X90100M8IT1

Overview

The X90100M8IT1 is a non-volatile electronically programmable capacitor manufactured by Renesas Electronics Corporation in an 8-lead MSOP package. It provides 32 selectable capacitance values ranging from 7.5pF to 14.5pF with 0.23pF increments in single-ended mode. The device utilizes internal EEPROM storage to retain programmed trim codes without DC power, featuring power-on recall capabilities. It operates on a supply voltage between 2.7V and 5.5V and uses a simple three-pin digital interface (INC, U/D, CS) for adjustments.

Feature Summary

• Non-volatile EEPROM storage retains capacitance settings across power cycles
• Capacitance range of 7.5pF to 14.5pF with 0.23pF resolution
• Low temperature drift coefficient (<50ppm/°C) in differential mode
• Fast incremental change time of 5µs maximum

Applications

• Post-trim of low-cost regenerative receivers
• Tunable RF stages
• Low-cost, low temperature drift oscillators
• Garage door openers and keyless entry systems
• Industrial wireless control and RFID tags

Procurement Notes

Verify the specific ordering suffix 'T1' corresponds to the Tape & Reel packaging configuration as indicated in official documentation. Confirm that the component meets all necessary environmental compliance standards required for the intended deployment environment before finalizing procurement.

Selection Notes

Select this component when a digitally adjustable, non-volatile capacitance solution is required to replace mechanical trimmers. Ensure the application supports the 2.7V to 5.5V supply range and utilizes a compatible serial interface for INC, U/D, and CS signals. Verify that the 8-MSOP package dimensions fit the available PCB space constraints.

Part Context

This part belongs to the X90100 series of NV Electronically Programmable Capacitors. The 'M8I' designation indicates the 8-lead MSOP package and industrial temperature range (-40°C to +85°C), while the 'T1' suffix specifies the tape and reel packaging format for automated assembly processes.

Replacement Considerations

Direct replacements must match the 8-MSOP footprint and provide similar capacitance ranges. Verify pinout compatibility for VCC, GND, Cp, Cm, and the three control pins. Check if alternative devices offer comparable linearity error specifications and EEPROM endurance ratings.
