SD8000W

· This chip is a SoC product with a 20-bit ADC, with 16k Bytes OTP, supports self-programming under low voltage (2.4V ~ 3.6V), and can be used instead of EEPROM. Only 5 capacitors are required in the periphery, and the device is very few. The typical working current is only 1.1mA (excluding the power consumption of the sensor), which is very suitable for battery-powered low-power applications such as infrared temperature measurement and body scales.

8-bit RISC ultra-low-power MCU provides three working modes: normal working mode, standby mode, and sleep mode. Let users get the best choice in terms of productivity and energy consumption.

· 20SEG × 4COM LCD driver circuit, ultra-low power consumption and large driving capacity design.

· Flexible battery voltage detection function. · Provide bare chip and various package forms.
