Product details

The STM8L151G6U7TR is an 8-bit microcontroller from ST's STM8L EnergyLite family, built around the STM8 core running at 16 MHz.

Peripherals and analog integration

Connectivity includes I2C, SPI, UART/USART, and IrDA, plus a DMA controller for moving data without CPU overhead. The brown-out detect and POR circuits simplify power-on sequencing and reset management.

Housed in a 28-pin UFQFPN package (4x4 mm), this is a compact surface-mount device suited for space-constrained PCBs. The 26 I/O lines give enough flexibility for control signals, sensor interfaces, and display drivers in a small footprint.

For volume BOM lines, it can be qualified for production without last-time-buy risk.

Frequently asked questions

Where can I buy STM8L151G6U7TR available via RFQ confirmation?

This part is available to order through independent distribution.

What is the closest pin-compatible alternative to STM8L151G6U7TR?

Within the STM8L EnergyLite family, pin-compatible variants differ mainly in Flash and RAM size. The STM8L151G6U7TR sits at the 32 KB Flash / 2 KB RAM tier; higher-density siblings (e.g., 64 KB Flash) share the same 28-UFQFPN footprint but require firmware adjustment for the larger memory map.
