7142LA25JGI8

Overview

The Renesas 7142LA25JGI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits, organized as 2048 words by 8 bits. The device features asynchronous parallel interfaces for both ports, allowing independent read and write operations. It supports a supply voltage range from 4.5 volts to 5.5 volts. The component operates within an industrial temperature range of -40°C to +85°C. It utilizes a 52-lead Plastic Leadless Chip Carrier (PLCC) package with J-leads.

Feature Summary

• Dual-port architecture enabling simultaneous independent access by two masters
• Asynchronous operation without requiring a common clock signal
• CMOS technology ensuring low power consumption during standby and active states

Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded microcontroller architectures
• Interfacing between disparate data rates in communication protocols

Procurement Notes

Verify the exact suffix designation against official Renesas documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the supplier provides valid traceability documents for this specific part number variant.

Selection Notes

Select this component when independent dual-port access is required for shared memory resources. The asynchronous interface simplifies timing constraints compared to synchronous alternatives. Verify that the 52-PLCC package fits the target PCB footprint and that the voltage levels match the system logic requirements.
