NXP Semiconductors MF0MOU2101DA4,118

Overview

MF0MOU2101DA4,118 from NXP Semiconductors is a contactless ticket IC in the MIFARE Ultralight C family, designed for secure public transport and event ticketing systems. It implements ISO/IEC 14443 Type A RF interface at 13.56 MHz, features 1536-bit EEPROM with 32-bit OTP and 16-bit counter, and supports 3DES authentication for cryptographic integrity. Its 50 pF on-chip resonance capacitor enables compatibility with compact TFC.0 ticket formats.

For engineers reviewing the MF0MOU2101DA4,118 datasheet, MF0MOU2101DA4,118 pinout, MF0MOU2101DA4,118 application, or MF0MOU2101DA4,118 equivalent, this page delivers verified technical context, memory layout details, security configuration logic, and real-world deployment constraints for smart ticket system integration.

Technical Context

The MF0MOU2101DA4,118 integrates an RF interface compliant with ISO/IEC 14443-2/-3 Type A, including modulator/demodulator, rectifier, clock regenerator, and voltage regulator - all powered solely by the reader's RF field. Its digital control unit executes anticollision via 7-byte UID (cascade level 2), state-driven command interpretation, and true multi-card arbitration.

Security is enforced through hardware-accelerated 3DES coprocessor, field-programmable per-page and per-block read-only locking (with irreversible bit-wise OR write semantics), and authentication-configurable memory access starting at page 03h. Memory organization includes 48 pages × 32 bits, with dedicated OTP, counter, lock bytes, and key storage (pages 2Ch–2Fh).

FAQ

What is the primary function of MF0MOU2101DA4,118 in a smart ticket system?

The MF0MOU2101DA4,118 serves as a secure, contactless credential IC that stores and protects ticket data using ISO/IEC 14443-A RF communication, 1536-bit EEPROM, and hardware-accelerated 3DES authentication. In a smart ticket system, MF0MOU2101DA4,118 enables tap-and-go validation while preventing cloning through its unique 7-byte UID and cryptographic challenge-response protocol.

How does the 50 pF input capacitance of MF0MOU2101DA4,118 affect antenna design?

The 50 pF on-chip resonance capacitor in MF0MOU2101DA4,118 is specifically tuned for TFC.0 ticket formats, allowing use of smaller, lower-inductance antennas without external capacitors. This reduces bill-of-materials cost and simplifies mechanical integration in thin, flexible tickets - unlike the 16 pF variant which requires larger antenna loops for resonance.

Can MF0MOU2101DA4,118 be used without implementing 3DES authentication?

Yes, MF0MOU2101DA4,118 operates in unauthenticated mode by default: pages 04h–0Fh are freely readable/writable until AUTH0 is programmed. However, security-critical data (e.g., balances or keys) must reside beyond the AUTH0 threshold - and MF0MOU2101DA4,118 enforces strict 3DES session requirements for access to those protected regions.

What memory pages in MF0MOU2101DA4,118 are reserved for manufacturer data and cannot be modified?

In MF0MOU2101DA4,118, pages 00h–02h contain the 7-byte UID, BCC bytes, and internal lock byte defaults - all written and permanently write-protected during NXP production test. Specifically, SN0 (page 00h, byte 0) holds NXP's manufacturer ID (04h), and BCC0/BCC1 (pages 00h–01h) are computed checksums that remain immutable after shipment.

Is MF0MOU2101DA4,118 compatible with existing MIFARE Ultralight MF0ICU1 infrastructure?

MF0MOU2101DA4,118 maintains backward compatibility with MF0ICU1 for the first 512 bits (pages 03h–0Fh), including OTP and lock byte functionality. However, MF0MOU2101DA4,118 extends memory to 1536 bits and adds 3DES authentication - meaning legacy readers can access basic data, but full security features require updated firmware supporting MIFARE Ultralight C commands.
