709279L15PF

Memory IC Overview

The IDT709279L15PF is a high-speed 32K x 16 bit synchronous Dual-Port Static RAM. It features a 15 ns access time and operates on a single 5V power supply with TTL-compatible I/O. The device supports both flow-through and pipelined output modes, selectable via the FT/PIPE pin. It includes counter enable and reset features, dual chip enables for depth expansion, and separate upper-byte/lower-byte controls. The component is housed in a 100-pin TQFP package (14x14 mm) and supports an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture allows simultaneous independent access to memory locations from two distinct ports.
• Configurable output mode supports either direct flow-through or pipelined data transfer operations.
• Integrated automatic power-down capability reduces standby current when chip selects are inactive.
• Full synchronous operation on both ports ensures timing compatibility with standard system clocks.

Memory IC Applications

• Network routers and switches requiring high-bandwidth packet buffering
• Telecommunications equipment utilizing burst data flow architectures
• Industrial control systems needing reliable bidirectional data exchange
• Embedded computing platforms requiring fast local memory expansion

Memory IC Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm exact speed grade, temperature range, and packaging type. Confirm RoHS compliance status as older revisions may differ. Check current lifecycle status, as this part number may be obsolete or subject to last-time buy restrictions. Ensure the selected variant matches the required voltage and interface specifications for the target application design.

Memory IC Selection Notes

Select this component when a synchronous dual-port SRAM with 512Kb density is required for high-speed data buffering. Compare access times and power consumption against alternative parts if lower latency is critical. Verify that the 100-pin TQFP footprint fits the PCB layout constraints. Consider the availability of pipelined versus flow-through modes based on the system's clock domain requirements and bus synchronization needs.

Memory IC Part Context

This device belongs to the IDT 709279 family of synchronous dual-port RAMs. Variants within this series typically share the same 32K x 16 organization and 100-pin TQFP package but differ in access speed grades and temperature ranges. The family is designed for applications demanding high throughput and low latency in network and telecommunications infrastructure.
