Product details
Overview
SC68376BACAB25 from NXP Semiconductors (formerly Motorola) is a 16-bit microcontroller unit (MCU) featuring a CPU32 core, 20.97 MHz maximum clock frequency, 160-pin QFP package, integrated TPU (Time Processing Unit), and CAN 2.0A/B controller. It serves as a real-time control processor in industrial motion systems requiring deterministic I/O timing and fieldbus connectivity.
For engineers reviewing the SC68376BACAB25 datasheet, SC68376BACAB25 pinout, SC68376BACAB25 application, or SC68376BACAB25 equivalent, key selection criteria include TPU channel count (16-channel), CAN interface presence (dual CANRX0/CANTX0), ROM blank configuration, and extended temperature support (–40 to +125 °C).
Technical Context
The SC68376BACAB25 implements the CPU32 instruction set architecture with 32-bit internal data paths and 24-bit address bus, enabling direct access to up to 16 MB of external memory. It integrates a 16-channel Time Processing Unit for precise PWM generation, input capture, and output compare operations without CPU intervention.
It includes a full CAN 2.0A/B controller with dedicated CANRX0 and CANTX0 pins, supporting both standard and extended frame formats at up to 1 Mbps. The device uses a blank mask ROM (indicated by "B" in part number), allowing customer-specific firmware programming during production.

Pinout & Package
SC68376BACAB25 is housed in a 160-pin plastic quad flat pack (QFP), Case 864A-03, with 28.0 mm × 28.0 mm body size, 0.65 mm lead pitch, and 3.5 mm nominal height. Pin 1 is NC (no connect); pin 160 is VDD - ensuring pin compatibility with MC68336 Revision D+ devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connect - reserved for MC68336/376 family pin compatibility; must be left unconnected |
| 2 | CANRX0 | CAN controller receive input - connects directly to CAN transceiver RX line for message reception |
| 3 | CTM2C | TPU channel 2 input capture - used for edge-triggered timing event detection on external signals |
| 159 | CANTX0 | CAN controller transmit output - drives CAN transceiver TX line for differential bus transmission |
| 160 | VDD | Main supply voltage (5 V) - powers core logic, TPU, and CAN controller; requires local decoupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC68376BGCFT20 | Same CPU32 core and pinout, but rated for –40 to +85 °C and uses G-grade silicon | Suitable for commercial/industrial indoor applications only - not qualified for under-hood or high-ambient use | Select when cost sensitivity outweighs extended temperature requirement and CAN functionality remains essential |
| MC68336ACFT20 | Lacks CAN controller; identical TPU, CPU32, and package - but no CANRX0/CANTX0 pins | Applicable where fieldbus communication is handled externally or omitted entirely | Choose only if CAN is unnecessary and legacy design reuse of non-CAN firmware is required |
