X5163S8ZT1

Supervisors Overview

The X5163S8ZT1 is a supervisory circuit manufactured by Renesas Electronics Corporation, designed for CPU protection and data retention. It integrates four primary functions: Power-on Reset Control, Watchdog Timer, Supply Voltage Supervision, and Block Lock Protect Serial EEPROM with a capacity of 16Kbit. The device operates within a supply voltage range of 2.7V to 3.6V and utilizes an SPI interface for communication with the embedded memory. It is housed in an 8-pin SOIC package and supports low-voltage reset operations.

Supervisors Feature Summary

• Integrates CPU supervisor functions including power-on reset, watchdog timer, and supply voltage monitoring into a single chip.
• Includes non-volatile 16Kbit serial EEPROM with hardware block lock protection to prevent unauthorized data modification.
• Supports standard SPI serial interface for reliable data access and configuration.

Supervisors Applications

• Microcontroller system supervision
• Embedded data storage applications
• Industrial control systems

Supervisors Procurement Notes

Verify the specific suffix ZT1 against official Renesas documentation to confirm tape-and-reel packaging and exact electrical characteristics. Confirm RoHS compliance status as product lines may undergo environmental regulation updates. Ensure the source provides valid traceability for this obsolete or legacy component series.

Supervisors Selection Notes

Select this component when a combined solution for system reset management and secure data storage is required. It is suitable for designs needing hardware-enforced EEPROM protection without external security chips. Verify that the SPI interface compatibility matches the host microcontroller.

Supervisors Part Context

This part belongs to the X5163 family of CPU supervisors from Renesas (formerly Intersil). These devices are engineered to replace discrete supervisor and EEPROM components, reducing board space and design complexity while ensuring system reliability through integrated hardware protections.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the X5163 series with different voltage thresholds or package options. Verify if newer generations from Renesas offer equivalent functionality with updated manufacturing processes.
