7008S12JI

Memory IC Overview

The Renesas 7008S12JI is a high-speed 512Kbit dual-port static RAM designed for parallel interface applications. It features an access time of 12 ns and operates on a single 5V power supply within the 4.5V to 5.5V range. The device utilizes true dual-ported memory cells allowing simultaneous reads from the same location. It is housed in an 84-pin PLCC package with J-leads, suitable for surface mount installation.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent access to memory locations
• On-chip hardware support for semaphore signaling and port arbitration logic
• Automatic power-down feature controlled by chip enable for low standby power
• TTL-compatible operation with a single 5V power supply

Memory IC Applications

• Stand-alone 512k-bit dual-port RAM systems
• Master/slave dual-port configurations for 16-bit or wider word systems
• High-speed data buffering in asynchronous processing environments

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part may be discontinued. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for obsolescence notices and ensure adequate lead times for legacy sourcing. Validate package dimensions against current design constraints.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration overhead. Consider the 12 ns speed and 84-pin PLCC form factor for existing board layouts. Evaluate power consumption requirements given the automatic power-down capabilities. Ensure voltage levels match the 5V TTL-compatible specification.
