The STM32L476VGT6 from STMicroelectronics is an ultra-low-power 32-bit MCU from the STM32L4 family, based on the high-performance Arm Cortex-M4 core running at up to 80MHz. The core integrates a single-precision floating-point unit, DSP instructions, and a Memory Protection Unit for embedded control and signal-processing applications.
The exact STM32L476VG configuration integrates 1MB of Flash and 128KB of SRAM. The Flash supports dual-bank Read-While-Write operation and multiple protection mechanisms, while the 100-pin device also supports an external static-memory interface and Quad-SPI external Flash connectivity.
Analog resources include up to three 12-bit ADCs operating at up to 5Msps, hardware oversampling for resolutions up to 16 bits, two 12-bit DAC channels, two operational amplifiers, and two ultra-low-power comparators.
Communication interfaces include three I²C, three SPI, three USART, two UART, one low-power UART, two SAI, CAN 2.0B, SDMMC, USB OTG 2.0 Full-Speed, and SWPMI. The device also includes a Quad-SPI memory interface.
An integrated LCD controller supports configurations up to 8 × 40 or 4 × 44 segments, while up to 24 capacitive-sensing channels can be used for touch keys, sliders, and rotary touch controls.
Additional system resources include multiple 16-bit and 32-bit timers, low-power timers, watchdogs, a 14-channel DMA controller, true random-number generator, CRC unit, and 96-bit unique device ID.
The STM32L476 family operates from a 1.71V-to-3.6V supply and provides multiple ultra-low-power operating modes. ST lists typical figures as low as 30nA in Shutdown, 120nA in Standby, 1.1µA in Stop 2, and approximately 100µA/MHz in Run mode, depending on configuration.
The exact STM32L476VGT6 uses a 100-pin LQFP package measuring 14 × 14 × 1.4mm. It is an industrial-grade device with an operating-temperature range of −40°C to +85°C, supplied in tray packaging, and classified as ECOPACK2 compliant.
ST currently lists the STM32L476VGT6 as Active and in volume production, with a 10-year longevity commitment.
