The SY64912 is a high-accuracy temperature sensor featuring a I²C/I3C-compliant digital interface. The SY64912 is designed for low-power, high-accuracy thermal monitoring applications and is available in a compact 6-ball DSBGA package.

The SY64912 operates with a core power supply of 1.8V and an I/O power supply of 1.8V. It features a low typical average quiescent current of 6μA during each 125ms conversion.

The SY64912 offers a typical accuracy of ±0.25°C across the full temperature range of 0 °C to +70 °C. It integrates an on-chip 11-bit analog-to-digital converter (ADC) designed to operate with a 1.8V core power supply and a wide I/O power supply from as low as 0.95V to as high as 1.98V. The SY64912 also supports advanced features such as in-band interrupts, parity checks, and packet error checks.
