11 / 121 page STM32L151x6/8/B, STM32L152x6/8/B Description Doc ID 17659 Rev 8 11/121 2.2 Ultra-low-power device continuum The ultra-low-power STM32L151xx and STM32L152xx 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 ultralow leakage process. Note: 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. 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 and STM32L15xxx 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 STM32L15xx 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 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 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 |
