709079S12PFI

Memory IC Overview

The Renesas Electronics Corporation 709079S12PFI 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 flow-through or pipelined output modes selectable via the FT/PIPE pin, with a maximum clock-to-data access time of 12ns for 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 any memory address from both ports
• Configurable flow-through or pipelined output modes controlled by the FT/PIPE pin
• Integrated address counter with enable and reset features for burst data flow applications
• Dual chip enables facilitating depth expansion without additional external logic

Memory IC Applications

• High-speed unidirectional or bidirectional data flow bursts
• Interleaved memory applications requiring fast cycle times
• Depth expansion configurations using multiple devices
• Systems requiring simultaneous read/write operations on shared memory locations

Memory IC Procurement Notes

Verify that the specific ordering suffix PFI corresponds to the 100-pin TQFP package and tray packaging format as defined in official documentation. Confirm the 'I' suffix indicates the industrial temperature range availability if required, noting that the base 12ns speed grade may have specific commercial versus industrial availability constraints. Ensure compatibility with the 5V supply voltage and TTL input levels before integration.

Memory IC Selection Notes

Select this component when simultaneous access to identical memory addresses from two distinct ports is required. The choice between flow-through and pipelined modes depends on system latency requirements and bus synchronization needs. Verify that the 12ns access time meets the target clock frequency specifications. Ensure the design accommodates the 100-pin TQFP footprint and adheres to the single 5V power supply constraint.

Memory IC Part Context

This part belongs to the IDT709089/79 family of high-speed synchronous dual-port SRAMs. The 709079 variant specifically provides a 32K x 8 organization, distinguishing it from the 64K x 8 capacity of the 709089 model. Both share similar architectural features including registered inputs, low-power operation modes, and compatible packaging options within the 100-pin TQFP form factor.

Memory IC Replacement Considerations

Direct substitutes include other members of the IDT709089/79 series such as the 709079L12PFI for industrial temperature ranges or lower power variants. Cross-manufacturer replacements must match the 32K x 8 density, 100-pin TQFP package, and synchronous dual-port interface characteristics.
