STM32MP157FAC1

STM32MP157FAC1 is an STMicroelectronics STM32MP1 microprocessor: dual 800 MHz Arm Cortex-A7 plus a Cortex-M4 and a 3D GPU (OpenGL ES 2.0), in a 361-ball TFBGA. It is ST's Linux-MPU answer for industrial HMI — the A7 pair runs the OpenSTLinux distribution for rich touch interfaces while the M4 runs real-time tasks under STM32CubeMP1, and the on-chip GPU removes the external graphics chip from mid-range panels; Gigabit Ethernet, dual FDCAN and the STPMIC1 companion-PMIC ecosystem shorten power-tree design. Heat evidence: ST's flagship MPU family — the STM32MP157F-DK2 Discovery kit is listed Active and stocked on ST's own online store, and the OpenSTLinux mainline ecosystem draws steady industrial design activity. Selection advice: the FAC1 suffix denotes the TFBGA-361 package — the FAA1 LFBGA-448 is a different footprint, not a drop-in; the F speed grade is the 800 MHz variant and 800 MHz operation is temperature-range limited per the datasheet, so confirm thermal assumptions for wide-temperature designs. Parameters verified against STMicroelectronics documentation.
