The latest in the STM32U0 series from STMicroelectronics, the STM32U083 line, is an energy-saving and cost-effective microcontroller which consumes up to 50% less power than previous generations of MCUs.
ST has achieved this breakthrough in power efficiency in the STM32U083 MCU through a combination of state-of-the-art design techniques and an advanced manufacturing process. These include extremely low static power consumption in standby mode, and superior wake-up performance, enabling the MCU to spend more time in power-saving sleep modes to minimize average energy demand.
The STM32U083 line is based on an Arm® Cortex®-M0+ 32-bit RISC core operating at a frequency of up to 56 MHz, backed by generous memory capacity: 256 kbytes of Flash memory, and a 40 kbyte SRAM with hardware parity check.
Integration is a strong feature of the STM32U083 line. The MCU includes up to 21 capacitive sensing channels, plus an integrated LCD controller which can drive 8 x 48 or 4 x 52 segment displays via an internal step-up converter. Applications with an LCD, such as meters, thermostats, smart retail labels, access control panels, and factory automation equipment, can take advantage of this to streamline the bill-of-materials (BoM).
The integration continues with the provision of analogue and communications peripherals. The STM32U083 MCU includes a 12-bit ADC, a 12-bit DAC, two embedded rail-to-rail analogue comparators, one operational amplifier, and a low-power real-time clock. The on-board timers include one general-purpose 32-bit timer, one 16-bit PWM timer dedicated to motor control, three general-purpose 16-bit timers, and three 16-bit low-power timers.
Part supported: STM32U083
Kit part number: STM32U083C-DK
The STM32U083C-DK Discovery kit from STMicroelectronics is a complete demonstration and development platform for the STM32U083MCT6 microcontroller. It may be used as a reference design for application development before porting to the final product.
The full range of hardware features on the board helps the designer to evaluate all the MCU’s peripherals including the USB 2.0 interface, segment LCD controller, capacitive touch-sensing channels, and temperature sensor.
ARDUINO Uno V3, mikroBUS™ and extension connectors provide for easy connection to extension shields or application-specific daughterboards.
The STM32U083C-DK Discovery kit does not require any separate probe as it has an integrated STLINK-V2EC debugger/programmer. The kit is operated by plugging it into a PC through a standard USB Type-A or USB Type-C®-to-USB Type-C cable.
