Product details
Overview
AT88SC1616CRF-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 provides 16 kilobits of user memory (16 × 128-byte zones), ISO/IEC 14443-2 & -3 Type B compliance, integrated 82 pF tuning capacitor, and supports mutual authentication via 64-bit ELVA-licensed protocol. It is used in secure access cards, payment tokens, and credentialing systems requiring tamper-resistant data storage.
For engineers reviewing the AT88SC1616CRF-MX1 datasheet, AT88SC1616CRF-MX1 pinout, AT88SC1616CRF-MX1 application, or AT88SC1616CRF-MX1 equivalent, key selection criteria include RF interface compliance (Type B only), zone-level password/key access control, anti-tearing support, 100,000 write endurance, and −25°C to +85°C industrial temperature operation.
Technical Context
The AT88SC1616CRF-MX1 integrates an ISO/IEC 14443-2/3 Type B RF interface with on-die rectifier, regulator, clock extraction, and modulator circuitry - enabling passive operation powered solely by reader field coupling. Its RF front-end includes AC1/AC2 coil terminals, overvoltage clamp, and 82 pF ±10% integrated tuning capacitance.
Security execution relies on dedicated hardware blocks: four 64-bit crypto key sets, eight 24-bit password sets, password/authentication attempt counters, and a stream encryption unit. Memory access is enforced per-zone via configuration registers, with security fuses (module/card manufacturer/issuer) locking OTP portions of the 2-Kbit configuration zone.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Interface | 13.56 MHz, ISO/IEC 14443-2:2001 & -3:2001 Type B compliant; no Type A response - ensures interoperability with standard B readers and avoids protocol conflicts. |
| User Memory | 16 kbit EEPROM, organized as sixteen 128-byte zones; enables multi-application partitioning with independent access rights per zone. |
| Configuration Memory | 2 kbit EEPROM storing AFI, anticollision response, keys, passwords, and zone security registers; protected by three sequential OTP fuses. |
| Security Protocol | 64-bit Mutual Authentication (ELVA licensed), stream encryption, MAC-based checksum, and anti-tearing - prevents cloning, replay, and power-loss corruption. |
| Reliability | 100,000 write cycles and 10-year data retention at −25°C to +85°C - validated for industrial lifecycle requirements in deployed credential systems. |
| Tuning Capacitance | 82 pF ±10% between AC1–AC2 pins - eliminates need for external capacitor; simplifies antenna matching for 13 mm × 13 mm MX1 tag layout. |
| Communication Range | Up to 10 cm with ISO-compliant reader at max RF power - defines usable proximity for contactless transaction environments. |
Pinout & Package
AT88SC1616CRF-MX1 is supplied as a fully assembled 13 mm × 13 mm epoxy-glass RFID tag with two RF coil connection terminals: AC1 and AC2. No additional package or leadframe is present - the die is embedded directly into the tag substrate. The device has no conventional IC pins; AC1 and AC2 serve as bidirectional RF interface terminals for antenna coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | RF Coil Terminal 1 | Connects to one end of external planar antenna coil; forms resonant LC tank with internal 82 pF capacitor for 13.56 MHz operation. |
| AC2 | RF Coil Terminal 2 | Connects to other end of antenna coil; completes RF energy harvesting path and enables half-duplex data exchange at 106 kbps. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 14443-3 Slot-MARKER Anticollision | Enables reliable multi-card polling in dense RF fields without reader-side firmware modification - critical for access control gateways. |
| Zone-Level Access Control | Each of 16 user zones supports independent read/write passwords, crypto keys, and access rights - allows segregation of biometric, PIN, and credential data. |
| Transport Password Protection | Secure code $50 44 72 required to access configuration memory - prevents unauthorized personalization during card issuance. |
| Anti-Tearing Function | Automatically recovers incomplete writes after power loss using buffer-zone duplication - guarantees atomicity of financial or identity updates. |
| Type A Signal Tolerance | Non-latching behavior under Type A field exposure - permits co-location with Type A infrastructure without malfunction or damage. |

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 | 13.56 MHz Type A/B dual-interface; 2 Kbyte EEPROM; no integrated tuning cap; requires external antenna matching. | Supports Type A readers (e.g., Android NFC); lower memory density; lacks anti-tearing and ELVA authentication. | Select when multi-protocol reader compatibility is mandatory and cryptographic depth is secondary to cost and footprint. |
| Infineon SLE78CLFX2000P | 13.56 MHz Type B only; 16 Kbyte EEPROM; certified Common Criteria EAL5+; no integrated tuning cap; larger 18.1 mm × 8.6 mm MVA1 form factor. | Targeted at high-assurance government PKI; includes JavaCard OS support; higher certification overhead than AT88SC1616CRF-MX1. | Select when formal security certification (e.g., FIPS 140-2) is contractually required and MX1's 13 mm square size is not constraining. |
Compared with NT3H2211W0FHKH and SLE78CLFX2000P, the AT88SC1616CRF-MX1 uniquely combines integrated 82 pF tuning, compact 13 mm² epoxy-glass tag format, and ELVA-licensed mutual authentication - optimizing for rapid deployment in mid-assurance physical access and credentialing systems where board space and antenna design simplicity are critical.

FAQ
What is the operating temperature range for AT88SC1616CRF-MX1?
The AT88SC1616CRF-MX1 is rated for industrial operation from −25°C to +85°C. This specification is confirmed in the official Atmel-5026GS datasheet summary, Section 10 "Ordering Information", and applies specifically to the MX1 package variant. The extended low-temperature limit distinguishes it from commercial-grade variants like MVA1 (−25°C to +70°C), making AT88SC1616CRF-MX1 suitable for outdoor access control and factory-floor deployments.
Does AT88SC1616CRF-MX1 support ISO/IEC 14443 Type A communication?
No, AT88SC1616CRF-MX1 is strictly ISO/IEC 14443-2 and -3 Type B compliant. However, its RF interface is tolerant of Type A signals - meaning it will not latch or sustain damage if exposed to Type A field modulation, though it remains non-responsive. This tolerance is documented in Section 3.3 "Type A Tolerance" of the datasheet summary and enables safe co-location with mixed-protocol infrastructure.
How is antenna tuning handled on AT88SC1616CRF-MX1?
The AT88SC1616CRF-MX1 integrates an 82 pF ±10% tuning capacitor between AC1 and AC2 terminals. This eliminates the need for external capacitors and simplifies antenna design - users only require a properly sized planar coil tuned to resonance at 13.56 MHz using this fixed internal capacitance. The value is specified in Section 8 "Tuning Capacitance" and verified across process and temperature.
What security features differentiate AT88SC1616CRF-MX1 from basic RFID tags?
AT88SC1616CRF-MX1 includes hardware-accelerated 64-bit mutual authentication (under ELVA license), stream encryption, Message Authentication Code (MAC)-based checksums, anti-tearing recovery, eight 24-bit password sets, and four 64-bit key sets - all enforced per-zone. Unlike basic tags, it provides cryptographic assurance of data origin and integrity, not just identification. These features are detailed in Sections 6–7 of the datasheet summary.
Is the configuration memory of AT88SC1616CRF-MX1 writable after personalization?
Portions of the 2-Kbit configuration memory in AT88SC1616CRF-MX1 are permanently locked via three OTP security fuses (module, card manufacturer, issuer), as defined in Section 5.1. While initial personalization uses the transport password $50 44 72 to program AFI, keys, and passwords, fuse blowing renders critical registers immutable - ensuring tamper-proof credential binding. This behavior is mandatory for trusted issuance workflows.
