Hello,

I would like to know the max junction temperature for the above component. The datasheet only has the operating and storage temperature. Thanks!

Hi friends,

can anyone help pls with the CY7C2665KV18-450BZXI

What does the last line mean?

Best regards

Hello, I'm working on a design with CY7C4122KV13.  As per the warnings in the data sheet, the use of TRST# is not optional for this device.  I intent to use JTAG.  In the reset sequence (page 11) step 1 says we have to start out with RST# and TRST# low.  In none of the following steps does it say what you need to do with TRST#, and when.  I'm trying to keep this simple, and not have to have do something like have logic gates with reset as an input to drive TRST.  What exactly do I need to do with it?

The opposite device's Vih (min) is 3.5V and the CY62156's Voh (min) is 2.4V. Therefore, it is not possible to connect directly.

Is it possible to add an external pull-up resistor for connection? According to the data sheet, Ioh is 1mA, so I'm thinking of setting the resistance value to about 2.6kohm.
(5V-2.4V) / 1mA = 2.6k)

Thanks,
Tetsuo

Rochester Electronics has a part number CY7C038V-20AIKJ, does anyone identify the KJ suffix as i have been unable to find a datasheet containing it

According to Document Number: 001-79552 Rev. *O,POD is supported at VDDQ voltages of 1.1 V and 1.2 V nominal,Now customer's main-controller Intel Stratix 10 sx FPGA can just use POD 1.2V signaling,but CY7C4042KV13-933FCXC is a commercial part,in Operating Range we can see it can just use VDDQ=1.1V,if can CY7C4042KV13-933FCXC works with 1.2V VDDQ ?
BTW,If we must change to Industrial part,Now we can't find a registrable P/N,Please help advise, Many Thanks!

Hi,

I'm using a CY14B101PA-SFXI nvSRAM to store and read data with my application (programmed in C) in a microsemi fpga (smartfusion).

Until now, I was using the spi (serial peripheral interface)drivers (direct communication with the nvSRAM) with no problems, using the data protocol provided in the datasheet of the nvSRAM.

Now we want to use a PDMA (Peripheral Direct Memory Access) to make the communication with the nvSRAM, but we are having problems and I can't make a proper communication. Is there any change in the communication protocol?

Example: Right now we are sending folowing instruction to read from direction 0x0000FA

uint_8 send_Buffer[4] = {0x03, 0x00, 0x00, 0xFA}

This instrucction works well with spi drivers, but when we use PDMA drivers we are having problems.

Thanks in advance.

Hi all.

I'd like to know Truth Table of CY7C1051H30-10ZSXI & CY7C1051DV33-10ZSXI.

CY7C1051H30 Truth Table has this condition "L X X H H" in data sheet .      But CY7C1051DV33-10ZSXI does not have this condition in data sheet.

I think that CY7C1051DV33-10ZSXI  also can support this condition of Truth Table.

Could you please tell us whether CY7C1051DV33-10ZSXI can support "L X X H H" of Truth Table ?
