描述
The STM32U073x8/B/C devices are ultra-low-power microcontrollers based on the high-performance Arm® Cortex®-M0+ 32-bit RISC core operating at a frequency of up to 56 MHz.
The STM32U073x8/B/C devices embed high-speed memories (up to 256-Kbyte flash memory and 40-Kbyte SRAM with hardware parity check), and an extensive range of enhanced I/Os and peripherals connected to APB and AHB buses, and a 32-bit multi-AHB bus matrix.
They also embed protection mechanisms for embedded flash memory and SRAM, such as readout protection and write protection.
The STM32U073x8/B/C devices offer a 12-bit ADC, a 12-bit DAC, two embedded rail-to-rail analog comparators, one operational amplifier, a low-power RTC, 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
The devices also embed up to 21 capacitive sensing channels, plus an integrated LCD controller that enables to drive 8x48 or 4x52 segments with internal step-up converter.
They also feature standard and advanced communication interfaces, namely four I2Cs, three SPIs, four USARTs and three low-power UARTs, plus one crystal-less USB full-speed device.
The STM32U073x8/B/C operate in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges from a 1.71 to 3.6 V VDD power supply using an internal LDO regulator. A comprehensive set of power-saving modes makes possible the design of low-power applications.
Independent power supplies are supported: analog independent supply input for ADC, DAC, OPAMP and comparator, as well as VBAT input allowing the backup of the RTC and backup registers.
The STM32U073x8/B/C offer eight packages from 32 to 81 pins.
