71V321L35J8

Overview

The Renesas Electronics Corporation 71V321L35J8 is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 16 kilobits organized as 2K by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 3 volts to 3.6 volts and has a maximum power supply current of 130 milliamperes. The component is housed in a 52-pin Plastic Leadless Chip Carrier (PLCC) package measuring 19.13 by 19.13 millimeters. It supports surface mount installation and functions reliably across an operating temperature range of 0 degrees Celsius to 70 degrees Celsius.

Feature Summary

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

Applications

• Data logging systems requiring high-speed temporary storage.

Procurement Notes

Verify the specific suffix J8 against official datasheets to confirm the 52-PLCC package configuration and commercial temperature range. Confirm RoHS compliance status, as documentation indicates non-compliance for this specific part number. Check for Product Change Notifications regarding lead-free transitions or labeling updates before procurement.

Selection Notes

Select this component when a dual-port SRAM solution is required for applications needing independent port access. Ensure the design accommodates the 52-PLCC footprint and 3.3-volt logic levels. Verify that the 35-nanosecond access speed meets system timing requirements and that the commercial temperature range aligns with environmental conditions.
