Overview

The IDT7133/7143 are high-speed 2K x 16 Dual-Port Static RAMs. The IDT7133 is designed to be used as a stand-alone 16-bit Dual-Port RAM or as a “MASTER” Dual-Port RAM together with the IDT7143 “SLAVE” Dual-Port in 32-bit-or-more word width systems.

High-speed access - Military: 35/55/70/90ns (max.) - Industrial: 25ns (max.) - Commercial: 20/25/35/45/55/70/90ns (max.)
Low-power operation - IDT7133/43SA Active: 1150mW (typ.) Standby: 5mW (typ.) - IDT7133/43LA Active: 1050mW (typ.) Standby: 1mW (typ.)
Versatile control for write: separate write control for lower and upper byte of each port Functional Block Diagram R/WLUB CEL
MASTER IDT7133 easily expands data bus width to 32 bits or more using SLAVE IDT7143
On-chip port arbitration logic (IDT7133 only)
BUSY output flag on IDT7133; BUSY input on IDT7143
Fully asynchronous operation from either port
Battery backup operation-2V data retention
TTL-compatible; single 5V (±10%) power supply
Available in 68-pin ceramic PGA, Flatpack, PLCC and 100- pin TQFP
