Product details

16 MHz STM8 core with EnergyLite architecture

The STMicroelectronics STM8L101F1U6ATR is an 8-bit microcontroller from the STM8L EnergyLite series, built around a 16 MHz STM8 core.

Memory and peripheral budget for control-loop tasks

With 2 KB Flash and 1.5 KB RAM, this MCU targets firmware footprints typical of sensor readout, simple motor commutation, or IR remote decoding. The 18 GPIOs, combined with I²C, SPI, and UART, give enough headroom to interface with a small display, a few sensors, and a serial link without needing external expanders.

Active lifecycle — no near-term obsolescence concern

For supply assurance, we source this part through authorized distribution channels and can quote current pricing and availability against an RFQ.

Frequently asked questions

How do I get current pricing and availability for STM8L101F1U6ATR?

We source the STM8L101F1U6ATR through authorized distribution channels. Submit an RFQ through this page, and we will confirm current pricing and availability at quote time — no obligation.

What is STM8L101F1U6ATR's listed speed?

The core runs at 16 MHz, which is the maximum clock frequency for this STM8L EnergyLite device. At this speed the internal flash requires no wait states, keeping instruction execution deterministic for real-time control loops.
