Product details

The STM32L476JGY7TR is an STMicroelectronics 32-bit ARM Cortex-M4 MCU from the STM32L4 ultra-low-power series, clocked at 80 MHz with a single-precision FPU and DSP instructions. The industrial temperature range from -40°C to 105°C means this MCU can live in an outdoor telecom cabinet or a motor-drive enclosure without derating worries.

80 MHz Cortex-M4 — what the clock buys you

The 80 MHz core runs a real-time control loop with floating-point math or a basic DSP filter chain.

This MCU carries a rich peripheral set: CANbus, USB OTG, multiple SPI/I²C/UART interfaces, plus a Quad-SPI for external Flash and an LCD driver for segment displays. The 16-channel 12-bit ADC and dual 12-bit DAC cover analog front-end needs without an external converter. Brown-out detect and a watchdog timer are built in — useful for fail-safe designs in industrial or automotive-adjacent environments.

Frequently asked questions

What is the closest pin-compatible alternative to STM32L476JGY7TR?

The STM32L476RGT6 (LQFP-64) and STM32L476VGT6 (LQFP-100) share the same 1 MB Flash / 128 KB RAM Cortex-M4 core and peripheral set, but in different packages. For a true WLCSP pin-compatible swap, look at the STM32L476JGY6TR (same 72-WLCSP, same memory) — the 'Y6' suffix indicates a slightly different temperature grade or revision; verify the operating temperature matches your requirement.

What compliance documentation is available for STM32L476JGY7TR?

STMicroelectronics provides RoHS and REACH compliance declarations for this part as standard. The WLCSP package is lead-free and halogen-free per ST's green packaging policy. Full compliance certificates are available from the manufacturer's product page or through the distributor upon request.
