Programming Description
Field Programmable CY25100
The CY25100 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 CY25100 is Flash
technology based, which allows it to be reprogrammed up to 100
times. This allows fast and easy design changes and product
updates, and eliminates issues with old and out of date inventory.
Samples and small prototype quantities can be programmed on
the CY3672 programmer with the CY3690 (TSSOP package) or
CY3691 (SOIC package) socket adapter.

Crystal input or reference clock input.
User has the option of choosing either PD# or OE function.
Power Down pin: Active LOW. If PD# = 0, PLL and crystal oscillator circuit are powered
down, and outputs are weakly pulled low.
Output Enable pin: Active HIGH. If OE = 1, SSCLK and REFCLK are enabled.
Power supply ground.
Buffered reference output.
Spread spectrum clock output.
Spread spectrum control: Active LOW. 0 = spread on. 1 = spread off.

CyberClocks™ Online Software
CyberClocks™ Online Software is a web based software appli-
cation that allows the user to custom-configure the CY25100. All
of the parameters in
software. CyberClocks Online outputs an industry-standard
JEDEC file which is used for programming the CY25100. Cyber-
Clocks Online is available at

CY3672 Programmer and CY3690/CY3691 Socket
Adapters
The Cypress CY3672 programmer and the CY3690 or CY3691
socket adapter may be used to program field programmable
versions of the CY25100. The CY3690 enables users to program
the CY25100ZXCF and CY25100ZXIF (TSSOP). CY3691
