NXP Semiconductors MC68376BGVAB25

Overview

MC68376BGVAB25 from NXP (formerly Motorola) is a 16-bit CISC microcontroller with integrated Time Processing Unit (TPU), CAN 2.0A/B controller, 256 KB on-chip ROM, and 160-pin QFP package. It operates at 25 MHz, supports −40 °C to +105 °C industrial temperature range, and targets real-time embedded control in automotive powertrain and industrial motion systems.

For engineers reviewing the MC68376BGVAB25 datasheet, MC68376BGVAB25 pinout, MC68376BGVAB25 application, or MC68376BGVAB25 equivalent, key selection criteria include TPU event timing resolution, dual CAN channel support, ROM mask version B, and 160-pin QFP mechanical compatibility with legacy MC68336 designs.

Technical Context

The MC68376BGVAB25 implements a 16-bit CPU32 core with 32-bit internal data paths and Harvard-style memory architecture. It integrates a 16-channel TPU for precise input capture/output compare and PWM generation, plus two independent CAN 2.0A/B controllers with message buffers and error handling logic.

Its memory subsystem includes 256 KB of mask-programmed ROM (version B), 8 KB of on-chip RAM, and external bus interface supporting 16-bit data/24-bit address expansion. The device uses a 160-pin LQFP package with dedicated analog supply pins (VDDA/VSSA), reference inputs (VRH/VRL), and crystal oscillator circuitry (XTAL/EXTAL).

Key Specifications

Pinout & Package

MC68376BGVAB25 is housed in a 160-pin Low-Profile Quad Flat Package (LQFP) per case 864A-03, measuring 31.0–31.4 mm square with 0.65 mm lead pitch and 3.35–3.85 mm body height. Pin 1 and pin 160 are No Connect (NC) to ensure pin compatibility with MC68336 Revision D+ devices.

Supply support for MC68376BGVAB25 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

NXP Semiconductors is a global semiconductor company formed from the spin-off of Philips' semiconductor division, now specializing in secure connectivity solutions for automotive, industrial, and IoT markets.

The MC68376 product line was developed by Motorola (acquired by Freescale, then NXP) to deliver deterministic real-time control for automotive powertrain and industrial motion systems using the proven CPU32 architecture.

FAQ

What is the ROM configuration of the MC68376BGVAB25?

The MC68376BGVAB25 contains 256 KB of mask-programmed ROM with version B firmware image. This ROM is factory-programmed during wafer fabrication and cannot be reprogrammed in-system. It provides non-volatile, tamper-resistant storage for boot code and application firmware, ensuring consistent behavior across all units shipped. The "B" suffix explicitly denotes this specific mask revision used in MC68376BGVAB25 production lots.

Does the MC68376BGVAB25 support CAN FD?

No, the MC68376BGVAB25 implements two CAN 2.0A/B controllers compliant with ISO 11898-1:2003, supporting data rates up to 1 Mbps and standard/extended frame formats. It does not support CAN FD features such as flexible data-rate switching, larger payload sizes, or CRC enhancements. For CAN FD capability, newer NXP S32K or MPC57xx families must be considered instead of the legacy MC68376BGVAB25 platform.

What is the significance of "GVAB25" in MC68376BGVAB25?

The suffix "GVAB25" in MC68376BGVAB25 decodes as follows: G = RoHS-compliant plastic package; V = −40 °C to +105 °C operating temperature grade; A = A-grade qualification test conditions; B = mask ROM version B; 25 = maximum operating frequency of 25 MHz. This full ordering code uniquely identifies the thermal, packaging, firmware, and speed configuration of the MC68376BGVAB25 device.

Can the MC68376BGVAB25 replace an MC68336 on the same PCB?

Yes, the MC68376BGVAB25 is pin-compatible with MC68336 Revision D and later devices: pins 1 and 160 are designated NC on both, and all signal assignments match per Figure B-2 in the Motorola User's Manual. However, the MC68376BGVAB25 adds CANRX0/CANTX0 pins (replacing unused MC68336 pins), so PCBs must either leave those pads unconnected or route them to a CAN transceiver. Firmware and peripheral initialization must also be updated to leverage the added CAN and TPU capabilities.

What clock sources does the MC68376BGVAB25 support?

The MC68376BGVAB25 supports crystal-based clocking via XTAL/EXTAL pins (4–25 MHz range), with internal PLL multiplication to achieve its 25 MHz core clock. It does not support external clock input or ceramic resonator operation. The PLL configuration is set by internal registers during reset, and the device requires stable crystal startup timing per Motorola specification - typical design practice uses a 16.000 MHz or 20.000 MHz fundamental-mode crystal to meet jitter and stability requirements for TPU and CAN timing accuracy.
