7133LA25PFGI8

Overview

The 7133LA25PFGI8 is a dual-port static random access memory (SRAM) manufactured by Renesas Electronics. It provides a storage capacity of 32 kbit organized as 2K x 16 words. The device features an asynchronous parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 300 mA. The component supports single data rate (SDR) operation and is housed in a TQFP-100 surface-mount package. It is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous parallel interface supporting standard logic levels

Procurement Notes

Verify the specific suffix PFGI8 against official Renesas documentation to confirm package type, lead-free status, and humidity sensitivity level. Ensure compatibility with existing board designs regarding pinout and voltage requirements. Confirm availability through authorized distributors as production cycles may vary. Check for any recent product change notices affecting specifications or manufacturing sites.

Selection Notes

Select this component when a 32 kbit dual-port SRAM with 25 ns access speed is required. It is suitable for applications needing independent port access without arbitration overhead. Consider the TQFP-100 package for surface mount assembly. Verify that the 4.5 V to 5.5 V supply range matches the system power rails. Evaluate thermal management needs given the 300 mA maximum current draw.
