Programming Description
Field-Programmable CY25200
The CY25200 is programmed at the package level, that is, in a
programmer socket. The CY25200 is Flash technology based,
so the parts are reprogrammed up to 100 times. This allows for
fast and easy design changes and product updates, and elimi-
nates any issues with old and out of date inventory.
Samples and small prototype quantities are programmed on the
CY3672 programmer with the CY3695 socket adapter.
CyberClocks
™ Online Software
CyberClocks
™ Online Software is a web based software appli-
cation that allows the user to custom configure the CY25200. All
the parameters in given as “Enter Data” are programmed into the
CY25200. CyberClocks Online outputs an industry standard
JEDEC file used for programming the CY25200. CyberClocks
