X5165S8IZ-2.7A

Supervisors Overview

The X5165S8IZ-2.7A is a CPU supervisory circuit manufactured by Renesas Electronics Corporation, integrating a 16Kbit SPI EEPROM with watchdog timer and voltage monitoring functions. It operates within a supply voltage range of 2.7V to 5.5V and features a high-active reset output with a typical delay of 300ms. The device supports industrial temperature ranges and utilizes an 8-pin SOIC surface-mount package for compact system integration.

Supervisors Feature Summary

• Integrates non-volatile memory with supervisory logic
• Provides automatic power-fail detection and reset generation
• Includes programmable watchdog timer functionality

Supervisors Applications

• Microcontroller system protection
• Embedded storage data retention
• Industrial control board supervision

Supervisors Procurement Notes

Verify the specific suffix 'IZ' against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status as manufacturing processes evolve. Check current lifecycle status directly with Renesas or authorized distributors, as availability may vary by region.

Supervisors Selection Notes

Select this component when simultaneous voltage supervision and persistent data storage are required in a single package. Ensure the 2.7V threshold aligns with the target microcontroller's operating voltage. Verify that the SPI interface compatibility matches the host processor's communication protocol requirements.

Supervisors Part Context

This part belongs to the X5165 series of combined supervisor and EEPROM devices from Renesas. It succeeds earlier Intersil designs following corporate acquisitions. The series provides integrated solutions for systems requiring both reliable reset management and configuration data storage without external components.

Supervisors Replacement Considerations

Consult official substitution lists for equivalents such as X5165S8Z variants. Verify pinout and electrical parameter compatibility before replacing. Cross-reference specific suffix codes for package and temperature differences.
