Product details
Overview
MC68F375MZP33R2 from Freescale Semiconductor is a 32-bit microcontroller unit (MCU) based on the CPU32 core, featuring integrated 1T Flash (512 KB), 32 KB SRAM, TouCAN interface, QADC64 analog-to-digital converter, and TPU3 time-processing unit. It operates at up to 33 MHz, supports background debug mode (BDM), and targets automotive and industrial real-time control applications requiring deterministic timing and CAN bus connectivity.
For engineers reviewing the MC68F375MZP33R2 datasheet, MC68F375MZP33R2 pinout, MC68F375MZP33R2 application, or MC68F375MZP33R2 equivalent, this page delivers verified technical context, module-level specifications, package mapping to PQFP-144, validated pin functions per Reference Manual Rev. 25 June 2003, and two confirmed alternative MCU options for CAN-enabled embedded control designs.
Technical Context
The MC68F375MZP33R2 integrates the CPU32 32-bit instruction set architecture with a tightly coupled SCIM2E system controller managing clock synthesis (PLL-based), reset sequencing, bus arbitration, and low-power stop modes. Its QADC64 module supports queued 10-bit conversion across up to 64 channels with external trigger synchronization.
It embeds a TouCAN 2.0B-compliant controller with message buffering and error handling, an Enhanced TPU3 for precise input capture/output compare, and DPTRAM for TPU emulation. The device uses a 144-pin PQFP package with multiplexed address/data bus and dedicated CANH/CANL pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9328MX1CZK | ARM920T core, 200 MHz, no integrated CAN; requires external CAN controller. | Higher compute throughput but lacks native CAN-suitable for gateway applications where CAN is offloaded to dedicated ICs. | Select when migrating to ARM architecture with Linux RTOS support and higher MIPS/watt, accepting added board complexity for CAN. |
| MC56F8323VFAE | DSP56800E core, 60 MHz, 64 KB Flash, 8 KB RAM, single CAN channel, no QADC64. | Optimized for motor control DSP tasks; limited analog acquisition capability versus QADC64's 64-channel queue. | Prefer for cost-sensitive brushless DC motor drives where ADC channel count and CAN message object depth are secondary to PWM resolution and current loop speed. |
Compared with MC68F375MZP33R2, MC9328MX1CZK offers superior processing headroom but increases BOM count and design validation effort due to external CAN, while MC56F8323VFAE reduces system cost and power in motor-centric applications but sacrifices analog channel scalability and CAN message object depth required for multi-node vehicle networks.

The MC68F375MZP33R2 belongs to Freescale's 683xx family of automotive-grade microcontrollers, engineered specifically for real-time engine and chassis control systems demanding CAN integration, deterministic interrupt latency, and robust qualification to AEC-Q100 Grade 2.
FAQ
What is the maximum operating frequency of the MC68F375MZP33R2?
The MC68F375MZP33R2 is rated for a maximum system clock frequency of 33 MHz, as specified in the Freescale MC68F375 Reference Manual (Rev. 25 June 2003). This frequency applies to the CPU32 core and all on-chip peripherals including the TouCAN controller and QADC64 module. Operation above this limit is not guaranteed and may result in timing violations or functional failure.
Does the MC68F375MZP33R2 include on-chip Flash memory, and what is its capacity?
Yes, the MC68F375MZP33R2 integrates 512 KB of 1T Flash memory, as documented in Section 1.3.9 (CMFI module) of the reference manual. This Flash supports in-application programming (IAP) and is qualified for 10,000 erase/write cycles with data retention exceeding 10 years at 85°C, making it suitable for field-upgradable automotive firmware.
What debugging interface does the MC68F375MZP33R2 support?
The MC68F375MZP33R2 implements Background Debug Mode (BDM) as its primary on-chip debug interface. As described in Section 3.10 of the reference manual, BDM provides serial communication over a single BKPT pin, enabling full register access, memory read/write, breakpoint insertion, and program execution control without halting real-time peripheral operation.
Is the MC68F375MZP33R2 pin-compatible with other members of the 683xx family?
No, the MC68F375MZP33R2 is not pin-compatible with earlier 683xx devices such as the MC68332 or MC68376. Its 144-pin PQFP footprint, multiplexed bus configuration (AD0–AD15 + A16–A23), and dedicated TouCAN pins differ significantly from 114-pin or 132-pin variants. PCB layout must be designed specifically for MC68F375MZP33R2.
What is the role of the SCIM2E module in the MC68F375MZP33R2?
The SCIM2E (Single-Chip Integration Module 2 Enhanced) in the MC68F375MZP33R2 serves as the central system controller, integrating clock synthesis (PLL), reset management, bus arbitration, interrupt prioritization, and low-power stop mode control. Per Section 4 of the reference manual, it eliminates the need for external glue logic and provides deterministic startup and fault-recovery behavior essential for automotive safety-critical applications.
