7133LA15JI

Overview

The Renesas Electronics Corporation 7133LA15JI is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 32 kilobits organized as 2K words by 16 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 15 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package. The component supports surface-mount installation.

Feature Summary

• Dual-port architecture enabling independent simultaneous access for two processors
• Asynchronous operation without requiring a system clock signal
• Parallel data interface for direct connection to microprocessors

Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded controllers
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify the current manufacturing status, as this part number has been identified as obsolete or end-of-life in multiple distributor records. Confirm availability through authorized channels or approved substitute components. Ensure compliance with RoHS directives if required by the target application environment. Check for moisture sensitivity level handling requirements during storage and assembly.

Selection Notes

Select this component when a dual-port SRAM with 15ns access speed is required in a PLCC-68 package. Compare against the 7133SA series for industrial temperature ranges or the 7133LA series for commercial variants. Verify that the 2Kx16 organization matches the system address and data bus width requirements.

Part Context

This device belongs to the Renesas 7133SA/LA family of high-speed dual-port SRAMs. These components are designed for applications requiring independent read/write ports. The 'LA' suffix typically denotes commercial temperature specifications, while 'SA' indicates extended industrial ranges. The family shares pinouts but varies in speed grades and environmental ratings.

Replacement Considerations

Publicly confirmed substitutes include the IDT7133LA15JI and other variants within the 7133LA series with compatible speed grades and packaging.
