Product details
Overview
SPC564B70L7B9ECX from STMicroelectronics is a 32-bit automotive MCU based on the Power Architecture® e200z4d core, operating up to 120 MHz (200 MIPs), with 2 MByte on-chip Flash (ECC), 256 KByte SRAM (ECC), and integrated FlexCAN, DSPI, LINFlex, Ethernet, and Cryptographic Services Engine (AES-128). It targets body control modules requiring functional safety compliance and real-time diagnostics in vehicles.
For engineers reviewing the SPC564B70L7B9ECX datasheet, SPC564B70L7B9ECX pinout, SPC564B70L7B9ECX application, or SPC564B70L7B9ECX equivalent, key selection criteria include dual-core timing capability (e200z4d + e200z0h), 6 FlexCAN interfaces with 64 buffers each, Fast Ethernet Controller (MII), and dedicated lighting diagnostic features including PWM-synchronized ADC conversion and advanced shifted PWM generation.
Technical Context
This MCU integrates two independent Power Architecture® cores: a high-performance e200z4d (120 MHz) for main application tasks and a safety-monitoring e200z0h (80 MHz) supporting lockstep or split-mode operation. Its memory subsystem includes ECC-protected 2 MByte Flash, 256 KByte SRAM, and 64 KByte Data Flash, all backed by a 16-entry MPU and user-selectable Memory BIST.
The peripheral set is optimized for automotive body electronics: 64-channel eMIOS for flexible PWM/IC/OC timing, dual ADCs (10-bit + 12-bit, up to 90 total channels), 6 FlexCAN controllers, 10 LINFlex/UARTs, 8 DSPI channels, I²C, FlexRay (dual-channel, 128 buffers), and a full MII Fast Ethernet Controller - all coordinated via a 32-channel eDMA with multiple request sources.

FAQ
What is the maximum operating frequency and core configuration of the SPC564B70L7B9ECX?
The SPC564B70L7B9ECX integrates two Power Architecture® cores: the e200z4d runs at up to 120 MHz (200 MIPs) for primary application tasks, and the e200z0h operates at up to 80 MHz (75 MIPs) for safety monitoring or co-processing. Both cores are physically implemented on-die and share memory-mapped peripherals via a unified bus matrix.
Does the SPC564B70L7B9ECX support functional safety standards such as ISO 26262?
Yes - the device includes hardware safety features required for ASIL-B compliance, including ECC on Flash/SRAM, Memory BIST, Clock Monitoring Unit (CMU), Safety System Watchdog Timer (SWT), and dual-core lockstep capability. ST provides ISO 26262-ready safety manuals, FMEDA reports, and diagnostic software libraries to support certification efforts.
What Ethernet interface does the SPC564B70L7B9ECX provide, and what PHY compatibility is required?
The MCU integrates a full MII (Media Independent Interface) Fast Ethernet Controller supporting 10/100 Mbps operation. It requires an external PHY compliant with IEEE 802.3u; no internal PHY is included. Signal timing meets MII specifications per Section 3.18 of the datasheet, and layout must follow controlled-impedance routing guidelines for RX/TX differential pairs.
Can the SPC564B70L7B9ECX operate from a single 5 V supply, and how is voltage regulation handled?
Yes - it supports single 5 V or 3.3 V supply operation. An on-chip linear voltage regulator generates internal core and I/O voltages; an external ballast NPN transistor (connected to VRB pin) is required for current handling and thermal stability. The regulator's output is monitored by the Voltage Monitor Unit to trigger reset on undervoltage conditions.
