Hi,

I have two questions, so please teach me.

1. Please let me know the Max value of Total Write Buffer Program Time.
   (Datasheet P70, 16 Erase And Programming Performance)

2. Please let me know the value of Symbol R and N.
   (Datasheet P72, 18.1 TS048—48-Pin Standard Thin Small Outline Package (TSOP))

Hi Kumada san,

The Max value of Total Write Buffer Program Time is not part of the datasheet because instead of relying on a fixed timeout for programming, we like to advise customers to use DQ5 polling which will use internal pulse count limits for better accuracy. Please see below snip from datasheet -

Hi Kumada san,

Thank you for contacting Cypress Semiconductor.

Q1. I am discussing your query internally and shall get back to you on this shortly.

Q2. The value of symbol R is provided for TSO56 on page 73. Same value can be used for TSO48 as well.

       The value of N will be 48.

Regards,

Apurva
