MC68302AG33C

Microprocessors Overview

The MC68302AG33C is a 32-bit microcontroller from the M68300 family, featuring a CPU32 core and operating at a maximum clock frequency of 33 MHz. It utilizes an LQFP-144 package for surface mount installation. The device includes a System Integration Module (SIM), General Purpose Timer (GPT), Queued Serial Module (QSM), and Integrated Data Link (IDL) interface. It supports DMA via DREQ/DACK signals and bus arbitration through BR/BG pins.

Microprocessors Feature Summary

• Integrated IDL bus controller for direct connection to IDL masters without external glue logic
• Queued Serial Module (QSM) supporting SCI and SPI protocols with hardware-managed data queues
• General Purpose Timer (GPT) providing capture/compare channels and programmable output waveforms
• CPU32 core with upward object code compatibility and support for background debugging mode

Microprocessors Applications

• Panel-mounted controllers requiring precise machine synchronization
• Remote I/O systems in distributed control architectures
• Industrial automation nodes utilizing IDL bus communication
• Multiprotocol processing applications integrating serial and timer peripherals

Microprocessors Procurement Notes

Verify component authenticity through authorized NXP distributors or certified secondary market suppliers. Confirm lot codes and date codes against current manufacturing records. Inspect packages for physical integrity and pin alignment prior to integration. Ensure static-safe handling procedures are followed during storage and assembly to prevent electrostatic discharge damage to the CMOS circuitry.

Microprocessors Selection Notes

Select this variant when a 33 MHz operating speed is required within the M68300 architecture. Choose based on the necessity for integrated IDL connectivity and QSM capabilities. Evaluate thermal management requirements for the LQFP-144 package under maximum load conditions. Consider legacy software compatibility if migrating from earlier M683xx series components.

Microprocessors Part Context

Part of the M68300 family designed for high-performance embedded control. Combines CPU32 processing with specialized peripheral subsystems. Designed for modular architecture implementation in industrial and automotive environments. Supports standard intermodule bus interfaces for system expansion.

Microprocessors Replacement Considerations

MC68302AG16C: Lower clock speed variant (16 MHz). MC68302AG25C: Intermediate clock speed variant (25 MHz). Verify pinout and register compatibility before substitution.
