Ultra-low-power device continuum

The ultra-low-power STM32L151x6/8/B and STM32L152x6/8/B devices are fully pin-to-pin

and software compatible. Besides the full compatibility within the family, the devices are part

of STMicroelectronics microcontrollers ultra-low-power strategy which also includes

STM8L101xx and STM8L15xx devices. The STM8L and STM32L families allow a

continuum of performance, peripherals, system architecture and features.

They are all based on STMicroelectronics ultra-low leakage process.

The ultra-low-power STM32L and general-purpose STM32Fxxxx families are pin-to-pin

compatible. The STM8L15xxx devices are pin-to-pin compatible with the STM8L101xx

devices. Please refer to the STM32F and STM8L documentation for more information on

these devices.

Performance

All families incorporate highly energy-efficient cores with both Harvard architecture and

pipelined execution: advanced STM8 core for STM8L families and ARM® Cortex®-M3 core

for STM32L family. In addition specific care for the design architecture has been taken to

optimize the mA/DMIPS and mA/MHz ratios.

This allows the ultra-low-power performance to range from 5 up to 33.3 DMIPs.

Shared peripherals

STM8L15xxx and STM32L1xxxx share identical peripherals which ensure a very easy

migration from one family to another:

• Analog peripherals: ADC, DAC and comparators

• Digital peripherals: RTC and some communication interfaces

Common system strategy

To offer flexibility and optimize performance, the STM8L15xx and STM32L1xxxx families

use a common architecture:

• Same power supply range from 1.65 V to 3.6 V, (1.65 V at power down only for

STM8L15xx devices)

• Architecture optimized to reach ultra-low consumption both in low power modes and

Run mode

• Fast startup strategy from low power modes

• Flexible system clock

• Ultrasafe reset: same reset strategy including power-on reset, power-down reset,

brownout reset and programmable voltage detector.

Features

ST ultra-low-power continuum also lies in feature compatibility:

• More than 10 packages with pin count from 20 to 144 pins and size down to 3 x 3 mm

• Memory density ranging from 4 to 384 Kbytes
