7006L20JI

Overview

The Renesas Electronics Corporation 7006L20JI is a high-speed 16K x 8 Dual-Port Static RAM with a total storage capacity of 128 kbit. It features asynchronous parallel interface operation and supports simultaneous reads from both ports. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption of 320 mA. It offers a 20 ns access time and functions reliably across an industrial temperature range of -40°C to +85°C. The component is housed in a PLCC-68 surface-mount package.

Feature Summary

• True dual-ported memory cells enabling simultaneous independent access to the same memory location by two separate processors.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between ports.
• Automatic power-down feature controlled by chip enable signals to minimize standby power consumption.

Applications

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

Procurement Notes

Verify the specific suffix JGI against official datasheets to confirm pinout compatibility and RoHS status. Confirm lead availability through authorized distributors as stock levels fluctuate. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification. Cross-reference part numbers with IDT aliases if sourcing from legacy inventories.

Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration circuitry. The 5V TTL-compatible interface simplifies integration with standard logic families. Consider the PLCC-68 package constraints for PCB layout density. Verify that the 20 ns access speed meets the timing requirements of the target system architecture.

Part Context

This part belongs to the 7006L series of dual-port SRAMs manufactured by Renesas Electronics. It is functionally equivalent to the IDT7006L20JGI variant. The series is designed for high-performance embedded applications requiring fast, conflict-free memory sharing between multiple masters.

Replacement Considerations

IDT7006L20JGI is a confirmed substitute part number with identical specifications and pinout compatibility.
