DESCRIPTION

Figure 1. Logic Diagram

The MK41T56 TIMEKEEPER^®is a low power 512

bit static CMOS RAM organized as 64 words by 8

bits. Abuilt-in 32.768 kHzoscillator(external crystal

controlled) and the first 8 bytes ofthe RAMare used

for the clock/calendar function and are configured

in binary coded decimal (BCD) format. Addresses

and data are transferred serially via a two-line

bi-directional bus. The built-in address register is

incremented automatically after each write or read

data byte. The MK41T56 clock has a built-in power

sense circuit which detects power failures and

automatically switches to the battery supply during

power failures. The energy needed to sustain the

RAM and clock operations can be supplied from a

small lithium button cell.
