7143LA20J8

Overview

The Renesas 7143LA20J8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features asynchronous parallel interfaces for independent read and write operations. Key electrical specifications include a maximum access time of 20 nanoseconds and a supply voltage range of 4.5 volts to 5.5 volts. Maximum supply current is rated at 280 mA. The component operates within an ambient temperature range of 0°C to +70°C and is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) surface-mount package.

Feature Summary

• Supports simultaneous independent read and write operations through separate port architectures
• Provides high-speed data transfer with a 20 nanosecond access time specification
• Utilizes standard parallel interface logic compatible with common microprocessor systems

Applications

• High-performance embedded system memory buffers
• Data acquisition system temporary storage
• Network equipment packet buffering applications

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status as legacy variants may differ from current production standards. Validate that the 68-lead PLCC package dimensions match the target printed circuit board layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when dual-port functionality is required to allow concurrent host and peripheral access without arbitration delays. Ensure the design supports the specified 4.5V to 5.5V power supply rails. Verify that the 280mA maximum current consumption fits within the thermal management capabilities of the enclosure and PCB copper area.
