7005S17JI8

Overview

The Renesas 7005S17JI8 is a high-speed 64Kbit (8K x 8) dual-port static random-access memory (SRAM). It features asynchronous parallel interfaces with a 17ns access time. The device operates on a single 5V supply within a 4.5V to 5.5V range and supports surface-mount installation in a 68-pin PLCC package. It includes hardware semaphore signaling, interrupt flags, and automatic power-down modes for low standby current.

Feature Summary

• True dual-ported architecture enabling simultaneous independent reads from both ports
• On-chip hardware support for semaphore signaling and port arbitration logic
• Automatic power-down feature controlled by chip enable signals
• TTL-compatible single 5V power supply operation

Applications

• Stand-alone 64K-bit dual-port RAM systems
• Master/Slave dual-port RAM configurations for 16-bit or wider data buses
• Battery backup applications requiring 2V data retention
• Industrial control systems utilizing asynchronous parallel interfaces

Procurement Notes

Verify component authenticity through authorized channels as the part may be discontinued. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for alternate pin-compatible packages if original packaging is unavailable. Validate lead-free specifications against current environmental regulations.

Selection Notes

Select this component for designs requiring true dual-port memory access without external arbitration. Ensure voltage levels match the 4.5V to 5.5V operating range. Consider the 68-pin PLCC footprint for PCB layout constraints. Verify thermal requirements against the specified operating temperature range.
