MC68332GCEH25

Microcontrollers Overview

The MC68332GCEH25 is a 32-bit modular microcontroller from the M683xx series, manufactured by NXP Semiconductors. It features a CPU32 core with a 2 Kbyte static RAM module and operates at a maximum clock frequency of 20 MHz. The device is housed in a QFP-132 package and supports an operating temperature range of -40°C to +85°C. Key peripherals include a Time Processor Unit (TPU), a Queued Serial Module (QSM), and System Integration Module (SIM). It utilizes SCI and SPI interfaces and complies with AEC-Q100 automotive qualification standards.

Microcontrollers Feature Summary

• Integrates a fully static CPU32 processor with virtual memory implementation and background debugging mode capabilities.
• Includes a dedicated Time Processor Unit (TPU) microengine with 16 independent programmable channels for precise timing functions.
• Features a Queued Serial Module (QSM) supporting both serial communication interface and queued serial peripheral interface protocols.
• Provides system integration through a common intermodule bus with programmable chip-select outputs and system protection logic.

Microcontrollers Applications

• Automotive engine control systems
• Industrial motor control applications
• High-performance embedded controller designs

Microcontrollers Procurement Notes

Verify component authenticity against official NXP documentation due to end-of-life status. Confirm that the specific suffix indicates the correct 20 MHz frequency and extended temperature grade. Ensure compatibility with existing PCB footprints for the QFP-132 package before finalizing procurement decisions.

Microcontrollers Selection Notes

Select this model when a 32-bit architecture with high-speed timer processing is required. The G-series designation typically denotes automotive-grade reliability. Verify that the 20 MHz speed meets system timing requirements and that the QFP-132 package fits the mechanical constraints of the target enclosure.
