NONVOLATILE MEMORY CHARACTERISTICS

= +2.85V to +3.9V, unless otherwise noted.)

Note 1:

All voltages are referenced to ground. Current into the IC is positive, and current out of the IC is negative.

Note 2: Inputs are at supply rail. Outputs are not loaded.

Note 3: This parameter is guaranteed by design.

Note 4: Full-scale is user programmable.

Note 5: A temperature conversion is completed and the DAC values are recalled from the LUTs and V

has been measured to

be above the VCC LO alarm, if the VCC LO alarm is enabled.

Note 6: This specification is the time it takes from RSSI1_ and RSSI2_ voltage falling below the LLOS_ trip threshold to LOSOUT

asserted high.

Note 7: This specification is the time it takes from RSSI1_ and RSSI2_ voltage rising above the HLOS_ trip threshold to LOSOUT

asserted high.

Note 8: I

C interface timing shown is for fast-mode (400kHz) operation. This device is also backward compatible with I

C stan-

dard mode.

Note 9: C

—Total capacitance of one bus line in pF.

Note 10: EEPROM write begins after a STOP condition occurs.
