Description
The ultralow power STM32L15xxD incorporates the connectivity power of the universal
serial bus (USB) with the high-performance ARM Cortex
a 32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories
(Flash memory up to 384 Kbytes and RAM up to 48 Kbytes), a flexible static memory
controller (FSMC) interface (for devices with packages of 100 pins and more) and an
extensive range of enhanced I/Os and peripherals connected to two APB buses.
All devices offer three 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 STM32L15xxD devices contain standard and advanced communication
interfaces: up to two I
USB. 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 ultralow power STM32L15xxD 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.
