M40Z300WMQ6F

Supervisors Overview

The M40Z300WMQ6F is a supervisory integrated circuit designed for non-volatile SRAM applications. It operates within a supply voltage range of 3.0 V to 3.6 V and features a threshold voltage of 2.6 V. The device supports up to eight low-power SRAMs, converting them into NVRAMs via an integrated battery backup switch. It provides one monitored input with an active low, open drain output. The component is housed in a 16-SOIC package and functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a battery backup switch to maintain data integrity in low-power SRAMs
• Provides active low open-drain reset signaling for system supervision
• Supports conversion of multiple low-power SRAMs into non-volatile memory configurations

Supervisors Applications

• Non-volatile SRAM supervisor circuits
• Battery backup systems for memory retention
• Low power SRAM protection interfaces

Supervisors Procurement Notes

Verify the specific suffix 'MQ6F' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure the operating voltage requirements align with the 3.0 V to 3.6 V specification. Confirm that the open-drain output type matches the target system's logic interface requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when designing systems requiring supervision for up to eight low-power SRAMs. It is suitable for applications needing a dedicated battery backup switch integrated with voltage monitoring. Consider the 16-SOIC package constraints and the specific 2.6 V threshold voltage relative to the system's nominal supply levels.
