Product details

Dual-core asymmetric processing in a single BGA

The STM32MP157AAD3T is a dual-core microprocessor from STMicroelectronics' STM32MP1 series, combining a 650 MHz ARM Cortex-A7 application core with a 209 MHz ARM Cortex-M4 real-time coprocessor in a 257-TFBGA package.

The 257-TFBGA (10x10 mm) package with surface-mount assembly suits compact PCBs in motor drives, outdoor telecom, and engine-control modules.

Five USB 2.0 ports (two host, three OTG+PHY) cover multiple peripheral connections without external hub chips. The integrated Gigabit Ethernet MAC and 10/100 Mbps support industrial networking stacks. Additional interfaces include CAN, I²C, SPI, UART, MMC/SD/SDIO, SPDIF, and HDMI-CEC, which together address HMI panels, gateway appliances, and edge-compute nodes.

Security and graphics

ARM TrustZone (ARM TZ) provides a hardware-isolated secure environment for boot authentication, key storage, and secure firmware updates. The part includes graphics acceleration and an LCD display controller, making it suitable for embedded GUI applications without a separate GPU.

It is ROHS3 compliant.

Frequently asked questions

Is STM32MP157AAD3T lead-free?

Yes, the STM32MP157AAD3T is ROHS3 compliant, meaning it meets the lead-free and restricted-substance requirements of the RoHS directive.

Are there alternatives to STM32MP157AAD3T in the STM32MP1 family?

The STM32MP1 series includes multiple variants that differ in core frequency, graphics acceleration, and peripheral count. The closest pin-compatible alternatives are other STM32MP157 devices in the same 257-TFBGA package, which share the same footprint and memory controller options. For a specific cross-reference, compare the exact speed grade and feature set against the series ordering information.
