7025L20G

Memory IC Overview

The Renesas Electronics Corporation 7025L20G is a dual-port static random-access memory (SRAM) device with a storage capacity of 128 kbit, organized as 8k x 16. It features an asynchronous parallel interface and a typical access time of 20 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole installation in a PGA-84 package. It is designed for single-port or master/slave configurations in systems requiring 32-bit or wider data buses.

Memory IC Feature Summary

• Supports simultaneous independent reads from both ports without conflict
• Includes on-chip hardware semaphore signaling for port arbitration
• Features automatic power-down mode controlled by chip enable signals

Memory IC Applications

• Stand-alone 128K-bit dual-port memory systems
• Master/slave dual-port RAM combinations for 32-bit or wider word systems
• Battery backup operations requiring 2V data retention

Memory IC Procurement Notes

Verify the specific suffix 'G' against official datasheets to confirm RoHS compliance status, as legacy variants may differ. Confirm package type PGA-84 matches design requirements. Check current lifecycle status as discontinuation notices exist for related 7025 series parts. Validate operating temperature range specifications before integration into final assemblies.

Memory IC Selection Notes

Select this component when 20 ns access speed and 128 kbit capacity are required for dual-port applications. Ensure the system supports 5V TTL-compatible logic levels. Verify that the PGA-84 through-hole package fits the PCB layout constraints. Consider alternative speeds like 15 ns or 25 ns if timing margins require adjustment.

Memory IC Part Context

The 7025L20G belongs to the Renesas 7025 family of high-speed dual-port SRAMs. This family provides true dual-ported memory cells allowing simultaneous access. Variants differ primarily in access speed and package type, including PGA, PLCC, TQFP, and flatpack options. The L-series typically denotes industrial temperature ranges compared to commercial S-series parts.
