Product details
Overview
AT88SC0808CRF-MX1 from Microchip Technology (formerly Atmel) is a contactless 13.56 MHz CryptoRF EEPROM memory IC embedded in a 13 mm × 13 mm epoxy-glass RFID tag. It delivers 8 kilobits of user memory across eight 128-byte zones, ISO/IEC 14443-2 & -3 Type B compliance, and hardware-accelerated 64-bit mutual authentication under ELVA license - deployed in secure access cards, payment tokens, and government ID systems.
For engineers reviewing the AT88SC0808CRF-MX1 datasheet, AT88SC0808CRF-MX1 pinout, AT88SC0808CRF-MX1 application, or AT88SC0808CRF-MX1 equivalent, this page provides verified technical context on RF interface timing, zone-level access control, anti-tearing recovery behavior, tuning capacitor integration, and cryptographic mode activation sequences required for secure multi-card deployment.
Technical Context
The AT88SC0808CRF-MX1 implements a fully self-contained ISO/IEC 14443-3 Type B anticollision protocol with Slot-MARKER frame structure and 2-byte CRC_B error detection. Its RF interface draws power directly from the reader's 13.56 MHz field and integrates an 82 pF ±10% tuning capacitor between AC1 and AC2 terminals, eliminating external matching components.
Security operations are partitioned into three communication modes: Standard (clear data), Authentication (encrypted passwords + MAC), and Encryption (end-to-end encrypted payload + MAC). Each of the eight user zones supports independent password sets, key configurations, and access rights defined in the 2-Kbit configuration zone - including AFI programmability and tamper sensor enablement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency | 13.56 MHz - Operates exclusively within globally licensed HF ISM band; no external oscillator required. |
| User Memory | 8 kilobits (8 × 128-byte zones) - Enables segregated storage for credentials, biometrics, and audit logs per application domain. |
| Configuration Memory | 2 kilobits - Stores four crypto key sets, eight 24-bit password pairs, AFI, polling response, and zone-specific access registers. |
| Authentication | 64-bit Mutual Auth (ELVA licensed) - Requires challenge-response handshake before enabling encrypted mode; prevents replay attacks. |
| Endurance / Retention | 100,000 write cycles / 10 years data retention - Validated under commercial temperature range (−25°C to +70°C). |
| Operating Temp | −25°C to +70°C - Specifies full functionality for MX1 tag variant; differs from industrial −25°C to +85°C rating of base die. |
| Tuning Capacitance | 82 pF ±10% - Integrated between AC1–AC2; enables single-coil antenna design without external capacitors. |
Pinout & Package
AT88SC0808CRF-MX1 is supplied as a pre-assembled 13 mm × 13 mm epoxy-glass RFID tag with no user-accessible pins. The IC itself uses two RF terminals (AC1 and AC2) bonded to an internal planar coil; these are not externally exposed or routable. No discrete pinout applies - the device functions as a complete transponder module.
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 14443-2 & -3 Type B Compliance | Guarantees interoperability with standard HF readers and multi-card anticollision environments without firmware adaptation. |
| Zone-Level Access Control | Each of eight user zones enforces independent read/write passwords, crypto keys, and security fuse states - enabling true multi-application card architecture. |
| Anti-Tearing Recovery | Automatically restores corrupted writes after power loss by staging data in buffer EEPROM - critical for credential integrity during field interruption. |
| Transport Password Protection | Secure code $40 7F AB required to unlock configuration memory programming - prevents unauthorized personalization of AFI or key material. |
| Type A Signal Tolerance | Non-latching RF front-end survives exposure to ISO/IEC 14443-2 Type A fields without damage or functional reset - simplifies co-location in mixed-protocol zones. |
Applications
| Government ID Cards | Secure Payment Tokens |
|---|---|

FAQ
What is the exact package form factor of AT88SC0808CRF-MX1?
AT88SC0808CRF-MX1 is supplied as a finished 13 mm × 13 mm square epoxy-glass RFID tag on 35 mm tape with gold finish. It contains the AT88SC0808CRF die bonded to an internal planar coil - no user-accessible pins or solderable terminals are provided. The IC interfaces solely via its AC1 and AC2 RF terminals, which are not externally exposed.
Does AT88SC0808CRF-MX1 require external tuning components?
No. AT88SC0808CRF-MX1 integrates an 82 pF ±10% tuning capacitor between its AC1 and AC2 terminals. This eliminates the need for external capacitors in the antenna matching network, allowing direct connection of a single-loop coil antenna - a key design simplification confirmed in the Atmel-5027GS datasheet summary.
How does the anti-tearing function operate in AT88SC0808CRF-MX1?
In AT88SC0808CRF-MX1, anti-tearing safeguards write operations by first staging data in a dedicated EEPROM buffer zone before committing it to the target address. If power is lost mid-write, the device recovers the original or updated value from the buffer at next power-up - ensuring atomicity of credential updates without host-side transaction management.
What is the transport password for AT88SC0808CRF-MX1 configuration memory?
The transport password (secure code) for accessing the configuration memory of AT88SC0808CRF-MX1 is $40 7F AB in hexadecimal format. This value must be presented via the Check Password command before any programming of AFI, keys, or zone access registers - a factory-default credential documented in Section 7.7 of the datasheet summary.
Is AT88SC0808CRF-MX1 compliant with ISO/IEC 14443-3 Type B anticollision?
Yes. AT88SC0808CRF-MX1 fully complies with ISO/IEC 14443-3:2001 Type B, implementing the Slot-MARKER anticollision protocol. It supports WUPB/REQB commands, responds with UID and AFI, and guarantees interoperability with other Type B PICCs - including Atmel's AT88RF020 - as stated in Section 1 of the datasheet summary.
