IDT707288S20PF

HIGH-SPEED 64K x 16 BANK-SWITCHABLE DUAL-PORTED SRAM WITH EXTERNAL BANK SELECTS

Integrated Device Technology 

IDT707288S/L

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

Depth and Width Expansion

The IDT707288 features dual chip enables (refer to Truth Table I) in

order to facilitate rapid and simple depth expansion with no requirements

for external logic. Figure 4 illustrates how to control the various chip

enables in order to expand two devices in depth.

The IDT707288 can also be used in applications requiring expanded

Industrial and Commercial Temperature Ranges

width, as indicated in Figure 4. Since the banks are allocated at the

discretion of the user, the external controller can be set up to drive the input

signals for the various devices as required to allow for 32-bit or wider

applications.
