M40Z300WMQ6E

Supervisors Overview

The M40Z300WMQ6E is a supervisor IC from STMicroelectronics designed for non-volatile RAM (NVRAM) protection. It supports up to eight low-power SRAMs and operates within a supply voltage range of 2.7 V to 3.6 V. The device features a single channel with an open-drain or open-collector output driver that is active low. It is housed in a 16-pin SOIC package measuring 10 x 4 x 1.6 mm. The component functions reliably across an operating temperature range of -40 °C to +85 °C.

Supervisors Feature Summary

• Provides dedicated supervision for non-volatile memory systems
• Supports monitoring of multiple low-power SRAM units simultaneously
• Features flexible open-drain or open-collector output configuration

Supervisors Applications

• Non-volatile RAM (NVRAM) power management
• Low-power SRAM array supervision
• Embedded system memory protection circuits

Supervisors Procurement Notes

Verify the specific suffix 'E' against official STMicroelectronics documentation to confirm exact electrical characteristics and compliance status. Ensure the 16-SOIC package dimensions match your PCB footprint requirements. Confirm that the active-low open-drain output aligns with your microcontroller input specifications before finalizing procurement.

Supervisors Selection Notes

Select this component when designing systems requiring centralized supervision for multiple low-power SRAMs. It is suitable for applications needing a single-channel supervisor with flexible output drive options. Consider the 2.7 V to 3.6 V operating range to ensure compatibility with your system's power rails and environmental temperature constraints.

Supervisors Part Context

This part belongs to STMicroelectronics' Zeropower SRAM Supervisor family, which specializes in protecting non-volatile memory during power transitions. These supervisors are engineered to manage write-enable signals and reset lines for low-power static RAM arrays, ensuring data integrity in embedded environments.

Supervisors Replacement Considerations

Consult official STMicroelectronics substitution guides for verified alternatives. Generic equivalents may not support the specific multi-SRAM architecture or voltage ranges required for this application.
