Product details
Overview
MF1MOA4S50/D,118 from NXP Semiconductors is a MIFARE Classic 1K contactless smart card IC embedded in an MOA4 module format, featuring 1024 bytes of EEPROM organized in 16 sectors of 64 bytes each, ISO/IEC 14443A compliance up to Layer 3, and dual-key per sector access control - deployed in secure access control systems requiring tamper-resistant credential storage.
For engineers reviewing the MF1MOA4S50/D,118 datasheet, MF1MOA4S50/D,118 pinout, MF1MOA4S50/D,118 application, or MF1MOA4S50/D,118 equivalent, key selection criteria include sector-based authentication, 106 kbit/s RF data rate, 10-year data retention, 100,000 write endurance, and compatibility with existing MIFARE Classic infrastructure.
Technical Context
The MF1MOA4S50/D,118 implements the MIFARE Classic 1K protocol stack with hardware-based cryptographic authentication using Crypto-1 cipher, supporting bit-wise anticollision and cascaded 4-byte UID. It operates at 13.56 MHz and communicates via load modulation at 106 kbit/s, with memory access governed by sector-level access conditions defined in the access bits.
Its MOA4 module form factor integrates the MF1 IC S50 die with antenna coupling and encapsulation optimized for proximity card applications. The chip does not support DES/3DES encryption or T=1 protocol - distinguishing it from MIFARE DESFire variants - and lacks random number generation or FIPS 140-2 certification.
Key Specifications

Pinout & Package
MF1MOA4S50/D,118 is supplied in an MOA4 module format - a fully integrated, antenna-coupled contactless smart card module with no external electrical pins. It interfaces solely via electromagnetic induction (13.56 MHz) and contains no user-accessible terminals or solderable leads.
Key Features
| Feature | Design Value |
|---|---|

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 (Au-bumped) form - no integrated antenna or module packaging. | Requires custom antenna design and bonding; unsuitable for drop-in card replacement. | Select when integrating into proprietary inlays or hybrid cards with custom RF tuning. |
| MF1MOA2S50/D3F | Same MF1 IC S50 in MOA2 module - smaller footprint, lower antenna coupling efficiency, reduced operating distance. | Lower read range (~70 mm vs. ~100 mm) limits reliability in high-speed gate applications. | Select for space-constrained formats where full MOA4 performance is not required. |
Compared with MF1ICS5005W/V1D and MF1MOA2S50/D3F, the MF1MOA4S50/D,118 delivers certified module-level RF performance, pre-tuned antenna integration, and guaranteed 100 mm operating distance - reducing system validation effort and accelerating time-to-market for OEM card manufacturers.

FAQ
What is the memory organization of the MF1MOA4S50/D,118?
The MF1MOA4S50/D,118 contains 1024 bytes of EEPROM organized into 16 sectors, each comprising four blocks of 16 bytes. Each sector includes three data blocks and one sector trailer containing access keys and control bits - a structure that enables granular permission management across credential zones in the MF1MOA4S50/D,118.
Does the MF1MOA4S50/D,118 support MIFARE DESFire features like AES encryption?
No, the MF1MOA4S50/D,118 implements the MIFARE Classic 1K protocol with Crypto-1 stream cipher only and does not support AES, DES3, or T=1 protocol. It lacks random number generation and FIPS 140-2 certification - features found exclusively in MIFARE DESFire variants, not in the MF1MOA4S50/D,118.
What is the maximum operating distance for the MF1MOA4S50/D,118?
The MF1MOA4S50/D,118 achieves up to 100 mm operating distance under typical conditions with a standard ISO 14443A reader antenna. Performance depends on reader field strength, antenna alignment, and environmental interference - but the MOA4 module's pre-tuned design ensures consistent performance within this specification for the MF1MOA4S50/D,118.
Can the MF1MOA4S50/D,118 be used in multi-application deployments?
Yes, the MF1MOA4S50/D,118 supports the MIFARE Application Directory (MAD), allowing multiple independent applications to coexist on one card. Each application resides in its own sector with dedicated access keys - enabling secure separation of functions such as access control, e-purse, and ID verification on a single MF1MOA4S50/D,118 module.
Is the MF1MOA4S50/D,118 compatible with existing MIFARE Classic readers?
Yes, the MF1MOA4S50/D,118 is fully backward-compatible with all ISO/IEC 14443A Level 3 readers certified for MIFARE Classic 1K. Its protocol stack, UID format, and command set match legacy infrastructure - ensuring seamless integration without firmware updates or reader reconfiguration for the MF1MOA4S50/D,118.
