Product details

The SPC572L64E3BC6AR is a 32-bit single-core microcontroller from STMicroelectronics' SPC572Lx series, built around the e200z2 core and running at 80 MHz. It carries 1.5 MB of Flash program memory, 64 KB of RAM, and a dedicated 32 KB EEPROM block — enough for a full engine-control or transmission-ECU firmware image plus calibration tables that survive power cycles.

The e200z2 core runs at 80 MHz. Paired with 1.5 MB Flash and 64 KB RAM, the part can host a full AUTOSAR stack or a single-threaded control loop without external memory. The separate 32 KB EEPROM (32K x 8) allows wear-leveled storage of DTCs, odometer, and trim values.

No immediate LTB risk, but as with any automotive MCU, keep an eye on ST's PCN notifications for package or wafer-fab changes.

Integration note: package and power

Supply is 3.3 V or 5 V; the dual-range Vcc/Vdd lets the MCU interface directly with 5 V sensor outputs and 3.3 V SPI peripherals. The on-chip POR, LVD, and WDT peripherals handle brown-out and watchdog supervision without external reset ICs — one less component to qualify.

Frequently asked questions

Is SPC572L64E3BC6AR AEC-Q100 qualified?

Yes. The SPC572L64E3BC6AR is part of the Automotive, AEC-Q100 series from STMicroelectronics, qualified for automotive applications. The listed operating temperature range of -40°C to 125°C supports under-hood and engine-bay deployment. PPAP documentation should be available from ST for OEM audit.

Where can I buy SPC572L64E3BC6AR and how do I get a price?

This part is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing — no stock or price figures are published here, but the line is active and quotable.

What are the specifications of SPC572L64E3BC6AR?

Key specs: e200z2 32-bit core at 80 MHz, 1.5 MB Flash, 64 KB RAM, 32 KB EEPROM, CANbus/Ethernet/LINbus/SPI/UART interfaces, -40°C to 125°C, 3.3 V / 5 V supply, 100-eTQFP with exposed pad.

When sourcing SPC572L64E3BC6AR, what's the closest functional second-source — STM32L151CBU6A?

The STM32L151CBU6A is a functional peer from ST's STM32L1 series, but it is not a pin-compatible second source. The STM32L151 runs an ARM Cortex-M3 at 32 MHz (vs 80 MHz e200z2), has 128 KB Flash and 32 KB RAM (vs 1.5 MB / 64 KB), and is commercial/industrial grade (85°C max vs 125°C). The SPC572L64E3BC6AR is AEC-Q100 qualified; the STM32L151 is not. For a true second source, look at other SPC572Lx density variants within the same package family.
