It supports AEC-Q100 Grade 1 qualification and ISO 26262 ASIL-A compliance for gasoline/diesel powertrain control.
For engineers reviewing the SPC572L64F2BC6AR datasheet, SPC572L64F2BC6AR pinout, SPC572L64F2BC6AR application, or SPC572L64F2BC6AR equivalent, key selection criteria include its dual M_CAN interfaces, SENT channel count, FEC Ethernet support, and eTQFP100 package compatibility for high-pin-count automotive ECU designs.
Technical Context
This MCU implements a single-issue e200z2 core with VLE instruction set and hardware single-precision floating-point unit. Its system architecture integrates SIUL2 for I/O configuration, SMPU for memory protection, and eDMA with 16 channels supporting up to 60 sources - enabling deterministic real-time response in engine control loops.
The peripheral suite includes three 12-bit SAR ADCs and one 16-bit Sigma-Delta ADC with decimation unit, four SENT receivers, two LINFlexD modules, two DSPI controllers, and a Fast Ethernet Controller (FEC) compliant with IEEE 802.3. Clocking relies on a single PLL generating stable domains for both core and peripherals.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive powertrain microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPC572L64E3 | Same die, eTQFP80 package (80-pin, 10×10 mm), 1568 KB flash, but no FEC Ethernet controller. | Suitable for cost-sensitive powertrain modules where Ethernet connectivity is not required (e.g., standalone TCM). | Select when board space constraints favor smaller footprint and Ethernet is unused. |
| SPC574K72E3 | Higher-performance e200z4 dual-core, 2 MB flash, 256 KB SRAM, added HSM security module, but no SENT or GTM101. | Targeted at ASIL-B applications requiring cryptographic acceleration and secure boot, not legacy SENT-based sensor ecosystems. | Choose for next-gen hybrid powertrains needing secure OTA updates and higher compute throughput. |
Compared with SPC572L64F2BC6AR, SPC572L64E3 trades Ethernet and package size for lower cost and footprint, while SPC574K72E3 upgrades compute and security at the expense of SENT/GTM101 support - making the original optimal for Ethernet-enabled, SENT-rich ASIL-A powertrain ECUs.

FAQ
What automotive safety standards does SPC572L64F2BC6AR support?
SPC572L64F2BC6AR is AEC-Q100 qualified (Grade 1, −40 °C to +125 °C) and architected to meet ISO 26262 ASIL-A requirements. It includes hardware features such as SMPU, built-in self-test (BIST), lockstep-capable peripherals, and Nexus debug trace - all documented in ST's functional safety manual UM1929.
Does this MCU support Ethernet communication out of the box?
Yes, SPC572L64F2BC6AR integrates a Fast Ethernet Controller (FEC) compliant with IEEE 802.3 RMII interface, supporting 10/100 Mbps operation. It requires external PHY and proper PCB layout for impedance-controlled traces, but no external MAC or protocol stack hardware is needed.
How many SENT channels are implemented, and what version do they support?
The MCU integrates four dedicated SENT receiver channels compliant with SENT v3.0 specification (SAE J2716). Each channel supports variable-length messages, CRC validation, and configurable baud rates up to 125 kbps - enabling direct connection to manifold absolute pressure (MAP), throttle position (TPS), and exhaust gas recirculation (EGR) sensors.
What is the role of the GTM101 module in powertrain applications?
GTM101 provides 72 programmable timer channels (16 input, 56 output) for ultra-precise PWM generation, input capture, and time-triggered communication. In powertrain use, it delivers <1 µs jitter on injector driver signals, synchronizes ADC sampling with crankshaft position, and implements SENT transmitter logic - all in hardware without CPU intervention.
