MC68040RC40A

The MC68040RC40A is a single-core 68040-series microprocessor IC delivering a 32-bit architecture at a 40 MHz clock rate. Packaged in a 179-PGA through-hole form factor, it is intended for embedded applications requiring a classic M68040 family implementation.

Designed within the M68040 documentation framework, this device is covered by the M68040 user manual which details the core integer and memory management architecture and provides programming and operation guidance for designs using M68040-series processors.

Key Features

• Core & Architecture  68040 core, single 32-bit processing core as part of the M68040 series.
• Operating Speed  40 MHz clock speed suitable for legacy and embedded control tasks.
• I/O Voltage  5 V I/O compatibility for designs using standard 5 V logic domains.
• Interfaces  Includes SCI as an additional interface for serial communication integration.
• Package & Mounting  179-PGA supplier device package (47.24×47.24) with through-hole mounting for easy prototyping and field replacement.
• Operating Range  Specified operating temperature range of 0 °C to 70 °C for commercial-temperature applications.
• Environmental Compliance  RoHS compliant to support environmentally conscious design choices.
• Documentation  Part of the M68040 family documented in the M68040 user manual covering integer and memory management units and programming guidance.

Typical Applications
