7025S45PFI

Memory IC Overview

The Renesas 7025S45PFI is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kbit, organized as 8k x 16 words. The device features a parallel interface with a maximum access time of 45 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an industrial temperature range from -40°C to +85°C. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processors
