STMicroelectronics SPC58EC80E7FMC0X

Overview

SPC58EC80E7FMC0X 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, 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 and ADAS domain controllers.

For engineers reviewing the SPC58EC80E7FMC0X datasheet, SPC58EC80E7FMC0X pinout, SPC58EC80E7FMC0X application, or SPC58EC80E7FMC0X equivalent, key selection criteria include dual-core lock-step readiness for ASIL-B, HSM cryptographic acceleration, CAN-FD message RAM allocation, eTQFP176 package thermal performance, and Flash RWW capability for over-the-air firmware updates.

Technical Context

The SPC58EC80E7FMC0X implements a dual-core delayed lock-step (DLS) architecture with redundancy checkers for fault detection, coupled with a dedicated Hardware Security Module containing 176 KB flash (144 KB code + 32 KB data) and cryptographic co-processing logic. 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 subsystems include dual PLLs: one for stable peripheral clock domains and another for FM-modulated computational shell operation; the BCTU synchronizes ADC conversions with up to 64 eMIOS channels or two PIT_RTIs, while the enhanced SAR ADC system comprises three independent 12-bit converters, one supervisor 12-bit converter, and one 10-bit converter with STDBY mode support.

Key Specifications

Pinout & Package

eLQFP176 package (24 mm × 24 mm × 1.4 mm body, 0.5 mm pitch), thermally enhanced with exposed thermal pad, rated for automotive AEC-Q100 Grade 0 (–40 °C to +150 °C TJ).

FAQ

What is the maximum operating junction temperature for SPC58EC80E7FMC0X?

The SPC58EC80E7FMC0X is rated for a junction temperature range of –40 °C to +150 °C, validated per AEC-Q100 Grade 0 requirements. This rating applies under specified voltage, current, and thermal resistance conditions defined in Section 4.6 of the DS11620 datasheet, and must be verified against actual board-level thermal design using the θ_JA = 22.5 °C/W value for eLQFP176 packages.

Does SPC58EC80E7FMC0X support bootloading over CAN-FD?

No - the Boot Assist Flash (BAF) supports serial bootloading only over asynchronous CAN (Classical CAN, up to 1 Mbps) or LIN/UART interfaces, as confirmed in Section 2.3 of DS11620 Rev 8. CAN-FD interfaces are supported for runtime communication via the eight MCAN modules but are not connected to the BAF bootloader circuitry.

How many independent clock domains does the dual PLL system provide?

The SPC58EC80E7FMC0X implements two independent PLLs: PLL0 generates a stable clock domain for peripherals and system logic, while PLL1 provides an FM-modulated clock domain for the computational shell. Both PLLs accept inputs from the 40 MHz crystal oscillator or internal RC sources, and their outputs feed separate clock trees with configurable dividers per peripheral group.

Is the 10-bit SAR ADC with STDBY mode capable of conversion during STOP mode?

Yes - the 10-bit SAR ADC with STDBY mode is explicitly designed to operate during STOP and HALT low-power modes, drawing current in the µA range. Its dedicated reference and clock path allow autonomous sampling triggered by BCTU or PIT_RTI events without CPU intervention, as detailed in Section 4.12.3 of the DS11620 datasheet.
