STMicroelectronics SPC58EG80E5PEC0X

Overview

SPC58EG80E5PEC0X from STMicroelectronics is a triple-core 32-bit Power Architecture e200z4 microcontroller designed for automotive ASIL-D safety-critical applications. It operates at up to 180 MHz, integrates 6144 KB code flash + 256 KB data flash, 608 KB general-purpose SRAM, and features dual PLLs, end-to-end ECC, lockstep CPU channel, and hardware security module (HSM). It is used in engine control units (ECUs) requiring ISO 26262 compliance.

For engineers reviewing the SPC58EG80E5PEC0X datasheet, SPC58EG80E5PEC0X pinout, SPC58EG80E5PEC0X application, or SPC58EG80E5PEC0X equivalent, key selection criteria include ASIL-D safety architecture validation, MCAN-FD interface count, HSM memory partitioning, and eTQFP144 thermal performance under 150 °C junction conditions.

Technical Context

The device implements a delayed lockstep safety architecture with one e200z4 core operating in lockstep with a checker core, supported by FCCU, MEMU, CRC unit, and logic/memory BIST. Its crossbar switch enables concurrent ECC-protected access to Flash, SRAM, and peripherals by multiple bus masters including two eDMA controllers (64+32 channels).

It integrates dual-phase locked loops: PLL0 provides stable clock domain for peripherals, while PLL1 supplies FM-modulated domain for computational shell timing. The HSM subsystem includes 144 KB dedicated code flash and 32 KB data flash, isolated for secure boot and cryptographic operations.

Key Specifications

Pinout & Package

FAQ

What is the maximum junction temperature rating for SPC58EG80E5PEC0X?

The device is rated for continuous operation at a junction temperature of -40 °C to +150 °C, validated per AEC-Q100 Grade 0 requirements. Thermal design must maintain θ_JA ≤ 32.5 °C/W using the eTQFP144 exposed pad and six-layer PCB layout with ≥4 thermal vias.

Does SPC58EG80E5PEC0X support AUTOSAR OS and MCAL?

Yes - ST provides certified AUTOSAR 4.3-compliant MCAL drivers (including CAN, ETH, SPI, ADC, ICU) and supports AUTOSAR OS 4.3 with pre-certified safety packages for ASIL-D applications, validated on SPC58EGx reference designs.

How is the Hardware Security Module (HSM) implemented in this device?

The HSM comprises a physically isolated RISC-V core with 144 KB dedicated code flash and 32 KB data flash, supporting AES-128/256, SHA-256, RSA-2048, and ECDSA. It handles secure boot, key provisioning, and cryptographic offload without exposing keys to the main CPU domain.

Can SPC58EG80E5PEC0X operate in a dual-clock domain configuration?

Yes - it integrates two independent PLLs: PLL0 generates clocks for peripherals and system infrastructure, while PLL1 supplies the FM-modulated computational shell clock. This enables independent frequency scaling and jitter suppression for safety-critical timing domains.
