Hi
We received a delivery of CY15B102QSN-108SXI expecting the top marking Line 1 : CY152B3
What we got is the marking CY151B3
Is this also a valid marking for above mentioned device? Are there more valid markings?
Thanks in advance

Is there a layout guide for CY14B101NA-ZS45XIT?
Im seriously looking equivalent for for STK12C68-5L35M
Hello,
I am having trouble getting read responses from a 4Mb fram. I have tried utilizing two different TI launchpads (C2000/Tiva) to communicate with the device. I have been running the clk speed in the 1Mhz to 2Mhz range. Also, I am utilizing a GPIO pin as a chip select as the spi CS peripheral de-asserts after each byte is transmitted. Pseudo code is as follows in my testing program:
set "CS" line high.
setup spi periph for Mode 0
// software reset.
write(0x66)
write(0x99)
delay for 300us
write(0x06)
write(0x02, 0x01, 0x12, 0x34, 0xaa, 0x55)
read(0x03, 0x01, 0x12, 0x34, 0x00, 0x00)
end program.
The parenthesis open indicates CS going low, and parenthesis closed indicates CS going high. In the program, my receive bytes are 0xFF, 0xFF. In other testing programs, I have tried writing to the status/config registers and I am getting 0xFF bytes as well.
I am including scope shots from the TI C2000 based board. Are there any steps that I am missing in getting the device to function? Thanks for the help.

Hello,
I'm inquiring whether there exists a dedicated Linux device driver or a compatible one for facilitating communication with the FM31256-G chip via the I2C protocol.
Your assistance on this matter would be greatly appreciated.
Thank you in advance.

Hi team ,
For part series CY15B004Q-SXE* under operating range ambient temperature range is define can we use it as a
recomended operating temperature range . under the thermal data junction-case thermal resistance and junction-ambient thermal resistance is present we also need the value of junction-board thermal resistance.
looking for your soonest response.

Regarding CY14B101LA-BA45XIT, is there any command to read device ID or UID like flash memory?
The data sheet doesn't mention it, so can you tell me?
