709279S12PF8

Memory IC Overview

The Renesas Electronics Corporation 709279S12PF8 is a high-speed, 512Kbit (32K x 16) synchronous dual-port static random-access memory. It operates on a single 5V power supply with an access time of 12 ns and supports frequencies up to 50 MHz. The device features full synchronous operation on both ports, allowing simultaneous access to the same memory location. It offers flow-through or pipelined output modes selectable via the FT/PIPE pin. The component is housed in a 100-pin TQFP package measuring 14x14 mm and is designed for applications requiring unidirectional or bidirectional data flow bursts.

Memory IC Feature Summary

• Dual-Port architecture enables simultaneous independent access to shared memory locations by two distinct controllers.
• Full synchronous operation on both ports ensures precise timing alignment for high-speed data transfer.
• Configurable output mode allows selection between flow-through and pipelined operations via a dedicated control pin.
• Automatic power-down feature controlled by chip enable signals reduces standby power consumption.

Memory IC Applications

• High-speed communication systems requiring burst data buffering
• Network switches and routers utilizing parallel interface protocols
• Industrial automation controllers needing low-latency data exchange

Memory IC Procurement Notes

This component is officially discontinued and no longer in active production. Verification of availability is restricted to existing stock held by distributors or secondary market suppliers. Designers must confirm the specific revision and lot date against current inventory records. Replacement strategies should be initiated immediately as sourcing new units from the manufacturer is not possible. Ensure compatibility with legacy system requirements before procuring remaining stock.

Memory IC Selection Notes

Select this part only for legacy designs requiring a 32K x 16 synchronous dual-port SRAM with 12 ns access time. Verify that the system voltage matches the specified 5V tolerance range. Confirm that the 100-TQFP package dimensions fit the existing PCB footprint. Consider the discontinuation status when planning long-term maintenance. Evaluate alternative components if new design iterations are feasible, as support for this obsolete part will diminish over time.
