X5328S8

Supervisors Overview

The X5328S8 is a single-channel supervisor IC combining power-on reset control, supply voltage supervision, and block lock protect serial EEPROM memory in one package. It features an open-drain or open-collector output for the supervisor function. The device integrates a 32Kbit SPI EEPROM with hardware write protection capabilities to prevent unauthorized data modification. It operates within a standard SOIC-8 plastic package.

Supervisors Feature Summary

• Integrates CPU supervisor functions including power-on reset and supply voltage monitoring into a single component
• Includes 32Kbit SPI EEPROM with block lock protection to secure stored data against unauthorized access
• Provides open-drain or open-collector supervisor output compatible with various logic families

Supervisors Applications

• High-speed data transmission systems requiring reliable power sequencing
• Embedded controllers needing integrated non-volatile storage and supervision
• Industrial equipment requiring protected configuration memory

Supervisors Procurement Notes

Verify the specific suffix designation as the base part number may correspond to multiple voltage variants or packaging options. Confirm the manufacturer status, as Intersil operations have transitioned to Renesas Electronics America. Ensure the selected variant matches the required operating voltage range and package type before ordering.

Supervisors Selection Notes

Select this component when system design requires both voltage supervision and protected non-volatile memory storage. Consider the open-drain output capability for level shifting requirements. Verify that the SPI interface speed meets the system's communication needs. Check for obsolete status indicators as availability may be limited compared to newer generations.

Supervisors Part Context

This device belongs to the X5328 series of combined supervisor and EEPROM ICs. It serves as a consolidated solution for microcontroller-based systems, reducing board space by integrating three distinct functions: reset generation, voltage monitoring, and protected data storage. The series is designed for applications where reliability and data integrity are critical.

Supervisors Replacement Considerations

Direct substitutes include the X5325S8Z which offers similar functionality. Verify pin compatibility and electrical specifications before substitution. Note that the X5328S8 is listed as obsolete by some distributors; check current lifecycle status with Renesas Electronics America for long-term supply assurance.
