MC68EN360AI25L

Microprocessors Overview

The MC68EN360AI25L is a QUad Integrated Communication Controller (QUICC) microprocessor IC from the M683xx series. It features a CPU32+ core operating at 25 MHz with a 32-bit architecture. The device integrates four Serial Communications Controllers (SCCs), two Serial Management Controllers (SMCs), and one SPI interface, along with a Communications Processor Module (CPM). Key specifications include a 32-bit data bus, up to 32 address lines, and support for Ethernet on SCC1. It operates within a temperature range of 0°C to 70°C.

Microprocessors Feature Summary

• Integrates a CPU32+ processor core with byte-misaligned addressing capabilities and background debug mode.
• Includes a Communications Processor Module (CPM) with RISC controller functionality and 224 buffer descriptors.
• Features four general-purpose timers and two independent Direct Memory Access (IDMA) controllers.
• Supports slave mode operation for system expansion and MC68040 companion mode integration.

Microprocessors Applications

• Ethernet LAN implementations
• HDLC/SDLC communication systems
• T1 line and frame relay connections
• AppleTalk network interfaces

Microprocessors Procurement Notes

Verify the specific suffix 'AI' against official NXP documentation to confirm package type and environmental rating. Confirm RoHS compliance status as older M683xx variants may differ. Check for obsolete part status and ensure long-term supply availability meets project requirements before finalizing procurement.

Microprocessors Selection Notes

Select this component when designing systems requiring high-integration serial communications and Ethernet support. The CPU32+ core offers compatibility with existing M68000 software tools while providing enhanced performance. Consider the MC68040 companion mode if higher processing power is needed alongside QUICC peripheral management.

Microprocessors Part Context

The MC68EN360AI25L belongs to the M683xx family, representing a next-generation evolution of the MC68302. It utilizes the Intermodular Bus (IMB) architecture common to the M68300 family. This design allows for increased flexibility and integration compared to previous generations, serving as a versatile single-chip solution for controller applications.

Microprocessors Replacement Considerations

The MC68360RC25 serves as a Pin Grid Array variant within the same functional family. Designers upgrading from the MC68302 must account for pinout differences and modified register addresses during hardware and software migration.
