BAT32G127 series uses the high-performance ARM Cortex-M0®+ 32bit RISC core, which can operate 32MHz, 128KB Flash Memory ,8KB SRAM. This product integrates I2C, SPI and UART standard interfaces, and integrates 12bit A/D converter, 8bit DAC, temperature sensor, comparator and operational amplifier. At the same time, it also has excellent low-power performance, supports two low-power modes of sleep and deep sleep, and is flexible in design. Its operating power consumption is 35uA/ MHz@32MHz In deep sleep mode, the power consumption is only 0.7uA, which is suitable for battery-powered low-power devices.> ARM Cortex M0+ core > Up to 32MHz @1.8V-5.5V > 35uA/MHz @32MHz > Operating voltage: 1.8V-5.5V > Operating temperature: -40℃-105℃ > 128KB Flash > 8KB SRAM > 2.5KB data flash > Up to 60 GPIOs > Hardware multiplier module > 8 16 Bit timers > 1 interval timer of 15 Bit (low power consumption timer) > 1 WDT > 1 RTC Timer > Enhanced DMA controller > Linkage controller > LCD Controler,support 4COM*42SEG/6COM*40SEG/8COM*38SEG > A/D conversion-up to 26 channels of high-precision 12Bit ADC, 0.71Msps > D /A conversion-8Bit accuracy, support 1 channels > 1 channels OPA. > 2 channel comparator, input source and reference voltage optional > 1 I2C standard interface, 3-6 simple I2C interfaces > 1 SPI standard interface,support 8 bit and 16 bit > 3 UART interfaces, support LIN-Bus > Support ultra-low power consumption working mode – sleep mode/deep sleep mode > 0.7uA @deep sleep mode > 0.9uA @deep sleep mode +32.768kHz +RTC > Comply with relevant standards of IEC/UL 60730 > abnormal storage space access error, hardware CRC calibration Inspection, special SFR protection to prevent misoperation > 128-bit unique ID number > Package: LQFP64/LQFP48/QFN40/LQFP32
