SN74V263-7PZA

Overview

The SN74V263 is a high-speed, deep CMOS first-in, first-out (FIFO) memory with an 8192 × 18 or 16384 × 9 organization. It operates at frequencies up to 166 MHz with a 6-ns read/write cycle time. The device features user-selectable input and output bus sizing for flexible data flow matching. It supports big-endian/little-endian byte representation and includes programmable almost-empty and almost-full flags. Independent read and write clocks allow simultaneous operations.

Feature Summary

• Supports user-selectable input and output port bus sizing for flexible data flow matching
• Features independent read and write clocks permitting simultaneous reading and writing
• Includes programmable almost-empty and almost-full flags with selectable timing modes
• Provides big-endian/little-endian user-selectable byte representation

Applications

• Network buffering applications requiring large data storage
• Video processing systems needing bus size matching
• Telecommunications equipment utilizing FIFO memory
• Data communications interfaces

Procurement Notes

Verify the specific package type against the ordering suffix PZA, which corresponds to the 100-pin Ball Grid Array (BGA). Confirm that the required memory organization matches the SN74V263 specifications of 8192 × 18 or 16384 × 9. Ensure the design supports the necessary control signals for master reset and flag programming as documented in the datasheet.

Selection Notes

Select this component when deep memory depth and high-speed operation are required. It is suitable for interfacing with DSPs via glueless connections. Consider the available bus configurations if width mismatching between input and output ports is needed. Verify that the 3.3-V supply voltage aligns with the system requirements.

Part Context

This part belongs to the SN74V2xx family of high-speed CMOS FIFO memories from Texas Instruments. These devices are designed for high-performance applications requiring significant data buffering capabilities. The family includes variants with different memory depths to accommodate various system constraints.
