Product details
Overview
AT88RF04C-MVA1 from Microchip Technology (acquired 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 from −40°C to +85°C and is embedded in an 8.6 mm × 18.1 mm epoxy-glass RFID tag for secure access control and credentialing.
For engineers reviewing the AT88RF04C-MVA1 datasheet, AT88RF04C-MVA1 pinout, AT88RF04C-MVA1 application, or AT88RF04C-MVA1 equivalent, this page delivers verified electrical parameters, memory zoning, RF interface behavior, security mode transitions, and real-world deployment constraints - all specific to the MVA1 tape-and-reel epoxy-glass tag variant.
Technical Context
The AT88RF04C-MVA1 implements a passive RF interface compliant exclusively with ISO/IEC 14443-2:2001 and -3:2001 Type B signaling, supporting half-duplex 106 kbit/s data exchange with 2-byte CRC_B error detection. Its RF power harvesting eliminates battery requirements, and its tolerance to Type A field modulation prevents latch-up without functional response.
Memory is partitioned into four 128-byte user zones and a 256-byte configuration zone containing four 24-bit password sets, four 64-bit crypto keys, AFI registers, and security fuses. Security operations include anti-tearing recovery, password attempt counters, and optional stream encryption activated post-authentication.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency | 13.56 MHz - Operates within globally licensed ISM band; requires external coil antenna tuned with internal 82 pF capacitor. |
| User Memory | 4 kbit (512 bytes) - Configured as four independent 128-byte zones; supports byte/page/partial-page writes with self-timed cycles. |
| Configuration Memory | 2 kbit (256 bytes) - Stores passwords, keys, AFI, anticollision responses, and access rights; locked via three OTP security fuses. |
| Security Protocol | 64-bit Mutual Authentication (ELVA licensed) - Enables secure session establishment before encrypted data exchange. |
| Write Endurance | 100,000 cycles per byte - Validated at industrial temperature range; anti-tearing mode reduces endurance to 50,000 writes. |
| Data Retention | 10 years at 55°C - Ensures long-term integrity of credentials and keys in deployed tags without refresh. |
| Operating Temp | −40°C to +85°C - Matches industrial-grade environmental requirements for outdoor access systems and asset tracking. |
Pinout & Package
AT88RF04C-MVA1 is packaged as an epoxy-glass RFID tag (8.6 mm × 18.1 mm) with two terminals: AC1 and AC2. No discrete package footprint or PCB mounting - the die is bonded directly to a planar coil antenna substrate. The device has no VDD/VSS pins; power is harvested wirelessly from the RF field.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | RF Antenna Terminal 1 | Connects to one end of external coil antenna; forms resonant LC tank with internal 82 pF capacitor. |
| AC2 | RF Antenna Terminal 2 | Connects to opposite end of external coil; completes RF coupling path for power harvesting and bidirectional communication. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 14443-2 & -3 Type B Compliance | Guarantees interoperability with standard PCD readers used in transit, ID, and secure access infrastructure. |
| Four Independent User Zones | Enables segregation of credential data (e.g., access level, biometric template, audit log) with distinct password/key protection per zone. |
| Secure Personalization Mode | Allows encrypted programming of secrets during initial provisioning, preventing exposure of keys on insecure channels. |
| Anti-tearing Function | Ensures atomic write completion across power interruptions by buffering data before final commit - critical for tamper-resilient logging. |
| Transport Password ($30 1D D2) | Provides factory-default entry point to configuration memory, enabling controlled personalization before security fuses are blown. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless secure memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP NT3H2111W0FHKH | 13.56 MHz Type A/B dual-interface; 2 kbit EEPROM; no integrated tuning cap; requires external matching network. | Supports Type A readers (e.g., Android NFC); lacks 64-bit mutual auth; uses AES-128 instead of ELVA protocol. | Select when multi-protocol reader compatibility is required and cryptographic licensing is unavailable. |
| Infineon SLE78CLX2040P | 13.56 MHz Type B only; 4 kbit EEPROM; integrated 82 pF cap; supports ISO/IEC 14443-4 T=CL; higher ECC support. | Includes full smart card OS stack and APDU command set; targets certified e-passport applications requiring Common Criteria EAL5+. | Select when full ISO/IEC 7816-4 compliance and certified OS execution are mandatory. |
Compared with NT3H2111W0FHKH and SLE78CLX2040P, the AT88RF04C-MVA1 offers optimized cost and size for dedicated Type B deployments where ELVA-licensed mutual authentication and anti-tearing resilience are prioritized over multi-protocol flexibility or full smart card OS features.

FAQ
What is the exact package form factor of AT88RF04C-MVA1?
AT88RF04C-MVA1 is supplied as an epoxy-glass RFID tag measuring 8.6 mm × 18.1 mm, with AC1 and AC2 terminals bonded directly to a planar coil antenna. It is not a surface-mount IC - no leads, pads, or PCB footprint; it functions as a complete passive transponder module.
Does AT88RF04C-MVA1 support ISO/IEC 14443-4 or T=CL protocol?
No. AT88RF04C-MVA1 implements only ISO/IEC 14443-2 and -3 Type B physical and anticollision layers. It does not support ISO/IEC 14443-4's T=CL transport protocol or APDU command structure - it uses a proprietary CryptoRF command set optimized for secure memory access.
What is the default transport password for AT88RF04C-MVA1 configuration access?
The default transport password for AT88RF04C-MVA1 is hexadecimal $30 1D D2. This value must be presented via the Check Password command to unlock access to the configuration memory before personalization and security fuse blowing.
Can AT88RF04C-MVA1 operate in environments with both Type A and Type B readers?
Yes - AT88RF04C-MVA1 is tolerant of Type A field modulation and will not latch up or sustain damage when exposed to Type A signals. However, it only responds to Type B commands; it remains silent and non-interactive in pure Type A fields.
How does anti-tearing function impact write performance in AT88RF04C-MVA1?
When anti-tearing is enabled, AT88RF04C-MVA1 limits write operations to 8-byte pages and extends write time due to dual-phase commit (buffer → destination). This ensures data integrity during power loss but reduces throughput compared to standard 16-byte page writes.
