Product details
Overview
P5DF081X0/T1AD2060 from NXP Semiconductors is a secure access module (SAM) designed for integration with RC52X contactless reader ICs to enable cryptographic authentication, secure key storage, and tamper-resistant communication in smart card infrastructure. It supports TDEA, AES-128/192, RSA up to 2048-bit, MIFARE Crypto-1, and operates at ISO/IEC 7816 Class A (5 V) or Class B (3 V) supply. It delivers secure host-to-SAM and SAM-to-PICC messaging for public transport fare collection systems.
For engineers reviewing the P5DF081X0/T1AD2060 datasheet, P5DF081X0/T1AD2060 pinout, P5DF081X0/T1AD2060 application, or P5DF081X0/T1AD2060 equivalent, this page provides verified technical context, validated pin functions for PCM1.1 module format, confirmed cryptographic capabilities per NXP Rev. 3.1 short data sheet, and real-world interoperability with MIFARE DESFire EV1 and MIFARE Plus cards.
Technical Context
The P5DF081X0/T1AD2060 implements a dual-mode security architecture: MIFARE SAM AV1 compatibility mode for legacy system support and full MIFARE SAM AV2 mode enabling PKI-based RSA operations, key classification (Host/PICC/OfflineChange/OfflineCrypto), and three-tier SAM–host protection (Plain/MAC/Full). Its dedicated I²C interface pins (IO1, IO2, IO3) are wired for direct connection to RC52X readers using the "X-feature" architecture.
It integrates an enhanced public-key coprocessor (RSA), AES and Triple-DES coprocessors, 80 kB EEPROM, 264 kB ROM, 7.68 kB program RAM, TRNG, and ISO/IEC 7816-compliant contact interface with cold/warm reset ATR toggling. The device enforces key usage counters, key diversification, and locked UID (7-byte) with manufacturer-programmed permanence.

Key Features
| Feature | Design Value |
|---|---|
| PKI-enabled RSA operations | Supports RSAES-OAEP encryption/decryption and RSASSA-PSS signature generation/verification - enables backend-signed credential issuance and offline verification |
| Four-key-class architecture | Host, PICC, OfflineChange, and OfflineCrypto key classes enforce strict usage boundaries - prevents misuse of card-authentication keys for host-channel protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure access module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P5DF081X0/T1AR1070 | Different X-feature interface targeting RC663 readers instead of RC52X; identical crypto engine, memory, and package options | Requires RC663-based reader design; not electrically compatible with RC52X hardware due to I²C signal mapping divergence | Select only when integrating with NXP RC663 reader ICs; same firmware and key provisioning workflow applies |
| P5DF081HN/T1AD2060 | HVQFN32 package (5 × 5 × 0.85 mm) vs. PCM1.1 module; identical functionality and pinout mapping but different mechanical form factor and thermal profile | Suitable for space-constrained PCB layouts where surface-mount integration is preferred over module socketing | Choose for embedded reader designs requiring direct SMT assembly; requires revalidation of ISO/IEC 7816 signal integrity at 1.5 Mbit/s |
Compared with P5DF081X0/T1AD2060, the T1AR1070 variant shifts reader interface compatibility from RC52X to RC663 while preserving all cryptographic capabilities, whereas the HVQFN-packaged P5DF081HN/T1AD2060 maintains identical electrical behavior but replaces the contact module with a surface-mount IC for board-level integration - both require no changes to SAM firmware or key management logic.

FAQ
What is the primary interface standard supported by the P5DF081X0/T1AD2060?
The P5DF081X0/T1AD2060 implements a fully compliant ISO/IEC 7816-3 contact interface with T=1 protocol support and negotiable bit rates up to 1.5 Mbit/s. Its PCM1.1 module format uses standard ISO pads C1–C8, with C6 and C8 repurposed for I²C communication to RC52X readers under the "X-feature" architecture - a deviation from pure ISO compliance required for accelerated reader–SAM interaction. This interface is validated in NXP's P5DF081_SDS Rev. 3.1.
Does the P5DF081X0/T1AD2060 support RSA cryptography?
Yes, the P5DF081X0/T1AD2060 supports RSA cryptography exclusively in MIFARE SAM AV2 mode, not in AV1 compatibility mode. It implements RSAES-OAEP encryption/decryption and RSASSA-PSS signature generation/verification for key sizes from 256-bit to 2048-bit. The device stores up to three RSA key entries (two private/public pairs and one public key) in its PKI Key Storage Table (PKI_KST), as specified in Section 8.4.4.2 of the official short data sheet.
How many symmetric keys can the P5DF081X0/T1AD2060 store, and what types are supported?
The P5DF081X0/T1AD2060 stores up to 128 symmetric key entries in its Key Storage Table (KST), supporting DES (56-bit), 2TDEA (112-bit), 3TDEA (168-bit), AES-128, AES-192, and MIFARE Classic keys. Each entry accommodates three DES/2TDEA/AES-128 keys, two 3TDEA/AES-192 keys, or six MIFARE keys. Key versioning (00h–FFh) and usage counters (16 entries) are enforced per entry, as documented in Sections 8.4.3 and 8.4.6 of the P5DF081_SDS.
What is the function of the C6 and C8 pins on the P5DF081X0/T1AD2060 PCM1.1 module?
On the P5DF081X0/T1AD2060 PCM1.1 module, C6 (IO3) serves as the I²C clock output (SCLK) to the RC52X reader IC, and C8 (IO2) serves as the I²C data I/O (SDATA) line for bidirectional communication. These pins deviate from ISO/IEC 7816 pin assignments to enable the "X-feature" interface, allowing simultaneous SAM–host and SAM–reader communication. Their functionality is defined in Table 3 and Section 8.1.1 of the NXP P5DF081_SDS Rev. 3.1.
Can the P5DF081X0/T1AD2060 be used with RC663 readers?
No, the P5DF081X0/T1AD2060 is specifically designed for RC52X readers via its X-feature I²C interface (C6/C8 pins). For RC663 compatibility, NXP specifies the P5DF081X0/T1AR1070 variant, which uses identical cryptographic functionality but maps I²C signals to different pins optimized for RC663 timing and protocol handling. Interchanging these variants without hardware redesign will result in interface failure, as confirmed in Section 1 and Table 2 of the P5DF081_SDS.
