Overview
SPC572L64E3BC6AR from STMicroelectronics is an AEC-Q100 qualified 32-bit Power Architecture® VLE-compliant MCU designed for automotive powertrain control, featuring a single e200z2 CPU core, 1568 KB on-chip RWW flash with EEPROM emulation (32 KB), 64 KB SRAM, and integrated GTM101 intelligent timer module with 72 channels.
For engineers reviewing the SPC572L64E3BC6AR datasheet, SPC572L64E3BC6AR pinout, SPC572L64E3BC6AR application, or SPC572L64E3BC6AR equivalent, key selection criteria include ASIL-A compliance, dual M_CAN interfaces, SENT channel support for sensor interfacing, and eTQFP100 packaging for high-pin-count automotive ECU designs.
Technical Context
This MCU implements a single-issue e200z2 core compliant with Power Architecture® VLE instruction set, supporting single-precision floating-point operations and boot assist via UART/LIN/CAN. Its system architecture integrates SIUL2 for I/O configuration, SMPU for memory protection, and eDMA with 16 channels servicing up to 60 sources.
The timing subsystem includes four 32-bit and one 64-bit PIT channels, a single PLL generating stable clock domains for core and peripherals, and GTM101 - an autonomous complex timer with 16 inputs and 56 outputs for engine timing, PWM generation, and capture/compare functions in real-time powertrain control loops.

FAQ
What is the maximum operating junction temperature for SPC572L64E3BC6AR?
The device is rated for continuous operation up to 125 °C junction temperature, validated per AEC-Q100 Grade 1 specifications. Thermal characteristics for eTQFP100 are documented in Table 54 (DocID027866 Rev 5), with θJA = 28.5 °C/W under standard JEDEC 2-layer board conditions.
Does SPC572L64E3BC6AR support CAN FD?
No. It integrates two classical M_CAN modules compliant with ISO 11898-1 (CAN 2.0B), supporting bit rates up to 1 Mbps. CAN FD capability is not implemented in this silicon revision; users requiring CAN FD should evaluate the SPC58NG or SPC574K families.
How is EEPROM emulation implemented in the 1568 KB flash?
ST's dedicated Boot Assist Flash (BAF) region and RWW (Read-While-Write) flash architecture enable 32 KB of emulated EEPROM using wear-leveling algorithms and atomic page erase/write routines. This is managed by ST's SPC5 Flash Driver Library (v3.0+), not hardware EEPROM.
Can the GTM101 module operate independently of the CPU core?
Yes. GTM101 is a fully autonomous timer subsystem with its own clock domain, memory, and microcode engine. It executes preloaded timing sequences (e.g., PWM generation, input capture, time-triggered communication) without CPU intervention, reducing latency and freeing the e200z2 core for higher-level control tasks.
