709279S12PFI

Memory IC Overview

The 709279S12PFI is a high-speed synchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 512 kbit organized as 32K x 16 bits. The device supports parallel interface operation with a maximum access time of 12 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and functions at temperatures between 0°C and +70°C. The component is housed in a 100-pin TQFP package.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location from two separate ports.
• Full synchronous operation on both ports utilizing a single clock signal for data transfer control.
• Automatic power-down feature controlled by chip enable signals to minimize standby power consumption.

Memory IC Applications

• High-speed data buffering in network communication systems
• FIFO buffer applications requiring unidirectional or bidirectional burst data flow
• Embedded systems requiring low-latency memory access

Memory IC Procurement Notes

Verify RoHS compliance status, as documentation indicates non-compliance. Confirm moisture sensitivity level (MSL 3) requirements for surface-mount assembly processes. Check for end-of-life notices or obsolescence warnings prior to final design approval. Ensure availability of compatible replacement packages if tray quantities are required.

Memory IC Selection Notes

Select this component when a 512 kbit synchronous dual-port SRAM with 12 ns access speed is required. Ensure the system operates within the 4.5 V to 5.5 V voltage range. Verify that the 100-pin TQFP footprint matches the PCB layout. Consider industrial temperature variants if operation below 0°C is necessary.

Memory IC Part Context

This part belongs to the 709279 series of synchronous dual-port RAMs. It shares architectural similarities with other members like the 709279L12PFI but differs in operating temperature range and specific suffix designations. The 'S' designation typically denotes commercial temperature grades compared to 'L' for industrial ranges.

Memory IC Replacement Considerations

IDT709279S12PF8 is listed as an alias. Verify pinout compatibility before substitution. No other direct substitutes are confirmed in public documentation.
