Data retention time is in excess of 10 years with a
50mAh 3V lithium cell. The MK41T56 is supplied in
8 pin Plastic Dual-in-Line and 8 lead Plastic SOIC
packages.
OPERATION
The MK41T56 clock operates as a slave device on
the serial bus. Access is obtained by implementing
a start condition followed by the correct slave ad-
dress (11010000). The 64 bytes contained in the
device can then be accessed sequentially in the
following order:
