Description
The ultralow power STM32L15xxx 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 128 Kbytes and RAM up to 16 Kbytes), and an extensive range of
enhanced I/Os and peripherals connected to two APB buses. All devices offer a 12-bit ADC,
2 DACs and 2 ultralow power comparators, six general-purpose 16-bit timers and two basic
timers, which can be used as time bases. Moreover, the STM32L15xxx devices contain
standard and advanced communication interfaces: up to two I
and a USB. 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 STM32L15xxx 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.
