Product Description

The ultra-low-power STM32L151xC and STM32L152xC devices incorporate the connectivity power of the universal serial bus (USB) with the high-performance ARM® Cortex®-M3 32-bit RISC core operating at a frequency of 32 MHz (33.3 DMIPS), a memory protection unit (MPU), high-speed embedded memories (Flash memory up to 256 Kbytes and RAM up to 32 Kbytes) and an extensive range of enhanced I/Os and peripherals connected to two APB buses.
The STM32L151xC and STM32L152xC devices offer two operational amplifiers, one 12-bit ADC, two DACs, two ultra-low-power comparators, one general-purpose 32-bit timer, six general-purpose 16-bit timers and two basic timers, which can be used as time bases.
Moreover, the STM32L151xC and STM32L152xC devices contain standard and advanced communication interfaces: up to two I2Cs, three SPIs, two I2S, three USARTs and an USB. The STM32L151xC and STM32L152xC devices offer up to 23 capacitive sensing channels to simply add a touch sensing functionality to any application.
They also include a real-time clock and a set of backup registers that remain powered in Standby mode.
Finally, the integrated LCD controller (except STM32L151xC devices) has a built-in LCD voltage generator that allows to drive up to 8 multiplexed LCDs with the contrast independent of the supply voltage.
The ultra-low-power STM32L151xC and STM32L152xC devices operate from a 1.8 to 3.6 V power supply (down to 1.65 V at power down) with BOR and from a 1.65 to 3.6 V power supply without BOR option. They are available in the -40 to +85 °C and -40 to +105 °C temperature ranges. A comprehensive set of power-saving modes allows the design of low-power applications.
