70825L35PFGI

Memory IC Overview

The 70825L35PFGI is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 128 kilobits, organized as 8K words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in an 80-pin Thin Quad Flat Package (TQFP). The component is designed for industrial temperature ranges extending from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array by two distinct controllers.
• Asynchronous operation allowing flexible timing integration without requiring a system clock signal.
• Parallel data interface supporting standard 16-bit word width for high-throughput data transfer.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation control units

Memory IC Procurement Notes

Verify the specific suffix PFGI against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as historical records indicate variations. Check current production status, as similar models in this series have been marked obsolete or discontinued in recent distributor listings. Ensure lead-free specifications match project requirements before ordering.

Memory IC Selection Notes

Select this component when a non-volatile-like speed with true dual-port independence is required at 5V logic levels. Compare against the 70V07L35 series if 3.3V operation is mandatory, noting the voltage difference. Consider the 70825L20 variant if faster 20ns access times are needed and the pinout remains compatible. Verify that the 80-TQFP footprint fits the available board space constraints.

Memory IC Part Context

This part belongs to the IDT 70825 family of dual-port SRAMs, now under the Renesas Electronics portfolio following corporate acquisitions. The family is characterized by high-density 128Kb configurations suitable for complex embedded applications. The 70825 series typically competes in markets requiring reliable, fast, and electrically isolated memory access between different processor domains.

Memory IC Replacement Considerations

Official substitutes include the IDT70825L20PFI for faster performance and the 70V07L35PFGI for lower voltage operation. Verify pin compatibility and electrical characteristics before substitution. Note that some variants may be obsolete; check current availability and lifecycle status.
