SN74V293-15PZA

FIFOs Memory Overview

The SN74V293-15PZA is a 65536 × 18 synchronous FIFO memory fabricated using high-performance submicron CMOS technology. It operates at a maximum clock frequency of 166 MHz with a read/write cycle time of 6 ns. The device supports independent read and write clocks, allowing simultaneous operations. It features user-selectable bus sizing for both input and output ports, supporting configurations from ×9 to ×18 bits. The memory organization can be configured as 65536 × 18 or 131072 × 9.

FIFOs Memory Feature Summary

• Supports flexible bus matching with selectable input and output port widths ranging from 9-bit to 18-bit.
• Features first-word fall-through (FWFT) and standard timing modes for data access control.
• Includes programmable almost-empty and almost-full flags with selectable asynchronous or synchronous timing.
• Provides zero-latency retransmit capability to reread data starting from the first memory location.

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 '15' against official Texas Instruments documentation to confirm speed grade or package variant accuracy. Ensure the PZA package designation matches the required 80-pin Thin Quad Flat Pack specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before ordering.

FIFOs Memory Selection Notes

Select this component when deep memory depth and high-speed operation are required for data buffering. Consider the SN74V293 family if independent read/write clocks and flexible bus width matching are necessary. Evaluate the FWFT mode benefits for latency-sensitive applications compared to standard timing modes.

FIFOs Memory Part Context

The SN74V293 belongs to the SN74V263/273/283/293 family of 3.3-V CMOS FIFO memories. These devices share common architectural features such as submicron CMOS fabrication and 5-V tolerant inputs. The family offers varying memory depths, with the SN74V293 providing the largest capacity among the listed options.
