NONVOLATILE MEMORY CHARACTERISTICS
(VCC = +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 VCC 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: I2C interface timing shown is for fast-mode (400kHz) operation. This device is also backward compatible with I2C stan-
dard mode.
Note 9: CB—Total capacitance of one bus line in pF.
Note 10: EEPROM write begins after a STOP condition occurs.
