SN74V293-7PZA

FIFOs Memory Overview

The SN74V293-7PZA is a synchronous first-in, first-out (FIFO) memory device manufactured by Texas Instruments. It features a storage capacity of 65536 x 18 bits or 131072 x 9 bits. The component supports a maximum clock frequency of 166 MHz and has an access time of 6 ns. It operates within a supply voltage range of 3.15 V to 3.45 V. The device is housed in an 80-pin Thin Quad Flat Pack (TQFP) package.

FIFOs Memory Feature Summary

• Supports user-selectable input and output port bus sizing for flexible data flow matching.
• Provides big-endian and little-endian user-selectable byte representation.
• Features zero-latency retransmit capability for rereading data from the FIFO.

FIFOs Memory Applications

• Network buffering applications
• Video processing systems
• Telecommunications equipment
• Data communications interfaces

FIFOs Memory Procurement Notes

Verify the specific speed grade suffix '7' against official datasheets to confirm performance parameters. Ensure the PZA package designation matches the required 80-pin TQFP form factor. Confirm RoHS compliance status through manufacturer documentation before procurement.

FIFOs Memory Selection Notes

Select this component when deep memory depth and high-speed operation are required. Consider the independent read and write clocks for simultaneous data handling. Evaluate the programmable flag offsets for precise buffer management needs.

FIFOs Memory Part Context

This part belongs to the SN74V263, SN74V273, SN74V283, and SN74V293 family of 3.3-V CMOS FIFO memories. These devices utilize high-performance submicron CMOS technology. They are designed for glueless interfacing with DSPs such as the C6x series.

FIFOs Memory FAQ

How is the bus width configured?

The input and output bus widths are selectable between 9-bit and 18-bit configurations using the IW and OW pins during the master reset cycle.

What timing modes are supported?

The device supports standard timing mode and First-Word Fall-Through (FWFT) mode, which is selected via the FWFT/SI pin during master reset.
