1 / 20 page FUNCTIONAL BLOCK DIAGRAM • 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 avail- able, tested to military electrical specifications DESCRIPTION: The IDT7015 is a high-speed 8K x 9 Dual-Port Static RAMs. The IDT7015 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 FEATURES: • True Dual-Ported memory cells which allow simulta- neous 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 Integrated Device Technology, Inc. MILITARY AND COMMERCIAL TEMPERATURE RANGES OCTOBER 1996 ©1996 Integrated Device Technology, Inc. DSC-2954/2 HIGH-SPEED 8K x 9 DUAL-PORT STATIC RAM IDT7015S/L NOTES: 1. In MASTER mode: BUSY is an output and is a push-pull driver In SLAVE mode: BUSY is input. 2. BUSY outputs and INT outputs are non-tri-stated push-pull drivers.
