LS1D100

Loongson 1D100 is a dedicated MCU chip for ultrasonic water meters, heat meters, and gas meters, integrating CPU, FLASH, Time-to-Digital Converter (TDC), Ultrasonic Pulse Generator, Temperature Sensor (THSENS), SPI, I2C, UART, MBUS, Segment LCD Controller, ADC, RTC, Empty Pipe Detection, Wire Break Detection, and other functional modules. Using the QFP80 package, with a quiescent current of less than 10μA, it features high timing measurement accuracy, rich peripheral functions, and low power consumption. Along with a comprehensive programming, simulation, and debugging environment, it significantly simplifies the software and hardware design of the ultrasonic flow measurement system.
