7025L25PFG8

Memory IC Overview

The Renesas Electronics Corporation 7025L25PFG8 is a high-speed asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 128 kbit. The device features an 8K x 16 organization and supports parallel interface communication. It operates within a supply voltage range of 4.5 V to 5.5 V and provides an access time of 25 ns. Designed for surface-mount applications, the component is housed in a 100-pin TQFP package. It functions reliably across an industrial temperature range from 0°C to +70°C.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent read/write operations by two separate processors
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity
• Separate upper-byte and lower-byte control lines allowing compatibility with multiplexed bus systems
• Automatic power-down feature controlled by Chip Enable signals to minimize standby power consumption

Memory IC Applications

• Stand-alone 128K-bit dual-port memory modules
• Master/Slave dual-port RAM configurations for 32-bit or wider word systems
• High-speed data buffering between asynchronous processing units
• Industrial control systems requiring reliable concurrent data access

Memory IC Procurement Notes

Verify the specific suffix PFG8 against official Renesas documentation to confirm the 100-TQFP surface-mount package and lead-free status. Confirm that the 25 ns speed grade matches system timing requirements. Check current lifecycle status as components may be subject to discontinuation notices. Ensure humidity sensitivity level (MSL 3) handling procedures are followed during assembly.

Memory IC Selection Notes

Select this component when a 128 kbit dual-port SRAM with 25 ns access time is required for 5V TTL-compatible systems. The 100-TQFP package suits surface-mount designs needing moderate pin density. Consider alternative speeds like 15 ns or 35 ns if performance constraints differ. Verify that the 0°C to +70°C operating range meets environmental specifications compared to extended temperature variants.

Memory IC Part Context

The 7025 series represents a family of high-speed dual-port SRAMs designed for versatile memory applications. This specific model belongs to the L-series, indicating low-power characteristics relative to older S-series counterparts. The device integrates advanced arbitration logic to facilitate seamless data sharing between multiple masters without external controller intervention.

Memory IC Replacement Considerations

The IDT7025S35PF8 is documented as a discontinued upgrade path replacement. Verify functional equivalence regarding pinout and electrical parameters before substitution.
