Temperature sensor
Temperature sensor consists of built-in 10-bit R-2R DAC, diode and own reference voltage former. When requested, controller performs conversion of diode voltage level, which depends on temperature linearly. After conversion is done it sets “ready” flag to “1” and outputs 10-bit code. Die temperature is calculated with the following expression: Temp = (code-407)*0.625.
The conversion time is 640 us.
With small size, usability and low current consumption, this device is ideal for use in controlling of the die temperature.
The block is fabricated on SMIC CMOS 0.18 um technology.
