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."},{"question":"What is STM32L486ZGT3's listed speed on this component line?","answer":"The core runs at 80 MHz."},{"question":"Where can I buy STM32L486ZGT3?","answer":"The STM32L486ZGT3 is available through independent distribution.
