IDT7015L

• True Dual-Ported memory cells which allow simultaneous access of the same memory location
• High-speed access - Military: 20/25/35ns (max.) - Commercial: 12/15/17/20/25/35ns (max.)
• Low-power operation - IDT7015S Active: 750mW (typ.) Standby: 5mW (typ.) - IDT7015L Active: 750mW (typ.) Standby: 1mW (typ.)
• IDT7015 easily expands data bus width to 18 bits or more using the Master/Slave select when cascading more than one device
• M/S = H for BUSY output flag on Master M/S = L for BUSY input on Slave
• Interrupt and Busy Flags
• On-chip port arbitration logic
• Full on-chip hardware support of semaphore signaling between ports
• Fully asynchronous operation from either port
• Devices are capable of withstanding greater than 2001V electrostatic discharge
• TTL-compatible, single 5V (±10%) power supply
• Available in ceramic 68-pin PGA, 68-pin PLCC, and an 80-pin TQFP
• Industrial temperature range (40°C to +85°C) is available, tested to military electrical specifications

The IDT7015L is a high-speed 8K x 9 Dual-Port Static RAMs. The IDT7015L is designed to be used as stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual- Port RAM for 18-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 18-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.

This IDT7015L provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location inmemory. An automatic power down feature controlled by CE permits the on-chip circuitry of each port to enter a very low standby power mode.

Fabricated using IDT's CMOS high-performance technology, these devices typically operate on only 750mW of power.

The IDT7015L is packaged in a ceramic 68-pin PGA, a 64- pin PLCC and an 80-pin TQFP (Thin Quad FlatPack). Military grade product is manufactured in compliance with the latest revision of MIL-STD-883, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
