7008S12PFI

Memory IC Overview

The Renesas Electronics Corporation 7008S12PFI is a high-speed, asynchronous dual-port static RAM featuring a 512Kb capacity organized as 64K x 8. It operates on a single 5V supply within the 4.5V to 5.5V range and delivers a 12ns access time. The component is housed in a 100-pin TQFP package with dimensions of 14x14mm. Designed for industrial applications, it supports an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes from either port without bus contention.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between ports.
• Automatic power-down feature controlled by chip enable signals to minimize standby power consumption.
• TTL-compatible interface allowing direct connection to standard digital logic systems.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation controllers

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as this specific part may not meet current environmental standards. Validate package integrity upon receipt to ensure pin alignment matches the 100-TQFP specification before integration into assembly processes.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration overhead. Ensure system voltage remains within the specified 4.5V to 5.5V window. Consider thermal management for industrial environments exceeding standard commercial limits. Verify that the 12ns speed meets the timing constraints of the host processor interface.

Memory IC Part Context

This device belongs to the IDT7008 series of dual-port SRAMs, originally developed by Integrated Device Technology and now manufactured by Renesas. The series provides standalone or master/slave configurations for expanding data bus widths. The 7008S12 variant specifically denotes the 12ns speed grade within the 512Kb density family.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, verify compatibility with equivalent dual-port SRAMs from other manufacturers based on pinout and electrical specifications.
