Product Summary

The IDT7028L20PF is a high-speed 64K x 16 Dual-Port Static RAM. The IDT7028L20PF is designed to be used as a stand-alone 1024K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 32-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.

Parametrics

IDT7028L20PF absolute maximum ratings: (1)Terminal Voltage with Respect to GND:-0.5 to +7.0 V; (2)Temperature Under Bias: -55 to +125℃; (3)Storage Temperature:-65 to +150℃; (4)DC Output Current:50 mA.

Features

IDT7028L20PF features: (1)M/S = VIH for BUSY output flag on Master,; (2)M/S = VIL for BUSY input on Slave; (3)Interrupt Flag; (4)On-chip port arbitration logic; (5)Full on-chip hardware support of semaphore signaling between ports; (6)Fully asynchronous operation from either port; (7)Separate upper-byte and lower-byte controls for multiplexed bus and bus matching compatibility; (8)TTL-compatible, single 5V (±10%) power supply; (9)Available in a 100-pin TQFP; (10)Industrial temperature range (–40 to +85℃) is available for selected speeds.
