Automotive Microcontrollers Gain Extended Lifespan as STMicroelectronics Commits to 20-Year SPC58 Availability

STMicroelectronics announced an extension of its longevity program for the SPC58 automotive microcontroller (MCU) family, increasing availability from 15 to 20 years. The seven product lines, targeting communication-gateway, powertrain, chassis, and body applications, will now be available until at least 2038, with the SPC58 H series, featuring up to 10MB non-volatile memory (NVM), guaranteed until 2041.

The SPC58 portfolio includes five general-purpose lines for smart gateways and body applications, such as lighting and door locking, equipped with communication, analog, and security peripherals. The high-performance SPC58 E and SPC58 N lines target powertrain-electrification and chassis-safety applications, offering features like multiple timers and FlexPWM for complex motor-control tasks. These high-performance lines support systems aiming for ISO 26262 ASIL-D, the highest safety-integrity level, while other lines support ASIL-B certification.

The family comprises over 40 variants, ranging from the compact 10mm x 10mm eTQFP64 SPC58 2B to the 19mm x 19mm FPBGA386 SPC58 H. The MCUs, built on STMicroelectronics’ 40nm embedded flash process, feature up to three e200z4 32-bit Power Architecture® cores and 1MB to 10MB on-ch...
