STMicroelectronics SPC58NE84E7QMHAR

Overview

SPC58NE84E7QMHAR 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 powertrain and chassis control. It integrates dual FlexRay, 8 MCAN interfaces with CAN-FD and TTCAN support, dual 10/100 Mbps Ethernet with IEEE 1588 timestamping, and GTM343 timer module with 144 channels.

For engineers reviewing the SPC58NE84E7QMHAR datasheet, SPC58NE84E7QMHAR pinout, SPC58NE84E7QMHAR application, or SPC58NE84E7QMHAR equivalent, key selection criteria include ASIL-D fault containment, multi-core lock-step integrity, flash partitioning for EEPROM emulation, GTM343 channel count for engine timing, and HSM-enabled secure boot via CAN/LIN UART.

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 dual crossbar switch enables concurrent access to Flash, SRAM, and peripherals by multiple bus masters with end-to-end ECC protection across all data paths.

Memory subsystem includes 6576 KB on-chip flash with read-while-program/erase capability across two code partitions, 608 KB general-purpose SRAM plus 160 KB core-local RAM, and dedicated 61 KB GTM RAM. Safety logic comprises FCCU, MEMU, CRC unit, and lock-step eDMA controllers (64+32 channels) with error detection and reporting.

Key Specifications

Pinout & Package

SPC58NE84E7QMHAR is packaged in FPBGA292 (17 × 17 × 1.8 mm) with 292 I/O pads. The package supports internal linear regulator with external ballast and includes dedicated power, ground, clock, reset, JTAG/Nexus debug, and functional I/O groups aligned to peripheral clusters (GTM, CAN, Ethernet, ADC, etc.). Pin assignments follow ST's IO_Definition document for SPC58xEx series.

FAQ

What is the maximum junction temperature rating for SPC58NE84E7QMHAR?

The device is rated for −40 °C to 165 °C junction temperature, validated per AEC-Q100 Grade 0 requirements. This enables operation in extreme under-hood environments such as near turbochargers or exhaust manifolds, where ambient temperatures exceed 125 °C and thermal transients demand robust silicon reliability.

Does SPC58NE84E7QMHAR support secure boot with cryptographic verification?

Yes-the integrated Hardware Security Module (HSM) performs asymmetric signature verification (RSA-2048 or ECDSA) on firmware images stored in Boot Assist Flash (BAF) before execution. It supports secure serial bootloading via CAN or LIN/UART with authenticated key exchange and encrypted payload transfer.

How does the GTM343 timer module differ from standard PWM peripherals in automotive MCUs?

GTM343 contains five independent programmable multi-threaded cores and 61 KB of dedicated RAM, enabling complex timing sequences-such as variable cam phasing, cylinder deactivation, or torque vectoring-that require concurrent execution of multiple timing tasks with nanosecond-level precision and hardware-based fault containment.

Can SPC58NE84E7QMHAR operate with external regulators only, or does it require internal regulation?

It supports flexible power architecture: external 1.2 V core and 3.3–5 V I/O supplies are mandatory for FPBGA292 packages. Unlike eLQFP176 variants, this part does not integrate an SMPS or linear regulator-it relies entirely on externally supplied, tightly regulated voltages meeting ST's ripple and sequencing specifications.
