Product details
Overview
MC68376BACFT20 from NXP (formerly Motorola) is a 16-bit CISC microcontroller with integrated Time Processing Unit (TPU), CAN 2.0A/B controller, and 20.97 MHz CPU clock. It features 160-pin QFP packaging, on-chip ROM mask option (blank), and operates from –40 to +85 °C. It serves as a real-time control engine in automotive powertrain and industrial motion systems.
For engineers reviewing the MC68376BACFT20 datasheet, MC68376BACFT20 pinout, MC68376BACFT20 application, or MC68376BACFT20 equivalent, key selection criteria include TPU event timing resolution, dual CAN channel support, 16-bit external bus interface timing, and temperature-grade compatibility for under-hood or factory-floor deployment.
Technical Context
The MC68376BACFT20 integrates a CPU32 core with 20.97 MHz maximum operation, a 32-channel Time Processing Unit (TPU) supporting input capture, output compare, and pulse-width modulation with sub-microsecond resolution, and a dual CAN 2.0A/B controller with message buffers and programmable bit timing. Its external bus interface supports 16-bit data/24-bit address multiplexing with configurable wait-state generation.
It includes 8-channel 10-bit ADC (AN0–AN59), analog reference inputs (VRH/VRL), dedicated analog supply (VDDA/VSSA), and multiple interrupt sources including 8-level priority IRQ lines (PF0–PF7). The device uses a 160-pin QFP package with defined power/ground pin distribution and crystal oscillator pins (XTAL/EXTAL) for system clock derivation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC68376BAVFT20 | Same core, TPU, CAN, and pinout; rated for –40 to +105 °C operating range | Suitable for under-hood automotive or high-ambient industrial enclosures where extended temperature tolerance is required | Select when ambient operating temperature exceeds +85 °C but full +125 °C grade is unnecessary |
| MC9328MX1CZK | ARM920T core, 200 MHz, no integrated TPU or CAN; requires external CAN transceivers and timing peripherals | Targeted at higher-throughput HMI or protocol gateway applications rather than deterministic real-time control | Choose only if migrating to ARM architecture and accepting added component count and software complexity for increased MIPS |
Compared with MC68376BACFT20, MC68376BAVFT20 offers identical functionality with extended temperature rating, while MC9328MX1CZK trades deterministic timing capability for raw processing throughput - making the former a direct upgrade path and the latter a platform shift requiring full firmware redesign.

FAQ
What is the maximum operating frequency of the MC68376BACFT20?
The MC68376BACFT20 operates at a fixed maximum frequency of 20.97 MHz, derived from its internal PLL configuration and crystal oscillator input. This frequency is specified for the –40 to +85 °C temperature range and defines the upper bound for CPU instruction execution, TPU timing resolution, and CAN bit-rate generation. The MC68376BACFT20 does not support dynamic frequency scaling or overclocking beyond this value.
Does the MC68376BACFT20 include on-chip flash or ROM memory?
The MC68376BACFT20 features a blank mask-programmable ROM - meaning it contains no factory-programmed firmware and requires customer-specific code to be written during production. It does not include flash memory, EEPROM, or RAM larger than the on-chip 2 KB RAM used for stack and variables. External memory is accessed via its 16-bit data/24-bit address bus.
How many CAN interfaces does the MC68376BACFT20 support?
The MC68376BACFT20 integrates two independent CAN 2.0A/B-compliant controllers (CAN0 and CAN1), each with dedicated transmit (CANTX0/CANTX1) and receive (CANRX0/CANRX1) pins. Both controllers support programmable bit timing, message filtering, and up to 16 message objects - enabling dual-bus architectures such as powertrain + chassis networks without external CAN controllers.
What is the function of the TPU in the MC68376BACFT20?
The Time Processing Unit (TPU) in the MC68376BACFT20 is a dedicated 32-channel hardware timing peripheral that offloads precise event capture, output compare, and PWM generation from the CPU32 core. Each channel operates independently with sub-microsecond resolution, allowing simultaneous management of crankshaft position sensing, injector timing, and motor phase control - critical for deterministic real-time performance in engine and motion control.
Is the MC68376BACFT20 pin-compatible with other MC68376 variants?
Yes, the MC68376BACFT20 shares identical 160-pin QFP pinout and signal mapping with all MC68376 variants including MC68376BAVFT20 and MC68376BAMFT20. Differences are limited to temperature grade (–40 to +85 °C vs. +105/+125 °C) and ordering suffixes - enabling drop-in replacement in existing PCB layouts when thermal requirements change.
