IDT7024L15PFG Datasheet PDF - Integrated Device Technology

●Description

●The IDT7024 is a high-speed 4Kx 16 Dual-Port Static RAM. The IDT7024 is designed to be used as a stand-alone 64K-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.

●Features

●◆True Dual-Ported memory cells which allow simultaneous reads of the same memory location

●◆High-speed access

●– Industrial: 55ns (max.)

●– Commercial: 15/17/20/25/35/55ns (max.)

●◆Low-power operation

●– IDT7024S

●  Active: 750mW (typ.)

●  Standby: 5mW (typ.)

●– IDT7024L

●  Active: 750mW (typ.)

●  Standby: 1mW (typ.)

●◆Separate upper-byte and lower-byte control for multiplexed bus compatibility

●◆IDT7024 easily expands data bus width to 32 bits or more using the Master/Slave select when cascading more than one device

●◆M/S= H for BUSYoutput flag on Master

●   M/S= L for BUSYinput on Slave

●◆Interrupt Flag

●◆On-chip port arbitration logic

●◆Full on-chip hardware support of semaphore signaling between ports

●◆Fully asynchronous operation from either port

●◆Battery backup operation—2V data retention

●◆TTL-compatible, single 5V (±10%) power supply

●◆Available in 84-pin PGA, Flatpack, PLCC, and 100-pin Thin Quad Flatpack

●◆Industrial temperature range (–40°C to +85°C) is available for selected speeds

●◆Green parts availble, see ordering information
