Product details

1 MB Flash + 128 KB SRAM — firmware headroom for complex stacks

The QSPI interface supports memory-mapped external Flash for code shadowing or data logging.

For a BOM line, that removes the single-source lifecycle risk that plagues older MCU families.

Frequently asked questions

What is the closest pin-compatible alternative to STM32L486ZGT3 in this component family?

Within the STM32L4 series, the STM32L496ZGT3 is a common cross-shop candidate. It shares the same 144-LQFP footprint and peripheral set but offers a larger 320 KB SRAM and a Chrom-ART graphics accelerator. The trade-off is slightly higher active current. Both are active and pin-compatible, so a board designed for one can accept the other with a firmware change.

What is STM32L486ZGT3's listed speed on this component line?

The core runs at 80 MHz.

Where can I buy STM32L486ZGT3?

The STM32L486ZGT3 is available through independent distribution. Submit an RFQ to confirm current pricing and availability — the part is sourced to order, not held on a shelf.
