MANUFACTURER PART RECORD

STM32U585AII6

STM32U585AII6 is an STMicroelectronics Cortex-M33 microcontroller with FPU and TrustZone, up to 160 MHz and 2 MB dual-bank flash. SRAM capacity is 786 KB with ECC off or 722 KB with ECC enabled on up to 322 KB. AII6 identifies UFBGA-169, a 7 × 7 mm body with 0.5 mm pitch, −40°C to +85°C ambient grade and tray packing. This code has no Q suffix: it is the non-SMPS version, not the dedicated SMPS pinout. Confirm the supply circuit, ball map, memory configuration and security provisioning before approving a substitute. Reviewed against ST DS13086 Rev 10 and exact-code product-table rows.

Sourcing note

Confirm ordering suffix, package, temperature grade, programming and date-code requirements.

Before you request a quote

Do not silently add the Q suffix
AII6 and AII6Q differ in power-option pinout. Confirm the approved supply circuit and ball map; an SMPS family feature does not make every ordering code an SMPS version.
Budget memory for the selected configuration
Account for SRAM ECC configuration rather than assuming all headline RAM is available unchanged. Confirm firmware, security provisioning, full suffix and tray requirements before quotation; TrustZone support alone does not certify a finished product.
