STM32L082CZY6TR Description
The high-performance Arm Cortex-M0+ 32-bit RISC core operates at a 32 MHz frequency in the ultra-low-power STM32L082CZY6TR microcontroller. It also features a memory protection unit (MPU), high-speed embedded memories (up to 192 Kbytes of Flash program memory, 6 Kbytes of data EEPROM, and 20 Kbytes of RAM), as well as a wide variety of enhanced I/Os and peripherals.
High power efficiency for a variety of performances is offered by the STM32L082CZY6TR device. This is made possible by a broad selection of internal and external clock sources, a built-in voltage adaption, and numerous low-power modes.
The STM32L082CZY6TR device includes a number of analog features, including a 12-bit ADC with hardware oversampling, two DACs, two ultra-low-power comparators, AES, and several timers, including one low-power timer (LPTIM), four general-purpose 16-bit timers, two basic timers, an RTC, and a SysTick that can be used as a time base. Additionally, they have two watchdogs: one with independent clock and window functionality and the other with a window watchdog based on a bus clock.
The STM32L082CZY6TR device also incorporates both conventional and cutting-edge communication interfaces, including up to three I2Cs, two SPIs, one I2S, four USARTs, and a low-power UART (LPUART), and a crystal-free USB. The gadgets allow you to easily add touch sensing functionality to any application thanks to their up to 19 capacitive sensing channels.
A real-time clock and several backup registers that are powered on even when the device is in standby mode are also included in the STM32L082CZY6TR.
The ultra-low-power STM32L082CZY6TR gadget runs on a 1.8 to 3.6 V power supply with BOR and a 1.65 to 3.6 V power supply without BOR option (down to 1.65 V at power down). They are offered in the temperature range of -40 to +125 °C. The development of low-power applications is made possible by a wide range of power-saving modes.
