The STM32U083xC devices are ultra-low-power microcontrollers based on the high-performance Arm Cortex-M0+ 32-bit RISC core, operating at frequencies up to 56 MHz. The STM32U083xC devices embed high-speed memories (256 KB Flash and 40 KB SRAM with hardware parity check), as well as a wide range of enhanced I/Os and peripherals connected to the APB and AHB buses, and a 32-bit multi-AHB bus matrix.
They also embed protection mechanisms for the embedded Flash and SRAM, such as read-out protection and write protection. The STM32U083xC devices offer a 12-bit ADC, a 12-bit DAC, 2 embedded rail-to-rail analog comparators, an operational amplifier, a low-power RTC, a general-purpose 32-bit timer, a 16-bit PWM timer dedicated to motor control, 3 general-purpose 16-bit timers and 3 16-bit low-power timers. These devices also embed up to 21 capacitive sensing channels, plus an integrated LCD controller capable of driving 8x48 or 4x52 segments through an internal boost converter. They also feature standard and advanced communication interfaces, namely 4 I2C, 3 SPI, 4 USART and 3 low-power UART, as well as a crystal-less USB full-speed device.
In addition, the STM32U083xC devices embed an AES hardware accelerator. The STM32U083xC operates over the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges and uses an internal LDO regulator with a voltage range of 1.71 to 3.6 V VDD. A full set of power-saving modes enables the design of low-power applications.
