Product details
Overview
AT88SC1616CRF-MY1 from Microchip Technology (formerly Atmel) is a contactless 13.56 MHz CryptoRF EEPROM memory IC designed for secure RF smart cards and tamper-resistant data storage. It delivers 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 licensed 64-bit protocol. It operates without battery, powered solely by RF field, and targets secure access control systems.
For engineers reviewing the AT88SC1616CRF-MY1 datasheet, AT88SC1616CRF-MY1 pinout, AT88SC1616CRF-MY1 application, or AT88SC1616CRF-MY1 equivalent, key selection criteria include ISO Type B anticollision interoperability, zone-level password/key access control, anti-tearing recovery, 100,000 write endurance, and industrial temperature range support - all confirmed for this specific ordering variant.
Technical Context
The AT88SC1616CRF-MY1 implements a dedicated RF interface compliant exclusively with ISO/IEC 14443-2:2001 and -3:2001 Type B signaling, modulation, and Slot-MARKER anticollision protocol - it does not support Type A communication but tolerates incidental Type A field exposure without latch-up. Its internal rectifier, regulator, and clock extraction circuitry derive full power and timing from the 13.56 MHz carrier, eliminating external power sources.
Security operations are enforced through hierarchical access: transport password ($50 44 72) unlocks configuration memory; eight 24-bit password sets and four 64-bit key sets enable per-zone read/write/authentication/encryption rights; and security fuses (module/card manufacturer/issuer) permanently lock OTP-protected configuration segments after personalization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Interface | 13.56 MHz ISO/IEC 14443-2 & -3 Type B only - ensures interoperability with standard Type B readers and anticollision with AT88RF020. |
| User Memory | 16 kbit EEPROM (16 × 128-byte zones) - enables multi-application data segregation with independent access controls per zone. |
| Configuration Memory | 2 kbit EEPROM - stores eight 24-bit passwords, four 64-bit crypto keys, AFI, polling response, and zone-specific security registers. |
| Security Protocol | 64-bit Mutual Authentication (ELVA licensed) + stream encryption + MAC-based checksum - provides cryptographic data origin verification and confidentiality. |
| Reliability | 100,000 write cycles / 10-year data retention - validated for high-cycle secure credential updates in deployed smart cards. |
| Operating Temp | −25°C to +85°C - supports industrial-grade operation in uncontrolled physical environments like outdoor access gates. |
| Tuning Capacitance | 82 pF ±10% between AC1–AC2 - eliminates need for external capacitor; enables single-coil antenna integration in thin RFID tags. |
Pinout & Package
AT88SC1616CRF-MY1 is supplied in the MY1 wafer-level die format (150 mm diameter, 6 mil thickness), intended for embedding into custom epoxy-glass or laminated RFID inlays. It features two RF terminals only: AC1 and AC2 - no VDD, VSS, or digital I/O pins. Power and data are fully coupled wirelessly via the antenna connected across AC1–AC2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | RF Antenna Terminal 1 | Connects to one end of external coil antenna; forms resonant LC tank with internal 82 pF capacitance. |
| AC2 | RF Antenna Terminal 2 | Connects to other end of external coil antenna; completes RF coupling path for power harvesting and half-duplex data exchange. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 14443-3 Type B Anticollision | Enables reliable multi-card polling in dense reader fields using Slot-MARKER protocol - critical for transit fare collection systems. |
| Per-Zone Access Control | Each of 16 user zones supports independent password sets, key selection, and read/write/encrypt permissions - allows secure multi-application card personalization. |
| Anti-Tearing Recovery | Automatically restores data integrity after power loss during write by buffering then committing - prevents corruption in mobile credential use cases. |
| Transport Password Protection | Hard-coded $50 44 72 secure code required to unlock configuration memory - prevents unauthorized personalization of security parameters. |
| OTP Security Fuses | Three sequenced fuses (module/card manufacturer/issuer) permanently lock configuration segments - enforces secure supply chain personalization hierarchy. |
Applications
| Physical Access Control Card | Secure Transit Fare Media |
|---|---|
|

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 ISO/IEC 14443-3 Type A only; 2 Kbyte NFC Forum Tag Type 4; no built-in tuning capacitor. | Limited to Type A infrastructure; requires external matching network; lacks CryptoRF's 64-bit mutual authentication and anti-tearing. | Select when NFC smartphone compatibility is primary and cryptographic strength is secondary to cost and simplicity. |
| Infineon SLE 78CLXXM | 13.56 MHz dual-interface (contact + contactless); 128 KB EEPROM; JavaCard OS support; requires external power for contact mode. | Supports complex applets and PKI; higher memory and processing overhead; larger footprint and higher cost than AT88SC1616CRF-MY1. | Select when multi-application JavaCard execution or contact fallback is required - not for pure low-cost secure RF memory. |
Compared with NT3H2211W0FHKH and SLE 78CLXXM, the AT88SC1616CRF-MY1 offers optimal balance of ISO Type B interoperability, hardware-enforced zone security, and wafer-level embeddability - making it uniquely suited for high-volume, tamper-aware RFID inlays where cryptographic assurance outweighs NFC smartphone-read capability or microprocessor flexibility.

FAQ
What is the operating temperature range specified for the AT88SC1616CRF-MY1?
The AT88SC1616CRF-MY1 is rated for −25°C to +85°C operation, meeting industrial environmental requirements. This range is explicitly confirmed in the Atmel-5026GS datasheet summary under "Reliability" and "Ordering Information", and applies to the MY1 wafer variant as part of the industrial temperature grade designation.
Does the AT88SC1616CRF-MY1 support ISO/IEC 14443 Type A communication?
No, the AT88SC1616CRF-MY1 is compliant only with ISO/IEC 14443-2 and -3 Type B. While its RF interface is tolerant of incidental Type A signal exposure (will not latch up or be damaged), it does not respond to Type A commands or participate in Type A anticollision - confirmed in Section 3.3 "Type A Tolerance" of the datasheet summary.
What is the transport password required to access configuration memory on the AT88SC1616CRF-MY1?
The transport password for AT88SC1616CRF-MY1 is fixed at $50 44 72 (hexadecimal), as documented in Section 7.7 "Transport Password" of the datasheet summary. This secure code must be presented via the Check Password command before any configuration memory programming or read operations are permitted.
How is memory organized in the AT88SC1616CRF-MY1, and what are the zone sizes?
The AT88SC1616CRF-MY1 organizes its 16 kilobits of user memory into sixteen 128-byte zones (each 1-Kbit), as stated in the device description and Table 4-1 "Memory Map". Each zone supports independent access rights, passwords, and encryption keys - enabling true multi-application data segregation within a single IC.
Is the AT88SC1616CRF-MY1 pin-compatible with other variants like AT88SC1616CRF-MX1 or AT88SC1616CRF-MVA1?
No - AT88SC1616CRF-MY1 is a bare die (6 mil wafer, 150 mm diameter), while MX1 and MVA1 are pre-packaged epoxy-glass RFID tags with different mechanical footprints and tape formats. The MY1 has no leadframe or molded package; its AC1/AC2 terminals are wire-bond pads, making it incompatible with surface-mount assembly processes used for MX1/MVA1.
