NXP Semiconductors SC68376BGMAB20

Overview

SC68376BGMAB20 from NXP (formerly Motorola) is a 16-bit microcontroller unit (MCU) featuring a CPU32 core, 20.97 MHz operation, integrated Time Processing Unit (TPU), and CAN 2.0A/B controller. It implements a 160-pin QFP package with mixed-signal I/O, on-chip ROM, and supports industrial temperature range (–40 to +125 °C). It is used in real-time engine control and embedded motion systems requiring deterministic timing and serial bus coordination.

For engineers reviewing the SC68376BGMAB20 datasheet, SC68376BGMAB20 pinout, SC68376BGMAB20 application, or SC68376BGMAB20 equivalent, key selection criteria include TPU channel count, CAN interface presence, ROM blank status, temperature grade, and QFP-160 mechanical compatibility with legacy MC68336/376 designs.

Technical Context

The SC68376BGMAB20 integrates the CPU32 16-bit core with a 20.97 MHz maximum clock frequency, supporting instruction execution at up to 10.5 MIPS. Its TPU provides 24 independent channels for precise input capture, output compare, and pulse-width modulation-critical for motor phase timing and sensor event synchronization.

It includes a full CAN 2.0A/B controller with dedicated CANRX0 and CANTX0 pins, enabling robust automotive and industrial fieldbus communication. The device features 16-bit address/data multiplexed bus (ADDR0–ADDR23, DATA0–DATA15), analog inputs (AN0–AN59), and dual power domains (VDDA/VSSA for analog, VDD/VSS for digital).

Key Specifications

Pinout & Package

SC68376BGMAB20 uses a 160-pin plastic quad flat pack (QFP), Case 864A-03, with 0.65 mm lead pitch, 28.0 mm × 28.0 mm body size, and 3.5 mm max height per JEDEC MS-026. Pin 1 and Pin 160 are No Connect (NC) to ensure pin compatibility with MC68336 Revision D+ devices.

FAQ

What is the core architecture of the SC68376BGMAB20?

The SC68376BGMAB20 features the CPU32 16-bit RISC core, derived from the Motorola 68000 architecture. It executes instructions at up to 10.5 MIPS at 20.97 MHz, supports 32-bit internal data paths, and delivers deterministic interrupt latency essential for hard real-time control. This core is fully documented in the MC68376 User's Manual and forms the foundation of all SC68376BGMAB20 firmware development.

Does the SC68376BGMAB20 include an integrated CAN controller?

Yes, the SC68376BGMAB20 includes a full CAN 2.0A/B controller with dedicated CANRX0 (Pin 1) and CANTX0 (Pin 109) pins. It supports standard and extended identifiers, message filtering, and error handling per ISO 11898. No external CAN protocol IC is required - only a physical-layer transceiver is needed for bus connection.

What does the "B" and "G" in SC68376BGMAB20 signify?

In SC68376BGMAB20, "B" indicates blank mask ROM (no factory firmware), "G" denotes the industrial-grade temperature range (–40 to +125 °C), and "M" specifies the 160-pin QFP package. The "AB20" suffix confirms 20.97 MHz maximum frequency and A-grade TPU configuration. These codes align with Motorola's official ordering nomenclature in Table B-2 of the MC68336/376 User's Manual.

Is the SC68376BGMAB20 pin-compatible with the MC68336 series?

Yes - SC68376BGMAB20 is pin-compatible with MC68336 Revision D and later devices. Pins 1 and 160 are designated NC on both, ensuring mechanical and layout compatibility. However, SC68376BGMAB20 adds CANRX0 and CANTX0 functionality absent in MC68336, so firmware and schematic must account for those dedicated signals.

What analog resources does the SC68376BGMAB20 provide?

The SC68376BGMAB20 integrates a 60-channel 10-bit ADC with dedicated analog supply pins (VDDA/VSSA) and programmable reference inputs (VRH/VRL). Channels AN0–AN59 support simultaneous sampling control via TPU triggers, enabling synchronized acquisition of engine sensor data such as throttle position, coolant temperature, and oxygen sensor voltage.
