Product details
Overview
SPC564B64L7C800X 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 1.5 MByte on-chip Flash with ECC, 256 KByte SRAM with ECC, dual ADCs (10-bit and 12-bit), six FlexCAN interfaces, and Fast Ethernet Controller - deployed in body control modules for vehicle lighting, door/window actuation, and gateway functions.
For engineers reviewing the SPC564B64L7C800X datasheet, SPC564B64L7C800X pinout, SPC564B64L7C800X application, or SPC564B64L7C800X equivalent, key selection criteria include ASIL-B-ready safety features (SWT, MPU, memory BIST), CAN/LIN/FlexRay/Ethernet coexistence, diagnostic PWM/ADC synchronization for lighting control, and -40°C to +125°C operation in LQFP176 package.
Technical Context
This MCU implements dual-core architecture: primary e200z4d core (120 MHz) for real-time body control tasks and auxiliary e200z0h core (80 MHz) for background diagnostics or communication stack handling. Memory subsystem includes triple-ECC-protected Flash (1.5 MB), SRAM (256 KB), and Data Flash (64 KB), all managed by a 16-entry MPU and user-selectable Memory BIST.
Timing and safety infrastructure comprises Safety System Watchdog Timer (SWT), Real-Time Clock (RTC/API), Clock Monitoring Unit (CMU), and Nexus 3+ debug interface (on LBGA256 variants). The device supports ultra-low-power STANDBY mode with CAN ID sampling and fast wake-up from RAM execution - critical for always-on automotive body networks.

Key Features
| Feature | Design Value |
|---|---|
| Advanced Lighting Diagnostics | Hardware-synchronized PWM generation and ADC conversion - eliminates software timing jitter for LED current sensing and dimming accuracy |
| Cryptographic Services Engine (CSE) | AES-128 encryption/decryption and CMAC authentication - enables secure boot, firmware signing, and key provisioning without external security IC |
| eDMA Controller | 32-channel enhanced DMA with scatter-gather support - offloads CPU from high-bandwidth transfers (e.g., Ethernet frame buffering, ADC data streaming) |
| Low-Power STANDBY Mode | Retains CAN ID in dedicated sampler register while powering down core and most peripherals - enables <10 µA sleep current with instant wake-on-CAN |
| Flexible Clock Architecture | Four independent clock sources (4–40 MHz XTAL, 32 kHz AUX, 16 MHz IRC, 128 kHz IRC) with FMPLL and Clock Monitoring Unit - ensures fail-safe clock redundancy and drift detection |
Applications
| LED Headlamp Control Module | Body Control Module (BCM) |
|---|---|
Use Scenario: Dynamic adaptive front-lighting system (AFS) with matrix LED arrays, thermal monitoring, and CAN-based beam shaping commands. IC Role / Device Role / Timing Role: Main controller executing PWM dimming algorithms, synchronizing ADC readings with LED switching edges, and managing CAN/FlexRay communication with ADAS ECU. Use Value: Hardware-level PWM/ADC sync ensures ±0.5% current regulation accuracy across temperature, enabling compliance with ECE R149 photometric standards. |
Use Scenario: Centralized vehicle body management integrating door lock/unlock, window lift, mirror fold, and interior lighting via LIN and CAN. IC Role / Device Role / Timing Role: Domain controller running AUTOSAR-compliant BSW, coordinating LIN slave nodes and aggregating CAN messages for gateway forwarding. Use Value: Six independent FlexCAN controllers with 64-message buffers each eliminate message loss during peak bus load (e.g., simultaneous door actuation + lighting fade). |
| Automotive Gateway | Electric Power Steering (EPS) Support ECU |
Use Scenario: In-vehicle network bridge between high-speed CAN FD, LIN, FlexRay, and Ethernet domains in zonal architectures. IC Role / Device Role / Timing Role: Protocol translator and firewall enforcing message filtering, routing, and rate adaptation between heterogeneous buses. Use Value: Integrated Fast Ethernet Controller (MII) and dual FlexRay channels enable deterministic 100BASE-T1 backbone connectivity while maintaining legacy bus interoperability. |
Use Scenario: Secondary ECU supporting torque assist calculation, motor phase current sensing, and CAN communication with main EPS MCU. IC Role / Device Role / Timing Role: Safety-monitoring companion processor performing cross-checks on motor position, current, and temperature using redundant ADC paths. Use Value: Dual 12-bit ADCs with analog watchdog detect sensor faults within 10 µs, satisfying ASIL-B diagnostic coverage requirements for EPS functional safety. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K144 | ARM Cortex-M4F core (112 MHz), 512 KB Flash, no integrated Ethernet or FlexRay | Targeted at entry-level body control; lacks Fast Ethernet and dual FlexRay required for zonal gateways | Select when cost-sensitive LIN/CAN-only designs dominate and ARM ecosystem tooling is preferred |
| Renesas RH850/F1L | 32-bit RH850 core (120 MHz), 2 MB Flash, CAN FD only (no FlexRay/Ethernet), different safety IP (RSCAN vs SWT) | Focused on powertrain-adjacent body systems; no native Ethernet PHY interface | Choose for legacy Renesas toolchain continuity and where CAN FD suffices without multi-protocol convergence |
Compared with SPC564B64L7C800X, the NXP S32K144 offers lower cost and broader ARM tooling but omits Ethernet/FlexRay needed for next-gen gateways; the RH850/F1L provides comparable compute but lacks the integrated Ethernet MAC and dual FlexRay channels essential for high-integration domain controllers.

FAQ
What is the maximum operating frequency and core type of the SPC564B64L7C800X?
The SPC564B64L7C800X features two Power Architecture® cores: the primary e200z4d core runs at up to 120 MHz (200 MIPs), and the secondary e200z0h core operates at up to 80 MHz (75 MIPs). Both cores are fully compliant with the Power ISA v2.03 specification and support hardware floating-point operations via optional FPU extensions.
Does the SPC564B64L7C800X support AEC-Q100 qualification and what grade is it rated for?
Yes, the SPC564B64L7C800X is qualified per AEC-Q100 Rev G, Grade 1, meaning it operates reliably from -40°C to +125°C ambient temperature. This qualification covers stress testing for HTOL, TCT, ESD, and latch-up, and is documented in ST's official product change notifications and qualification reports.
How many CAN interfaces does the SPC564B64L7C800X integrate, and what buffer capacity does each provide?
The SPC564B64L7C800X integrates six FlexCAN modules, each with 64 message buffers. Each buffer supports full mailbox configuration (ID masking, direction control, priority assignment), and all six CAN controllers operate independently with configurable bit rates up to 1 Mbps and built-in loopback/self-test modes.
Is the SPC564B64L7C800X pin-compatible with other devices in the SPC564Bxx or SPC56ECxx families?
No - the SPC564B64L7C800X uses the LQFP176 package, while SPC56ECxx variants in LBGA256 (e.g., SPC56EC64B3) have different pin counts, signal assignments, and power/ground layouts. Pin compatibility exists only within same-package variants (e.g., SPC564B64L7 vs SPC564B70L7 in LQFP176), not across package types or sub-families.
