7025L20JGI

Memory IC Overview

The Renesas Electronics Corporation 7025L20JGI is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 128 kbit. It features an 8K x 16 organization and a parallel interface. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum access time of 20 ns. It is housed in an 84-pin PLCC package and is designed for surface-mount installation. The component supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported memory cells enabling simultaneous independent reads and writes from either port without conflict.
• Integrated on-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity.
• Separate upper-byte and lower-byte control lines facilitate compatibility with multiplexed bus architectures.
• Automatic power-down feature controlled by Chip Enable signals allows entry into low standby power mode.

Memory IC Applications

• Stand-alone 128K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 32-bit or wider word systems
• Battery-backed memory applications requiring 2V data retention

Memory IC Procurement Notes

Verify the specific suffix JGI against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status as it may vary by manufacturing date. Check for End-of-Life notifications or discontinuation notices prior to finalizing procurement plans. Ensure moisture sensitivity level handling procedures are followed during assembly.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required. Verify that the 5V TTL-compatible logic levels match the system design. Ensure the 84-pin PLCC footprint fits the PCB layout constraints. Consider the 20 ns access time against system timing requirements.

Memory IC Part Context

The 7025 series represents a family of high-speed dual-port SRAMs designed for applications requiring fast, non-blocking memory access. This specific model utilizes asynchronous operation from either port, making it suitable for complex digital signal processing and communication interfaces where data throughput and latency are critical factors.

Memory IC Replacement Considerations

Cross-reference with IDT7025L20JGI as a potential equivalent part number. Verify pinout compatibility and electrical specifications before substitution. Check for any package or environmental certification differences between original and substitute sources.
