September 10, 2025 /SemiMedia/ — STMicroelectronics said it has extended the longevity program for its SPC58 automotive microcontrollers from 15 years to 20 years, ensuring supply of general-purpose and high-performance product lines until at least 2038. The SPC58 H series, featuring up to 10MB of non-volatile memory, will be supported until 2041.

The SPC58 family targets a wide range of automotive applications, from smart gateways and body electronics to powertrain electrification and chassis safety. General-purpose lines support functions such as lighting and door locking, while high-performance versions including SPC58 E and N offer advanced features like multiple timer options and FlexPWM modules for motor-control systems.

ST said the extension reflects its long-term commitment to automakers and system designers, allowing customers to maintain successful products and plan new projects with confidence. Several SPC58 variants are designed for functional-safety compliance, supporting ISO 26262 standards from ASIL-B up to ASIL-D.

The family includes more than 40 device variants, manufactured on ST’s 40nm embedded flash process and packaged from compact 10mm x 10mm eTQFP64 to larger 19mm x 19mm FPBGA386. ST emphasized that its in-house manufacturing model ensures full control over design, production and long-term support.
