Description
The high density ultralow power STM32L162xD incorporates the connectivity power of the
universal serial bus (USB) with the high-performance ARM Cortex
operating at 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 high density devices offer three operational amplifiers, one 12-bit ADC, two DACs, two
ultralow power comparators, AES, 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 high density STM32L162xD devices contain standard and advanced
communication interfaces: up to two I
two UARTs and a 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 high density ultralow power STM32L162xD 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.
