For V
biased and consumes 80 µA (typical) until the sensor POR resets and acknowledges a shutdown
command. See
Characterized but not production tested. For endurance estimates in a specific application, please consult
the Total Endurance™ Model which can be obtained from Microchip’s web site at www.microchip.com.
The range of voltage applied at A0 pin for Permanent Write Protect is GND to V
and Section 5.3.3 “Write Protection”.
These specifications apply for the Temperature Sensor and EEPROM.
For V
biased and consumes 80 µA (typical) until the sensor POR resets and acknowledges a shutdown com-
