STMicroelectronics SPC58NN84C3RMHBR

Overview

SPC58NN84C3RMHBR from STMicroelectronics is a 32-bit Power Architecture automotive microcontroller with five e200z4256n3 CPU cores (two in lockstep), 6576 KB on-chip flash (6288 KB code + 288 KB data), 128 KB general-purpose SRAM, ASIL-D safety certification per ISO 26262, and integrated Hardware Security Module (HSM). It targets engine control units (ECUs) requiring functional safety, real-time deterministic timing, and multi-protocol connectivity.

For engineers reviewing the SPC58NN84C3RMHBR datasheet, SPC58NN84C3RMHBR pinout, SPC58NN84C3RMHBR application, or SPC58NN84C3RMHBR equivalent, key selection criteria include dual-channel FlexRay support, 7 LINFlexD interfaces, 8 MCAN modules with CAN-FD and TTCAN, GTM344 timer module for motor control, and junction temperature range of –40 °C to 165 °C.

Technical Context

The device implements a dual-phase-locked loop (PLL) architecture: PLL0 provides stable clock domains for peripherals, while PLL1 supports FM modulation for computational shells. Its memory subsystem features end-to-end ECC across Flash, SRAM, and caches, with dedicated MEMU for error collection and FCCU for failure notification handling.

Peripherals are accessed via dual crossbar switches enabling concurrent bus master access with guaranteed latency. The GTM344 module contains five programmable fine-grain multi-threaded cores, 61 KB RAM, and hardware acceleration for engine timing, PWM generation, and safety-critical signal conditioning - all validated under ASIL-D flow.

FAQ

What is the maximum junction temperature rating for SPC58NN84C3RMHBR?

The device is rated for continuous operation at junction temperatures from –40 °C to 165 °C, validated per AEC-Q100 Grade 0. Thermal derating begins above 150 °C in production test; full electrical specifications are guaranteed up to 165 °C in design validation.

Does SPC58NN84C3RMHBR support secure boot with cryptographic verification?

Yes. The integrated Hardware Security Module (HSM) performs AES-128 decryption and SHA-256 hash verification of boot images stored in Boot Assist Flash (BAF), enforcing immutable root-of-trust before any application code executes.

How many CAN-FD interfaces does SPC58NN84C3RMHBR provide, and what is their arbitration capability?

It integrates seven MCAN modules and one M-TTCAN module, all compliant with ISO 11898-1:2015 CAN-FD. Each supports flexible data rate up to 5 Mbps, with hardware message filtering, TX/RX FIFOs, and time-triggered transmission scheduling in the M-TTCAN instance.

Is the GTM344 module capable of closed-loop motor control without CPU intervention?

Yes. GTM344's five programmable multi-threaded cores execute autonomous timing sequences - including PWM generation, capture of encoder/resolver edges, and dead-time insertion - using only its 61 KB RAM and internal event routing, freeing CPU cores for higher-layer algorithms.
