709079S9PF8

Memory IC Overview

The Renesas Electronics Corporation 709079S9PF8 is a high-speed 32K x 8-bit synchronous dual-port static RAM. It features true dual-ported memory cells allowing simultaneous access to the same location from both ports. The device operates on a single 5V (±10%) power supply and supports TTL-compatible logic levels. It offers a maximum clock-to-data access time of 9 ns in commercial temperature grades. The component is housed in a 100-pin Thin Quad Flatpack (TQFP) package.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent access to shared memory locations by both ports.
• Full synchronous operation on both ports with registered address, data, and control inputs for minimal setup times.
• Configurable Flow-Through or Pipelined output modes selectable via dedicated FT/PIPE pins.
• Integrated address counter with enable and reset features for automated sequential addressing.

Memory IC Applications

• High-speed burst data flow applications requiring unidirectional or bidirectional transfer
• Systems utilizing depth expansion configurations through dual chip enables
• Interfaces requiring fast interleaved memory operations with automatic address generation

Memory IC Procurement Notes

Verify that the specific ordering suffix PF8 corresponds to the Tape and Reel packaging format as indicated in the official IDT/Renesas documentation. Confirm the 'S' designation aligns with standard power consumption requirements rather than low-power variants. Ensure compatibility with the required commercial operating temperature range before procurement.

Memory IC Selection Notes

Select this component when a synchronous interface with registered inputs is required to minimize timing constraints. The dual-port capability allows concurrent read/write operations without arbitration logic. Verify that the 5V supply voltage matches the system design, as the device is not compatible with 3.3V logic levels.

Memory IC Part Context

This part belongs to the IDT709089/79 family of high-speed synchronous dual-port SRAMs. It represents the 32K x 8 density variant within the series, distinct from the 64K x 8 configuration. The device utilizes CMOS high-performance technology to achieve low power consumption while maintaining high-speed data throughput capabilities.

Memory IC Replacement Considerations

Cross-reference with other members of the IDT709089/79 family for alternative speed grades or packaging options. Verify functional equivalence if substituting with generic synchronous dual-port RAM devices, ensuring pinout and timing parameters match.
