IDT70P9268

Very Low Power 16K x 16 Synchronous Mobile Multimedia Interface (M2I) Dual Port Static RAM

Industrial Temperature Range

DC Electrical Characteristics Over the Operating Temperature and Supply

Voltage Range (VDD = 1.8V +/- 100mV)

NOTES:

1. At f = fMAX, address and control lines (except Output Enable) are cycling at the maximum frequency clock cycle of 1/tCYC, using “AC TEST CONDITIONS” at input levels of GND to 1.8V.

2. f = 0 means no address, clock, or control lines change. Applies only to input at CMOS level standby.

3. Port “A” may be either left or right port. Port “B” is the opposite from port “A”.
