User of MR27V3266D is recommended to study the relation between "Address displayed on programmer" and
"Address(STO="L")" ignoring "Device Address:x16, STO="H"".
Order of data on Synchronous Read operation(STO="L") is checked on this table.
"Device Address:x16, STO="H"" will be utilized to design socket adapter on programmer or to check boards
designed to mount blank OTP and program OTP on board.
OKI will supply socket adapter to program MR27V3266D as conventional x16 standard OTP. The users and the
venders of programmer who use the socket adapter can ignore "Device Address:x16, STO="H"".
Note
1. A0 in programmer distinguishes upper word(x16) or lower word(x16) of Double word(x32).
On word(x16) organization the address of device corresponds to the address of programmer.
On double word(x32) organization the address numeral code of device is half of that in programmer, and
output on DQ0-DQ15 is lower word(A0="0") and output on DQ16-DQ31 is upper word(A0="1").
2. CA1 is MSB of burst read on condition of /WORD="L" and BL=4
3. CA2 is MSB of burst read on condition of /WORD="L" and BL=8
4. CA1 is MSB of burst read on condition of /WORD="H" and BL=4
5. CA2 is MSB of burst read on condition of /WORD="H" and BL=8
