STMicroelectronics SPC58EE84E7QMSAR

Overview

SPC58EE84E7QMSAR from STMicroelectronics is a 32-bit Power Architecture automotive microcontroller with triple e200z4 CPU cores (two in lock-step with checker cores), 6576 KB on-chip flash (6288 KB code + 288 KB data), 608 KB general-purpose SRAM, and ASIL-D compliance per ISO 26262 for safety-critical engine control units. It integrates dual FlexRay, 8 MCAN (including one TTCAN), two 10/100 Mbps Ethernet controllers with IEEE 1588 timestamping, GTM343 timer module with 144 channels, and HSM for secure boot.

For engineers reviewing the SPC58EE84E7QMSAR datasheet, SPC58EE84E7QMSAR pinout, SPC58EE84E7QMSAR application, or SPC58EE84E7QMSAR equivalent, key selection criteria include ASIL-D fault containment, dual-core lock-step execution integrity, Flash EEPROM emulation capability, GTM-based motor timing precision, and CAN-FD/TTCAN coexistence in powertrain domain controllers.

Technical Context

The device implements a dual-phase-locked loop architecture: PLL0 supplies stable clocks to peripherals and memory subsystems, while PLL1 provides frequency-modulated domains for computational shells. Its GTM343 module features five programmable multi-threaded cores and 61 KB dedicated RAM, enabling deterministic real-time signal processing for engine valve timing and torque control.

The memory subsystem includes end-to-end ECC protection across instruction cache, data cache, SRAM, and Flash-verified via MEMU error reporting-and supports concurrent read-while-read between two code Flash partitions. The HSM enforces secure boot through cryptographic signature verification of BAF and main Flash contents before execution.

Key Specifications

Pinout & Package

SPC58EE84E7QMSAR is packaged in FPBGA292 (17 × 17 × 1.8 mm) with 292 I/O balls. Pin assignments follow ST's IO_Definition document for SPC58xEx series; ball mapping includes dedicated power domains (VDD_CORE, VDD_IO, VDDA), system control (PORST, ESR0), clock inputs (XOSC_40M, XOSC_32K), and functional groups for CAN, FlexRay, Ethernet, GTM, and ADC interfaces.

FAQ

What is the maximum junction temperature rating for SPC58EE84E7QMSAR?

The device is rated for junction temperatures from –40 °C to 165 °C, validated per AEC-Q100 Grade 0. Thermal derating begins at 150 °C in production test; full characterization up to 165 °C occurs during design validation using thermal simulation and package-level testing.

Does SPC58EE84E7QMSAR support boot from external serial flash?

No-boot is restricted to internal Flash only. The Boot Assist Flash (BAF) region supports factory programming via asynchronous CAN or LIN/UART serial bootload, but runtime boot source selection is fixed to internal Flash partitions with no external SPI NOR/NAND interface.

How many CAN-FD interfaces support ISO 11898-1:2015 with bit rate switching?

All eight MCAN interfaces comply with ISO 11898-1:2015 and support CAN-FD bit rate switching. One instance additionally supports TTCAN per ISO 11898-4, providing time-triggered scheduling with guaranteed latency ≤ 2 µs for safety-critical messages.

Is the GTM343 module accessible to all CPU cores simultaneously?

Yes-the GTM343 is connected via the high-speed crossbar switch and supports concurrent access from all three CPU cores. Each core can independently configure GTM submodules (e.g., TOM, ATOM, SER) using dedicated address spaces and interrupt vectors mapped to INTC channels.
