Product details
Overview
STM32L496ZGT6TR from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, 80 MHz max frequency, 1 MB flash, 320 KB SRAM, and integrated USB OTG FS, audio SAI, HASH (SHA-256), and external SMPS support. It delivers 100 DMIPS and operates from 1.71–3.6 V across –40 °C to 125 °C, targeting battery-powered industrial sensors and portable medical devices requiring secure, real-time processing with sub-µA standby.
For engineers reviewing the STM32L496ZGT6TR datasheet, STM32L496ZGT6TR pinout, STM32L496ZGT6TR application, or STM32L496ZGT6TR equivalent, key selection criteria include its dual-bank flash with read-while-write, 2.57 µA Stop 2 mode, 37 µA/MHz SMPS-run efficiency, and hardware-accelerated crypto for firmware integrity in constrained-edge deployments.
Technical Context
The device integrates an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from flash at 80 MHz, alongside a multi-AHB interconnect matrix for concurrent peripheral access. Its power architecture includes three voltage regulators (LDO/SMPS/bypass), brownout reset in all modes except shutdown, and FlexPowerControl enabling dynamic voltage scaling between Run, Stop, and Standby states.
Peripherals are partitioned across low-power domains: two LPTIMs remain active in Stop mode; RTC, backup registers, and 32-bit tamper-protected SRAM persist in VBAT mode; and the Chrom-ART Accelerator (DMA2D) offloads graphics rendering independently of CPU load-critical for GUI-enabled HMI applications with strict energy budgets.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32L476RG | 512 KB flash, 128 KB SRAM, no external SMPS interface, no SAI, no Chrom-ART | Lacks audio interface and graphics acceleration - unsuitable for voice-enabled or GUI HMIs | Select when cost-sensitive designs require only basic connectivity (USB, CAN) and lower memory footprint |
| STM32U575ZIT6 | 1 MB flash, 512 KB SRAM, Arm Cortex-M33 with TrustZone, 1.4 µA Stop mode, no DCMI or SAI | Higher security (TrustZone), deeper sleep, but lacks camera/audio interfaces - better for secure IoT gateways than multimedia edge nodes | Select for PSA Certified Level 3 applications needing hardware root-of-trust, not for sensor fusion with imaging/audio |
Compared with STM32L476RG, the STM32L496ZGT6TR adds SAI, Chrom-ART, and SMPS control for audio/HMI systems; versus STM32U575ZIT6, it trades TrustZone for richer analog/peripheral integration essential in medical and industrial sensing - making it optimal where mixed-signal capability outweighs pure security certification needs.

FAQ
What is the maximum operating temperature range for STM32L496ZGT6TR?
The STM32L496ZGT6TR is qualified for operation from –40 °C to +125 °C ambient temperature, meeting industrial and extended-temperature requirements. This rating applies to all LQFP144-packaged variants and is validated per JEDEC JESD47 stress testing - enabling deployment in harsh environments like motor control enclosures or outdoor utility infrastructure.
Does STM32L496ZGT6TR support hardware encryption beyond SHA-256?
No - the STM32L496ZGT6TR integrates only the HASH peripheral for SHA-256 acceleration. It does not include AES, DES, or PKA engines. For asymmetric cryptography or bulk encryption, external secure elements or software libraries running on the Cortex-M4 FPU must be used, though the 100 DMIPS performance allows efficient ChaCha20 or AES-CTR implementation in RAM-constrained contexts.
Can the external SMPS interface drive third-party DC-DC converters?
Yes - the VDD12 pin provides direct control and feedback monitoring for external SMPS ICs compatible with ST's reference design (e.g., ST1PS01). The interface supports enable/disable signaling, voltage regulation feedback, and fault reporting via dedicated GPIOs (e.g., VDD12_EN, VDD12_OK), allowing interoperability with industry-standard buck controllers that accept 3.3 V logic-level control signals.
How many independent power domains does STM32L496ZGT6TR support?
The device implements four independent power domains: VDD/VSS (core/digital), VDDA/VSSA (analog), VDDIO2 (I/O bank 2), and VBAT (backup). Each domain has dedicated regulators and voltage monitors - enabling simultaneous operation of 1.08 V sensors, 3.3 V communication interfaces, and 1.8 V analog circuits while maintaining RTC functionality during main power loss.
