Product details

16 MHz STM8 core with EnergyLite power profile

The STM8L151G6U7: 8-bit MCU, STM8 core at 16 MHz, 32 KB Flash, 2K x 8 RAM, 1K x 8 EEPROM. Supply range 1.8 V to 3.6 V with brown-out detect and POR.

Industrial temperature range and active lifecycle

Rated for -40°C to 105°C, this MCU suits outdoor telecom cabinets, engine-bay modules, and factory-floor controllers where the ambient can swing. The product status is Active — no end-of-life notice or last-time-buy pressure on the horizon. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.

Connectivity and peripheral set

I²C, SPI, UART/USART, and IrDA cover the common serial buses for sensor modules, displays, and wireless add-ons. The internal oscillator eliminates the external crystal for many applications — though for precision timing (e.g., CAN bit timing or high-accuracy RTC), an external source may still be needed. PWM outputs and a watchdog timer round out the control-oriented peripheral set.

Frequently asked questions

Is STM8L151G6U7 obsolete or still active?

The STM8L151G6U7 is listed as Active in production status — no discontinuation notice or last-time-buy window is in effect.

Does STM8L151G6U7 require an external crystal?

No — the MCU includes an internal oscillator, so an external crystal is not required for basic operation. For applications needing precise timing (e.g., high-accuracy RTC or CAN), an external source may still be used.

What is the operating temperature range of STM8L151G6U7?

The operating temperature range is -40°C to 105°C, covering industrial and extended-temperature environments.

What is the pinout of STM8L151G6U7?

The part comes in a 28-UFQFPN package (4x4 mm) with 26 I/O lines. The exact pinout is defined in the STM8L151G6 datasheet; the package is a standard UFQFPN-28 footprint.
