STM32L100C6, STM32L100R8/RB Description
DocID024295 Rev 1 11/102
2.2 Ultralow power device continuum
The ultralow power STM32L100C6 and STM32L100R8/B are fully pin-to-pin and software
compatible. Besides the full compatibility within the family, the devices are part of
STMicroelectronics microcontrollers ultralow power strategy which also includes STM8L1xx
and STM8L0xx devices. The STM8L and STM32L families allow a continuum of
performance, peripherals, system architecture and features.
They are all based on STMicroelectronics ultralow leakage process.
Note: The ultralow 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.
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 ultralow power performance to range from 5 up to 33.3 DMIPs.
2.2.2 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
2.2.3 Common system strategy
To offer flexibility and optimize performance, the STM8L15xx and STM32L1xxxx families
use a common architecture:
• Same power supply range from 1.8 V to 3.6 V
• Architecture optimized to reach ultralow 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.
2.2.4 Features
ST ultralow 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
