Product Summary

The IDT70V09L20PFI is a high-speed 128K x 8 Dual-Port Static RAM. The IDT70V09L20PFI0 is designed to be used as a stand-alone 1024K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-more word system. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. This IDT70V09L20PFI provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power down feature controlled by the chip enables (either CE0 or CE1) permit the on-chip circuitry of each port to enter a very low standby power mode.

Parametrics

IDT70V09L20PFI absolute maximum ratings: (1)Temperature Under Bias: -55 to +125 ℃; (2)TSTG Storage Temperature: -65 to +150 ℃; (3)IOUT DC Output Current: 50 mA; (4)VTERM(2) Terminal Voltage with Respect to GND: -0.5 to +4.6 V.

Features

IDT70V09L20PFI features: (1)True Dual-Ported memory cells which allow simultaneous access of the same memory location; (2)High-speed access; (3)Low-power operation; (4)Dual chip enables allow for depth expansion without external logic; (5)IDT70V09 easily expands data bus width to 16 bits or more using the Master/Slave select when cascading more than one device; (6)M/S = VIH for BUSY output flag on Master, M/S = VIL for BUSY input on Slave; (7)Busy and Interrupt Flags; (8)On-chip port arbitration logic; (9)Full on-chip hardware support of semaphore signaling between ports; (10)Fully asynchronous operation from either port; (11)LVTTL-compatible, single 3.3V (±0.3V) power supply; (12)Available in a 100-pin TQFP; (13)Industrial temperature range (–40°C to +85°C) is available for selected speeds.
