Description

2.2

Ultra-low-power device continuum

The ultra-low-power family offers a large choice of cores and features. From proprietary 8-

bit to up to Cortex-M3, including the Cortex-M0+, the STM32Lx series are the best choice to

answer the user needs, in terms of ultra-low-power features. The STM32 ultra-low-power

series are the best fit, for instance, for gas/water meter, keyboard/mouse or fitness and

healthcare, wearable applications. Several built-in features like LCD drivers, dual-bank

memory, Low-power run mode, op-amp, AES 128-bit, DAC, USB crystal-less and many

others will clearly allow to build very cost-optimized applications by reducing BOM.

Note:

STMicroelectronics as a reliable and long-term manufacturer ensures as much as possible

the pin-to-pin compatibility between any STM8Lxxxxx and STM32Lxxxxx devices and

between any of the STM32Lx and STM32Fx series. Thanks to this unprecedented

scalability, the old applications can be upgraded to respond to the latest market features and

efficiency demand.

2.2.1

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.

2.2.2

Shared peripherals

STM8L15xxx, STM32L15xxx and STM32L162xx 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

Operating temperatures

Ambient operating temperature: -40 °C to 85 °C / -40 °C to 105 °C

Junction temperature: –40 to + 110 °C
