Product details
Overview
AT88RF04C-MX1G from Microchip Technology (formerly Atmel) is a contactless 13.56 MHz RFID tag IC with 4-kbit user EEPROM, ISO/IEC 14443-2 & -3 Type B compliance, integrated 82 pF tuning capacitor, and cryptographic security features including 64-bit mutual authentication and four key sets. It operates in epoxy-glass 13 mm × 13 mm tag format for secure identification in access control systems.
For engineers reviewing the AT88RF04C-MX1G datasheet, AT88RF04C-MX1G pinout, AT88RF04C-MX1G application, or AT88RF04C-MX1G equivalent, key selection criteria include RF protocol compatibility (Type B only), zone-based access control, anti-tearing support, 100,000 write endurance, and −25°C to +70°C commercial temperature range.
Technical Context
The AT88RF04C-MX1G implements a fully compliant ISO/IEC 14443-2:2001 Type B RF interface with half-duplex 106 kbit/s data exchange and 2-byte CRC_B error detection. Its RF power harvesting eliminates battery requirements, and the integrated 82 pF ±10 pF tuning capacitor enables operation with a single external coil antenna.
Security architecture includes four independent user zones (128 bytes each), a 2-Kbit configuration zone with programmable AFI and polling response, four 64-bit crypto keys, four 24-bit password sets, and tamper sensors. Authentication and encryption modes are activated sequentially-first mutual authentication, then optional stream encryption using 64-bit keys.

Pinout & Package
AT88RF04C-MX1G is packaged as a 13 mm × 13 mm epoxy-glass RFID tag with no exposed pins; it interfaces exclusively via two RF terminals (AC1 and AC2) connected to an external planar coil antenna. The device has no conventional IC package or solderable leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | RF Antenna Terminal 1 | Connects to one end of external coil; forms resonant LC tank with internal 82 pF capacitor. |
| AC2 | RF Antenna Terminal 2 | Connects to other end of external coil; completes RF coupling path for power harvesting and bidirectional communication. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 14443-3 Slot-MARKER Anticollision | Enables reliable multi-tag enumeration in dense RF fields without reader-side firmware modification. |
| Four Independent User Zones | Allows application-specific partitioning (e.g., credential data, audit logs, biometric templates) with distinct access policies per zone. |
| 64-bit Mutual Authentication (ELVA licensed) | Prevents cloning and man-in-the-middle attacks by validating both tag and reader identity before sensitive operations. |
| Anti-tearing Function | Guarantees atomicity of writes during power interruption by buffering data and recovering on next power-up. |
| Transport Password ($30 1D D2) | Provides factory-default secure entry point to configuration memory, enabling controlled personalization in trusted environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure RFID memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP NT3H2111W0FHKH | 1.5 kbit user memory; NFC Forum Type 2 Tag compliant; no built-in tuning capacitor; requires external matching network. | Optimized for smartphone tap-to-read use cases; lacks mutual authentication and multi-zone crypto key management. | Select when NFC interoperability with consumer mobile devices is required over cryptographic strength. |
| Infineon SLI13S | 4 kbit memory; ISO/IEC 14443-3 Type A only; supports DESFire EV2 commands; no integrated tuning capacitor. | Designed for legacy Type A infrastructure; requires external 13.56 MHz oscillator and matching components. | Select for migration from existing Type A systems where cryptographic command set compatibility is critical. |
Compared with AT88RF04C-MX1G, the NT3H2111 offers broader NFC smartphone compatibility but weaker security primitives, while the SLI13S provides Type A ecosystem alignment at the cost of added external component count and absence of integrated tuning capacitance.

FAQ
What is the operating temperature range for AT88RF04C-MX1G?
The AT88RF04C-MX1G is rated for commercial operation from −25°C to +70°C. This range reflects its epoxy-glass tag construction and is validated per Atmel-8672CS datasheet Section 15. It does not support extended industrial (−40°C to +85°C) operation like the WA1 wafer variant.
Does AT88RF04C-MX1G support ISO/IEC 14443-3 Type A communication?
No, AT88RF04C-MX1G is compliant only with ISO/IEC 14443-2 and -3 Type B protocols. While its RF interface is tolerant of Type A signals (will not latch or lock up), it does not respond to or communicate using Type A modulation or frame formats.
How is the AT88RF04C-MX1G powered during operation?
The AT88RF04C-MX1G derives all operating power from the 13.56 MHz RF field generated by the reader via electromagnetic induction through its external coil antenna. No battery or external power source is required-the internal rectifier and regulator convert RF energy into usable DC voltage.
What security features are enabled by default on AT88RF04C-MX1G?
AT88RF04C-MX1G ships with all security features disabled. The transport password ($30 1D D2) must first be used to access the configuration zone, after which users can enable mutual authentication, zone-specific passwords, encryption, and anti-tearing via personalization commands defined in the datasheet.
Can AT88RF04C-MX1G be used without an external antenna coil?
No. AT88RF04C-MX1G requires connection to an external planar coil antenna between AC1 and AC2 terminals. Its integrated 82 pF tuning capacitor works with that external inductance to form the resonant LC tank necessary for RF power harvesting and communication-no internal antenna exists.
