Description

◆

The IDT7133/7143 are high-speed 2K x 16 Dual-Port Static RAMs.

The IDT7133is designedtobe usedas a stand-alone 16-bitDual-Port

RAM or as a “MASTER” Dual-Port RAM together with the IDT7143

“SLAVE” Dual-Port in 32-bit-or-more word width systems. Using the

IDT MASTER/SLAVE Dual-Port RAM approach in 32-bit-or-wider

NOTE:

1. IDT7133 (MASTER): BUSY is open drain output and requires pull-up resistor.

IDT7143 (SLAVE): BUSY is input.
