Product details

STM8AL3146UCY — an 8-bit automotive MCU heading into its last-time-buy window

It runs at 16 MHz and packs 16 KB of Flash program memory, 2K x 8 of RAM, and 1K x 8 of EEPROM — enough for a body-control module, a LIN-bus node, or a sensor hub that needs to log calibration data without external storage.

Peripheral set — analog and serial interfaces for mixed-signal control

New designs should target a pin-compatible or functionally equivalent replacement within the STM8A family — the base product number STM8 covers a range of density and peripheral options that share the same core architecture and toolchain.
