BQ2203APN

Overview

The BQ2203APN is a nonvolatile SRAM controller manufactured by Benchmarq. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to 85°C. The component utilizes through-hole mounting and is housed in a 16-PDIP package.

Feature Summary

• Nonvolatile SRAM control functionality
• Through-hole mounting capability

Applications

• Industrial systems requiring nonvolatile memory management
• Commercial equipment with standard voltage requirements
• Embedded controllers needing SRAM retention

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm that the 16-PDIP through-hole package aligns with existing PCB layouts. Ensure compatibility with 4.5V to 5.5V power rails. Check for available replacement options due to potential end-of-life constraints.

Selection Notes

Select this part only if through-hole assembly is required for the design. Verify that the system environment remains within the specified -40°C to 85°C temperature limits. Confirm that the 4.5V to 5.5V supply voltage matches the board's power distribution network. Consider obsolescence when designing long-term production runs.

Part Context

This component belongs to the Benchmarq family of nonvolatile SRAM controllers. It is designed for applications requiring reliable memory state retention without external battery backup circuits. The device integrates control logic specifically tailored for SRAM interfaces in industrial and commercial environments.

Replacement Considerations

Public confirmed substitute part numbers are not available for this obsolete component. Evaluate pin-compatible alternatives or redesign the interface circuitry to accommodate modern nonvolatile memory solutions.
