The medium density plus ultra-low-power STM32L15xxC incorporates the connectivity 
power of the universal serial bus (USB) with the high-performance ARM Cortex-M3 32-bit 
RISC core operating at a 32 MHz frequency, 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 STM32L15xxC medium density plus 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 medium density plus STM32L15xxC devices contain standard and advanced 
communication interfaces: up to two I2Cs, three SPIs, two I2S, three USARTs and a USB. 
The STM32L15xxC devices offer up to 23 capacitive sensing channels to simply add 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 has a built-in LCD voltage generator that allows you to 
drive up to 8 multiplexed LCDs with contrast independent of the supply voltage.

The medium density plus ultra-low-power STM32L15xxC operates 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. It is available in the -40 to +85 °C temperature range, extended 
to 105°C in low power dissipation state. A comprehensive set of power-saving modes allows 
the design of low-power applications.
