IDT70V28L General Description

The IDT70V28 is a high-speed 64K x 16 Dual-Port Static RAM. he IDT70V28 is designed to be used as a stand-alone 1024K-bit ual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM or 32-bit-or-more word system. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 32-bit or wider memory system applications esults in full-speed, error-free operation without the need for additional iscrete logic.

This device provides two independent ports with separate control, ddress, and I/O pins that permit independent, asynchronous access or reads or writes to any location in memory. An automatic power own feature controlled by the chip enables (either CE₀ or CE₁) ermit the on-chip circuitry of each port to enter a very low standby wer mode.

Fabricated using IDT's CMOS high-performance technology, hese devices typically operate on only 440mW of power.

The IDT70V28 is packaged in a 100-pin Thin Quad Flatpack TQFP).

IDT70V28L Maximum Ratings

Symbol	Rating	Commercial & Industrial	Unit
V_TERM⁽²⁾	Terminal Voltage with Respect to GND	-0.5 to +4.6	V
T_BIAS	Temperature Under Bias	55 to +125
T_STG	Storage Temperature	65 to +150
I_OUT	DC Output Current	50	mA

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may ause permanent damage to the device. This is a stress rating only and functional peration of the device at these or any other conditions above those indicated in he operational sections of this specification is not implied. Exposure to absolute aximum rating conditions for extended periods may affect reliability.
2. V_TERM must not exceed Vcc + 0.3V for more than 25% of the cycle time or 10ns aximum, and is limited to 20mA for the period of V_TERM Vcc + 0.3V.
