New low-cost, low-power 32-bit MCU streamlines BoM in display-based applications
The STM32U083 line microcontrollers from STMicroelectronics integrate multiple functions alongside an Arm® Cortex®-M0+ 32-bit RISC core, including an LCD controller, generous memory capacity, and a broad range of analog peripherals.
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.
