features

• Core and Architecture 68040 core — single 32‑bit processing core suitable for embedded program execution.
• Clock Speed 40 MHz operating frequency for steady processing throughput.
• Power and I/O 5 V I/O voltage level compatible with 5 V system logic.
• Package & Mounting 184‑CQFP (31.3 × 31.3 mm) surface‑mount package (package case listed as 184‑BCQFP) for board‑level assembly.
• Interfaces Includes an SCI (Serial Communication Interface) for serial peripheral and device connectivity.
• Operating Range Rated for operation from 0 °C to 70 °C.
• Environmental Compliance & Documentation RoHS compliant. Supported by the M68040 user’s manual which documents the integer unit and memory management aspects of the M68040 family.

Typical Applications

• Embedded systems — Primary 32‑bit processing for embedded control and application tasks that require a 68040 core at 40 MHz.
• Surface‑mount PCB designs — Compact 184‑CQFP package suited to dense board layouts and surface‑mount assembly processes.
• Serial communication devices — On‑chip SCI interface for device control, telemetry, or peripheral communication.

Unique Advantages

• Single 32‑bit processor core: Offers a straightforward, established architecture for embedded software development.
• Predictable 40 MHz operation: Fixed clock speed provides consistent processing capability for timing‑sensitive tasks.
