Overview
The 71V321L25PF8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 16 kbit organized as 2K x 8 bits. The device operates with an asynchronous parallel interface and supports a supply voltage range from 3 V to 3.6 V. Access time is specified at 25 ns, with a maximum power supply current of 100 mA. It functions within an operating temperature range of 0°C to +70°C and is housed in a 64-TQFP surface-mount package.
Feature Summary
- Dual-port architecture enabling independent access to the same memory array
- Asynchronous operation for flexible system integration
- Single 3.3 V power supply compatibility
Applications
- Data buffering in high-speed digital systems
- Cache memory implementation in embedded controllers
- FIFO buffer applications requiring simultaneous read/write operations
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to soldering. Ensure packaging integrity matches reel specifications to prevent damage during surface mount assembly processes.
Selection Notes
Select this component when independent port access is required for concurrent data handling. Compare against single-port alternatives if simultaneous access is unnecessary. Verify voltage tolerance aligns with the 3 V to 3.6 V operational window and ensure thermal management suits the 0°C to +70°C industrial range.
Part Context
This part belongs to the 71V321L series of dual-port SRAMs. It serves as a successor to older variants like the 71V321S25PF8, offering updated manufacturing standards while maintaining similar electrical characteristics. The series provides reliable non-volatile-free storage solutions for industrial and commercial electronics.
Replacement Considerations
The 71V321L25PFG8 is listed as an upgrade replacement for discontinued versions such as the 71V321S25PF8. Verify pinout compatibility and package dimensions before substitution.
