DC Electrical Characteristics Over the Operating

Temperature and Supply Voltage Range(1,6,7) (VCC = 3.3V ± 0.3V)

NOTES:

1. 'X' in part numbers indicates power rating (S or L)

2. VCC = 3.3V, TA = +25°C, and are not production tested. ICCDC = 90mA (Typ.)

3. At f = fMAX

, address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1/tRC, and using “AC Test Conditions" of input levels of GND

to 3V.

4. f = 0 means no address or control lines change.

5. Port "A" may be either left or right port. Port "B" is the opposite from port "A".

6. Refer to Chip Enable Truth Table.

7. Industrial temperature: for specific speeds, packages and powers contact your sales office.
