Product details
Overview
SPC572L64E3BC6AY from STMicroelectronics is a 32-bit Power Architecture® VLE-compliant automotive MCU with one e200z2 CPU core, 1568 KB on-chip RWW flash (including 32 KB EEPROM emulation), 64 KB SRAM, and AEC-Q100 qualification for powertrain control. It integrates GTM101 (72-channel intelligent timer), dual M_CAN, FEC Ethernet, SENT, LINFlexD, DSPI, and 12-/16-bit ADCs - deployed in gasoline/diesel engine control units.
For engineers reviewing the SPC572L64E3BC6AY datasheet, SPC572L64E3BC6AY pinout, SPC572L64E3BC6AY application, or SPC572L64E3BC6AY equivalent, key selection criteria include ASIL-A compliance, eTQFP100 packaging, 1568 KB flash with EEPROM emulation, GTM101 timer capability, and dual M_CAN + FEC support for powertrain domain integration.
Technical Context
The SPC572L64E3BC6AY implements a single-issue e200z2 core compliant with Power Architecture® VLE, supporting single-precision floating-point operations and system-level safety features including SMPU, self-test, and ISO 26262 ASIL-A design intent. Its clock architecture centers on a single PLL generating stable domains for both core and peripherals.
Peripheral integration includes GTM101 - a programmable, event-driven timer subsystem with 16 input and 56 output channels - alongside three 12-bit SAR ADCs and one 16-bit Sigma-Delta ADC with decimation unit, enabling high-resolution sensor acquisition for closed-loop engine control.
