7025S45GB/3215

Memory IC Overview

The Renesas Electronics Corporation 7025S45GB/3215 is a dual-port static random-access memory (SRAM) device belonging to the 7025 series. It features an 8K x 16 bit organization, providing a total storage capacity of 128 kilobits. The component operates asynchronously with a maximum access time of 45 nanoseconds. It utilizes a parallel interface and requires a single 5V power supply within a tolerance range of 4.5V to 5.5V. The device supports battery backup operation for data retention down to 2V. It is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. The operational temperature range extends from -40°C to +85°C.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes from two separate ports.
• Integrated on-chip hardware support for semaphore signaling to facilitate port arbitration and synchronization.
• Separate upper-byte and lower-byte control lines designed for compatibility with multiplexed bus systems.
• Automatic power-down functionality controlled by Chip Enable signals to minimize standby power consumption.

Memory IC Applications

• High-speed data buffering in communication systems requiring concurrent processor access.
• Master/slave configurations for expanding data bus widths to 32 bits or greater.
• Industrial control systems operating within extended temperature environments.
• Embedded applications necessitating low-power standby modes during idle periods.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS compliance status as specific suffixes may indicate non-compliant variants. Validate package integrity upon receipt, as surface-mount components are sensitive to mechanical stress. Ensure design-in documentation matches the exact 7025S45GB/3215 designation to avoid pinout mismatches with similar series members.

Memory IC Selection Notes

Select this component when asynchronous dual-port connectivity is required for shared memory resources. Consider the 45ns access speed against system timing requirements. Evaluate the 100-pin TQFP footprint for PCB layout constraints. Assess power management needs regarding automatic standby modes. Verify that the 5V logic levels align with interfacing microcontroller or processor I/O standards.
