Overview
The CY2081WAF is a standard CY2081 EPROM Programma-
ble clock in die form. The die is intended to be used as a clock
generator integrated with a crystal in a single package. This
integration can dramatically lower the WIP and Lead Time for
Oscillator manufacturing.
All Performance Specifications are based on a CY2081 in a
16-pin SOIC package per Cypress Specification. When the
CY2081WAF is placed in packages as commonly used in the
oscillator market performance will usually meet or exceed the
specifications given in this datasheet. However, Cypress can-
not guarantee performance in these packages. Each company
that uses Cypress die should test and characterize the perfor-
mance of their final product.
