Custom Configuration Request Procedure

The CY229x are EPROM-programmable devices which may be configured in the factory or in the field by a Cypress Field

Application Engineer (FAE). The output frequencies requested will be matched as closely as the internal PLL divider and multi-

plier options allow. All custom requests must be submmitted to your local Cypress FAE or sales representative. There are two

methods to use to request custom configurations:

1. Use CyClocks software. This software automatically calculates the output frequencies that can be generated by the CY229x

devices and provides a print-out of final pinout which can be submitted (in electronic or print format) to your local FAE or sales

representative. The CyClocks software is available free-of-charge from the Cypress website (http://www.cypress.com) or from

your local sales representative.

2. Use the custom configuration form attached. All areas must be filled in with the exception of shaded cells and the form

submitted to the appropriate Cypress FAE or sales representative.

If requesting samples through the factory:

Once the custom request has been processed you will receive a part number with a 3-digit extension (e.g., CY2292SC-128)

specific to the frequencies and pinout of your device. This will be the part number used for samples requests and production

orders.
