SN74V215-15PAG

Overview

The SN74V215-15PAG is a synchronous FIFO memory with a 512 x 18-bit organization, packaged in a 64-pin TQFP. It operates on a 3.3-V supply and supports clock frequencies up to 133 MHz with read-access times as fast as 5 ns. The device features asynchronous or coincident read/write clocks, programmable almost-empty and almost-full flags, and first-word fall-through or standard timing modes.

Feature Summary

• Supports asynchronous or coincident read and write clocks for flexible interface control.
• Features single or double register-buffered empty and full flags for status monitoring.
• Includes programmable almost-empty and almost-full flags with default settings.
• Provides half-full flag capability and output enable for high-impedance state control.

Applications

• DSP-to-processor communication
• DSP-to-analog front end buffering
• Network data communications

Procurement Notes

Verify the specific ordering suffix '15PAG' against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with 3.3-V logic levels and check for any recent lifecycle status changes before finalizing procurement plans.

Selection Notes

Select this component when a 512 x 18-bit synchronous FIFO is required. Consider the SN74V225, SN74V235, or SN74V245 if greater memory depth is needed. Verify that the 64-pin TQFP package fits the PCB layout constraints and that the 0°C to 70°C operating range meets environmental requirements.

Part Context

This part belongs to the SN74V215/225/235/245 family of DSP-SYNC FIFO memories. These devices are designed for high-speed, low-power applications using submicron CMOS technology. They provide glueless interfaces for Texas Instruments TMS320 DSPs and support easy expansion in depth and width.

Replacement Considerations

Public confirmed substitutes include SN74V225-15PAG, SN74V235-15PAG, and SN74V245-15PAG from Texas Instruments, which offer increased memory depths while maintaining similar interface characteristics.
