MC68360CZQ25L

Microprocessors Overview

The MC68360CZQ25L is a QUad Integrated Communications Controller (QUICC) microprocessor. It integrates four Serial Communication Controllers (SCCs), two Serial Management Controllers (SMCs), and one Serial Peripheral Interface (SPI). The device supports HDLC bus priority mode, full duplex Ethernet operation, hardware Centronics support, and IDMA channel status register updates.

Microprocessors Feature Summary

• Supports full duplex Ethernet operation via the Ethernet Mode Register
• Includes hardware support for Centronics interface functionality
• Features updated IDMA channel status registers to manage transfer events

Microprocessors Applications

• HDLC bus communication systems
• Ethernet network interfaces
• Centronics peripheral connections

Microprocessors Procurement Notes

Verify the specific revision B mask number C69T to ensure compatibility with required errata fixes. Confirm that the system design accounts for the increased Heart Beat window duration of 4mSec. Ensure software initialization correctly handles the updated IDMA channel status register clearing procedures as defined in the documentation.

Microprocessors Selection Notes

Select this component when integrating multiple serial communication channels within a single processor package. The device is suitable for applications requiring simultaneous SCC, SMC, and SPI operations. Consider the Revision B hardware fixes if previous versions exhibited issues with TRIS pin tristating or collision detection timing.

Microprocessors Part Context

The MC68360 is part of the QUICC family, designed as a versatile one-chip integrated microprocessor and peripheral combination. It serves as a high-performance successor to earlier models like the MC68302, offering increased flexibility and major capability extensions for controller applications.

Microprocessors Replacement Considerations

Revision B devices are visually marked with mask number C69T. Earlier revisions A0 and A1 use mask numbers 0C63T and 1C63T respectively. Verify the mask number on the component to determine the specific hardware revision and associated feature set.
