Product details
Overview
STM32L476JGY6VTR from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, delivering 100 DMIPS at 80 MHz, featuring 1 MB flash, 128 KB SRAM, USB OTG FS, LCD controller, and integrated SMPS support. It operates from 1.71–3.6 V across –40 °C to 105 °C and achieves 39 µA/MHz in SMPS-run mode - ideal for battery-powered medical sensors and portable industrial HMI displays.
For engineers reviewing the STM32L476JGY6VTR datasheet, STM32L476JGY6VTR pinout, STM32L476JGY6VTR application, or STM32L476JGY6VTR equivalent, key selection criteria include verified low-power run/stop modes (39 µA/MHz SMPS, 420 nA Stop 2), dual 12-bit DACs with sample-and-hold, hardware-accelerated LCD driving (8×40), and CAN 2.0B + USB OTG FS coexistence in a UFBGA144 package.
Technical Context
The device integrates an Adaptive Real-time Accelerator (ART™) enabling zero-wait-state execution from flash at 80 MHz, paired with a memory protection unit (MPU) and dual-bank read-while-write flash for secure firmware updates. Its power architecture includes three independent voltage regulators (LDO/SMPS/VREFBUF) and FlexPowerControl logic managing 7 low-power modes - including Shutdown (30 nA), Standby with RTC (420 nA), and Stop 2 with LPUART wake-up.
Analog subsystems are isolated via independent supply domains: three 12-bit ADCs (5 Msps, 16-bit oversampling), two rail-to-rail op-amps with programmable gain, two ultra-low-power comparators, and a 24-channel touch-sensing controller (TSC). Clocking uses four independent sources - including auto-trimmed MSI (±0.25%) and dual PLLs for system/USB/audio domains.

FAQ
What is the maximum operating temperature range for STM32L476JGY6VTR?
The STM32L476JGY6VTR is qualified for industrial operation from –40 °C to +105 °C ambient temperature, as confirmed in Section 6.3.1 of DS10198 Rev 11. This rating applies to all UFBGA144 variants and is validated under full peripheral activation, including LCD and USB OTG FS operation.
Does STM32L476JGY6VTR support external SMPS integration, and how is it configured?
Yes - the device includes dedicated VDD12 and VDD12_IO pins and internal SMPS control logic. When an external switched-mode supply delivers 1.1 V to VDD12, the MCU automatically switches from LDO to SMPS mode, reducing active current to 39 µA/MHz. Configuration is handled by the PWR_CR2 register's SWS bit and requires external circuitry per AN4865.
Can the LCD controller drive a 4×44 segment display without external components?
Yes - the integrated LCD controller includes a programmable step-up converter that generates required bias voltages internally. Driving a 4×44 multiplexed display only requires connecting VLCD and VLCD_CAP pins per Section 3.21; no external charge pump or DC-DC converter is needed.
How many independent power domains does STM32L476JGY6VTR support for analog peripherals?
The MCU provides three isolated power domains: VDDA (analog supply, 1.62–3.6 V), VDDIO2 (I/O supply, 1.08–3.6 V), and VREF+ (reference voltage input). This allows simultaneous operation of 12-bit ADCs, DACs, op-amps, and comparators with independent noise filtering and voltage scaling - critical for precision metrology applications.
