The 48-LQFP package brings out 41 I/O lines, which is generous for the footprint and leaves room for parallel peripherals.
ST lists the STM8L151C4T3 as active product status.
The 48-LQFP (7x7 mm) is a fine-pitch surface-mount package with 0.5 mm lead pitch. The 41 I/O count is high for the package size, so fan-out routing on a two-layer board needs careful trace spacing.
The STM8L151C6 (with 32 KB Flash) is pin-compatible in the same 48-LQFP footprint and shares the same peripheral set. The main difference is program memory density — 16 KB vs 32 KB — so firmware that fits in the smaller Flash can move up without a board spin.
