Product details

It packs 8 KB of Flash program memory, 1 KB of RAM, and 256 bytes of EEPROM in a compact 20-TSSOP package with 18 I/O lines. This is a low-power part aimed at battery-operated or energy-sensitive applications — think portable instruments, sensor nodes, and simple control loops where every microamp matters.

For communication you get I²C, IrDA, SPI, and UART/USART — enough to talk to common sensors, displays, and serial memories without external glue. The 10-channel 12-bit ADC covers analog inputs like temperature or battery voltage monitoring.

Industrial temperature grade

The lifecycle record shows one source flags end-of-life hot while the manufacturer lists it as Active. We source this part through independent distribution and quote it to order against an RFQ.

Frequently asked questions

What is the closest pin-compatible alternative to STM8L151F3P6TR?

The STM8L151F3P6 is the tray/tube variant of the same die in the same 20-TSSOP package — functionally identical, just different shipping media. For a higher-density option, the STM8L151G3 parts in the same family share the STM8L EnergyLite architecture but check the pinout for your specific I/O and package requirements.

What is STM8L151F3P6TR's listed speed?

The core runs at 16 MHz, which delivers roughly 8-16 MIPS depending on instruction mix.
