71V321L55PFI8

Memory IC Overview

The Renesas Electronics Corporation 71V321L55PFI8 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 operation with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 3 volts to 3.6 volts and supports surface mount installation in a 64-lead Thin Quad Flat Package (TQFP) measuring 14x14 millimeters. The component is rated for an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

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

Memory IC Applications

Data buffering in high-speed digital signal processing systems
Cache memory implementation in embedded controllers
FIFO buffer applications requiring independent port access

Memory IC Procurement Notes

Verify the specific suffix 'I8' against official manufacturer documentation to confirm package variant and lead finish specifications. Confirm RoHS compliance status, as historical data indicates potential non-compliance for this series. Validate current availability through authorized distributors, noting that this part number may be discontinued or subject to long lead times.

Memory IC Selection Notes

Select this component when independent dual-port access is required for 16-kilabit memory configurations. Ensure the design accommodates the 3V to 3.6V supply voltage requirements and the 64-TQFP footprint. Verify that the 55-nanosecond access speed meets the system timing constraints compared to faster alternatives like the 25ns variants.
