Programming Description

Field-Programmable CY25200

The CY25200 is programmed at the package level, and must be

programmed prior to installation on a circuit board. Field

programmable devices are denoted by an “F” in the ordering

code, and are blank when shipped. The CY25200 is Flash

technology based, which allows it to be reprogrammed up to 100

times. This allows for fast and easy design changes and product

updates, and eliminates issues with old and out of date inventory.

Samples and small prototype quantities are programmed on the

CY3672 programmer with the CY3695 socket adapter.

application that allows the user to custom configure the

CY25200. All the parameters in Table 2 and Table 3 are entered

as variables into the software. CyberClocks Online outputs an

industry standard JEDEC file used for programming the

Factory-Programmed CY25200

Factory programming by Cypress is available for high volume

orders. All requests must be submitted to the local Cypress Field

Application Engineer (FAE) or sales representative. After the

request is processed, you will receive a new part number,

samples, and data sheet with the programmed values. This part

number is used for additional sample requests and production

orders.
