Product details
Overview
AT88SC0808CRF-MVA1 from Microchip Technology (formerly Atmel) is a contactless 13.56 MHz RFID tag IC with 8 kilobits of user EEPROM memory, ISO/IEC 14443-2 and -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 industrial temperature range (−25°C to +85°C) and is embedded in an 8.6 mm × 18.1 mm epoxy-glass RFID tag format for secure access control applications.
For engineers reviewing the AT88SC0808CRF-MVA1 datasheet, AT88SC0808CRF-MVA1 pinout, AT88SC0808CRF-MVA1 application, or AT88SC0808CRF-MVA1 equivalent, this page delivers verified technical context, exact memory zoning (eight 128-byte user zones), RF interface timing, security mode transitions, and real-world deployment constraints - all specific to the MVA1 tape-mounted epoxy-glass tag variant.
Technical Context
The AT88SC0808CRF-MVA1 implements a fully compliant ISO/IEC 14443-2:2001 Type B RF interface with half-duplex 106 kbit/s data exchange, 2-byte CRC_B error detection, and Slot-MARKER anticollision protocol. Its RF front-end includes on-die rectifier, regulator, clock extraction, and modulator - powered solely by the reader's RF field.
Security operations are partitioned across three modes: Standard (clear data, clear passwords, MDC), Authentication (clear data, encrypted passwords, MAC), and Encryption (encrypted data and passwords, MAC). Memory access is enforced per-zone via eight 24-bit password sets, four 64-bit crypto key sets, and tamper-sensing logic tied to anti-tearing recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency | 13.56 MHz - Operates exclusively within globally licensed HF ISM band; requires no external oscillator or clock source. |
| User Memory | 8 kilobits (1024 bytes) - Organized as eight independent 128-byte zones; supports byte/page/partial-page writes with self-timed cycles. |
| Configuration Memory | 2 kilobits (256 bytes) - Stores AFI, anticollision response, four key sets, eight password sets, and zone-level access rights registers. |
| Tuning Capacitance | 82 pF ±10% - Integrated on-die capacitor between AC1/AC2 pins; eliminates need for external tuning components in antenna design. |
| Operating Temperature | −25°C to +85°C - Validated for industrial environments; enables deployment in outdoor access terminals and unconditioned infrastructure. |
| Data Retention | 10 years - Guaranteed retention under specified temperature and voltage conditions; critical for long-lifecycle credential storage. |
| Write Endurance | 100,000 cycles - Sufficient for repeated reprogramming in multi-use smart card or asset tagging applications. |
Pinout & Package
AT88SC0808CRF-MVA1 is supplied as an epoxy-glass RFID tag (8.6 mm × 18.1 mm) with two electrical terminals: AC1 and AC2. These connect directly to the external coil antenna. No additional power supply, ground, or digital I/O pins are present - operation is fully passive and RF-coupled.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | RF Antenna Terminal 1 | Connects to one end of external planar 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 energy harvesting and bidirectional communication. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 14443-3 Type B Anticollision | Enables reliable multi-tag reading in dense environments (e.g., badge issuance stations) using REQB/WUPB commands and AFI-based filtering. |
| Zone-Level Access Control | Each of eight user zones can be assigned unique read/write passwords and crypto keys - supporting multi-application cards (e.g., physical access + loyalty + time tracking). |
| Anti-Tearing Recovery | Automatically restores EEPROM integrity after power loss during write; uses buffer-zone duplication without host intervention. |
| Transport Password Protection | Secure code $40 7F AB required to access configuration memory - prevents unauthorized personalization of security settings during manufacturing. |
| Type A Signal Tolerance | Remains functional and non-latching when exposed to ISO/IEC 14443-2 Type A fields - simplifies coexistence in mixed-protocol reader deployments. |
Applications
| Physical Access Control | Government ID Cards |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless secure memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT88SC0808CRF-MX1 | 13 mm × 13 mm square epoxy-glass tag; same die, identical memory map and security features; commercial temp range (−25°C to +70°C). | Suitable for compact form-factor badges where square footprint aligns with standard card layouts. | Select MX1 for space-constrained designs requiring identical functionality but different mechanical envelope. |
| NXP NT3H2201W0FHKH | 13.56 MHz NFC Forum Type 4 Tag compliant; 2 Kbyte NDEF memory; no built-in crypto engine or mutual authentication; supports AES-128 only via host-side processing. | Targeted at NFC smartphone interaction (e.g., tap-to-launch apps), not high-assurance authentication systems. | Select NT3H2201 for consumer-facing NFC use cases where host-initiated encryption suffices and mutual auth is unnecessary. |
Compared with AT88SC0808CRF-MX1, the AT88SC0808CRF-MVA1 offers extended industrial temperature support and rectangular geometry optimized for linear antenna integration; versus NT3H2201, it provides on-die cryptographic primitives and ISO/IEC 14443-3 Type B interoperability essential for legacy reader ecosystems.

FAQ
What is the operating temperature range for AT88SC0808CRF-MVA1?
The AT88SC0808CRF-MVA1 is rated for −25°C to +85°C, meeting industrial-grade environmental requirements. This range is validated per the datasheet and applies specifically to the MVA1 epoxy-glass tag variant - enabling reliable operation in outdoor access terminals, unconditioned server rooms, and factory-floor equipment.
Does AT88SC0808CRF-MVA1 require an external tuning capacitor?
No. The AT88SC0808CRF-MVA1 integrates an 82 pF ±10% capacitor between AC1 and AC2 terminals. This eliminates the need for external capacitors in antenna matching networks - reducing bill-of-materials count and simplifying PCB or tag layout for designers.
How many user memory zones does AT88SC0808CRF-MVA1 support?
The AT88SC0808CRF-MVA1 supports exactly eight user memory zones, each 128 bytes (1 kilobit) in size. These zones are independently configurable for read/write access, password protection, and cryptographic key assignment - enabling true multi-application credential use.
What security protocols does AT88SC0808CRF-MVA1 implement?
The AT88SC0808CRF-MVA1 implements ISO/IEC 14443-2 and -3 Type B compliance, 64-bit mutual authentication (under ELVA license), stream encryption, four key sets, eight 24-bit password sets, and anti-tearing recovery. All security functions are executed on-die without host processor involvement.
Is AT88SC0808CRF-MVA1 compatible with ISO/IEC 14443-3 Type A readers?
No. The AT88SC0808CRF-MVA1 is strictly ISO/IEC 14443-3 Type B compliant. However, its RF interface is tolerant of Type A signals - meaning exposure to Type A fields will not damage the device or cause latch-up, though it will not respond to them.
