X5168S8Z-2.7A

Supervisors Overview

The X5168S8Z-2.7A is a CPU supervisor integrated circuit manufactured by Intersil, now part of Renesas Electronics. It combines a voltage monitoring function with a 16Kbit serial peripheral interface (SPI) electrically erasable programmable read-only memory (EEPROM). The device operates within a supply voltage range of 2.7V to 5.5V and features an active-low reset output. It is housed in an 8-pin small outline integrated circuit (SOIC) package.

Supervisors Feature Summary

• Integrates a microprocessor supervisory circuit with a watchdog timer and power-fail detection capability.
• Includes non-volatile 16Kbit SPI EEPROM for storing configuration data or user information.
• Provides automatic system reset upon detection of undervoltage conditions.

Supervisors Applications

• Embedded systems requiring reliable power management and data retention.
• Industrial control units utilizing SPI-based configuration storage.
• Consumer electronics with low-power supervision requirements.

Supervisors Procurement Notes

Verify the manufacturer designation, as Intersil products are now managed under the Renesas Electronics portfolio. Confirm that the specific suffix indicates the standard SOIC-8 package without additional temperature or tape-and-reel variations unless explicitly documented. Ensure compatibility with existing PCB footprints and SPI communication protocols during integration.

Supervisors Selection Notes

Select this component when a combined supervisor and non-volatile memory solution is required in a compact form factor. The 16Kbit capacity suits applications needing moderate data storage alongside system monitoring. Verify that the active-low reset polarity matches the target microcontroller's input requirements.

Supervisors Part Context

This part belongs to the X5168 series of CPU supervisors featuring embedded EEPROM. It serves as a consolidated solution for system reliability, replacing separate voltage monitor and memory chips. The series is designed for cost-sensitive applications requiring robust power management and persistent data storage in industrial and consumer environments.

Supervisors Replacement Considerations

Consult official Renesas documentation for cross-reference lists. Direct substitutes may include other parts from the X5168 family with compatible pinouts and memory sizes. Verify electrical specifications and package dimensions before substitution.
