Product details

Peripheral set and connectivity — what the 83 I/O lines enable

The STM32L4Q5VGT6: 83 I/O lines in a 100-LQFP package; the peripheral list includes an LCD controller, EBI/EMI bus for external memory, and multiple serial interfaces.

Data converters and analog

The on-chip data converters include a 16-channel 12-bit ADC and a 2-channel 12-bit DAC. For a mixed-signal control board — say, a motor drive with current sensing or a battery monitor — these reduce the external analog front-end count.

Lifecycle and sourcing posture

For dual-sourcing or supply resilience, the STM32L4 series includes pin-compatible density variants (e.g., 512 KB Flash / 256 KB SRAM options in the same 100-LQFP footprint) that share the same peripheral map, though the exact alternate order code depends on your memory and temperature requirements.

Frequently asked questions

Does STM32L4Q5VGT6 have a built-in LCD controller?

Yes, the peripheral list includes an LCD controller, along with PWM, watchdog timers, brown-out detect/reset, DMA, and POR. This makes it a candidate for local display interfaces without an external display driver IC.

What are the alternatives to STM32L4Q5VGT6?

Within the STM32L4 series, pin-compatible variants with lower Flash and SRAM densities (e.g., 512 KB Flash / 256 KB SRAM) share the same 100-LQFP footprint and peripheral set. The exact alternative depends on your memory budget and temperature grade — the base product number STM32L4Q5 covers this density tier.
