Product details
Overview
SPC58EC80E7G0C0X 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), Hardware Security Module (HSM), and ASIL-B functional safety compliance per ISO 26262. It integrates 384 KB general-purpose SRAM, 8 MCAN interfaces with ISO CAN-FD support, 10/100 Mbps Ethernet with IEEE 1588 time stamping, and dual PLLs for independent peripheral and computational clock domains - deployed in engine control units and advanced driver assistance systems (ADAS) domain controllers.
For engineers reviewing the SPC58EC80E7G0C0X datasheet, SPC58EC80E7G0C0X pinout, SPC58EC80E7G0C0X application, or SPC58EC80E7G0C0X equivalent, key selection criteria include dual-core lock-step readiness for ASIL-B, HSM-secured boot and cryptographic acceleration, CAN-FD/Ethernet coexistence for zonal gateway designs, and eLQFP176 package compatibility with automotive PCB thermal and mechanical constraints.
Technical Context
The SPC58EC80E7G0C0X implements a dual-core delayed lock-step (DLS) architecture with redundancy checkers per core, enabling real-time fault detection for ASIL-B compliance. Its crossbar switch (XBAR) supports concurrent ECC-protected access to Flash, SRAM, and peripherals by up to six bus masters, including two CPU cores, eDMA, and HSM.
It features a dedicated Hardware Security Module (HSM) with 176 KB flash (144 KB code + 32 KB data), supporting secure boot, AES-128/256, SHA-256, and RSA-2048 operations. Clocking includes dual PLLs: PLL0 for stable peripheral domain timing and PLL1 for FM-modulated computational shell operation - decoupling timing-critical I/O from high-throughput compute tasks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | ARM Cortex-M7 dual-core, 2 MB flash, no integrated Ethernet MAC, uses external PHY; supports ASIL-D via lock-step + ECC. | Lacks native 10/100 Mbps Ethernet with IEEE 1588 - requires external PHY and additional PCB area for time-sync circuitry. | Select when ARM ecosystem tooling and ASIL-D certification path are mandatory, and Ethernet is routed externally. |
| Renesas RH850/U2A | 32-bit RXv3 core, 4 MB flash, 12 CAN FD, no HSM - relies on external security chip; supports ASIL-B via software-implemented diagnostics. | No on-die cryptographic accelerator - increases BOM cost and software validation burden for secure boot and OTA. | Select when legacy RH850 toolchain compatibility and CAN FD channel count >8 are primary drivers over integrated security. |

FAQ
What is the maximum junction temperature rating for SPC58EC80E7G0C0X?
The SPC58EC80E7G0C0X is rated for a junction temperature range of –40 °C to +150 °C, validated per AEC-Q100 Grade 0 stress testing. This enables deployment in under-hood environments such as engine control modules without active cooling, provided PCB thermal design meets ST's recommended copper pour and via guidelines in AN5027.
Does SPC58EC80E7G0C0X support CAN FD with data rates above 2 Mbps?
Yes - all eight MCAN modules support ISO 11898-1:2015 CAN FD, with arbitration bit rates up to 1 Mbps and data phase bit rates up to 5 Mbps. The device includes shared memory schemes and flexible message RAM configuration to handle mixed legacy CAN and CAN FD traffic simultaneously without CPU intervention.
How is the Hardware Security Module (HSM) isolated from the main application cores?
The HSM is implemented as a physically separate subsystem with its own 176 KB flash, 32 KB data RAM, dedicated bus interface, and independent power domain (HSM_VDD/HSM_VSS). It runs certified secure firmware and enforces strict memory protection via the System MPU, preventing unauthorized access from main cores even during runtime privilege escalation attempts.
Can SPC58EC80E7G0C0X operate in ultra-low-power standby mode with RTC and wake-up capability?
Yes - it supports Smart Standby mode with RTC running on VBAT, consuming <5 µA typical. Wake-up sources include LIN/CAN messages, GPIO interrupts, BCTU-triggered ADC events, and periodic PIT alarms. The 10-bit STDBY-mode ADC remains operational during standby, enabling continuous battery cell monitoring without full MCU wake-up.
