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.
4. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
5. Refer to Truth Table I - Chip Enable.
DC Electrical Characteristics Over the Operating
Temperature and Supply Voltage Range (VCC = 3.3V ± 0.3V)
NOTES:
1. At Vcc
< 2.0V, input leakages are undefined.
2. Refer to Truth Table I -
Chip Enable.
