Description
The medium density plus ultralow power STM32L15xxC incorporates the connectivity power
of the universal serial bus (USB) with the high-performance ARM Cortex
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.
All medium density plus devices offer two operational amplifiers, one 12-bit ADC, two DACs,
two ultralow 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 I
Up to 36 channels are available for capacitive sensing directly driven through GPIOs and
general purpose timers.
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 ultralow 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. A comprehensive
set of power-saving modes allows the design of low-power applications.
