7143LA25J

Overview

The 7143LA25J is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features asynchronous parallel interface with a maximum access time of 25 nanoseconds and a write cycle time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial temperature range from 0°C to 70°C. The component is housed in a 68-lead Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

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

Applications

• High-speed data buffering in communication systems
• Cache memory for microprocessor-based applications
• Real-time data acquisition systems

Procurement Notes

Verify the specific suffix J against official Renesas documentation to confirm package type and lead finish. Confirm RoHS compliance status as historical data may vary. Check for End-of-Life notices or Last Time Buy notifications directly from the manufacturer before procurement planning.

Selection Notes

Select this component when dual-port functionality is required for concurrent host and peripheral access. Ensure the system design accommodates the 68-PLCC surface mount footprint. Verify that the 25ns speed meets the timing requirements of the target application bus.

Part Context

This part belongs to the 7143SA/LA series of high-performance dual-port SRAMs. It shares architectural similarities with other members like the 7143LA20JG8 but differs in speed grade and package configuration. The LA suffix typically denotes industrial temperature rating compared to SA variants.

Replacement Considerations

IDT7143LA25J is a verified equivalent part number under the Integrated Device Technology brand, which was acquired by Renesas.
