M62021L#TF0J

Supervisors Overview

The M62021L#TF0J is a system IC designed for memory backup functions in SRAM and microcomputer systems. It operates within a voltage range of 3V to 5.5V, featuring a detection voltage of 4.40V ±0.2V. The device includes a built-in switch for selecting between main and backup power supplies to RAM, with a typical input-output voltage difference of 0.2V at 80mA output current. It provides two reset outputs (RES/RES) and a chip select signal (CS). The component is housed in a TF0J package and supports variable delay times via external capacitance.

Supervisors Feature Summary

• Built-in switch for seamless selection between main power supply and backup power supply to RAM
• Dual reset outputs (RES/RES) for reliable microcomputer control during power-down events
• Low voltage drop characteristic with typical 0.2V difference at 80mA output current
• Variable delay time functionality facilitated by external capacitance connection

Supervisors Applications

• Power supply control systems for memory backup of microcomputer systems
• SRAM boards with built-in backup function requiring switching between external power supply and battery
• System reset IC applications for memory backup management

Supervisors Procurement Notes

Verify the specific suffix #TF0J against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as per the latest product change notices. Ensure compatibility with existing circuit designs regarding the 4.40V detection threshold and reset timing requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when designing systems requiring automated memory backup switching between main and battery power sources. Consider its low voltage drop feature for efficiency in 5V systems. Evaluate the need for dual reset outputs and variable delay capabilities based on system stability requirements. Ensure the operating temperature range meets application environmental conditions.
