- Product Parameters Core Chip: SC7A20H Working Voltage: 1.71V–3.6V DC Measurement Range: ±2G/±4G/±8G/±16G Resolution: 12-Bit Effective Data Output (±0.5mg/LSB @ ±2G) Output Data Rate (ODR): 1.56Hz to 4.27kHz (Configurable, Default 100Hz) Communication Interfaces: I²C (Default Address 0x18/0x19, Supports 100kHz/400kHz Rates) SPI (Supports 4-Wire/3-Wire Mode, Clock Frequency ≤ 10MHz) Power Consumption: Operating Current: 150µA (Continuous Mode @ 100Hz) Sleep Current: 2µA (Low Power Mode @ 1.56Hz) Mechanical Properties: Impact Resistance: 10,000g (Reliable Protection) Operating Temperature: -40°C to +85°C (Industrial Wide Temperature Range) Built-In Features: 32-Level FIFO Buffer, Self-Calibration Module, Temperature Compensation. 🔌 Pin Functions VDD: Power Input Positive Pole (1.71V–3.6V DC). External 100nF Ceramic Capacitor Recommended (Distance ≤ 2mm). GND: Power Ground. Must Be Shared with MCU via Single-Point Grounding to Reduce Ground Loop Interference. SCL: I²C Clock Line (Open-Drain Output). Requires 4.7kΩ Pull-Up Resistor to VDD (Reduce to 2.2kΩ for 400kHz Mode). SDA: I²C Data Line (Open-Drain Output). Pull-Up Resistor Configuration Same as SCL. CS: SPI Chip Select Pin (Active Low). Must Be Pulled to VDD in I²C Mode. INT1/INT2: Programmable Interrupt Outputs (Active Low). Support Free-Fall, Motion Wake-Up, and Other Event Triggers. SDO/SA0: SPI Data Output / I²C Address Selection (GND = Address 0x18, VDD = Address 0x19).
