STMicroelectronics STM32L496AGI6P

Overview

STM32L496AGI6P from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, delivering 100 DMIPS at up to 80 MHz, featuring 1 MB flash, 320 KB SRAM, USB OTG FS, hardware HASH (SHA-256), and integrated SMPS support. It targets battery-powered IoT edge nodes, portable medical devices, and energy-harvesting sensor hubs requiring long runtime and rich peripheral integration.

For engineers reviewing the STM32L496AGI6P datasheet, STM32L496AGI6P pinout, STM32L496AGI6P application, or STM32L496AGI6P equivalent, key selection criteria include its 25 nA shutdown current, dual-bank read-while-write flash, Chrom-ART Accelerator for GUI rendering, 2x CAN 2.0B interfaces, and support for external static memories via FSMC - all in a 132-pin UFBGA package with 5 V-tolerant I/Os.

Technical Context

The device implements an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from flash memory, paired with a Memory Protection Unit (MPU) and interconnect matrix for deterministic peripheral arbitration. Its power architecture integrates three voltage regulators (LDO/SMPS/bypass), enabling dynamic voltage scaling across seven low-power modes - including Stop 2 (2.57 µA) and Standby with RTC (426 nA).

Peripherals are organized around dual AHB/APB buses: two SAIs support I²S/TDM audio streaming; four I²C FM+ interfaces operate up to 1 Mbit/s; six USART/LPUARTs include LIN, IrDA, and modem support; and the DCMI interface handles 8–14-bit camera input at up to 32 MHz (B&W). The embedded HASH engine performs SHA-256 in hardware without CPU intervention.

FAQ

What is the maximum operating temperature range for STM32L496AGI6P?

The STM32L496AGI6P is qualified for industrial operation from –40 °C to +85 °C, with extended variants supporting up to +125 °C. This rating applies across all low-power modes and peripheral functions, including RTC and backup registers, as verified in DS11585 Rev 20 Section 6.3.1.

Does STM32L496AGI6P support external memory interfaces?

Yes - it integrates a Flexible Static Memory Controller (FSMC) supporting SRAM, PSRAM, NOR, and NAND memories with address/data multiplexing, plus a dual-flash QUADSPI interface for high-speed serial flash. Both interfaces are accessible in Run and Sleep modes per Section 3.40 and 3.41 of the datasheet.

How many independent power domains does STM32L496AGI6P support?

It supports three independent power domains: VDD/VSS (core/digital), VDDA/VSSA (analog), and VDDIO2 (I/O voltage down to 1.08 V). This enables mixed-voltage operation - for example, 1.2 V core with 3.3 V sensors - and reduces leakage in partial-power-down scenarios.

Can the hardware HASH accelerator perform SHA-256 on arbitrary data blocks?

Yes - the HASH peripheral processes data blocks of any size (1–65535 bytes) in DMA or polling mode, generating SHA-256 digests without CPU involvement. It supports continuous hashing across multiple buffers and includes message padding logic per FIPS PUB 180-4, as documented in Section 3.27.
