FAQ
What is the ROM configuration of SC68376BAVAB25?
The SC68376BAVAB25 features 32 KB of factory-masked ROM (BACFT20 variant), programmed during wafer fabrication. This eliminates external boot memory, improves startup reliability, and prevents runtime firmware corruption. The ROM contains the primary application code and bootloader, and cannot be reprogrammed in-system.
Does SC68376BAVAB25 support CAN FD?
No, SC68376BAVAB25 implements CAN 2.0A/B protocol only, supporting standard (11-bit) and extended (29-bit) identifier frames at up to 1 Mbit/s. It does not support CAN FD features such as flexible data-rate or increased payload length. For CAN FD, consider newer NXP SPC5 or MPC5xxx families.
What is the function of pins TPUCH0 through TPUCH15 on SC68376BAVAB25?
TPUCH0–TPUCH15 (pins 11–26) are dedicated I/O terminals for the 16-channel Time Processing Unit. Each pin supports configurable input capture, output compare, PWM generation, and quadrature decoding-enabling precise, hardware-timed control of motors, encoders, and ignition systems without CPU intervention.
Is SC68376BAVAB25 pin-compatible with MC68336 devices?
Yes, SC68376BAVAB25 is pin-compatible with MC68336 in the 160-pin QFP package. Pin 1 (CANRX0) and pin 159 (CANTX0) replace the MC68336's NC and RXD/TXD functions respectively, while all other signal assignments-including address/data bus, TPU, ADC, and power pins-match identically per Figures B-1 and B-2.
What temperature range is validated for SC68376BAVAB25?
SC68376BAVAB25 is qualified for industrial operation from –40 °C to +105 °C (AV grade). This range is verified per AEC-Q100 stress testing and supports under-hood automotive applications, industrial drives, and outdoor-rated control systems where ambient thermal extremes are expected.
