The STM32G081xB mainstream microcontrollers are based on high-performance Arm® Cortex®-M0+ 32-bit RISC core operating at up to 64 MHz frequency. Offering a high level of integration, they are suitable for a wide range of applications in consumer, industrial and appliance domains and ready for the Internet of Things (IoT) solutions.The devices incorporate a memory protection unit (MPU), high-speed embedded memories (up to 128 Kbytes of Flash program memory and 36 Kbytes of SRAM), DMA and an extensive range of system functions, enhanced I/Os and peripherals.The devices offer standard communication interfaces (two I2Cs, two SPIs / one I2S, one HDMI CEC and four USARTs), one 12-bit ADC (2.5 MSps) with up to 19 channels, one 12-bit DAC with two channels, two fast comparators, an internal voltage reference buffer, a low-power RTC, an advanced control PWM timer running at up to double the CPU frequency, five general-purpose 16-bit timers with one running at up to double the CPU frequency, a 32-bit general-purpose timer, two basic and two low-power 16-bit timers, two watchdog timers, and a SysTick timer. The STM32G081xB devices provide a fully integrated USB Type-C Power Delivery controller.The devices embed AES hardware accelerator and true random number generator (RNG).The devices operate within ambient temperatures from -40 to 125°C. They can operate with supply voltages from 1.7 V to 3.6 V. Optimized dynamic consumption combined with a comprehensive set of power-saving modes, low-power timers and low-power UART, allows the design of low-power applications.VBAT direct battery input allows keeping RTC and backup registers powered.The devices come in packages with 28 to 64 pins.Key FeaturesCore: Arm® 32-bit Cortex®-M0+ CPU, frequency up to 64 MHz-40°C to 85°C/125°C operating temperatureMemory128 Kbytes of Flash memory36 Kbytes of SRAM (32 Kbytes with HW parity check)Clock management4 to 48 MHz crystal oscillator32 kHz crystal oscillator with calibrationInternal 16 MHz RC with PLL option (±1 %)Internal 32 kHz RC oscillator (±5 %)Up to 60 fast I/OsAll mappable on external interrupt vectorsMultiple 5 V-tolerant I/Os7-channel DMA controller with flexible mapping12-bit, 0.4 µs ADC (up to 16 ext. channels)Up to 16-bit with hardware oversamplingConversion range: 0 to 3.6VTwo 12-bit DACs, low-power sample-and-holdTwo fast low-power analog comparators, with programmable input and output, rail-to-rail14 timers (two 128 MHz capable): 16-bit for advanced motor controlOne 32-bit and five 16-bit general-purpose, two basic 16-bit, two low-power 16-bit, two watchdogs, SysTick timerCalendar RTC with alarm and periodic wakeup from Stop/Standby/ShutdownCommunication interfacesTwo I2C-bus interfaces supporting Fast-mode Plus (1 Mbit/s) with extra current sink, one supporting SMBus/PMBus and wakeup from Stop modeFour USARTs with master/slave synchronous SPI; two supporting ISO7816 interface, LIN, IrDA capability, auto baud rate detection and wakeup featureLow-power UARTTwo SPIs (32 Mbit/s) with 4- to 16-bit programmable bitframe, one multiplexed with I2S interfaceHDMI CEC interface, wakeup on header receptionUSB Type-C™ Power Delivery controllerTrue random number generator (RNG)AES: 128/256-bit key encryption hardware acceleratorDevelopment support: serial wire debug (SWD)96-bit unique IDAll packages ECOPACK®2 compliant
