Input / Output Pin Functions
Pin name
WORD, /BYTE
Input / Output
Input
Function
The pin for switching WORD mode and BYTE mode.
High level
: WORD mode (1M-word by 16-bit)
Low level
: BYTE mode (2M-word by 8-bit)
A0 to A19
(Address inputs)
Input
Address input pins.
A0 to A19 are used differently in the WORD mode and the BYTE mode.
WORD mode (1M-word by 16-bit)
A0 to A19 are used as 20 bits address signals.
BYTE mode (2M-word by 8-bit)
A0 to A19 are used as the upper 20 bits of total 21 bits of address signal.
(The least significant bit (A−1) is combined to O15.)
O0 to O7, O8 to O14
(Data outputs)
Output
Data output pins.
O0 to O7, O8 to O14 are used differently in the WORD mode and the BYTE mode.
WORD mode (1M-word by 16-bit)
The lower 15 bits of 16 bits data outputs to O0 to O14.
(The most significant bit (O15) combined to A−1.)
BYTE mode (2M-word by 8-bit)
8 bits data outputs to O0 to O7 and also O8 to O14 are high impedance.
O15, A−1
(Data output 15,
LSB Address input)
Output, Input
O15, A−1 are used differently in the WORD mode and the BYTE mode.
WORD mode (1M-word by 16-bit)
The most significant output data bus (O15).
BYTE mode (2M-word by 8-bit)
The least significant address bus (A−1).
/CE
(Chip Enable)
Input
Chip activating signal.
When the OE is active, output states are following.
High level
: High-Z
Low level
: Data out

Input
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
