7026L15JG IC SRAM 256KBIT PARALLEL 84PLCC Renesas Electronics America Inc

Description

The IDT7026 is a high-speed 16K x 16 Dual-Port Static RAM. The IDT7026 is designed to be used as a stand-alone 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
access of the same memory location

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 (-40°C to +85°C) is available
for selected speeds
◆ Green parts available, see ordering information
