Features, Applications

True Dual-Ported memory cells which allow simultaneous access of the same memory location High-speed access Commercial: 15/20/25/35/55ns (max.) Industrial: 20/25/35/55ns (max.) Military: 20/25/35/55ns (max.) Low-power operation IDT7026S Active: 750mW (typ.) Standby: 5mW (typ.) IDT7026L Active: 750mW (typ.) Standby: 1mW (typ.) Separate upper-byte and lower-byte control for multiplexed bus compatibility

IDT7026 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 BUSY output flag on Master, M/S = L for BUSY input on Slave On-chip port arbitration logic Full on-chip hardware support of semaphore signaling between ports Fully asynchronous operation from either port TTL-compatible, single 5V (10%) power supply Available in 84-pin PGA and 84-pin PLCC Industrial temperature range +85C) is available for selected speeds

NOTES: 1. (MASTER): BUSY is output; (SLAVE): BUSY is input. 2. BUSY outputs are non-tri-stated push-pull.

The is a high-speed x 16 Dual-Port Static RAM. The IDT7026 is designed to be used as a stand-alone Dual-Port RAM as a combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach 32bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. This device 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 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 IDT7026 is packaged in a ceramic 84-pin PGA, and a 84-pin PLCC. Military grade product is manufactured in compliance with the latest revision of MIL-PRF-38535 QML, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
