Function
The pin for switching WORD mode and BYTE mode.
High level : WORD mode (4M-word by 16-bit)
Low level : BYTE mode (8M-word by 8-bit)
Address input pins.
A0 to A21 are used differently in the WORD mode and the BYTE mode.
WORD mode (4M-word by 16-bit)
A0 to A21 are used as 22 bits address signals.
BYTE mode (8M-word by 8-bit)
A0 to A21 are used as the upper 22 bits of total 23 bits of address signal.
(The least significant bit (A1) is combined to O15.)
Data output pins.
O0 to O7, O8 to O14 are used differently in the WORD mode and the BYTE
mode.
WORD mode (4M-word by 16-bit)
The lower 15 bits of 16 bits data outputs to O0 to O14.
(The most significant bit (O15) combined to A1.)
BYTE mode (8M-word by 8-bit)
8 bits data outputs to O0 to O7 and also O8 to O14 are high impedance.
O15, A1 are used differently in the WORD mode and the BYTE mode.
WORD mode (4M-word by 16-bit)
The most significant output data bus (O15).
BYTE mode (8M-word by 8-bit)
The least significant address bus (A1).
Chip activating signal.
When the OE is active, output states are following.
High level: High-Z
Low level : Data out
Output enable signal. The active level of OE is mask option. The active level
of OE can be selected from high active, low active and Don’t care at order.
Supply voltage
Ground
Not internally connected (The signal can be connected).
