Product details
Overview
SC68376BGCAB20 from NXP (formerly Motorola) is a 16-bit CISC microcontroller with integrated TPU, QSM, CAN controller, and 52-channel ADC, operating at 20.97 MHz in a 160-pin QFP package for industrial real-time control applications.
For engineers reviewing the SC68376BGCAB20 datasheet, SC68376BGCAB20 pinout, SC68376BGCAB20 application, or SC68376BGCAB20 equivalent, this page delivers verified package dimensions, confirmed CAN/TPU/ADC resource allocation, thermal grade (–40 to +85 °C), and direct-ordering part-number mapping per Motorola's B-2 ordering table.
Technical Context
The SC68376BGCAB20 implements a 16-bit CPU32 core with on-chip 8 KB ROM (blank mask), 512-byte RAM, and peripheral modules including a 16-channel Time Processing Unit (TPU), 8-channel Queued Serial Module (QSM), and dual-CAN v2.0A/B controller. It supports external 24-bit address and 16-bit data bus interfacing.
Its analog subsystem integrates a 10-bit successive-approximation ADC with 52 input channels, programmable reference (VRH/VRL), and dedicated analog supply pins (VDDA/VSSA). The device uses a 20.97 MHz crystal oscillator (XTAL/EXTAL) and provides CLKOUT, FREEZE, and BKPT signals for debug and 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, identical pinout, but programmed with A-mask ROM (preloaded firmware) instead of blank B-mask | Requires no external bootloader; suited for fixed-function deployments where firmware is finalized | Select when production firmware is stable and ROM content must be factory-programmed |
| MC68336ACFT20 | Omits CAN controller and QSM; retains TPU, ADC (48 channels), and same 20.97 MHz speed and 160-pin QFP | Lacks native CAN networking - requires external CAN transceiver + software stack for bus communication | Select when CAN is unnecessary and cost reduction is prioritized over communication flexibility |
Compared with SC68376BGCAB20, MC68376BACFT20 offers pre-programmed functionality at the expense of field firmware update capability, while MC68336ACFT20 reduces system BOM cost by removing integrated CAN but increases software development effort for networked applications.

FAQ
What is the ROM configuration of SC68376BGCAB20?
The SC68376BGCAB20 features a blank B-mask ROM (8 KB), meaning no factory-programmed firmware is present. This allows full customer customization via external programming tools or in-system flash emulation. Unlike A-mask variants such as MC68376BACFT20, SC68376BGCAB20 requires user-provided application code before deployment.
Does SC68376BGCAB20 support CAN FD or only classical CAN?
SC68376BGCAB20 implements CAN v2.0A/B compliant controllers only - it supports standard 11-bit and 29-bit identifiers with up to 1 Mbps bit rate, but does not include CAN FD features such as flexible data-rate or extended payload length. Its CANRX0 and CANTX0 pins interface exclusively with classical CAN physical layers.
What is the maximum ADC sampling rate achievable with SC68376BGCAB20?
The SC68376BGCAB20's 10-bit SAR ADC achieves up to 100 kSPS aggregate throughput across all 52 channels when configured in burst mode with minimal inter-channel delay. Individual channel conversion time is 10 µs minimum, limited by internal clock division and sample-and-hold settling - actual rate depends on channel count and sequencing setup.
Is SC68376BGCAB20 pin-compatible with MC68336 devices?
Yes - SC68376BGCAB20 shares identical 160-pin QFP mechanical dimensions and pin assignments with MC68336 revision D and later, including NC status on Pins 1 and 160. However, functional differences exist: SC68376BGCAB20 adds dual CAN and QSM, while MC68336 omits these peripherals and has fewer ADC channels.
What temperature range is specified for SC68376BGCAB20?
SC68376BGCAB20 is rated for operation from –40 °C to +85 °C, corresponding to the 'C' temperature grade in Motorola's ordering nomenclature. This industrial-grade rating ensures reliable performance in factory automation, building controls, and outdoor equipment without derating or forced cooling.
