STM32MP157AAD3

The STM32MP157AAD3 from STMicroelectronics is a microprocessor for embedded applications in the STM32MP157 series. It integrates a dual ARM® Cortex®-A7 core subsystem (2 cores, 32-bit) running at 209 MHz and an ARM® Cortex®-M4 coprocessor to support mixed application and real-time tasks.

Designed for compact embedded designs, the device provides on-chip support for multiple memory types, display interfaces, Ethernet, USB, CAN and hardware security (ARM TZ), alongside graphics acceleration and a wide operating temperature range for demanding environments.

Key Features

• Core and Coprocessor  Dual ARM® Cortex®-A7 32-bit cores (2-core) at 209 MHz with an ARM® Cortex®-M4 coprocessor for combined application and real-time processing.
• Memory Controllers  Supports DDR3, DDR3L, LPDDR2 and LPDDR3 memory types to match performance and power targets for different system designs.
• Display and Graphics  Integrated display interface controllers including HDMI-CEC and LCD plus graphics acceleration for user interfaces and multimedia.
• Connectivity  Ethernet options including 10/100 Mbps and GbE, multiple USB 2.0 ports and USB 2.0 OTG+PHY, and CAN for flexible I/O and networking.
• Security  Hardware security support with ARM TrustZone (ARM TZ) for secure execution and trusted software domains.
• Package and Mounting  Supplied in a 257-TFBGA (10×10) package with surface-mount mounting for compact board layouts.
• Operating Range and Compliance  Wide operating temperature range from -40 °C to 125 °C and RoHS compliant.

Typical Applications

• Embedded Systems  General embedded control and application processing that benefit from dual Cortex-A7 cores and an M4 coprocessor.
