Product details

Core and memory headroom for a mixed-signal design

The STM32L476ZGT6TR: That Flash-to-RAM ratio suits applications running a moderate codebase alongside a real-time OS or a bare-metal scheduler — the 1 MB holds the firmware and a file system, while the 128 KB leaves room for the stack, heap, and a few large buffers without external memory.

Connectivity and analog chain

This part carries CANbus, USB OTG, QSPI, SAI, and multiple UART/USART/SPI/I²C interfaces — enough to bridge a sensor array, a display, and a fieldbus gateway from one chip. The 24-channel 12-bit ADC and dual 12-bit DAC let it handle analog front-end tasks directly, without an external converter.

Frequently asked questions

What is the closest pin-compatible alternative to STM32L476ZGT6TR?

Within the STM32L4 series, the STM32L4xx family shares the same 144-LQFP footprint. The STM32L496ZGT6 offers a similar pinout with additional SRAM, while the STM32L4R5ZGT6 adds a higher-speed core. Verify the specific peripheral set and memory map against your firmware before swapping.

What is the speed of STM32L476ZGT6TR?

The STM32L476ZGT6TR runs at 80 MHz from its internal oscillator or an external clock source.

What compliance documentation does STMicroelectronics provide for STM32L476ZGT6TR?

The STM32L476ZGT6TR is ROHS3 compliant. STMicroelectronics provides a datasheet, reference manual, and application notes covering the full STM32L4 series.
