Product details
Overview
SPC564B74L7C8E0X from STMicroelectronics is a 32-bit automotive MCU based on the Power Architecture® e200z4d core, operating up to 120 MHz and delivering 200 MIPs. It integrates 3 MByte on-chip Flash with ECC, 256 KByte SRAM with ECC, dual ADC (10-bit/12-bit), 6 FlexCAN interfaces, Fast Ethernet Controller, and Cryptographic Services Engine (AES-128). It targets body control modules requiring functional safety, secure boot, and real-time I/O handling in vehicles.
For engineers reviewing the SPC564B74L7C8E0X datasheet, SPC564B74L7C8E0X pinout, SPC564B74L7C8E0X application, or SPC564B74L7C8E0X equivalent, key selection criteria include ASIL-B compliance support, CAN/FlexRay/Ethernet coexistence, PWM-synchronized ADC for lighting control, and dual-core debug capability via Nexus 3+ on LBGA256 packages.
Technical Context
This MCU implements a dual-core architecture: primary e200z4d core (120 MHz) for main application execution and secondary e200z0h core (80 MHz) for safety monitoring or peripheral management. Memory subsystem includes triple ECC-protected memory domains (code flash, data flash, SRAM), MPU with 16 entries, and user-selectable BIST for runtime integrity verification.
Timing and safety infrastructure comprises Safety System Watchdog Timer (SWT), Clock Monitoring Unit (CMU), Real-Time Clock (RTC/API), and dedicated diagnostic features including CAN Sampler in STANDBY mode and advanced shifted PWM generation synchronized with ADC conversion-enabling precise closed-loop lighting control without CPU intervention.

Use Value: Dual-core isolation with separate memory protection units (MPU) enables ASIL-B decomposition without hardware lockstep, lowering BOM cost vs. dual-die solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC564B74L7C8E0Y | Same die, different temperature grade (–40 to 150 °C vs. –40 to 125 °C); identical pinout and firmware compatibility | Targeted for under-hood applications exceeding 125 °C ambient (e.g., near turbocharger, exhaust manifold) | Select when extended junction temperature rating is required; otherwise, E0X offers optimal cost/performance for cabin and chassis locations |
| SPC56EC74B3 | Same LBGA256 package and feature set, but belongs to SPC56ECxx series - includes enhanced safety libraries and pre-certified ASIL-B drivers | Used where OEM mandates certified safety software stacks (e.g., ISO 26262 ASIL-B production code) | Choose when safety certification artifacts (FMEDA, TÜV reports) are contractually required; E0X suits development and non-certified production builds |
Compared with SPC564B74L7C8E0X, the E0Y variant extends thermal range without functional change, while the SPC56EC74B3 adds certified safety software overhead - making E0X ideal for cost-sensitive, non-certified automotive body electronics with full hardware capability.

FAQ
What is the maximum operating frequency and corresponding performance of the SPC564B74L7C8E0X?
The SPC564B74L7C8E0X features an e200z4d core rated for up to 120 MHz, delivering 200 MIPs of processing performance. This frequency is achievable under recommended operating conditions (3.3 V supply, ambient temperature ≤125 °C) with proper decoupling and thermal management per Section 3.5 of the datasheet. The secondary e200z0h core operates up to 80 MHz (75 MIPs) and is typically used for safety monitoring or background tasks.
Does the SPC564B74L7C8E0X support ISO 26262 functional safety certification?
The SPC564B74L7C8E0X provides hardware features required for ASIL-B compliance-including ECC memory, MPU, SWT, CMU, and dual-core independence-but does not ship with pre-certified safety libraries. ST offers the SPC56ECxx series (e.g., SPC56EC74B3) with ISO 26262 ASIL-B certified software drivers and documentation. Customers must perform their own safety analysis and qualification for SPC564Bxx usage.
What debug interfaces are available on the LBGA256 package of this MCU?
The SPC564B74L7C8E0X in LBGA256 package supports Nexus 3+ debug interface, providing real-time instruction trace, data watchpoints, and streaming trace via dedicated pins (TRACESWO, TRACECLK, etc.). All packages also include Nexus 1-level JTAG for basic programming and breakpoint debugging. Nexus 3+ capability is exclusive to LBGA256 and not available on LQFP variants.
Can the SPC564B74L7C8E0X operate from a single 5 V supply?
Yes, the SPC564B74L7C8E0X supports single-supply operation at either 3.3 V or 5.0 V, as specified in Tables 10 and 11 of the datasheet. When using 5 V, the internal voltage regulator generates regulated 3.3 V for core logic, while VDD_IO remains at 5 V to drive higher-voltage peripherals. External ballast transistor and decoupling capacitors must be implemented per Figure 8 and Section 3.8.1.
