Hi
I want to interface N25Q128A11ESF40F with K60 I am going to use SPI 2 of K60.
Could you please tell me how the connections are to be done.
I am sending the datasheet of N25Q128A11ESF40F along with this mail.

Solved! Go to Solution.
Hi, Hari
For SPI module connection, you can connect as below.
N25Q128AESF40F K60
DQ1 SPI1_SIN
DQ0 SPI1_SOUT
C SPI1_SCK
S SPI1_PCS
HOLD signal should be pull-up for normal communication.
W signal should be pull-up for non-write protection. If you want to control this signal, you can connect to one GPIO.
Hope my reply can help you.

Hi Hari,
N25Q128A11ESF40F support SPI interface just like AT26DF081A which is a flash memory chip in TWR-EME board. I suggest that you can reference its schematic and I will send the schematic along with the email.
But one thing should attract your attention, the supply voltage of N25Q128A11ESF40F is between 1.7 and 2.0 V, however the range of K60 is 1.7 to 3.6V.
Their supply voltage should be guaranteed at same level. Wish you succeed.

Hi Ping Zhou,
Thank you very much .If you don't mind please send me the schematic as you mentioned in your previous mail.(AT26DF081A which is a flash memory chip in TWR-EME board)

Hi Ping Zhou,
Thank you very much.I am going to use TXB0304RUT { 4-BIT BIDIRECTIONAL VOLTAGE-LEVEL TRANSLATOR WITH AUTOMATIC DIRECTION
SENSING} from TI.
If possible please suggest the how connections are to be done.This IC has only for pins but I have 4 signals here.Can I use voltage divider for W signal.
K60 | TXB0304(3V3) |
SPI1_SIN | A1 |
SPI1_SOUT | A2 |
SPI1_SCK | A3 |
SPI1_PCS | A4 |
W | Voltage divider |
Given above is the connections which I planned.If have any alternative or Suggestions please let me know.
Thanks&Regards
