2 / 22 page  6.42 2 IDT70V7339S High-Speed 512K x 18 Synchronous Bank-Switchable Dual-Port Static RAM Industrial and Commercial Temperature Ranges Description: The IDT70V7339 is a high-speed 512Kx18 (9Mbit) synchronous Bank-Switchable Dual-Ported SRAM organized into 64 independent 8Kx18 banks. The device has two independent ports with separate control,address,andI/Opinsforeachport,allowingeachporttoaccess any 8Kx18 memory block not already accessed by the other port. Accesses by the ports into specific banks are controlled via the bank address pins under the user's direct control. Registersoncontrol,data,andaddressinputsprovideminimalsetup and hold times. The timing latitude provided by this approach allows systems to be designed with very short cycle times. With an input data Pin Configuration(1,2,3,4) NOTES: 1.
