71421LA55PF8

Memory IC Overview

The Renesas Electronics Corporation 71421LA55PF8 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 utilizes an asynchronous parallel interface with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and is housed in a 64-lead Thin Quad Flat Package (TQFP) measuring 14x14 millimeters. The component supports surface-mount installation and functions within an ambient temperature range of 0°C to 70°C.

Memory IC Feature Summary

Dual-port architecture enabling independent simultaneous read/write operations on separate ports
Asynchronous parallel interface for flexible system integration
Volatile memory technology retaining data only during active power supply

Memory IC Applications

Data buffering in high-speed digital signal processing systems
Cache memory implementation in embedded microcontroller architectures
FIFO buffer applications in telecommunications equipment

Memory IC Procurement Notes

Verify the specific suffix 'PF8' against official manufacturer documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status, as older variants may not meet current environmental directives. Validate that the 55ns speed grade matches system timing requirements before procurement.

Memory IC Selection Notes

Select this component when a 16Kb dual-port SRAM with a 55ns access time is required in a 64-pin TQFP package. Ensure the design accommodates the 4.5V to 5.5V operating voltage range. Consider the commercial temperature range limits if operation outside 0°C to 70°C is necessary.

Memory IC Part Context

This part belongs to the Renesas 71321/71421 series of dual-port SRAMs. These devices are designed for applications requiring independent port access. The 'LA' designation typically indicates a lead-free or specific material variant within the product line, while 'PF8' denotes the 64-TQFP package with reel packaging.
