STM32L152ZD:Ultra-low-power ARM Cortex-M3 MCU with 384 Kbytes Flash, 32 MHz CPU, LCD, USB, 3xOp-amp.
The ultralow power STM32L15xxD family includes devices in 4 different package types: from 64 pins to 144 pins. Depending on the device chosen, different sets of peripherals are included, the description below gives an overview of the complete range of peripherals proposed in this family.
These features make the ultralow power STM32L15xxD microcontroller family suitable for a wide range of applications:
● Medical and handheld equipment
● Application control and user interface
● PC peripherals, gaming, GPS and sport equipment
● Alarm systems, wired and wireless sensors, Video intercom
● Utility metering
The ultralow power STM32L15xxD incorporates the connectivity power of the universal serial bus (USB) with the high-performance ARM Cortex™-M3 32-bit RISC core 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.
The STM32L15xxD 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 I2Cs, three SPIs, two I2S, one SDIO, three USARTs, 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 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.
