It carries 2 MB of Flash and 640 KB of SRAM, which puts it in the high-density tier of the family — enough room for a full RTOS, a TCP/IP stack, and a sensor-fusion library without external memory.
It uses an ARM Cortex-M4 core running at 120 MHz, with single-cycle multiply and hardware floating-point unit for DSP workloads.
Both are part of the STM32L4S series in the same 100-LQFP package, so they are pin-compatible. The STM32L4S7VIT6 offers the full 2 MB Flash and 640 KB SRAM, while the STM32L4S5VIT6 has less memory — check the specific memory and peripheral differences in the STM32L4S family reference manual before substituting.
