I think the difference between S29AL016J70TFI010 and S29AL016J70TFI020 is the difference between top boot sector device and bottom boot sector device. Is there any revision required when using S29AL016J70TFI010 when using S29AL016J70TFI020?

hello Everyone,

The footprint for S25HS01GTDPBHM03 component is not available in it's Datasheet. Please Let me know where can i get the footprint of it. Expecting a quick reply.

Thanks in Advance!

Hello

We have been using S29GL064N90TF103 for a while without issue and I have just tested three boards with the newer/faster replacement, Cypress S29GL064S70TF103, and the S29GL-S parts are not reporting the CFI Query string.

With the code below, both devices (the S29GL-N and S29GL-S) properly return these values as expected:

FlashCFI.mfgCode =0001h
FlashCFI.deviceCode[0]=227Eh
FlashCFI.deviceCode[1]=2210h
FlashCFI.deviceCode[3]=2201h

But the boards with the newer S29GL-S parts are returning these incorrect results:

query[0]=0x0001 //Error - Should be 'Q'
query[1]=0x227E //Error - Should be 'R'
query[2]=0x0000 //Error - Should be 'Y'

All 3 failing FLASH devices are marked:

S29GL064S70TF103
749BB481 A
(c) 13   SPANSION

I'm at a loss... Any suggestions?

Thanks!

I need to read the Ready/Busy [RY/BY#] signal with a 3.3V device. Can I pull-up to 3.3V when the IO voltage is 1.8V? Save a level translator if I can without damaging the device.  It is open drain and the core reference is 3.3V but the IO is 1.8.  I don't see this documented in the data sheet.

S70GL02GT is the memory type

I am using the memory verilog model in S29VS-R_VERILOG.zip. When I polling Status[7] after issuing "Buffer to Flash" in Secure Silicon Region, the model always feedback SSR array value instead of Status after programing done (current_state back to "SecSi_ENTRY"). I want to know if this is the expected behavior or something wrong there.

Verilog pieces  (Line# 2434~2460)

SecSi_ENTRY:
begin
if (falling_edge_WRITE)

...
if (oe)  // No status read branch here 
begin
    if (SecAddr == SA_SecSi)
    begin
        READMEM(ReturnAddr(Addr,SecAddr),SecAddr,SS_T);
        Dout_zd = OutputD;
    end
    else
    begin
       READMEM(Addr,SecAddr,Mem_T);
       Dout_zd = OutputD;
    end
end
end

Datasheet Rev L,

In table 8 the size of CFI data and the byte address range are not consistent. Range 00020h~000CEh (Here is also a typo in the table) means the size = 206d - 32d + 1d = 175 but the table scribed 174 which is confusing. 

Also, is the ID/CFI ASO support Continuous & Linear Synchronous Read? The datasheet mentions SSR support both async/sync read but doesn't tell if ID/CFI supports it or not. 

Thank you.

Regards,

Keter

Are the areas that can be locked with a password as follows?

　Security area 2 (256 bytes with an address range of 200 to 2FF)

　Security area 3 (256 bytes with address range of 300 to 3FF)
