70121L45JG8

Memory IC Overview

The 70121L45JG8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 18Kbits, organized as 2K words by 9 bits. The device features asynchronous parallel access with a maximum access time of 45 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in an 84-PLCC package variant, specifically the 52-LCC (J-Lead) configuration measuring 19.13x19.13 mm. The component functions reliably across an operating temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous interface supporting flexible timing requirements without clock synchronization
• Parallel data bus organization for direct microprocessor or controller interfacing

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded control systems
• Data storage in industrial automation controllers

Memory IC Procurement Notes

Verify current availability status as this component may be discontinued or subject to end-of-life notices. Confirm package dimensions and pinout compatibility during integration planning. Check RoHS compliance documentation for regulatory adherence. Ensure supply chain stability due to potential obsolescence risks associated with legacy SRAM products.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Consider the 45ns access speed for moderate-performance applications. Verify voltage tolerance matches system power rails. Evaluate package constraints against PCB layout limitations. Assess thermal performance within the specified commercial temperature range.

Memory IC Part Context

This part belongs to the Renesas 70121 series of dual-port SRAMs. It shares architectural similarities with other members like the 7008L and 7025S families but differs in density and speed specifications. The series targets applications requiring independent port access for data sharing between processors or peripherals.
