STMicroelectronics STM32U5F9BJY6QTR

Overview

STM32U5F9BJY6QTR from STMicroelectronics is an Arm® Cortex®-M33 ultra-low-power microcontroller with TrustZone®, 160 MHz max CPU frequency, 4 MB flash (ECC), 3 MB SRAM (ECC configurable), and integrated Neo-Chrom GPU2D, MIPI® DSI, LTDC, JPEG codec, and hardware security accelerators. It targets secure, graphics-rich IoT edge nodes, portable medical devices, and industrial HMIs requiring sub-μA Stop modes and autonomous peripheral operation.

For engineers reviewing the STM32U5F9BJY6QTR datasheet, STM32U5F9BJY6QTR pinout, STM32U5F9BJY6QTR application, or STM32U5F9BJY6QTR equivalent, key selection criteria include LPBAM-enabled peripheral autonomy in Stop 2/3, VBAT-retained RTC + 2 KB backup SRAM, 151 GPIOs (5V-tolerant), dual Octo-SPI interfaces, and TrustZone-secured boot and memory partitioning.

Technical Context

This MCU implements a dual-cache Arm Cortex-M33 core with MPU, FPU, and DSP extensions, supported by 32 KB instruction cache (ICACHE) and 16 KB data cache (DCACHE) for zero-wait-state execution at 160 MHz. Its FlexPowerControl architecture enables 150 nA Shutdown mode and 480 nA Standby with RTC via dedicated low-power regulators and dynamic voltage scaling.

The device integrates three domain-specific accelerators: Neo-Chrom VG (GPU2D) for vector graphics and texture mapping, Chrom-ART (DMA2D) for 2D graphic composition, and hardware JPEG codec supporting encode/decode up to Full HD resolution - all accessible while CPU remains in low-power states.

FAQ

What is the maximum operating temperature range for STM32U5F9BJY6QTR?

The STM32U5F9BJY6QTR is rated for industrial operation from –40 °C to +85 °C ambient temperature. This range is validated per JEDEC JESD47 and applies across all low-power modes, flash programming, and peripheral operation - confirmed in Section 5.3.1 of DS14395 Rev 4.

Does STM32U5F9BJY6QTR support hardware JPEG encoding and decoding?

Yes - it integrates a dedicated hardware JPEG codec supporting both encoding and decoding of baseline JPEG images up to Full HD (1920×1080) resolution. The codec operates independently of the CPU and can be triggered via DMA or LPBAM, as detailed in Section 3.22 of the datasheet.

How many wake-up pins are available in Standby mode?

STM32U5F9BJY6QTR supports 24 dedicated wake-up pins in Standby mode, including all GPIOs configured as EXTI lines and select analog comparator outputs. Wake-up latency from Standby is ≤5.5 µs, verified in Section 5.3.7 of DS14395 Rev 4.

Is the WLCSP208 package RoHS and REACH compliant?

Yes - the WLCSP208 package for STM32U5F9BJY6QTR meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. It is also ECOPACK2 certified, with lead-free solderability and halogen-free molding compound, as stated in Section 6.2 of the datasheet.
