Product details
Overview
AT88SC3216CRF-MX1 from Microchip Technology (formerly Atmel) is a contactless 13.56 MHz CryptoRF EEPROM memory IC embedded in an epoxy-glass RFID tag, delivering 32 kilobits of user memory across 16 zones, ISO/IEC 14443-2 & -3 Type B compliance, and 64-bit mutual authentication for secure data storage in physical access cards and payment tokens.
For engineers reviewing the AT88SC3216CRF-MX1 datasheet, AT88SC3216CRF-MX1 pinout, AT88SC3216CRF-MX1 application, or AT88SC3216CRF-MX1 equivalent, this page provides verified package dimensions, RF interface timing, security mode transitions, zone-level access control, and tamper-resistant write integrity - all confirmed for the MX1 13 mm × 13 mm epoxy-glass tag variant.
Technical Context
The AT88SC3216CRF-MX1 implements a fully integrated RF front-end with on-die 82 pF tuning capacitance between AC1 and AC2 terminals, enabling operation with only an external coil antenna. It uses half-duplex communication at 106 kbit/s with 2-byte CRC_B error detection and supports ISO/IEC 14443-3 Slot-MARKER anticollision for multi-card environments.
Security execution relies on four independent key sets, eight 24-bit password groups, and three OTP security fuses (module, card manufacturer, issuer). Memory access is enforced per-zone via programmable AFI, read/write passwords, and anti-tearing recovery - all validated during power-on reset and maintained across RF field interruptions.

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 | 1 Kbyte NFC Forum Type 2 Tag with NDEF support; no mutual authentication or zone-level crypto keys | Limited to simple data storage (URLs, text); lacks AFI, anti-tearing, or transport password features | Select when NFC smartphone compatibility and low-cost NDEF encoding are primary; not suitable for high-security credentialing |
| Infineon SLE78CLFX2040P | Smart card IC with ARM SecurCore SC000 CPU, JavaCard OS, and full ISO/IEC 7816-4 APDU stack | Requires microprocessor-based firmware development and external power; higher BOM cost and design complexity | Select when application requires dynamic applet loading, PKI certificate management, or dual-interface (contact + contactless) operation |
Compared with NT3H2211W0FHKH and SLE78CLFX2040P, the AT88SC3216CRF-MX1 delivers hardware-enforced cryptographic zoning and anti-tearing without firmware overhead - making it optimal for fixed-function, high-volume secure RFID tags where deterministic behavior and minimal host-side logic are critical.

FAQ
What is the exact package form factor of the AT88SC3216CRF-MX1?
The AT88SC3216CRF-MX1 is supplied as a 13 mm × 13 mm square epoxy-glass RFID tag with gold-plated AC1 and AC2 terminals, mounted on 35 mm tape. Its mechanical drawing confirms no exposed silicon die or conventional IC package - it is a fully encapsulated passive RF tag optimized for embedding into PVC or polycarbonate cards.
Does the AT88SC3216CRF-MX1 require an external tuning capacitor?
No, the AT88SC3216CRF-MX1 integrates an 82 pF ±10% capacitor between AC1 and AC2 terminals. This eliminates the need for external capacitors in antenna matching circuits, simplifying PCB or inlay design and improving production yield for RFID tag manufacturers using the AT88SC3216CRF-MX1.
How does the anti-tearing function operate in the AT88SC3216CRF-MX1?
The AT88SC3216CRF-MX1 implements anti-tearing by writing data first to a buffer zone in EEPROM before committing it to the target address. If power is lost during the second write, the device recovers the original data from the buffer at next power-up - ensuring atomicity for critical operations like balance updates or access log entries stored in the AT88SC3216CRF-MX1.
What is the default transport password for configuring the AT88SC3216CRF-MX1?
The default transport password for accessing the configuration memory of the AT88SC3216CRF-MX1 is hexadecimal $6078AF. This secure code must be presented via the Check Password command before programming AFI, passwords, keys, or security fuses - preventing unauthorized personalization of the AT88SC3216CRF-MX1 during manufacturing or issuance.
Is the AT88SC3216CRF-MX1 compatible with ISO/IEC 14443-3 Type A readers?
The AT88SC3216CRF-MX1 is compliant only with ISO/IEC 14443-2 and -3 Type B. It tolerates exposure to Type A signals without damage or lock-up but does not respond to them. Therefore, the AT88SC3216CRF-MX1 cannot interoperate with Type A readers - its anticollision, frame formatting, and modulation schemes are strictly Type B-defined.
