Memory IC datasheet and documents for 71421LA4J

71421LA4J

Memory IC Overview

The Renesas Electronics Corporation 71421LA4J is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device features asynchronous parallel interface with an access time of 4 nanoseconds. It operates on a single 5-volt power supply within the range of 4.5 to 5.5 volts. The component is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation.

Memory IC Feature Summary

Supports simultaneous independent read and write operations at two distinct ports
Provides high-speed data transfer via asynchronous parallel interface
Maintains data integrity through volatile static RAM technology

Memory IC Applications

High-performance embedded systems requiring fast local memory
Network infrastructure equipment and communication devices
Industrial automation controllers and programmable logic applications

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as historical records indicate non-compliance for this specific variant. Confirm package authenticity against the 52-PLCC specification. Check for moisture sensitivity level requirements during handling. Ensure voltage specifications match system design constraints. Validate manufacturer documentation for current lifecycle status.

Memory IC Selection Notes

Select this component when ultra-fast 4-nanosecond access is critical for system timing. Choose the PLCC package if existing board layouts require this specific footprint. Consider the 16-kilobit density for small buffer or cache applications. Verify that the single 5-volt supply aligns with the target platform's power architecture.

Memory IC Part Context
