SPC5 General Purpose MCUs

Our portfolio of general-purpose SPC5 automotive microcontrollers addresses a wide range of applications requiring low-power, connectivity and security.

These Power Architecture® MCUs are integrated in body applications such as gateways, body control modules, and convenience, secure keyless car access as well as in car electrification applications such as battery management units.

SPC5 general-purpose MCUs are ASIL-B and ASIL-D compliant. Moreover, they integrate sophisticated power management features including Halt, Stop and Standby modes to reduce system power consumption.

General-purpose SPC5 automotive MCUs include standard SPC56 (Bolero series) microcontrollers and SPC58 (Chorus series) microcontrollers with additional connectivity and security features.

SPC58 Chorus is developed to deliver 3 concepts: Connected, Secure, and Scalable:


A wide range of communication interfaces makes ST's SPC5 automotive MCUs an ideal solution to enable gateway functionalities within any application.


Several levels of security are available depending on application requirements: from software to EVITA-compliant automotive hardware security levels (light, medium, and full).

Certain devices include a Cryptographic Services Engine (CSE) featuring AES-128 encryption/decryption, CMAC authentication and secured device boot mode.


The SPC5 family's unique scalability makes it an ideal solution for long-term platform development strategies. In particular, the SPC58 Chorus series lets you select multiple microcontrollers for the same board thanks to their pin-to-pin compatibility across the same package.
