709279S12PF

Memory IC Overview

The 709279S12PF is a 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 with a parallel interface. The device supports a supply voltage range of 4.5V to 5.5V and has a maximum access time of 12 ns. It operates within a temperature range of 0°C to +70°C and is housed in a 100-TQFP surface-mount package.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from both ports
• Enables depth expansion through dual chip enable functionality without additional logic
• Provides automatic power-down modes controlled by specific chip enables for low standby power

Memory IC Applications

• High-speed data buffering in burst transfer systems
• Bidirectional data flow applications requiring concurrent port access
• Unidirectional data flow optimization in synchronous memory architectures

Memory IC Procurement Notes

Verify component authenticity due to discontinuation status. Confirm moisture sensitivity level handling requirements during assembly. Check for RoHS compliance variations across production lots. Validate pinout compatibility with target PCB layout. Ensure supply chain sources provide original manufacturer documentation.

Memory IC Selection Notes

Evaluate thermal performance within the specified operating temperature range. Consider interface timing constraints relative to system clock speeds. Assess power consumption profiles against available supply rails. Verify package dimensions fit mechanical enclosure constraints. Review end-of-life notices for long-term availability implications.

Memory IC Part Context

This component belongs to the 709279 series of synchronous dual-port RAM devices. It shares architectural similarities with other members like the 709279L12PFGI but differs in speed grade and temperature rating. The series is designed for high-performance memory applications requiring concurrent read/write operations.
