7006S12PF8

Overview

The Renesas 7006S12PF8 is a high-speed dual-port static random-access memory (SRAM) with a storage capacity of 128 kbit, organized as 16K x 8. It features an asynchronous parallel interface with a maximum access time of 12 ns. The device operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 64-TQFP package.

Feature Summary

• True dual-ported memory cells enabling simultaneous independent reads from both ports
• On-chip hardware support for semaphore signaling and port arbitration logic
• Automatic power-down mode controlled by chip enable signals for low standby power
• TTL-compatible operation with full interrupt flag functionality

Applications

• Stand-alone 128K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 16-bit or wider data bus expansion
• Battery-backed applications requiring 2V data retention capabilities

Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Verification of availability should focus exclusively on approved substitute part numbers listed in official documentation. Do not assume functional equivalence with generic family members without cross-referencing specific datasheet parameters.

Selection Notes

Engineers replacing this obsolete part must evaluate alternative devices based on identical pinout compatibility, voltage levels, and timing specifications. The replacement must maintain the dual-port architecture and asynchronous interface characteristics required by the original design constraints.

Part Context

The 7006 series represents a line of high-speed dual-port SRAMs designed for complex data sharing between processors. This specific model belongs to the asynchronous subset, offering flexible integration into systems requiring concurrent memory access without clock synchronization overhead.

Replacement Considerations

Official substitution guidance identifies the 7006L15PFG as a manufacturer-recommended alternative. Engineers should verify that the 15 ns access time meets system requirements compared to the original 12 ns specification.
