WARNING:
Under no circumstances are negative undershoots, of any amplitude, allowed when device is in write protection.
Note 2:
Limits at -40°C are guaranteed by design and not production tested.
Note 3:
All voltages are referenced to ground.
Note 4:
OE, CE, WE, EXT, and A3–A0.
Note 5:
DQ7–DQ0, SQW, and IRQ, when the outputs are high impedance.
Note 6:
Outputs open.
Note 7:
Specified with parallel bus inactive.
Note 8:
Measured with a 32,768kHz crystal attached to the X1 and X2 pins.
Note 9:
The parameter tOSF is the period of time that the oscillator must be stopped for the OSF flag to be set over the voltage
range of 0V
≤ VCC ≤ VCC(MAX) and 1.3V ≤ VBAT ≤ 3.7V.
Note 10: This delay applies only if the oscillator is enabled and running. If the ENOSC bit is 0, tREC is disabled, and the device is
immediately accessible. If CE and OE are low on power-up, the DQ outputs are active. Valid data out is not available until
after tREC.
