Product details
Overview
AT88SC6416CRF-MVA1 from Microchip Technology (formerly Atmel) is a contactless 13.56 MHz RFID tag IC with 64-kbit user EEPROM, ISO/IEC 14443-2 & -3 Type B compliance, integrated 82 pF tuning capacitor, and hardware-based 64-bit mutual authentication. It operates in −25°C to +85°C and delivers 100,000 write cycles for secure credential storage in physical access control systems.
For engineers reviewing the AT88SC6416CRF-MVA1 datasheet, AT88SC6416CRF-MVA1 pinout, AT88SC6416CRF-MVA1 application, or AT88SC6416CRF-MVA1 equivalent, key selection criteria include RF protocol compatibility (Type B only), zone-level password/key access control, anti-tearing support, tamper sensing, and epoxy-glass MVA1 tag form factor (8.6 mm × 18.1 mm).
Technical Context
The AT88SC6416CRF-MVA1 implements a dedicated RF interface compliant exclusively with ISO/IEC 14443-2:2001 and -3:2001 Type B signaling, including Slot-MARKER anticollision and 106 kbps half-duplex data exchange with 2-byte CRC_B error detection. It requires no internal power source - energy is harvested from the reader's RF field via its integrated 82 pF capacitor and external coil antenna.
Security is enforced through four independent key sets, eight 24-bit password sets, per-zone access rights, and three OTP security fuses (module/card manufacturer/issuer). Authentication and encryption modes are stateful and persist until power loss or explicit DESELECT/IDLE command, enabling layered protection for multi-application cards.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
AT88SC6416CRF-MVA1 is supplied as an epoxy-glass RFID tag (8.6 mm × 18.1 mm) with two terminals: AC1 and AC2. These connect directly to an external planar coil antenna; no additional pins or package leads are present. The device lacks conventional IC packaging - it is a bare-die-in-epoxy construction optimized for embedding into smart labels or cards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Antenna Coil Terminal 1 | Connects to one end of external LC resonator coil; forms part of 13.56 MHz tank circuit with integrated 82 pF capacitor. |
| AC2 | Antenna Coil Terminal 2 | Connects to opposite end of external coil; completes resonant circuit for RF power harvesting and bidirectional communication. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 14443-3 Type B Anticollision | Enables reliable multi-card polling in dense reader fields using REQB/WUPB commands and AFI-based discrimination. |
| Zone-Level Access Control | Each of 16 user zones supports independent password sets, key assignments, and read/write permissions configured in EEPROM. |
| Anti-Tearing Function | Guarantees atomicity of 8-byte page writes via buffer-and-commit mechanism, preventing data corruption during RF field dropout. |
| Tamper Sensors | Detect physical intrusion attempts (e.g., delamination, probing) and trigger irreversible security responses including memory lock. |
| Type A Signal Tolerance | Remains functional and non-latching when exposed to ISO/IEC 14443-2 Type A modulation - critical for mixed-protocol reader environments. |
Applications
| Physical Access Control | Secure Transit Ticketing |

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 NTAG 424 DNA | 13.56 MHz Type A only; 888-byte user memory; AES-128 crypto engine; no integrated tuning cap. | Optimized for NFC smartphone interaction and cloud-connected services; lacks Type B interoperability. | Select when NFC phone tap-to-authenticate UX is required and ISO/IEC 14443-2 Type B infrastructure is absent. |
| Infineon SLE 78CLFX2040P | 13.56 MHz Type A/B dual-mode; 2048-byte EEPROM; CC EAL5+ certified; requires external tuning components. | Targeted at high-assurance government PKI and banking cards; higher certification overhead and cost. | Select when Common Criteria EAL5+ validation is mandated and dual-protocol flexibility justifies added design complexity. |
Compared with NTAG 424 DNA and SLE 78CLFX2040P, the AT88SC6416CRF-MVA1 uniquely combines ISO/IEC 14443-2/-3 Type B compliance, integrated 82 pF capacitor, 64-kbit memory, and ELVA-licensed mutual authentication in a low-cost epoxy-glass tag format - making it optimal for industrial access control and transit systems built on legacy Type B infrastructure.

FAQ
What is the primary function of the AT88SC6416CRF-MVA1 in a contactless system?
The AT88SC6416CRF-MVA1 serves as a secure, contactless smart card IC with 64-kbit user EEPROM and hardware-accelerated cryptography. It enables mutual authentication, encrypted data exchange, and zone-level access control over ISO/IEC 14443-2/-3 Type B RF links - all powered passively from the reader's field. Its role is to store and protect sensitive credentials without requiring onboard power or a microprocessor.
Does the AT88SC6416CRF-MVA1 support ISO/IEC 14443-2 Type A communication?
No, the AT88SC6416CRF-MVA1 is compliant only with ISO/IEC 14443-2 and -3 Type B. However, its RF interface is tolerant of Type A signals - meaning exposure to Type A modulation will not damage the device or cause latch-up, though it will not respond to Type A commands. This tolerance supports operation in mixed-protocol environments without hardware redesign.
How is memory organized in the AT88SC6416CRF-MVA1?
The AT88SC6416CRF-MVA1 organizes memory into sixteen 512-byte user zones (totaling 64 kbits) plus a 256-byte configuration zone. Each user zone supports independent password and key access controls. The configuration zone stores Application Family Identifier (AFI), anticollision response, four key sets, eight 24-bit passwords, and security fuses - all programmable during personalization using the transport password $70BA2E.
What is the purpose of the integrated 82 pF capacitor in the AT88SC6416CRF-MVA1?
The integrated 82 pF capacitor (±10% tolerance) forms part of the resonant LC tank circuit with the external coil antenna, eliminating the need for discrete tuning capacitors. This simplifies tag design, improves manufacturing yield, and ensures consistent 13.56 MHz resonance across temperature and process variation - directly enabling reliable RF power harvesting and communication up to ~10 cm range with compliant readers.
Can the AT88SC6416CRF-MVA1 be used in automotive or safety-critical applications?
No - according to Microchip's official documentation, the AT88SC6416CRF-MVA1 is not designed, qualified, or warranted for automotive, safety-critical, or life-support applications. It is rated for industrial temperature range (−25°C to +85°C) and intended for physical access control, transit, and e-ID systems where failure does not reasonably risk injury or death. Use in automotive contexts requires explicit written consent from a Microchip officer.
