7025L20PFGI

Memory IC Overview

The Renesas Electronics Corporation 7025L20PFGI is an asynchronous dual-port static random access memory (SRAM) device. It features a storage capacity of 128 kbit organized as 8k x 16 bits. The component supports parallel interface operations with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 240 mA. The device is designed for surface mount installation in a TQFP-100 package. It functions reliably across an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation without requiring a system clock signal
• Single 5V power supply compatibility for simplified circuit design

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network infrastructure devices

Memory IC Procurement Notes

Verify the specific suffix PFGI to confirm the TQFP-100 surface-mount package and lead-free compliance status. Confirm RoHS directive adherence requirements against project specifications. Check humidity sensitivity level (MSL 3) handling protocols during assembly. Ensure the 4.5V to 5.5V voltage range matches the target system power rails. Validate that the 20 ns access time meets the timing constraints of the host processor interface.

Memory IC Selection Notes

Select this component when a 128 kbit dual-port SRAM with 20 ns speed is required. It is suitable for designs needing independent read/write ports on the same memory block. Choose this part over single-port variants if concurrent processor access is necessary. Consider the TQFP-100 footprint availability in the PCB layout phase. Verify that the 5V logic levels align with the connected system components.

Memory IC Part Context

This device belongs to the 7025L series of low-power dual-port SRAMs manufactured by Renesas Electronics. The series provides non-volatile-like performance with volatile memory density. The 7025L20 variant specifically targets applications requiring moderate speed and standard 5V operation. It serves as a replacement for older generations like the 7025S series in modern designs.

Memory IC Replacement Considerations

The 7025S15PFI is listed as a similar alternative, though it has a faster 15 ns access time and is discontinued. The 7025S45PFI is another discontinued option with slower 45 ns performance. Verify pinout compatibility and electrical characteristics before substituting these legacy parts.
