SPC574S64E3CEFAR 概述
An automotive-grade Power Architecture MCU is a microcontroller based on the Power instruction set originally developed for automotive powertrain, chassis, and safety domains where deterministic interrupt latency, lock-step cores, and ASIL-rated peripherals are mandatory. It belongs to the broader family of automotive MCUs > chassis/safety microcontrollers > embedded control processors > 32-bit microcontrollers > semiconductors, sitting at the intersection of compute density and functional safety. The SPC574Sx family uses dual e200z4 cores, often configured in delayed lock-step or dual parallel mode, to provide fault detection coverage suitable for ASIL-D systems.
Key features include 1.5MB Flash (1.5M x 8) for application and bootloader code, an integrated 1.2V core voltage regulator with bypass mode for an external supply, multiple CAN and LIN interfaces for in-vehicle networking, and a FlexPWM module with a fault-collection unit tailored for motor and solenoid control. The on-chip regulator simplifies PCB layout by removing an external point-of-load converter for the core logic supply.
The device integrates a tightly-coupled deterministic interrupt controller, hardware security modules (CSE - cryptographic services engine) for secure boot and message authentication, and an eDMA engine for low-overhead data movement, freeing the cores for control loops. Lock-step and ECC on SRAM/Flash support ASIL-D target applications in steering, braking, and airbag systems.
Typical applications include electric power steering (EPS), electronic stability control (ESC/ESP), anti-lock braking systems (ABS), active suspension control, and airbag restraint controllers - all ASIL-D domains that benefit from the dual-core lock-step architecture and the chassis-focused peripheral set. Industrial safety applications such as functional-safe motor drives and SIL-rated process controllers can also leverage this MCU.
When designing with this device, carefully plan the lock-step core configuration and route decoupling on the internal 1.2V rail according to ST's AN4379 guidelines to maintain fault detection coverage. Choose between on-chip regulator and bypass mode based on whether the system can tolerate the regulator's power dissipation versus the cost of an external 1.2V supply. This page synthesizes distributor pricing, drop-in alternatives within the SPC574Sx family, and practical design notes beyond the manufacturer datasheet.

典型应用
SPC574S64E3CEFAR 适用于 6 应用s: Electric Power Steering (EPS), Electronic Stability Control (ESC/ESP), Anti-lock Braking System (ABS) ECU, Airbag Restraint Controller, Active Suspension Control Module, Industrial Functional-Safety Motor Drive.
Electric Power Steering (EPS)
The SPC574S64E3CEFAR's dual e200z4 cores at 140MHz run in delayed lock-step to deliver the ASIL-D fault detection required for steer-by-wire and column-assist EPS systems. Its FlexPWM module with the fault-collection unit directly drives the torque-vectoring motor while 1.5MB Flash absorbs the calibration tables for torque-feel and on-center handling. The eTQFP exposed pad removes heat from the chassis-mounted ECU without an external heatsink.
推荐
Electronic Stability Control (ESC/ESP)
The SPC574S64E3CEFAR's deterministic interrupt response and 1.5MB Flash handle the high-rate wheel-speed loop, hydraulic-modulator sequencing, and yaw-rate fusion that ESC demands. Dual-core lock-step satisfies the ASIL-D self-check on the brake-by-wire path while the integrated CSE signs CAN-FD messages for spoof protection. Its -40C to +125C operating range tolerates the underhood and brake-ECU thermal envelope without derating.
推荐
Anti-lock Braking System (ABS) ECU
The SPC574S64E3CEFAR integrates the lock-step dual e200z4 cores at 140MHz that ABS ECUs need to read four-wheel-speed sensors, run the slip-control algorithm at sub-millisecond cadence, and command brake-line valves with deterministic PWM. Its 1.5MB Flash holds the slip-threshold calibration across vehicle variants while the on-chip 1.2V regulator reduces external BOM in the price-sensitive ABS market segment.
推荐
Airbag Restraint Controller
The SPC574S64E3CEFAR's dual-core lock-step architecture and ECC-protected SRAM/Flash deliver the ASIL-D self-test coverage that airbag controllers require under ISO 26262. The FlexPWM with fault-collection unit triggers squib deployment with single-channel or dual-channel arming logic, while the integrated CSE authenticates sensor messages over CAN-FD to prevent replay attacks. The 1.5MB Flash absorbs the large lookup tables for occupant-classification and crash-severity decision trees.
推荐
Active Suspension Control Module
The SPC574S64E3CEFAR coordinates four damper actuators and ride-height sensors at 140MHz per core, with deterministic PWM timing to keep chassis-control latency below a 1ms sense-compute-actuate window. The 1.5MB Flash stores ride-comfort and handling-mode calibration, while the integrated CSE signs ECU-to-ECU messages on the CAN-FD chassis backbone. The exposed-pad eTQFP dissipates the regulator's heat in a sealed damper module without added cooling.
推荐
Industrial Functional-Safety Motor Drive
Beyond automotive, the SPC574S64E3CEFAR's lock-step e200z4 cores suit IEC 61508 SIL-3 industrial drives for servos, robotics, and process valves. The FlexPWM with fault-collection unit drives IGBT bridges directly, while the CAN-FD interface simplifies integration into SIL-rated fieldbus networks. The 100-pin eTQFP exposed pad mounts cleanly on standard industrial control PCBs without rework.

设计说明
The internal 1.2V core regulator simplifies BOM but adds self-heating of about 0.5W to 1W depending on clock speed and core activity. Provide at least 1 square inch of unbroken copper pour on the exposed pad to keep the junction temperature rise below 30C, and follow ST's AN4379 decoupling guidelines (place 100nF + 4.7uF X7R right at VDD/VSS pins). For standby-sensitive designs, enable bypass mode and supply 1.2V directly from an external PMIC to drop internal dissipation to near zero.
Route the lock-step compare error line and the fault-collection inputs away from noisy PWM traces to avoid spurious faults. Place CAN-FD transceiver crystals and bypass capacitors within 5mm of the OSC pins; longer traces couple radiated emissions into the PLL and degrade CAN-FD bit timing. The exposed pad must be soldered for both thermal and electrical (ground) connection - missing solder joints degrade heat dissipation and cause EMC compliance failures.
The SPC574S64E3CEFAR is marked NRND (Not Recommended for New Designs) by ST per the product page. For new designs targeting chassis or safety, evaluate SPC58EC, SPC58NG, or AURIX TC3xx families for a longer product lifecycle. If you must design in this part, lock in long-term supply and confirm date code policy with your distributor before committing to PCB layout.
