7140SA70JI8

Memory IC Overview

The 7140SA70JI8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 8 kilobits organized as 1K words by 8 bits. The device features parallel interface access with a maximum access time of 70 nanoseconds and a write cycle time of 70 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range from -40°C to +85°C. The component is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package measuring 19.13mm x 19.13mm.

Memory IC Feature Summary

Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Memory IC Applications

High-speed data buffering in telecommunications equipment.

Memory IC Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or approved obsolescence notices. Compliance with RoHS standards is not confirmed for this specific part number, requiring careful assessment for regulated environments.

Memory IC Selection Notes

Engineers should evaluate the 70ns access speed against system timing requirements. The 52-PLCC surface-mount package necessitates compatible PCB footprint design. Alternative components within the same family may offer different access speeds or pin configurations while maintaining functional compatibility.

Memory IC Part Context

The 7140SA series belongs to Renesas' legacy portfolio of CMOS dual-port SRAMs. These devices were designed for applications requiring high-bandwidth data transfer between processors or peripherals. The 7140SA70JI8 specifically denotes the 70ns speed grade within the 8Kb capacity segment of this product line.
