709079S12PF

Memory IC Overview

The Renesas Electronics Corporation 709079S12PF 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 power supply with TTL-compatible inputs and outputs. It supports flow-through or pipelined output modes selectable via the FT/PIPE pin. The component utilizes registered inputs for minimal setup and hold times, enabling fast cycle times. It includes counter enable and reset features for address generation and depth expansion capabilities using dual chip enables.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to any memory location from both ports.
• Full synchronous operation on both ports with registered control, data, and address inputs for minimal timing constraints.
• Selectable flow-through or pipelined output modes on either port via the dedicated FT/PIPE pin.
• Integrated address counter with enable and reset features for automated sequential addressing.

Memory IC Applications

• High-speed burst data transfer applications requiring unidirectional or bidirectional data flow
• Systems utilizing depth expansion configurations without additional external logic
• Fast interleaved memory applications requiring address counter functionality

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature range. Confirm RoHS compliance status as older manufacturing runs may differ. Check for end-of-life notices or obsolescence declarations prior to finalizing procurement plans. Ensure voltage levels align with the specified 5V ±10% requirement for reliable operation.

Memory IC Selection Notes

Select this component when a synchronous dual-port interface is required for high-speed data buffering. Choose the S variant for standard power consumption or L variant for low-power standby requirements. Verify that the 12ns speed grade meets the system clock frequency needs. Ensure the 100-pin TQFP package fits the available PCB footprint and thermal constraints.

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 a reduced density of 32K x 8 bits. The device is manufactured using CMOS technology optimized for performance and power efficiency. It serves as a direct replacement for legacy IDT parts within the same functional family.
