IDT70V28L

High-Speed 3.3V 64K x 16 Dual-Port Static RAM

Industrial and Commercial Temperature Ranges

DC Electrical Characteristics Over the Operating

Temperature and Supply Voltage Range(5) (VCC = 3.3V ± 0.3V)

NOTES:

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

2. 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.

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