Compliance: RoHS 3 compliant

Package: 64‑LQFP (10 x 10 mm), surface‑mount

Key Advantages

Excellent energy efficiency from the STM32L4 ultra‑low‑power platform

512 KB Flash gives ample space for complex applications and OTA updates

Rich analog and digital I/O set in a compact 64‑pin package

Broad interface support (USB OTG, CAN, QSPI, SD/MMC) suits many designs without extra ICs

Industrial temperature range (−40°C to +85°C) for robust field use

Mature STM32 ecosystem: CubeMX configuration, HAL/LL drivers, widespread middleware and RTOS support

RoHS 3 compliance supports green, global markets

Packaging

Shipping format: Tape & Reel (TR) for automated assembly

Package type: 64‑LQFP (Low‑Profile Quad Flat Package), 10 x 10 mm body

Pin configuration: 64 leads, typical 0.5 mm pitch; up to 51 GPIOs available

Materials/finish: Lead‑free, RoHS‑compliant plastic encapsulation with plated copper leads (matte‑tin finish typical)

Mounting: Surface‑mount technology (SMT)

Thermal characteristics: Ambient operating −40°C to +85°C; thermal resistance depends on PCB and airflow—see datasheet for θJA/θJC and derating

Electrical properties (high level): 1.71–3.6 V supply, 80 MHz max core clock, integrated analog converters (ADC 16x12‑bit, DAC 2x12‑bit); see datasheet for I/O drive, ESD ratings, and absolute maximum ratings
