Note 1

Absolute Maximum Ratings are those values beyond which damage to the device may occur

Note 2

Unless otherwise specified all voltages are referenced to ground

Note 3

For FOSC e 4194304 or 49152 MHz VBB minimum e 28V In battery backed mode VBB s VCC b04V

Single Supply Mode Data retention voltage is 22V min

In single Supply Mode (Power connected to VCC pin) 45V s VCC s 55V

Note 4

This parameter (VIH) is not tested on all pins at the same time

Note 5

This specification tests ICC with all power fail circuitry disabled by setting D7 of Interrupt Control Register 1 to 0

Note 6

This specification tests ICC with all power fail circuitry enabled by setting D7 of Interrupt Control Register 1 to 1

Note 7

This specification is tested with both the timers and OSC IN driven by a signal generator Contents of the Test Register e 00(H) the MFO pin is not

configured as buffered oscillator out and MFO T1 INTR are configured as open drain

Note 8

This specification is tested with both the timers off and only OSC IN is driven by a signal generator Contents of the Test Register e 00(H) and the MFO

pin is not configured as buffered oscillator out
