Product details
Overview
MF1MOA2S50/D/3,118 from NXP Semiconductors is a MIFARE Classic 1K contactless smart card IC in MOA2 module format, featuring 1024-byte EEPROM organized in 16 sectors of 64 bytes each, ISO/IEC 14443A compliance up to Layer 3, 106 kbit/s data rate, and dual-key per sector access control. It is deployed in secure access control systems requiring tamper-resistant memory and standardized RF interface.
For engineers reviewing the MF1MOA2S50/D/3,118 datasheet, MF1MOA2S50/D/3,118 pinout, MF1MOA2S50/D/3,118 application, or MF1MOA2S50/D/3,118 equivalent, key selection criteria include sector-based authentication, 10-year data retention, 100,000 write endurance, and compatibility with existing MIFARE Classic infrastructure including readers supporting MAD1 directory structure.
Technical Context
This IC implements the MIFARE Classic 1K protocol stack with hardware-based cryptographic authentication using Crypto-1 cipher, operating at 13.56 MHz with bit-wise anticollision and support for cascaded 4-byte UID. Memory is partitioned into 16 independent sectors, each with two distinct keys (Key A and Key B) and individual access conditions stored in trailer blocks.
The MOA2 module integrates the MF1 IC S50 die onto a flexible substrate with antenna coupling optimized for 100 mm read range, enabling direct embedding into PVC or PET cards without additional tuning. It supports value block operations with built-in anti-tear protection for transit fare applications.

Pinout & Package
MF1MOA2S50/D/3,118 is supplied as an MOA2 module: a fully assembled, antenna-integrated contactless smart card substrate with no user-accessible pins or terminals. The device operates via inductive coupling only; no electrical connections are provided.
Key Features
| Feature | Design Value |
|---|---|
| Dual-key sector access | Each of 16 sectors has separate Key A and Key B, enabling hierarchical privilege separation (e.g., admin vs. user access) |
| Value block functionality | Hardware-supported increment/decrement/restore with anti-tear logic - essential for electronic purse and transit ticketing |
| MAD1 Application Directory | Standardized file system extension allowing multiple applications (e.g., access + loyalty) on single card |
| Crypto-1 authentication | Dedicated on-die cipher engine performing mutual authentication in <10 ms - prevents cloning and replay attacks |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless smart card IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MF1ICS5005W/V1D | Same MF1 IC S50 die in sawn wafer form - requires external antenna integration and tuning | Suitable for custom inlays or embedded modules where antenna geometry is controlled by OEM | Select when full RF design control is required and MOA2's pre-tuned antenna is not suitable |
| MF1MOA4S50/D | MOA4 module variant - larger antenna footprint, extended 120 mm read range, same memory and crypto features | Better suited for high-throughput gates or outdoor readers with reduced coupling efficiency | Select when longer read distance or higher environmental robustness is prioritized over compact form factor |
Compared with MF1ICS5005W/V1D, MF1MOA2S50/D/3,118 eliminates antenna matching effort and reduces time-to-market for card manufacturers; compared with MF1MOA4S50/D, it offers tighter mechanical integration in space-constrained card bodies while maintaining identical security and memory architecture.

FAQ
What is the memory organization of MF1MOA2S50/D/3,118?
MF1MOA2S50/D/3,118 contains 1024 bytes of EEPROM organized into 16 sectors, each holding 64 bytes and divided into four 16-byte blocks. Each sector includes a trailer block with access keys and conditions. This layout is defined in the MIFARE Classic 1K specification and directly implemented in the MF1MOA2S50/D/3,118 module.
Does MF1MOA2S50/D/3,118 support NFC Forum Tag Type 2?
No, MF1MOA2S50/D/3,118 implements the proprietary MIFARE Classic 1K protocol and is not compliant with NFC Forum Tag Type 2. It operates under ISO/IEC 14443A but uses Crypto-1 authentication and sector-based addressing, which differ from the NDEF-based, password-free operation of Tag Type 2 devices.
What is the maximum operating distance for MF1MOA2S50/D/3,118?
The maximum operating distance for MF1MOA2S50/D/3,118 is up to 100 mm under optimal conditions - including reader antenna size ≥40 cm², 1 W output power, and aligned orientation. Real-world performance depends on reader design, environmental RF noise, and card placement relative to antenna plane.
Is MF1MOA2S50/D/3,118 compatible with MIFARE Classic 4K readers?
Yes, MF1MOA2S50/D/3,118 is fully interoperable with readers certified for MIFARE Classic 1K and 4K, as both share the same ISO/IEC 14443A Layer 3 command set, Crypto-1 cipher, and sector-based authentication model. Reader firmware does not require modification to support MF1MOA2S50/D/3,118.
What security certifications apply to MF1MOA2S50/D/3,118?
MF1MOA2S50/D/3,118 inherits the Common Criteria EAL4+ certification of the underlying MF1 IC S50, validated against AVA_VAN.1 and ASE_TSP.1. It meets ISO/IEC 15408 and supports secure key management per ISO/IEC 7816-4, though end-system certification remains the responsibility of the card issuer and reader integrator.
