Product details
Overview
SPC58EC74E3E0C0X from STMicroelectronics is an AEC-Q100 qualified 32-bit Power Architecture automotive microcontroller with dual e200z420n3 cores running at 180 MHz, 4 MB on-chip flash (4096 KB code + 128 KB data), Hardware Security Module (HSM), and ASIL-B functional safety compliance per ISO 26262. It integrates 384 KB general-purpose SRAM, 64-channel eDMA, dual PLLs, and 8 MCAN interfaces supporting ISO CAN-FD for engine control unit (ECU) applications.
For engineers reviewing the SPC58EC74E3E0C0X datasheet, SPC58EC74E3E0C0X pinout, SPC58EC74E3E0C0X application, or SPC58EC74E3E0C0X equivalent, key selection criteria include dual-core lock-step capability, HSM cryptographic acceleration, 180 MHz real-time deterministic execution, and integrated FlexRay/Ethernet/ADC subsystems for automotive domain controllers.
Technical Context
The SPC58EC74E3E0C0X implements a delayed lock-step architecture with redundancy checkers across both e200z420n3 cores, enabling ASIL-B fault detection and recovery. Its crossbar switch (XBAR) supports concurrent ECC-protected access to Flash, SRAM, and peripherals by multiple bus masters including CPU, DMA, and HSM.
It features two independent PLL domains: PLL0 provides stable clocking for peripherals and system logic, while PLL1 delivers FM-modulated clocks for computational shell timing. The HSM contains dedicated 176 KB flash (144 KB code + 32 KB data) and hardware cryptographic accelerators compliant with AUTOSAR SecOC requirements.

FAQ
What is the maximum junction temperature rating for SPC58EC74E3E0C0X?
The SPC58EC74E3E0C0X is rated for a junction temperature range of –40 °C to +150 °C, validated per AEC-Q100 Grade 1 requirements. This enables deployment in under-hood environments such as engine control modules and transmission control units where ambient temperatures exceed 125 °C.
Does SPC58EC74E3E0C0X support AUTOSAR OS and MCAL drivers?
Yes, STMicroelectronics provides full AUTOSAR 4.3–4.4 compliant MCAL drivers and OS support for the SPC58EC74E3E0C0X, including CAN FD, Ethernet, ADC, eMIOS, and HSM modules. These are validated with leading AUTOSAR integrators and distributed via ST's SPC5 Studio development suite.
How is the Hardware Security Module (HSM) isolated from the main CPU cores?
The HSM is physically isolated with its own 176 KB flash, 32 KB data RAM, dedicated bus interface, and separate power domain. It runs a secure real-time OS and enforces strict memory protection via its own MPU, preventing unauthorized access to cryptographic keys or secure boot code-even if the main cores are compromised.
Can SPC58EC74E3E0C0X operate in ultra-low-power standby mode with RTC active?
Yes, the device supports Smart Standby mode with active RTC and configurable wake-up sources (analog comparators, digital pins, timer alarms). Typical current consumption in this mode is below 10 µA, enabling always-on vehicle functions like intrusion detection and remote keyless entry without draining the battery.
