Product details

STM8L151M8T6TR — 8-bit MCU for low-power control

Connectivity options include I²C, IrDA, SPI, and UART/USART.

16 MHz core and 64 KB Flash — sizing the control loop

The 16 MHz clock rate is typical for 8-bit MCUs handling sensor polling, motor commutation, or serial protocol bridges. Combined with 64 KB of Flash, this part fits firmware images that include a modest RTOS or a state-machine-based application with room for field-upgrade staging. The 4 KB RAM supports moderate data buffers; the 2 KB EEPROM allows parameter storage without external memory.

Frequently asked questions

Is STM8L151M8T6TR an exact replacement for STM8L151M8T6?

The STM8L151M8T6TR is the Tape & Reel packaged variant of the base STM8L151M8T6. The die, firmware, and electrical specifications are identical. The only difference is the shipping medium: the TR suffix denotes reel packaging for pick-and-place, while the base part number typically ships in trays or tubes. For a one-to-one BOM substitution, verify the package (80-LQFP) and temperature range match your assembly process.

Is STM8L151M8T6TR compatible with ST-Link programmer?

Yes. The STM8L151M8T6TR uses the standard STM8 SWIM debug interface, which is supported by ST-Link programmers (ST-LINK/V2, ST-LINK/V3, and the ST-Link embedded on STM8 discovery boards). The SWIM pin is on the 80-LQFP package; refer to the STM8L151x8 datasheet for the exact pin location.
