2 / 22 page 6.42 IDT70V24S/L High-Speed 4K x 16 Dual-Port Static RAM Industrial and Commercial Temperature Ranges 2 Description The IDT70V24 is a high-speed 4K x 16 Dual-Port Static RAM. The IDT70V24isdesignedtobeusedasastand-alone64K-bitDual-PortRAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more wordsystems.UsingtheIDTMASTER/SLAVEDual-PortRAMapproach in 32-bit or wider memory system applications results in full-speed, error- free operation without the need for additional discrete logic. Thisdeviceprovidestwoindependentportswithseparatecontrol, address,andI/Opinsthatpermitindependent,asyn-chronousaccessfor reads or writes to any location in memory. An automatic power down feature controlled by CE permitstheon-chipcircuitryofeachporttoenter a very low standby power mode. Fabricated using IDT’s CMOS high-performance technology, these devices typically operate on only 400mW of power. The IDT70V24 is packaged in a ceramic 84-pin PGA, an 84-Pin PLCC and a 100-pin Thin Quad Flatpack. Pin Configurations(1,2,3) NOTES: 1. All VCC pins must be connected to power supply. 2. All GND pins must be connected to ground supply. 3. J84-1 package body is approximately 1.15 in x 1.15 in x .17 in. PN100-1 package body is approximately 14mm x 14mm x 1.4mm. 4. This package code is used to reference the package diagram. 5.
