SN74V283-6PZA

FIFOs Memory Overview

The SN74V283-6PZA is a synchronous first-in, first-out (FIFO) memory fabricated using high-performance submicron CMOS technology. It provides a storage capacity of 32768 words by 18 bits or 65536 words by 9 bits. The device supports independent read and write clocks with a maximum operating frequency of 166 MHz and features a typical access time of 6 ns. It operates within a supply voltage range of 3.15 V to 3.45 V and includes user-selectable bus sizing, big-endian/little-endian byte representation, and programmable status flags.

FIFOs Memory Feature Summary

• Supports flexible data flow matching between input and output ports with selectable ×9 or ×18 bus widths.
• Features zero-latency retransmit capability allowing previously read data to be reread from the start of the memory array.
• Includes programmable almost-empty and almost-full flags that can be configured via serial or parallel methods.

FIFOs Memory Applications

• Buffering large amounts of data in telecommunications systems
• Matching buses of unequal sizes in network applications
• Video processing data buffering
• Data communications interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix '6' against the manufacturer's official documentation to confirm the exact speed grade and timing characteristics. Confirm the package designation matches the required 80-pin Thin Quad Flat Pack (TQFP) physical dimensions. Ensure environmental compliance requirements align with the RoHS status specified in the current production data sheet.

FIFOs Memory Selection Notes

Select this component when deep memory depth combined with high-speed operation is required for asynchronous clock domain crossing. Consider the SN74V283 over other family members if the specific 32768 x 18 organization fits the design constraints. Evaluate the need for programmable flag offsets and retransmit functions before finalizing the part choice.

FIFOs Memory Part Context

This device belongs to the SN74V2xx series of 3.3-V CMOS FIFO memories manufactured by Texas Instruments. The series includes variants with different depths such as the SN74V263, SN74V273, and SN74V293. These components are designed for glueless interfacing with high-performance processors like DSPs and utilize high-speed submicron CMOS technology for low power consumption and fast switching speeds.
