STM8L151R8T6

STM8L151R8T6 is a low‑power 8‑bit microcontroller from STMicroelectronics, part of the STM8L family designed for battery-powered and energy-efficient applications. It uses the STM8 CPU core and supports ultra‑low power operation with multiple sleep modes and a wide voltage range (roughly 1.65–3.6 V). The R8T6 variant provides on‑chip Flash and RAM (memory sizes vary by variant) and a set of common peripherals: USART/UART, SPI, I2C, a 12‑bit ADC, multiple timers (8/16‑bit), watchdog, and RTC; some packages also include an LCD driver. The device comes in the T6 package and is supported by ST’s development tools (Cosmic/IAR/STVD) and ST‑Link for programming/debugging. It’s suitable for compact, low‑power controllers in sensors, meters, wearables, and portable instrumentation. For exact specs (flash RAM sizes, available peripherals, and pinout), refer to the official datasheet.
