7006L17PF

Overview

The Renesas Electronics Corporation 7006L17PF is a discontinued dual-port static random access memory (SRAM) IC. It features a storage capacity of 128Kb organized as 16K x 8 bits with parallel interface and asynchronous operation. The component has an access time of 17 ns and operates on a single 4.5V to 5.5V power supply. It is housed in a 64-TQFP surface-mount package measuring 14x14 mm. The device supports commercial temperature range from 0°C to 70°C.

Feature Summary

• True dual-ported memory cells allow simultaneous independent reads of the same memory location from either port.
• On-chip hardware support for semaphore signaling enables efficient data synchronization between ports.
• Integrated port arbitration logic manages bus conflicts automatically during concurrent access attempts.
• Automatic power-down feature controlled by chip enable reduces standby power consumption significantly.

Applications

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

Procurement Notes

This component is officially obsolete and no longer manufactured by Renesas Electronics. Verification of authenticity is critical when sourcing remaining stock, as counterfeit parts may circulate. Confirm the specific suffix matches the original specification exactly. Check for RoHS compliance status, as older batches may not meet current environmental regulations. Validate the package integrity and pin alignment before integration into new designs.

Selection Notes

Designers should evaluate the 7006L15PFG as a verified upgrade alternative within the same family. Consider the increased speed and updated manufacturing processes of the replacement part. Ensure that the system timing requirements align with the selected substitute's access times. Verify that the physical footprint and pinout remain compatible with existing PCB layouts to minimize redesign efforts.

Part Context

The 7006 series represents high-speed dual-port SRAMs designed for flexible memory architectures. This specific model utilizes TTL-compatible single 5V supply logic. It supports both standalone and master/slave configurations. The technology allows expansion of data bus widths beyond 8 bits. It includes interrupt flags and busy signals for advanced control.

Replacement Considerations

The 7006L15PFG is listed as an upgrade replacement by the manufacturer.
