7008L12JG8

Memory IC Overview

The Renesas Electronics Corporation 7008L12JG8 is a high-speed 64K x 8 dual-port static RAM providing a total storage capacity of 512Kb. It features asynchronous parallel interface operation with a maximum access time of 12 ns and write cycle time of 12 ns. The device operates on a single 5V power supply within the 4.5V to 5.5V range and supports an industrial temperature range from -40°C to +85°C. It is housed in an 84-pin PLCC package measuring 29.31x29.31 mm.

Memory IC Feature Summary

• Supports simultaneous independent reads and writes at both ports without conflict
• Includes on-chip hardware semaphore signaling for port arbitration
• Features automatic low-power standby mode controlled by chip enable inputs

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processors
• Data acquisition systems requiring concurrent host and peripheral access

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm RoHS3 compliance status and check for specific PCN documentation regarding assembly site changes or label modifications before finalizing procurement plans.

Memory IC Selection Notes

Select this model when 12 ns latency is required for dual-port applications. Ensure system design accommodates the 84-PLCC surface mount footprint. Verify that the 5V logic levels match the target system voltage requirements and confirm thermal management capabilities for the specified industrial temperature range.

Memory IC Part Context

This component belongs to the 7008 series of dual-port SRAMs, which also includes variants like the 7008L20JGI8 offering slower 20 ns speeds. The series provides flexible memory expansion options for 16-bit or wider bus architectures through master/slave configurations.
