2.0 V to 5.5 V (ZTAT

TM)

Cautions about operation!

• Electrical properties presented on the data sheet for the mask ROM and ZTATTM versions will surely

and sufficiently satisfy the standard values. However, real capabilities, operation margin, noise margin,

and other properties may vary depending on differences of manufacturing processes, internal wiring

patterns, etc. Therefore, it is requested for users to carry out an evaluation test for each product on an

actual system under the same conditions to see its operation.

• After power supply has been connected, the values for the memory register, data and stack areas will be

undefined. Initialize prior to use.
