Product details
Overview
SPC58EC74E7P000X from STMicroelectronics is an AEC-Q100 qualified 32-bit Power Architecture automotive microcontroller with dual e200z420n3 cores operating at up to 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 supports CAN-FD, FlexRay, and 10/100 Mbps Ethernet for powertrain and chassis control systems.
For engineers reviewing the SPC58EC74E7P000X datasheet, SPC58EC74E7P000X pinout, SPC58EC74E7P000X application, or SPC58EC74E7P000X equivalent, this MCU delivers deterministic real-time performance, hardware-accelerated cryptographic operations via HSM, and end-to-end ECC across crossbar-switched memory/peripheral access - critical for ASIL-B automotive ECU design, firmware-over-the-air (FOTA) security, and time-sensitive sensor-actuator coordination.
Technical Context
The SPC58EC74E7P000X implements a dual-core lock-step-capable architecture with delayed lock-step redundancy checkers and dedicated Memory Error Management Unit (MEMU) for error detection in flash and SRAM. Its crossbar switch enables concurrent bus master access to peripherals, Flash, and RAM with end-to-end ECC protection on all paths.
It features two independent phase-locked loops: PLL0 provides stable clock domains for peripherals and communication interfaces (CAN-FD, LINFlexD, DSPI), while PLL1 supplies the FM modulation domain for computational shell timing. The BCTU synchronizes ADC conversions with eMIOS PWM outputs or PIT_RTI timers to eliminate sampling jitter in motor control feedback loops.

FAQ
What is the maximum junction temperature rating for SPC58EC74E7P000X?
The SPC58EC74E7P000X is rated for a junction temperature range of –40 °C to +150 °C, validated per AEC-Q100 Grade 0 requirements. This enables deployment in under-hood environments such as EPS motor control modules and brake caliper ECUs where ambient temperatures exceed 125 °C.
Does SPC58EC74E7P000X support CAN FD with bit rate switching?
Yes, all eight MCAN interfaces comply with ISO 11898-1:2015 CAN FD, supporting bit rate switching (up to 5 Mbps data phase) and flexible payload lengths (up to 64 bytes). Each MCAN includes shared memory scheme and hardware message filtering to reduce CPU load in high-bandwidth networks.
How is the Hardware Security Module (HSM) isolated from the main cores?
The HSM is physically isolated with dedicated 176 KB flash (144 KB code + 32 KB data), separate bus interface, and no software-accessible pathways from the main e200z420 cores. It executes only signed, encrypted firmware loaded during secure boot and provides cryptographic services via mailbox interface with strict access control.
Can SPC58EC74E7P000X operate in ultra-low-power standby mode with RTC active?
Yes, the Smart Standby mode maintains RTC accuracy and retains SRAM content while drawing less than 100 µA from VDD_LV. Wake-up is supported via SIUL2 pins, BCTU events, or LIN/CAN bus activity - enabling always-on network presence without compromising battery life in parked vehicle scenarios.
