BQ2202PN-N

Overview

The BQ2202PN-N is a nonvolatile SRAM controller and voltage supervisor IC manufactured by Benchmarq. It integrates memory control functions with reset supervision in a single package. The device operates within an industrial temperature range of -40°C to 85°C. It monitors one voltage channel to ensure system stability. The component is housed in a 16-pin Dual In-Line Package (PDIP) with a standard pin spacing of 0.300 inches (7.62mm). This configuration supports through-hole mounting for robust circuit board integration.

Feature Summary

• Integrates nonvolatile SRAM memory controller functionality with voltage supervision
• Provides single-channel voltage monitoring for system reset generation
• Designed for industrial temperature operation ranges
• Utilizes a 16-pin PDIP package for reliable through-hole mounting

Applications

• Nonvolatile SRAM data retention management
• Voltage supervisor circuits requiring reset signals
• Industrial electronic systems operating in extreme temperatures
• Embedded memory control interfaces

Procurement Notes

Verify the manufacturer designation carefully, as sources list both Benchmarq and Texas Instruments for this part number. Confirm the exact suffix 'N' corresponds to the specific package and temperature rating required. Ensure the component matches the 16-PDIP form factor. Cross-reference the datasheet to confirm the single-channel supervision capability aligns with your design specifications before procurement.

Selection Notes

Select this component when a combined solution for SRAM control and voltage supervision is required. The 16-PDIP package is suitable for prototyping or applications where through-hole mounting is preferred over surface mount technology. Consider the -40°C to 85°C operating range if the environment exceeds commercial limits. Verify compatibility with the target SRAM interface requirements.

Part Context

This part belongs to the BQ2202 family of controllers. It serves as a specialized integrated circuit combining memory management and power supervision. The designation indicates a specific variant within the Benchmarq product line, focusing on nonvolatile memory support. It addresses the need for compact solutions that handle both data integrity and power monitoring functions simultaneously.
