Product details
Overview
AT88SC0808CRF-MVB1G from Microchip Technology (formerly Atmel) is a contactless 13.56MHz CryptoRF EEPROM memory IC with 8 kilobits of user memory, ISO/IEC 14443-2 & -3 Type B compliance, integrated 82pF tuning capacitor, and hardware-based 64-bit mutual authentication under ELVA license. It serves as a secure, battery-free smart card IC for RF identification and encrypted data storage in access control systems.
For engineers reviewing the AT88SC0808CRF-MVB1G datasheet, AT88SC0808CRF-MVB1G pinout, AT88SC0808CRF-MVB1G application, or AT88SC0808CRF-MVB1G equivalent, key selection criteria include RF interface compliance (Type B only), zone-level password/key access control, anti-tearing recovery, tamper sensing, and 100,000 write cycle endurance - all verified in the official Atmel-5027GS summary datasheet.
Technical Context
The AT88SC0808CRF-MVB1G implements a dedicated RF interface compliant exclusively with ISO/IEC 14443-2:2001 and -3:2001 Type B signaling, including Slot-MARKER anticollision protocol and 106 Kbit/s half-duplex communication with 2-byte CRC_B error detection. It requires no external power source, drawing energy from the reader's RF field via integrated rectifier and regulator circuitry.
Security operations are enforced through four independent key sets, eight 24-bit password sets, per-zone access rights, and three programmable security fuses (module manufacturer/card manufacturer/card issuer). Authentication and encryption modes are stateful and persist until power loss, DESELECT, or IDLE command - not automatically reset after each transaction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency | 13.56 MHz - Enables interoperability with standard ISO/IEC 14443-2 Type B readers and infrastructure. |
| User Memory | 8 kilobits (eight 128-byte zones) - Supports multi-application partitioning with independent access controls per zone. |
| Configuration Memory | 2 kilobits - Stores AFI, anticollision response, keys, passwords, and zone-specific security registers. |
| Write Endurance | 100,000 cycles - Guarantees long-term reliability for high-frequency credential updates in physical access systems. |
| Data Retention | 10 years - Ensures persistent storage integrity without refresh in ambient temperature environments. |
| Operating Temp | −25°C to +85°C - Validated for industrial-grade deployment in outdoor access panels and uncontrolled enclosures. |

Pinout & Package
AT88SC0808CRF-MVB1G is supplied in an epoxy-glass RFID tag package measuring 8.6 mm × 18.1 mm (MVA1 form factor), with two terminals: AC1 and AC2. These terminals connect directly to the external coil antenna and serve as the sole electrical interface - no VDD, VSS, or digital I/O pins are present. The device draws power and communicates entirely through the RF field.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Antenna Coil Terminal 1 | Connects to one end of external planar coil; forms resonant LC tank with internal 82pF capacitor. |
| AC2 | Antenna Coil Terminal 2 | Connects to opposite end of external coil; completes RF coupling path for power harvesting and bidirectional data exchange. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 14443-2 & -3 Type B Compliance | Ensures interoperability with certified Type B readers and supports standardized anticollision in multi-card environments. |
| Hardware Mutual Authentication | 64-bit protocol licensed from ELVA provides cryptographic proof of card identity without host-side crypto acceleration. |
| Zone-Level Access Control | Eight user zones each support independent read/write passwords, encryption keys, and security fuse locking - enabling multi-tenant credential management. |
| Anti-Tearing Recovery | Automatically restores corrupted writes after power interruption by staging data in buffer EEPROM before committing to final address. |
| Tamper Sensing | Detects physical intrusion attempts and triggers irreversible security responses, protecting stored keys and credentials. |
Applications
| Physical Access Control | Secure Transit Ticketing |
|---|---|
Use Scenario: Contactless employee badge used at door readers in corporate campuses and secure facilities. IC Role / Device Role / Timing Role: Secure credential storage and cryptographic authentication endpoint - no microprocessor required. Use Value: Prevents cloning via 64-bit mutual authentication and enforces per-zone access policies (e.g., floor-specific permissions). | Use Scenario: Reusable transit card supporting fare deduction, balance inquiry, and trip history logging across metro networks. IC Role / Device Role / Timing Role: Tamper-resistant, low-power memory node storing encrypted balance and audit logs - powered solely by reader field. Use Value: Anti-tearing function ensures transaction atomicity during rapid tap-in/tap-out; 10-year data retention avoids card replacement cycles. |
| Government ID Cards | Healthcare Credential Tokens |
Use Scenario: National e-ID card embedding biometric template references and citizenship status flags. IC Role / Device Role / Timing Role: Cryptographically sealed configuration zone stores Application Family Identifier (AFI) and issuer-defined polling response for selective activation. Use Value: AFI programmability allows coexistence of multiple government applications (e.g., tax, health, voting) on same card without interference. | Use Scenario: Hospital staff token granting role-based access to electronic health records and medication dispensers. IC Role / Device Role / Timing Role: Hardware-enforced password and key isolation between clinical, administrative, and pharmacy zones. Use Value: Eight independent 24-bit password sets enable granular authorization tiers without software overhead or firmware updates. |
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 NT3H2211W0FHKH | 13.56MHz Type A/B dual-interface; 2KB user memory; NFC Forum Tag Type 4B compliant; no integrated tuning capacitor. | Supports NFC smartphone interaction (Type A) and legacy Type B readers; requires external matching network. | Select when NFC peer-to-peer or smartphone-read capability is required; avoid if strict ISO/IEC 14443-3 Type B interoperability is mandatory. |
| Infineon SLE78CLX2000P | 13.56MHz Type B; 8KB user EEPROM; includes embedded 8051 CPU; supports Java Card OS; higher power consumption. | Enables dynamic applet execution and complex cryptographic operations beyond static memory storage. | Select when application requires on-card processing (e.g., dynamic OTP generation); avoid for pure secure memory use cases due to cost and complexity. |
Compared with AT88SC0808CRF-MVB1G, the NT3H2211W0FHKH offers broader protocol flexibility but lacks integrated tuning and hardware mutual authentication, while the SLE78CLX2000P adds computational capability at the expense of power efficiency and bill-of-materials simplicity.

FAQ
What is the RF interface standard compliance of the AT88SC0808CRF-MVB1G?
The AT88SC0808CRF-MVB1G is fully compliant with ISO/IEC 14443-2:2001 and ISO/IEC 14443-3:2001 for Type B only - including bit timing, signal modulation, and Slot-MARKER anticollision protocol. It does not support Type A signaling, though it tolerates exposure without damage or lockup.
Does the AT88SC0808CRF-MVB1G require an external tuning capacitor?
No, the AT88SC0808CRF-MVB1G integrates an 82pF tuning capacitor between AC1 and AC2 terminals. This eliminates the need for external capacitors and simplifies antenna design to a single external coil - a key differentiator versus competing contactless EEPROMs.
How is memory organized in the AT88SC0808CRF-MVB1G?
The AT88SC0808CRF-MVB1G contains 8 kilobits of user memory divided into eight 128-byte zones, plus 2 kilobits of configuration memory. The configuration zone holds four key sets, eight 24-bit passwords, AFI, anticollision response, and security fuses - all programmable during personalization.
What security mechanisms does the AT88SC0808CRF-MVB1G implement?
The AT88SC0808CRF-MVB1G implements hardware-based 64-bit mutual authentication (under ELVA license), stream encryption, encrypted checksums (MAC), anti-tearing recovery, tamper sensors, and three sequential security fuses. Access rights are configurable per user zone using passwords and keys stored in protected configuration memory.
What is the operating temperature range for the AT88SC0808CRF-MVB1G?
The AT88SC0808CRF-MVB1G is rated for operation from −25°C to +85°C, qualifying it for industrial-grade deployment in outdoor access control panels, unheated transit gates, and other environments with wide thermal excursions - as confirmed in the Atmel-5027GS summary datasheet.
