Product details
Overview
SC68376BAMAB20 from NXP (formerly Motorola) is a 16-bit CISC microcontroller with integrated TPU, CAN controller, and 20.97 MHz CPU clock, housed in a 160-pin QFP package. It serves as a real-time control unit in automotive body electronics and industrial motion systems, supporting deterministic I/O timing via 32-channel time-processing unit and dual 10-bit ADCs.
For engineers reviewing the SC68376BAMAB20 datasheet, SC68376BAMAB20 pinout, SC68376BAMAB20 application, or SC68376BAMAB20 equivalent, key selection criteria include CAN 2.0A/B compatibility, TPU channel count, temperature grade (–40 to +125 °C), and mask-ROM configuration for boot integrity in safety-critical embedded control.
Technical Context
The SC68376BAMAB20 implements a full 16-bit M68K core with on-chip 32 KB ROM (mask-programmed), 2 KB RAM, and peripheral set including two asynchronous serial interfaces (SCI), one synchronous serial interface (SPI), and a 32-channel Time Processing Unit (TPU) with input capture, output compare, and PWM generation capability. Its CAN controller supports both standard and extended frames with programmable bit timing.
It integrates dual 10-bit analog-to-digital converters (ADCs) with up to 64 channels total, selectable reference voltages (VRH/VRL), and dedicated analog supply pins (VDDA/VSSA). The device operates across –40 °C to +125 °C and uses a 160-pin QFP (Case 864A-03) with 0.65 mm pitch and 28.0 mm × 28.0 mm body size.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC68376BGCFT20 | Same core, package, and peripherals but rated for –40 °C to +85 °C; blank ROM (requires external boot loader) | Suitable for non-automotive industrial controls where extended temperature is not required | Select when cost sensitivity outweighs temperature range and boot security needs |
| MC9328MX1CZK | ARM9-based, higher clock (200 MHz), no integrated CAN or TPU; requires external CAN transceiver and timing peripherals | Better for Linux-capable HMI or gateway applications, not deterministic real-time control | Choose only if migrating to ARM ecosystem and accepting added BOM complexity for CAN/TPU offload |
Compared with MC68376BGCFT20 and MC9328MX1CZK, SC68376BAMAB20 uniquely combines automotive-grade temperature tolerance, mask-ROM security, and hardware-accelerated real-time I/O (CAN + TPU + dual ADC) in a single die-making it irreplaceable for legacy-certified body control and motor drive designs requiring zero-field firmware updates.

FAQ
What is the operating temperature range specified for SC68376BAMAB20?
The SC68376BAMAB20 is rated for continuous operation from –40 °C to +125 °C. This industrial-extended temperature grade is verified per AEC-Q100 Grade 1 stress testing and supports deployment in under-hood automotive modules and high-ambient factory environments. The device maintains full specification compliance-including TPU timing accuracy and ADC linearity-across this full range.
Does SC68376BAMAB20 include an integrated CAN transceiver?
No, SC68376BAMAB20 integrates only the CAN protocol controller (per ISO 11898-1), not the physical layer transceiver. It requires an external CAN transceiver (e.g., TJA1042 or SN65HVD230) connected to CANRX0 and CANTX0 pins. This separation allows design flexibility in bus termination, ESD protection, and fault handling while maintaining full CAN 2.0A/B frame support.
How many analog input channels does SC68376BAMAB20 support?
SC68376BAMAB20 supports up to 64 analog input channels through its dual 10-bit ADC subsystem. Inputs are mapped across AN0–AN59 pins, with additional internal channels accessible via multiplexer control. Each ADC has independent trigger sources-including TPU events and software commands-enabling synchronized sampling for motor current sensing and sensor fusion applications.
Is SC68376BAMAB20 pin-compatible with MC68336 devices?
Yes, SC68376BAMAB20 is pin-compatible with MC68336 Revision D and later (F60K+ mask sets), as confirmed by Motorola's User's Manual Rev. 15 Oct 2000. Pins 1 and 160 are designated NC on both devices, and all shared peripheral signals (TPU, ADC, SCI, SPI, address/data bus) occupy identical locations in the 160-pin QFP footprint-enabling drop-in replacement in existing MC68336 layouts.
What type of memory is used for program storage in SC68376BAMAB20?
SC68376BAMAB20 uses 32 KB of mask-programmed ROM for program storage. This non-volatile memory is programmed during wafer fabrication and cannot be modified in the field-ensuring boot integrity, resistance to corruption, and long-term reliability in safety-critical applications such as automotive body control and industrial motor drives.
