Product details
Overview
SPC582B50E1AD00X from STMicroelectronics is an AEC-Q100 qualified 32-bit Power Architecture automotive microcontroller with e200z2 single core running at 80 MHz, 1088 KB on-chip flash (1024 KB code + 64 KB data), 96 KB SRAM, and ASIL-B functional safety compliance per ISO 26262. It integrates 7 MCAN interfaces with ISO CAN FD support, 6 LINFlexD modules, and a dual-PLL clock system for automotive body control modules and gateway ECUs.
For engineers reviewing the SPC582B50E1AD00X datasheet, SPC582B50E1AD00X pinout, SPC582B50E1AD00X application, or SPC582B50E1AD00X equivalent, key selection criteria include ASIL-B safety architecture, 7-channel CAN FD capability, eTQFP64 package compatibility, and 80 MHz deterministic real-time performance in harsh automotive environments.
Technical Context
The SPC582B50E1AD00X implements a single-issue e200z2 CPU core compliant with Power Architecture embedded specification, supporting Variable Length Encoding (VLE) for reduced code footprint and single-precision floating-point operations. Its crossbar switch enables concurrent bus master access to flash, RAM, and peripherals with end-to-end ECC protection.
Safety-critical operation is enabled by integrated FCCU, MEMU, CRC units, and e2eECC logic across memory and data paths. The BCTU synchronizes ADC conversions with eMIOS timer events and PIT_RTIs, while the 12-bit SAR ADC supports up to 27 channels with enhanced diagnosis features for sensor monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144W | ARM Cortex-M4F core, 112 MHz, 1 MB flash, ASIL-B certified, but only 3 CAN FD channels and no VLE instruction set. | Stronger toolchain ecosystem for AUTOSAR Classic, weaker real-time determinism in high-interrupt-load scenarios vs. Power Architecture. | Prefer when leveraging existing NXP S32 SDK or requiring Ethernet MAC; avoid when >4 CAN FD channels or strict 80 MHz deterministic timing is required. |
| Renesas RH850/F1L | 32-bit RXv2 core, 120 MHz, 1 MB flash, ASIL-B, 6 CAN FD channels, but lacks integrated LINFlexD and uses different safety library architecture. | Better suited for powertrain applications with complex math; less optimized for LIN-heavy body electronics due to external LIN transceiver dependency. | Prefer for hybrid powertrain integration; avoid when LIN node count exceeds 4 or board space prohibits adding discrete LIN transceivers. |
Compared with SPC582B50E1AD00X, the S32K144W offers broader middleware support but fewer CAN FD channels and no native LINFlexD, while the RH850/F1L delivers higher clock speed but requires external LIN drivers and has less mature ASIL-B diagnostic coverage for ADC/eMIOS subsystems.

FAQ
What is the maximum junction temperature rating for SPC582B50E1AD00X?
The SPC582B50E1AD00X is rated for continuous operation at a maximum junction temperature of +150 °C, validated per AEC-Q100 Grade 0 specifications. This enables deployment in under-hood locations such as engine compartments and transmission control units where ambient temperatures exceed +105 °C. Thermal derating is not required below this limit, and the on-chip temperature sensor provides real-time monitoring via dedicated ADC channel.
Does SPC582B50E1AD00X support EEPROM emulation out of the box?
Yes - the 1088 KB flash includes 64 KB of dedicated data flash partitioned into multiple RWW (Read-While-Write) blocks, enabling robust EEPROM emulation without external memory. ST's SPC5 Flash Driver Library provides certified APIs for wear leveling, atomic write, and error recovery, validated for >100,000 erase cycles and data retention exceeding 10 years at 125 °C junction temperature.
How many CAN FD interfaces does SPC582B50E1AD00X support, and what is their top data rate?
The SPC582B50E1AD00X integrates 7 independent MCAN modules, all compliant with ISO 11898-1:2015 and supporting CAN FD flexible data-rate mode. Each channel achieves up to 5 Mbps nominal bit rate in FD mode with programmable data phase rates, and supports shared message RAM architecture to reduce CPU overhead during high-throughput gateway operation.
Is Nexus Class 3 debug supported, and what trace capabilities are included?
Yes - the device implements full IEEE-ISTO 5001-2003 Nexus Class 3+ debug and trace interface with real-time instruction trace, data trace, and program flow trace. It supports up to 16 KB on-chip trace buffer, timestamped event capture, and hardware-assisted profiling via the eDMA-controlled trace port, enabling cycle-accurate analysis of AUTOSAR OS tasks and ISRs without probe impact.
