Hello,

is it possible to extract the JEDEC file from a CY22381 programmed with the CY3675-CLKMAKER1 programmer?

Thanks

According to the following tables is the CY3675 programmer + CY3675-SOIC8B socket, but the CY3675-SOIC8B does not exist

Have CY294xxLXIxxxT factory-configured part number to replace CY2X014LXC100T?

If not, could you provide CY2X014LXC100T factory-configured content for make CY2942xFLXI sample?

Or provide CY2942x ClockWirzard project file for field-programming?

Hello

Q)

If CLKA3(14pin)  is not used, please tell me pin proccessing of unused pin(CLKA3) as an "EMI" countrmeasure? Is CLKA3(14pin) open? Or is it necessary to add the capacitor? (Other port condition): CLKB1, CLKB2, CLKB3, and CLKB4 are not driven.

In addition, they found the following application note ,it is described that If EMI is a problem, mount a 5pF to 10pF capacitor during testing on page 6.

1. Hello.

My project uses the PLL Cypress CY27410FLTXI chip. I want to program it through the I2C interface using the I2C master implemented in FPGA. The configuration data is in the FPGA memory. In order to program it, I need to write 384 bytes of configuration data via I2C (128 bytes for the CM area and 256 for Profile_0 area). The I2C interface only addresses 256 bytes. How do I program CY27410FLTXI?

Hello,

Please tell me about CY2DL1510AZC's  junction temperature: Tj and package thermal resistance: Θjc.

Best Regards,

Though CY2907 is obsolete, I a need 5Volt PLL for under a $1 so the CY2907FX8 seems perfect.

One (obscure) website shows old new 59392 pcs in stock $0.953 for 100 units.

It will use a crystal input of 14-17MHz range.

I need two settings:
4x pll  then divided by 9 

4x pll  then divided by 7

Both with X1 crystal ref output as 2nd clock.

Can it do that and does cypress support programming of this part?

Hi.

We bought CY22801KFXC chips from DIgi-key

But the function is not the same as what we want.

We want the chip to behave as I2C slave, And from the data sheet we got to now about the multi-functional pins [3,5,7] and

that pins are should be in the mode of "G" , how to configure the modes .

Or we have to buy the already configured IC with the mode of 'G' and where we have to buy.

Using part number CY7B992-7JI in an application with datasheet environment variables of F=80, C=50 and N=8, occasionally supply current values are observed in excess of the estimated 272mA max . As such, is 300mA a reasonable ceiling for supply current across a large sample of parts or is there another more aggressive  limit that good parts would be sure not to exceed across the full temperature range for this device?
