7143LA25J8

Overview

The Renesas Electronics Corporation 7143LA25J8 is a volatile static random-access memory (SRAM) integrated circuit. It features a parallel interface and a storage capacity of 32 kbit, organized as 2K x 16 bits. The device operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 68-LCC (J-Lead) package. Key electrical parameters include a write cycle time of 35ns and an operating temperature range from 0°C to 70°C.

Feature Summary

• Provides non-volatile data retention capabilities typical of SRAM technology for rapid data access.
• Supports parallel data transfer interfaces for system integration.
• Designed for surface-mount technology assembly on printed circuit boards.

Applications

• Embedded systems requiring fast temporary data storage
• Industrial control units with standard voltage requirements
• Consumer electronics utilizing parallel memory architectures

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels due to potential availability constraints. Confirm package integrity upon receipt, as moisture sensitivity level 3 requires proper handling. Check current lifecycle status, as this part may be subject to discontinuation notices. Ensure compatibility with existing board designs regarding the 68-LCC footprint and voltage specifications before procurement.

Selection Notes

Select this component when a 32 kbit parallel SRAM with a 68-pin LCC package is required. Ensure the application environment stays within the 0°C to 70°C temperature range. Verify that the system power supply remains stable between 4.5V and 5.5V. Consider the 35ns write cycle time against system timing requirements. Evaluate alternative packages if surface-mount constraints differ.
