709079L9PF

Memory IC Overview

The Renesas Electronics 709079L9PF is a 256K-bit (32K x 8) synchronous dual-port static RAM. It operates on a single 5V power supply with an access time of 9ns. The device supports both flow-through and pipelined output modes via the FT/PIPE pin, allowing for optimized data flow in burst applications. It features true dual-ported memory cells enabling simultaneous access to the same location from both ports. The component is housed in a 100-pin TQFP package.

Memory IC Feature Summary

• True dual-ported memory architecture allows simultaneous independent access to any address from both ports without conflict.
• Configurable output mode selectable between flow-through and pipelined operation using the dedicated FT/PIPE control pin.
• Integrated address counter with enable and reset functions facilitates sequential data processing and interleaved memory applications.
• Dual chip enables permit depth expansion configurations without requiring additional external logic gates.

Memory IC Applications

• High-speed data buffering in communication systems
• FIFO buffer implementations for unidirectional or bidirectional burst data flows
• Cache memory subsystems requiring low-latency access

Memory IC Procurement Notes

Verify the specific suffix 'PF' corresponds to the 100-pin TQFP package configuration. Confirm that the 'L' designation indicates the low-power variant with typical standby current of 1mW. Ensure the 9ns speed grade matches the required system timing constraints. Check RoHS compliance status as indicated in the ordering information.

Memory IC Selection Notes

Select this component when a synchronous interface is required for dual-port memory operations. The 9ns speed grade suits high-frequency bus architectures. Consider the low-power option if thermal management is critical. Verify that the 5V supply voltage aligns with the system's power rails before integration.

Memory IC Part Context

This part belongs to the IDT709089/79 family of high-speed synchronous dual-port SRAMs. It shares architectural similarities with the 64K x 8 variant but offers half the density. The device utilizes CMOS technology for performance and is designed for applications demanding fast cycle times and registered inputs.

Memory IC Replacement Considerations

IDT709079S9PF serves as a standard power alternative within the same speed grade. Other compatible parts include IDT709079L12PF for slower 12ns requirements. Verify pin compatibility and electrical characteristics before substituting.
