Product details

What the 120 MHz Cortex-M4 buys you in this STM32L4 variant

The Cortex-M4 floating-point unit handles DSP math without a software library.

Peripheral set and connectivity — what the 140 I/O can connect to

With 140 I/O lines and a 169-UFBGA (7x7 mm) package, this MCU can drive a parallel LCD, an external memory bus via EBI/EMI, and multiple serial buses simultaneously.

Data converters and package — integration details

The device integrates two 12-bit DACs and sixteen 12-bit ADC channels, covering analog front-end needs for current sensing, temperature monitoring, or audio input without an external converter.

For volume commitments, the base product number STM32L4Q5 covers multiple density and package variants, so a single qualification covers the family.
