IDT72V815
Overview
The IDT72V805/72V815/72V825/72V835/72V845 are dual 18-bit-wide synchronous (clocked) First-in, First-out (FIFO) memories designed to run off a 3.3V supply for exceptionally low power consumption. One dual IDT72V805/72V815/72V825/72V835/72V845 device is functionally equivalent to two IDT72V205/72V215/72V225/72V235/72V245 FIFOs in a single package with all associated control, data, and flag lines assigned to independent pins.
- The IDT72V805 is equivalent to two IDT72V205 256 x 18 FIFOs The IDT72V815 is equivalent to two IDT72V215 512 x 18 FIFOs The IDT72V825 is equivalent to two IDT72V225 1,024 x 18 FIFOs The IDT72V835 is equivalent to two IDT72V235 2,048 x 18 FIFOs The IDT72V845 is equivalent to two IDT72V245 4,096 x 18 FIFOs Offers optimal combination of large capacity (8K), high speed, design flexibility, and small footprint Ideal for the following applications: - Network switching - Two level prioritization of parallel data - Bidirectional data transfer - Bus-matching between 18-bit and 36-bit data paths - Width expansion to 36-bit per package - Depth expansion to 8,192 words per package 10 ns read/write cycle time 5V input tolerant IDT Standard or First Word Fall Through timing Single or double register-buffered Empty and Full Flags * * * * * * *
- Easily expandable in depth and width Asynchronous or coincident Read and Write Clocks Asynchronous or synchronous programmable Almost-Empty and Almost-Full flags with default settings Half-Full flag capability Output enable puts output data bus in high-impedance state High-performance submicron CMOS technology Available in a 128-pin thin quad flatpack (TQFP) Industrial temperature range (-40°C to +85°C) is available
