STM32L151x6/8/B STM32L152x6/8/B
The ultra-low-power STM32L151x6/8/B and STM32L152x6/8/B devices incorporate the
connectivity power of the universal serial bus (USB) with the high-performance ARM®
Cortex®-M3 32-bit RISC core operating at 32 MHz frequency (33.3 DMIPS), 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 the devices offer a 12-bit ADC, 2 DACs and 2 ultra-low-power comparators, six general-
purpose 16-bit timers and two basic timers, which can be used as time bases.
Moreover, the STM32L151x6/8/B and STM32L152x6/8/B devices contain standard and
advanced communication interfaces: up to two I2Cs and SPIs, three USARTs and a USB.
The STM32L151x6/8/B and STM32L152x6/8/B devices offer up to 20 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 (except STM32L151x6/8/B devices) has a built-in LCD
voltage generator that allows to drive up to 8 multiplexed LCDs with contrast independent of
the supply voltage.
The ultra-low-power STM32L151x6/8/B and STM32L152x6/8/B 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. 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.
