NCN6011DMR2

Translators, Level Shifters Overview

The NCN6011DMR2 is a low power level shifter designed to translate voltages between a SIM card and an external microcontroller. It supports input and output voltage ranges from 2.7 V to 6.0 V with a quiescent supply current of 500 nA. The device handles all signals required for data transactions, including clock, reset, and bidirectional I/O. It supports clock frequencies up to 10 MHz and includes logic I/O enable functionality. The component features fully ESD protected pins and provides Rx/Tx communication capability for smart card interfaces.

Translators, Level Shifters Feature Summary

• Translates voltage levels between external microcontrollers and SIM cards across a wide supply range
• Provides bidirectional serial I/O translation with built-in pull-up resistors for high impedance states
• Includes logic I/O enable function to control signal direction and release the I/O line
• Features Schmitt trigger inputs to prevent uncontrolled operation from noise or slow signals

Translators, Level Shifters Applications

• SIM/GSM/SMARTCARD interface circuits
• Voltage translation between MPU and Class A (5.0 V) smart cards
• Voltage translation between MPU and Class B (3.0 V) smart cards

Translators, Level Shifters Procurement Notes

Verify the DM suffix indicates the Micro-10 package (Case 846B) when ordering. Confirm the device meets ISO7816-3 specifications for your specific application requirements. Ensure PCB layout follows guidelines to minimize cross-talk on high-frequency clock lines. Validate electrical parameters for your specific operating temperature and voltage conditions before final design integration.

Translators, Level Shifters Selection Notes

Select this component when interfacing microcontrollers operating at different voltage levels with smart cards. It is suitable for applications requiring low standby current and robust ESD protection on card-side pins. Consider the Micro-10 package size if space constraints exist. Ensure the system design accounts for the lack of internal voltage regulation on the SIM_VCC pin.

Translators, Level Shifters Part Context

The NCN6011 series consists of low power level shifters for smart card interfaces. The NCN6011DMR2 specifically utilizes the Micro-10 package. Other variants include the DTB suffix for TSSOP-14 packaging. The device family is designed to handle all necessary signals for controlling data transactions between external controllers and SIM cards without affecting logic functions.

Translators, Level Shifters Replacement Considerations

NCN6011DTBR2: TSSOP-14 package variant with identical electrical characteristics. NCN6011DTB: Non-reel TSSOP-14 package variant. Verify package dimensions and pinout compatibility before substitution.
