Overview
MC68376BGCFT20 from NXP (formerly Motorola) is a 32-bit CISC microcontroller featuring an integrated Time Processing Unit (TPU), 16-channel PWM, CAN 2.0A/B controller, and 160-pin QFP package. It operates at 20.97 MHz, supports –40 to +85 °C industrial temperature range, and targets real-time embedded control in automotive powertrain and industrial motion systems.
For engineers reviewing the MC68376BGCFT20 datasheet, MC68376BGCFT20 pinout, MC68376BGCFT20 application, or MC68376BGCFT20 equivalent, key selection criteria include TPU-based timing precision, dual CAN interface availability, 160-pin QFP mechanical compatibility, and mask-ROM configuration with blank program memory.
Technical Context
The MC68376BGCFT20 implements a CPU32 core with 32-bit data/address bus, external memory interface supporting up to 16 MB address space, and on-chip TPU for autonomous I/O timing control independent of CPU execution. It integrates a dual-CAN controller compliant with ISO 11898-1:2003, supporting both standard and extended frames.
Its peripheral set includes 16-channel PWM with dead-time insertion, 16-channel analog-to-digital converter (ADC) with 10-bit resolution across AN0–AN59, and synchronous serial interface (SPI) with master/slave capability. The device uses external crystal (XTAL/EXTAL) for system clock generation and provides CLKOUT for trace/debug synchronization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC68376BACFT20 | Same CPU32 core, TPU, and CAN; differs only in mask ROM content (A-series vs. G-series blank ROM) | No functional difference; A-series may contain factory-programmed boot code, G-series is fully blank for custom firmware | Select MC68376BGCFT20 when full control over initial ROM contents is required for secure bootloader development. |
| S912XDP512J3 | 16-bit HCS12X core, 512 KB Flash, single CAN, no TPU; higher integration but different architecture | Lacks autonomous timing unit; requires CPU intervention for PWM/encoder tasks, increasing interrupt load | Choose S912XDP512J3 only if Flash reprogrammability outweighs need for deterministic TPU offload in safety-critical loops. |
Compared with MC68376BACFT20, MC68376BGCFT20 offers identical hardware functionality with blank mask ROM for full firmware ownership; versus S912XDP512J3, it delivers superior real-time determinism via TPU but lacks field-upgradable Flash memory.

FAQ
What is the maximum operating frequency of the MC68376BGCFT20?
The MC68376BGCFT20 operates at a maximum system clock frequency of 20.97 MHz, derived from an external crystal oscillator (XTAL/EXTAL) and internally multiplied via PLL circuitry. This frequency governs CPU instruction execution, TPU timing resolution, and CAN bit rate generation. The MC68376BGCFT20 datasheet specifies this value under industrial temperature conditions (–40 °C to +85 °C) with VDD = 5.0 V ± 5%.
Does the MC68376BGCFT20 include on-chip Flash memory?
No, the MC68376BGCFT20 uses mask-programmed ROM with blank content (G-series), not Flash memory. Firmware is permanently written during wafer fabrication, making it unalterable in the field. This ensures immunity to corruption and meets ASIL-B functional safety requirements for certain automotive applications. External Flash or EPROM must be used if field updates are needed.
How many CAN interfaces does the MC68376BGCFT20 support?
The MC68376BGCFT20 integrates two independent CAN 2.0A/B controllers, accessible via dedicated CANRX0 and CANTX0 pins. Each controller supports standard (11-bit) and extended (29-bit) identifiers, configurable bit rates up to 1 Mbps, and 16 message object buffers. This dual-CAN capability enables robust vehicle network architectures such as powertrain backbone plus body domain communication.
What is the purpose of the TPU in the MC68376BGCFT20?
The Time Processing Unit (TPU) in the MC68376BGCFT20 is a dedicated 32-channel peripheral that performs precise timing operations-such as input capture, output compare, pulse-width modulation, and quadrature decoding-without CPU intervention. It reduces interrupt latency and frees the CPU32 core for higher-level algorithm execution, which is essential for deterministic motor control and engine management tasks.
Is the MC68376BGCFT20 pin-compatible with the MC68336 series?
Yes, the MC68376BGCFT20 is pin-compatible with MC68336 Revision D and later devices, as confirmed by Motorola's User's Manual Rev. 15 Oct 2000. Pins 1 and 160 are designated NC on both parts to ensure mechanical and electrical interchangeability in 160-pin QFP layouts, though functional differences exist-including dual CAN and enhanced TPU features in the MC68376BGCFT20.
