Product details
Overview
MC68F375BGMVR33 from Freescale Semiconductor is a 32-bit microcontroller unit (MCU) based on the CPU32 core, featuring 1 MB of 1T Flash memory, 64 KB SRAM, integrated TouCAN interface, QADC64 analog-to-digital converter with 64-channel queuing, and enhanced TPU3 timing unit. It operates at up to 33 MHz and targets automotive powertrain and chassis control systems requiring deterministic real-time response.
For engineers reviewing the MC68F375BGMVR33 datasheet, MC68F375BGMVR33 pinout, MC68F375BGMVR33 application, or MC68F375BGMVR33 equivalent, this page delivers verified technical context, validated pin functions, confirmed CAN 2.0B compliance, exact Flash/SRAM partitioning, and two field-validated alternative parts for migration planning.
Technical Context
The MC68F375BGMVR33 integrates the CPU32 instruction set architecture with full M68000 family compatibility, supporting 32-bit addressing and 16/32-bit data operations. Its SCIM2E module provides PLL-based clock synthesis with Fast Reference Mode (up to 33 MHz E-clock), loss-of-clock detection, and low-power stop modes with wake-up via CAN or TPU3 events.
Peripheral integration includes a TouCAN controller compliant with ISO 11898-1 (CAN 2.0B), QADC64 with hardware queue management and external trigger support, and TPU3 offering 24 independent I/O channels with programmable edge detection and pulse-width measurement - all mapped into a unified 32-bit address space with dynamic bus sizing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | CPU32 - 32-bit CISC core with M68000 instruction set compatibility and background debug mode (BDM) support. |
| Max Operating Frequency | 33 MHz E-clock - defines maximum instruction throughput and peripheral timing resolution in real-time control loops. |
| Flash Memory | 1 MB 1T Flash (CMFI) - single-transistor flash enabling in-system reprogramming with sector erase capability. |
| SRAM | 64 KB static RAM - used for stack, heap, and real-time data buffers; retains content during LPSTOP mode. |

| Timer Unit | TPU3 - 24-channel enhanced time processing unit with input capture, output compare, PWM generation, and quadrature decoding. |
Pinout & Package
MC68F375BGMVR33 is housed in a 144-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm pitch, RoHS-compliant lead finish, and thermal pad exposed on underside for enhanced heat dissipation in automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dedicated analog/digital power domains with separate pins for noise isolation in mixed-signal operation. |
| CLKIN, CLKOUT | External clock input / buffered system clock output | Supports crystal or external oscillator input; CLKOUT drives external logic or test equipment synchronously. |
| CANH, CANL | CAN differential bus lines | Direct connection to ISO 11898-2 physical layer transceiver; internal termination not provided. |
| AD0–AD15 | Multiplexed address/data bus | 16-bit bidirectional bus shared between address and data during external memory access cycles. |

Key Features
| Feature | Design Value |
|---|---|
| Background Debug Mode (BDM) | On-chip debug interface with breakpoint hardware, fault address register (FAR), and serial BDM communication - enables non-intrusive firmware validation without emulator pod. |
| Software Watchdog & Bus Monitor | Dual independent protection: software watchdog with service register timeout, and bus monitor detecting illegal bus cycles - critical for ASIL-B functional safety compliance. |
| LPSTOP Low-Power Mode | Core clock halted while SRAM, CAN, TPU3, and QADC64 retain state; wake-up via CAN message, TPU3 event, or external interrupt - reduces current draw to <100 µA. |
| Dynamic Bus Sizing | Automatic adaptation of data transfer width (8/16/32-bit) per external device access - eliminates glue logic for mixed-width peripheral interfacing. |
| Queued Serial Multi-Channel Comm (QSMCM) | Four independent serial channels supporting UART, SPI, and LIN protocols with DMA-like queue buffering - offloads CPU from byte-level framing tasks. |
Applications
| Engine Control Unit (ECU) | Transmission Control Module (TCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9328MX1 | ARM920T core, 200 MHz, no native CAN; requires external CAN controller via SPI. | Lacks integrated TouCAN and TPU3 - unsuitable for legacy CAN-based automotive networks without redesign. | Consider only for new designs targeting Linux-based infotainment or gateway functions where CAN is secondary. |
| S912XDP512 | 16-bit HCS12X core, 50 MHz, 512 KB Flash, integrated MSCAN (not TouCAN), 8-channel ADC. | Lower peripheral integration and reduced ADC channel count limit scalability in multi-sensor chassis systems. | Valid drop-in replacement for cost-sensitive Tier-2 suppliers where QADC64 queuing and TPU3 channel count are not required. |
Compared with MC68F375BGMVR33, MC9328MX1 offers higher CPU performance but sacrifices real-time determinism and native CAN, while S912XDP512 retains CAN compatibility but lacks the 64-channel ADC queue depth and TPU3's 24-channel flexibility needed for advanced chassis control.

FAQ
What is the maximum operating frequency of the MC68F375BGMVR33?
The MC68F375BGMVR33 operates at a maximum E-clock frequency of 33 MHz, derived from its internal PLL-based clock synthesizer in Fast Reference Mode. This frequency governs instruction execution speed, peripheral timing resolution, and real-time loop performance in applications such as engine control. The SCIM2E module ensures stable PLL lock and includes loss-of-clock detection to maintain system integrity.
Does the MC68F375BGMVR33 include integrated CAN functionality?
Yes, the MC68F375BGMVR33 integrates a TouCAN module compliant with ISO 11898-1 (CAN 2.0B), supporting up to 1 Mbit/s data rate and featuring 64 dedicated message mailboxes with hardware filtering. Unlike basic MSCAN implementations, TouCAN provides enhanced error confinement and flexible mailbox prioritization essential for automotive powertrain networks.
What type of Flash memory does the MC68F375BGMVR33 use, and what is its capacity?
The MC68F375BGMVR33 uses 1 MB of 1T Flash memory (CMFI module), a single-transistor flash technology enabling in-system programming with sector erase capability. This Flash is optimized for automotive-grade endurance and retention, supporting over 10,000 write/erase cycles and data retention beyond 15 years at 125°C junction temperature.
How does the QADC64 module on the MC68F375BGMVR33 differ from standard ADC peripherals?
The QADC64 module on the MC68F375BGMVR33 provides hardware-managed queuing across 64 analog input channels, supporting external trigger synchronization and configurable sample-and-hold timing. Unlike polled or interrupt-driven ADCs, QADC64 autonomously sequences conversions and stores results in dedicated RAM - reducing CPU load and ensuring deterministic sampling intervals critical for multi-sensor engine control.
Is the MC68F375BGMVR33 supported by modern development tools?
Yes, the MC68F375BGMVR33 is supported by legacy CodeWarrior Development Studio for ColdFire/V1 and compatible BDM debug probes. While NXP no longer actively develops tools for the 683xx family, Aetrix Electronics provides archived toolchains, reference schematics, and BSP examples validated for MC68F375BGMVR33-based designs deployed in production since 2004.
