NXP Semiconductors SC68376BGCAB25

Overview

SC68376BGCAB25 from Motorola is a 160-pin QFP 32-bit microcontroller featuring a 20.97 MHz CPU clock, integrated Time Processing Unit (TPU), and CAN 2.0A/B controller. It supports industrial temperature range (–40 to +85 °C), includes 16-channel analog-to-digital converter with 12-bit resolution, and executes real-time control in motor drive and automotive body electronics.

For engineers reviewing the SC68376BGCAB25 datasheet, SC68376BGCAB25 pinout, SC68376BGCAB25 application, or SC68376BGCAB25 equivalent, key selection criteria include TPU event timing precision, CAN message handling latency, ADC sampling rate under burst mode, and ROM mask compatibility for production firmware lock-in.

Technical Context

The SC68376BGCAB25 implements the MC68376 core architecture with a 32-bit CPU32+ instruction set, on-chip 8 KB RAM, and mask-programmed ROM. Its TPU provides independent 16-bit timer channels with input capture, output compare, and pulse-width modulation capabilities.

It integrates a full CAN 2.0A/B controller with 16 message objects, programmable bit timing, and automatic retransmission. The analog subsystem includes 16-channel 12-bit ADC with simultaneous sampling support and internal voltage reference (VRH/VRL).

FAQ

What is the maximum operating frequency of the SC68376BGCAB25?

The SC68376BGCAB25 operates at a maximum CPU clock frequency of 20.97 MHz, derived from an external crystal oscillator driving the on-chip PLL. This frequency sets the upper bound for instruction execution speed, TPU timing resolution, and ADC conversion rate. The SC68376BGCAB25 maintains full functionality-including CAN message handling and ADC sampling-at this rated speed across its specified temperature range.

Does the SC68376BGCAB25 include on-chip CAN controller hardware?

Yes, the SC68376BGCAB25 integrates a fully compliant CAN 2.0A/B controller with 16 message object buffers, programmable bit timing registers, and automatic retransmission logic. It requires only an external physical-layer transceiver (e.g., MC33290) to interface with a CAN bus. The SC68376BGCAB25's CAN module operates independently of the CPU core, allowing concurrent message processing and application execution.

What type of memory does the SC68376BGCAB25 use for program storage?

The SC68376BGCAB25 uses mask-programmed ROM for non-volatile program storage. This ROM is factory-configured during wafer fabrication and cannot be field-updated. The "B" in SC68376BGCAB25 indicates blank mask ROM, meaning firmware must be defined prior to ordering. The SC68376BGCAB25 does not include flash or EEPROM for runtime code modification.

How many analog input channels does the SC68376BGCAB25 support?

The SC68376BGCAB25 supports 16 analog input channels (AN0 through AN15), each configurable for single-ended or differential acquisition. These channels connect to a shared 12-bit successive-approximation ADC with internal voltage reference (VRH/VRL). The SC68376BGCAB25 allows sequential or burst-mode conversions with programmable sample-and-hold timing.

Is the SC68376BGCAB25 pin-compatible with the MC68336 series?

No, the SC68376BGCAB25 is not fully pin-compatible with the MC68336. While both use 160-pin QFP packages and share many signal names, the SC68376BGCAB25 adds dedicated CANRX0 and CANTX0 pins (replacing NC and RXD positions), and relocates several peripheral signals. Pin assignments differ between Figures B-1 (MC68336) and B-2 (MC68376) in the referenced manual. Board designs must be verified against the SC68376BGCAB25-specific pinout.
