It packs 16 KB of Flash program memory, 2 KB of RAM, and 1 KB of EEPROM in a 32-LQFP package with 30 I/O lines. For timing-critical serial buses (I²C, SPI, UART) the internal RC is trimmed to ±1 % accuracy over temperature, but if you need tighter ppm for a CAN or USB clock, budget an external resonator. ST lists this part as Active. That means no end-of-life notice in the pipeline, no last-time-buy scramble. You can design it into a production BOM today and expect standard distribution availability for the next several years. Not rated for under-hood or downhole (no 125°C or AEC-Q100 tag), so if your design sees sustained junction temps above 85°C, look at the extended-temp STM8L151x6 variants.","metaTitle":"STM8L151K4T6TR STM8L EnergyLite 8-bit MCU, 16 MHz, 32-LQFP","metaDescription":"STM8L151K4T6TR STMicroelectronics 8-bit MCU, 16 MHz, 16 KB Flash, 2 KB RAM, 1 KB EEPROM, 30 I/O, 12-bit ADC/DAC, -40 to 85°C.

The only difference is the shipping medium: the TR suffix designates Tape & Reel for automated assembly, while the base code STM8L151K4T6 typically ships in tray or tube.
