MIFARE Ultralight® EV1

2023-10-30 View:

NXP® Semiconductors developed the MIFARE Ultralight EV1 MF0ULx1 for use in a contactless smart ticket, smart card, or token in combination with a Proximity Coupling Device (PCD). The MF0ULx1 is designed to work in an ISO/IEC 14443 Type-A compliant environment. The target applications include single trip or limited use tickets in public transport networks, loyalty cards or day passes for events. The MF0ULx1 serves as a replacement for conventional ticketing solutions such as paper tickets, magnetic stripe tickets or coins. It serves as a ticketing counterpart to 
contactless card families such as MIFARE DESFire® or MIFARE Plus®.
The MIFARE Ultralight EV1 is succeeding the MIFARE Ultralight ticketing IC and is fully functional backward compatible. Its enhanced feature and command set enables more efficient implementations and offers more flexibility in system designs.

The mechanical and electrical specifications of MIFARE Ultralight EV1 are tailored to meet the requirements of inlay and paper ticket manufacturers.

Contactless energy and data transfer
In a MIFARE® system, the MF0ULx1 is connected to a coil with a few turns. The MF0ULx1 fits the TFC.0 (Edmondson) and TFC.1 (ISO) ticket formats.

The MF0ULx1 chip, which features a 17 pF on-chip resonance capacitor, supports both TFC.1 and TFC.0 ticket formats.

An intelligent anti-collision function allows more than one card to operate in the field simultaneously. The anti-collision algorithm selects each card individually. It ensures that the execution of a transaction with a selected card is performed correctly without interference from another card in the field.

Simple integration and user convenience
The MF0ULx1 is designed for simple integration and user convenience, which allows complete ticketing transactions to be handled in less than 35 ms.
