• System Performance  Fixed 20 MHz clock rate providing deterministic processing performance for legacy and embedded workloads.
• Power & I/O  5 V I/O voltage level compatible with 5 V embedded systems.
• Interfaces  Includes SCI (Serial Communication Interface) for serial peripheral and communications integration.
• Package & Mounting  179‑PGA package (179‑PGA, 47.24x47.24) designed for through‑hole mounting and socketed board layouts.
• Operating Range  Specified operating temperature range of 0 °C to 70 °C for commercial‑grade embedded applications.
• Environmental Compliance  RoHS compliant.
• MC68EC040 Variant Notes  As a member of the MC68040 family, documentation indicates that floating‑point and memory management unit details do not apply to the MC68EC040 variant; refer to the family user manual for applicable device differences.

Typical Applications

• Embedded control systems  Use the 32‑bit 68040 core and SCI interface for control logic, protocol handling, and peripheral management in embedded products.
• Industrial equipment  Through‑hole 179‑PGA package simplifies replacement, prototyping, and board‑level serviceability in industrial assemblies.
• Legacy system maintenance  Drop‑in compatible form factor and 5 V signalling make it suitable for maintaining or upgrading legacy M68040‑based electronics.
• Development and prototyping  Socketable PGA package facilitates development, evaluation, and firmware iteration on bench systems and prototype boards.

Unique Advantages

• Socketable PGA package: 179‑PGA through‑hole format enables easy insertion, removal, and board‑level servicing for development and repair.
• Clear, constrained thermal range: Specification of 0 °C to 70 °C allows straightforward thermal planning for commercial embedded applications.
• Single 32‑bit processing core: Simple, deterministic 68040 core operation at 20 MHz fits applications that require predictable performance.
• Standard 5 V I/O: Compatibility with 5 V system logic reduces level‑shifting requirements in existing 5 V designs.
• Serial communication support: Integrated SCI simplifies connection to peripherals, modems, and serial devices without adding discrete UART components.
• RoHS compliant: Helps satisfy environmental and regulatory requirements for finished products.
