7025L20PFGI8

Memory IC Overview

The Renesas Electronics Corporation 7025L20PFGI8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kilobits organized as 8K words by 16 bits per word. The device features independent read/write ports allowing simultaneous access to the same memory location without conflict. It operates within a supply voltage range of 4.5V to 5.5V and supports an access time of 20 nanoseconds. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. It is designed for industrial temperature ranges spanning from -40°C to +85°C ambient temperature.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes from either port.
• On-chip hardware support for semaphore signaling and automatic port arbitration logic to manage bus conflicts.
• Separate upper-byte and lower-byte control lines facilitating compatibility with multiplexed data buses.
• Automatic power-down mode controlled by Chip Enable signals to minimize standby power consumption.

Memory IC Applications

• Stand-alone 128K-bit dual-port memory systems
• Master/Slave dual-port RAM configurations for 32-bit or wider data bus architectures
• High-speed data buffering between asynchronous processors

Memory IC Procurement Notes

Verify the specific suffix 'GI8' against official Renesas documentation to confirm package type, lead finish, and environmental compliance status such as RoHS3. Confirm that the 100-TQFP variant matches the required footprint and pin pitch for the target PCB design. Check current production status as this part number may be subject to discontinuation notices or lifecycle changes.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required without external arbitration logic. The 20ns access speed suits applications needing moderate-to-high throughput. Ensure the system operates within the specified 4.5V to 5.5V voltage range and requires the industrial temperature grade (-40°C to +85°C). Consider the 100-pin TQFP package constraints for board space and thermal management.

Memory IC Part Context

The 7025 series represents a family of high-speed dual-port SRAMs from Renesas Electronics. These devices are engineered for applications requiring concurrent data access from multiple masters. The 7025L20PFGI8 belongs to the L-series, indicating specific performance and packaging characteristics within this broader product line, distinct from older S-series variants.

Memory IC Replacement Considerations

Official upgrade alternatives include the 7025L20PFGI and 7025L20JGI8. Verify pinout compatibility and electrical parameter equivalence before substitution. Note that package differences exist between TQFP and PLCC variants within the replacement options.
