Product details
Overview
SPC58EC80E3G0C1X from STMicroelectronics is an AEC-Q100 qualified 32-bit Power Architecture automotive microcontroller featuring dual e200z420n3 cores at 180 MHz, 4 MB on-chip flash (4096 KB code + 128 KB data), 384 KB general-purpose SRAM, and integrated Hardware Security Module (HSM) supporting ASIL-B compliance per ISO 26262. It targets engine control units (ECUs), transmission control modules, and advanced driver assistance systems (ADAS) domain controllers requiring functional safety and real-time deterministic execution.
For engineers reviewing the SPC58EC80E3G0C1X datasheet, SPC58EC80E3G0C1X pinout, SPC58EC80E3G0C1X application, or SPC58EC80E3G0C1X equivalent, key selection criteria include dual-core lock-step capability, ISO CAN-FD support across eight MCAN interfaces, IEEE 802.3-2008 Ethernet with AVB/TSN readiness, and HSM-based cryptographic acceleration for secure boot and firmware updates.
Technical Context
The SPC58EC80E3G0C1X implements a dual-core delayed lock-step (DLS) architecture with redundancy checkers for ASIL-B safety-critical tasks, paired with a dedicated HSM containing 176 KB flash (144 KB code + 32 KB data) and hardware crypto accelerators. Its crossbar switch enables concurrent ECC-protected access to Flash, SRAM, and peripherals by multiple bus masters including eDMA, CPU cores, and Ethernet MAC.
Timing subsystems include dual PLLs-one for peripheral clock domains and one for FM-modulated computational shell-plus three oscillators (40 MHz crystal, 32 kHz crystal, and 16 MHz RC). The ADC system comprises three independent 12-bit SAR converters, one supervisor 12-bit SAR, and one 10-bit SAR with STDBY mode, all synchronized via BCTU triggers from eMIOS or PIT_RTIs.

FAQ
What is the maximum junction temperature rating for SPC58EC80E3G0C1X?
The SPC58EC80E3G0C1X is rated for a junction temperature range of –40 °C to +150 °C, meeting AEC-Q100 Grade 1 requirements. This specification is validated across all operating modes-including full-speed dual-core execution with active Ethernet and MCAN traffic-and confirmed in DS11620 Rev 8 Section 4.6.
Does SPC58EC80E3G0C1X support IEEE 1588 Precision Time Protocol?
Yes, the integrated Ethernet MAC supports IEEE 1588-2008 timestamping with internal 64-bit time stamp counter, hardware timestamp insertion on transmit, and capture on receive. It delivers sub-100 ns timestamp accuracy when used with compatible PHYs and calibrated system clocks, as specified in DS11620 Rev 8 Section 4.17.3.
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 bus interface, and independent clock domain. It runs certified secure boot firmware and performs AES-128/256, SHA-256, and RSA-2048 operations without exposing keys to main cores-verified in ST's SPC58 HSM Security Manual UM2282.
Can SPC58EC80E3G0C1X operate in ultra-low-power standby mode with RTC active?
Yes, it supports Smart Standby mode with active RTC, wake-up on LIN/CAN activity, and configurable I/O pin monitoring-all while drawing less than 100 µA.
