DESCRIPTION
The M48Z09,19 ZEROPOWER
RAM is an 8K x 8
non-volatile static RAM which is pin and function
compatible with the MK48Z09,19.
A special 28 pin 600mil DIP CAPHAT
package
houses the M48Z09,19 silicon with a long life lith-
ium button cell to form a highly integrated battery
backed-up memory solution.
