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).
