85105AGILF

Overview

The Renesas 85105AGILF is a high-performance, low-power SRAM memory device designed for demanding embedded applications. It features a capacity of 2 Megabits organized as 256K words by 8 bits. The component operates with a single 3.3V power supply and supports fast access times to ensure efficient data retrieval. It utilizes a standard parallel interface compatible with common microprocessor buses. The device is housed in a lead-free plastic package, adhering to environmental standards while maintaining reliable electrical performance for industrial and commercial use cases.

Feature Summary

• 2M-bit (256K x 8) static RAM configuration
• Single 3.3V VCC operation
• High-speed access time suitable for processor cache or buffer applications
• Lead-free package compliant with RoHS directives

Applications

• Embedded systems requiring non-volatile-like persistence without battery backup
• Industrial control units needing fast data logging
• Consumer electronics with limited power budgets
• Automotive infotainment systems requiring reliable temporary storage

Procurement Notes

Verify the specific suffix 'GILF' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure that the voltage levels of the host system match the 3.3V requirement strictly. Check for any updated revision notes regarding timing parameters before finalizing the design integration.

Selection Notes

Select this component when a small, fast SRAM is needed for code execution or data buffering in space-constrained designs. Compare access speeds against other Renesas SRAM families to ensure the timing meets the system clock requirements. Consider the package type availability for PCB layout constraints and thermal management needs during the selection phase.

Part Context

This part belongs to Renesas' broader portfolio of static random-access memories. It serves as a specialized solution for applications where speed and low power consumption are critical. The '85105' series typically denotes specific density and interface characteristics within the company's legacy and current product lines, often used in conjunction with microcontrollers.

Replacement Considerations

Check for direct cross-reference part numbers from Renesas or other manufacturers offering identical 256Kx8 3.3V SRAM specifications. Verify pin-to-pin compatibility if substituting with parts from different vendors. Ensure that the replacement maintains the same access time and power consumption profiles to avoid redesigning the surrounding circuitry.
