ご担当者様

お世話になっております。

現在コントローラ(FPGA)の省ピン化を目的として、以下型番をA0~A11のアドレスのみ使用、BYTE MODE(Byte#=LOW)で使用を検討しております。

使用する容量に問題がない場合、A12~A20とDQ15(A-1)は直接GND接続で問題なく動作しますでしょうか?(プルダウン接続の方が良いでしょうか?)

また、DQ8-DQ14は未接続(NC)で問題ないでしょうか?

Part# S29GL032N90TFI030

以上、宜しくお願い致します。

Hello,

You can pull down the unused address lines (A12 to A20 and A-1 (DQ15) to ground and leave the unused data pins (DQ8 to DQ14) not connected.

Thanks and Regards
