DDC2256A: Temperature Sensor

Anthony krecic

Part Number: DDC2256A

After setting DDC2256A's ENABLE_TEMP_SENSOR (0x25[7]) to 1, datasheet indicates data header becomes 24bit + 16bits corresponding to temperature sensor + 8 zeroes. Is this true for both 24bit and 20bit data word modes? Or, when in 20bit data mode, is the header 20bit + 16bit corresponding to temperature sensor + 4 zeroes?

Thank you

Hi,

Thanks for the patience.

When the device is in 20-bit data mode and the ENABLE_TEMP_SENSOR is set to 1, the 40-bit header data format is shown below .

40-bit HEADER data = [20-bit header] + [16-bit corresponding to temperature sensor] + [4 zeros]

Thanks
