• Arm TrustZone technology with dedicated security peripherals and tamper pins
• Hardware cryptographic acceleration including ECDSA, HASH, and RNG
• Flexible external memory controller supporting various DDR standards

Microprocessors Applications

• Industrial automation and PLC systems
• Smart metering and data concentrators
• Point-of-sale (POS) terminals and cash registers
• Electric vehicle charging infrastructure

Microprocessors Procurement Notes

Verify the specific package variant (TFBGA289 or TFBGA320) required for your design, as the 'A' suffix in the part number typically denotes basic security features without certified secure boot capabilities. Confirm RoHS compliance status and check for any recent PCN notifications regarding assembly sites or marking changes before finalizing procurement orders.

Microprocessors Selection Notes

Select this component when a cost-effective single-core MPU solution is needed for Linux or RTOS-based applications requiring moderate performance. It is suitable for designs that do not require the heterogeneous processing of a Cortex-M4 coprocessor found in the STM32MP15x series. Ensure the application can leverage the available GPIO count and peripheral set for system integration.

Microprocessors Part Context

This device belongs to the STM32MP13x product line within the broader STM32MP1 microprocessor portfolio. It is designed to optimize energy consumption and reduce costs while offering entry-level security for embedded systems. The series targets applications demanding reliable connectivity and sufficient processing power for standard embedded tasks without the complexity of multi-core architectures.

Microprocessors Replacement Considerations

Direct replacements within the same family include the STM32MP133CAF3 (certified security), STM32MP133DAF3 (higher frequency), and STM32MP133FAF3 (certified security, higher frequency). For more advanced features, consider the STM32MP15x series which adds a Cortex-M4 core and GPU.
