Product details

Active production, 16 MHz 8-bit MCU in a 20-TSSOP footprint

The STM8L051F3P6TR is an 8-bit microcontroller from STMicroelectronics' STM8L EnergyLite series, built around the STM8 core and clocked at 16 MHz.

Memory and peripheral fit for sensor-node and control designs

With 8 KB of Flash and 1 KB of RAM, this MCU targets applications that don't need a large firmware image — think sensor readout, simple motor control, or IR remote decoding.

Package and supply: 20-TSSOP with 18 I/Os

Housed in a 20-lead TSSOP (4.40 mm body width), this part gives you 18 general-purpose I/O lines — enough for a small keypad, a few LED indicators, and a serial interface.

Sourcing: active lifecycle, quoted to order

For current pricing and availability, we source and quote against an RFQ — no automated stock figure here, but we can confirm lead times and pricing at quote time. The STM8L051F3P6TR is the tape-and-reel variant; if you need the tube-packaged version for prototyping, look at the base part STM8L051F3P6 (without the TR suffix).

Frequently asked questions

Where can I buy STM8L051F3P6TR?

Submit a request for current pricing and availability.

Can STM8L051F3P6TR replace STM8L051F3P6?

The STM8L051F3P6TR is the tape-and-reel packaged version of the same die as the STM8L051F3P6 (which typically ships in tubes). Electrically and functionally they are identical — the only difference is the shipping medium. If your assembly line feeds from tape, the TR variant is the correct ordering code.

What is STM8L051F3P6TR's listed speed?

The core processor runs at 16 MHz, which is the maximum clock speed for this STM8L EnergyLite device.
