MC68LC040RC25A

The MC68LC040RC25A is a member of the MC68LC040 series 68040 microprocessors, featuring a single 32‑bit 68040 core running at 25 MHz. Designed for embedded applications, it provides deterministic 32‑bit integer processing with a serial communications interface (SCI) and 5 V I/O compatibility.

Packaged in a 179‑pin PGA (179‑PGA, 47.24 × 47.24) through‑hole package and rated for commercial temperature operation, this device is suited for embedded control, instrumentation, and legacy system maintenance where a socketed, serviceable processor is required.

Key Features

• Core Single 68040 32‑bit core running at 25 MHz, providing standardized M680x0 architecture processing for embedded control and signal handling.
• Voltage and I/O 5 V I/O voltage ensures compatibility with legacy 5 V logic domains and existing board designs.
• Package and Mounting 179‑PGA supplier device package (179‑BEPGA) with dimensions listed as 47.24 × 47.24 and through‑hole mounting for easy socketing, replacement, and prototyping.
• Interfaces Integrated SCI (Serial Communications Interface) for asynchronous serial communication and peripheral connectivity.
• Graphics and FPU No graphics acceleration is provided. Documentation for the MC68LC040 indicates floating‑point information does not apply to this variant.
• Operating Range Commercial temperature range rated from 0 °C to 70 °C.
• Environmental RoHS compliant.

Typical Applications

• Industrial Control Deterministic 32‑bit processing at 25 MHz and 5 V I/O make this device suitable for control and sequencing tasks in embedded controllers.
• Embedded Instrumentation Use in measurement, data‑acquisition, and instrument control systems where serial communications (SCI) and integer processing are required.
• Prototyping & Field Service Through‑hole 179‑PGA package supports socketed prototypes and field‑replaceable upgrades in legacy equipment.
• Legacy System Maintenance Suitable for sustaining or refurbishing existing systems built around the M680x0 architecture.

Unique Advantages

• 32‑Bit M68040 Architecture: Delivers a consistent M680x0 instruction set and 32‑bit integer performance for embedded software compatibility.
• Through‑Hole 179‑PGA Packaging: Large PGA footprint and through‑hole mounting simplify socketed implementations and board-level servicing.
• 5 V I/O Compatibility: Integrates into legacy 5 V systems without additional level‑shifting components.
• Integrated SCI: On‑chip serial communications interface reduces external component count for UART/serial links.
• Commercial Temperature Rating: Rated 0 °C to 70 °C for mainstream embedded applications.
• RoHS Compliant: Meets environmental compliance requirements for lead‑free designs.
