32-bit Power Architecture automotive MCU, 64 MHz e200z0h, 512 KB flash, LQFP144, -40 °C to +125 °C – ST SPC560B50 B-revision silicon
The STMicroelectronics SPC560B50L5B6E0X is an automotive-grade 32-bit microcontroller from the SPC56 B line, built around a 64 MHz e200z0h Power Architecture core with 512 KB of ECC code flash, 64 KB data flash and 48 KB SRAM, in a 144-pin LQFP rated for -40 °C to +125 °C. With up to six FlexCAN, four LINFlex/UART, three DSPI and a 36-channel 10-bit ADC, it is a typical body-electronics and gateway controller in door modules, lighting, HVAC and body control modules. The B6E0X code denotes the B silicon revision; ST now lists only the C revision as the active orderable part, so automotive Tier-1 and aftermarket programs that validated software and PPAP on revision B are sourcing remaining stock on the open market. Cerametronics sources SPC560B50L5B6E0X with date code and traceability and quotes within 24 hours.

Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
What is the difference between SPC560B50L5B6E0X and SPC560B50L5C6E0X?
They are the same SPC560B50 MCU in LQFP144; the letter after L5 is the silicon revision. ST's product page now lists only the C revision as active, so programs locked to the B revision (validated software, automotive PPAP documentation) source remaining B-revision stock from the channel and the open market.
Is the SPC560B50 family itself being discontinued?
No. ST shows the SPC560B50L5 family as active with longevity commitment through 2034. The shortage is specific to the B silicon revision orderable code and to lead times on the automotive-grade LQFP144 parts.
