Product details
Overview
SPC58EC74E7P001X 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, 8 MCAN interfaces with ISO CAN-FD support, and a 10/100 Mbps Ethernet MAC with IEEE 1588 time stamping - deployed in engine control units for real-time combustion management and diagnostics.
For engineers reviewing the SPC58EC74E7P001X datasheet, SPC58EC74E7P001X pinout, SPC58EC74E7P001X application, or SPC58EC74E7P001X equivalent, key selection criteria include dual-core lock-step capability, HSM cryptographic acceleration, ASIL-B safety architecture (FCCU, MEMU, CRC), and multi-protocol connectivity (CAN-FD, FlexRay, Ethernet) for domain controller consolidation.
Technical Context
The SPC58EC74E7P001X implements a dual-core delayed lock-step (DLS) architecture with redundancy checkers for CPU-level fault detection, paired with a dedicated HSM containing 176 KB flash (144 KB code + 32 KB data) and hardware cryptographic accelerators. Its crossbar switch enables concurrent ECC-protected access to Flash, SRAM, and peripherals by multiple bus masters including CPU cores, eDMA, and Ethernet MAC.
Timing is governed by dual PLLs: PLL0 provides stable clock domains for peripherals and system logic, while PLL1 delivers FM-modulated clocks for computational shell operations. The device supports full read-while-write (RWW) flash operation across multiple partitions, enabling EEPROM emulation and safe over-the-air (OTA) firmware updates without runtime interruption.

FAQ
What is the maximum junction temperature rating for SPC58EC74E7P001X?
The SPC58EC74E7P001X is rated for a junction temperature range of –40 °C to +150 °C, validated per AEC-Q100 Grade 0 requirements. This specification enables direct mounting in under-hood environments without forced cooling, supporting continuous operation in gasoline and diesel engine control applications where ambient temperatures exceed 125 °C.
Does SPC58EC74E7P001X support IEEE 1588 Precision Time Protocol (PTP)?
Yes, the integrated Ethernet MAC supports IEEE 1588-2008 with a 64-bit hardware time stamp unit, enabling sub-microsecond timestamp accuracy on ingress/egress frames. This capability is essential for time-synchronized sensor fusion in domain controllers and meets AUTOSAR Adaptive Platform timing requirements for distributed systems.
How is the Hardware Security Module (HSM) isolated from the main application cores?
The HSM is physically isolated with dedicated 176 KB flash (144 KB code + 32 KB data), separate power domain (HSM_VDD/HSM_VSS), and independent bus interface. It executes secure boot, AES-128/256, SHA-256, and RSA-2048 operations without exposing keys or intermediate values to the main e200z420n3 cores, satisfying EVITA Medium and UNECE WP.29 CSMS requirements.
Can SPC58EC74E7P001X perform read-while-write (RWW) on flash memory during runtime?
Yes, the 4096 KB code flash supports true RWW operation across multiple independently erasable blocks. This allows background firmware updates and calibration table writes without halting CPU execution - critical for seamless over-the-air (OTA) updates in production vehicles while maintaining real-time engine control loop integrity.
