Data Sheet

PT7C4302

Real-time Clock Module (3-wire Interface)

•

RAM Burst Mode

The RAM command byte specifies burst mode operation. In this mode, the 31 RAM registers can be consecutively read or written

starting with bit 0 of address 0.

Note: PT7C4302 use 94H, 96H as test mode address. Customer should not use the address.
