13.1 AC Test Conditions
Note:
1. Including scope and socket capacitance.

Notes
Min.
Notes:
It is possible to control data width by S-LB and S-UB pins.
1. Reading data from lower byte
Data can be read when the address is set while holding S-CE
1
= Low, S-CE
2
= High, S-OE = Low, S-WE = High and
S-LB = Low.
2. Reading data from upper byte
Data can be read when the address is set while holding S-CE
1
= Low, S-CE
2
= High, S-OE = Low, S-WE = High and
S-UB = Low.
3. Reading data from both bytes
Data can be read when the address is set while holding S-CE
1
= Low, S-CE
2
= High, S-OE = Low, S-WE = High,
S-LB = Low and S-UB = Low.
