For engineers reviewing the A7005CGHN1/T1AGBFJ datasheet, A7005CGHN1/T1AGBFJ pinout, A7005CGHN1/T1AGBFJ application, or A7005CGHN1/T1AGBFJ equivalent, key selection criteria include I2C slave operation at 100 kbit/s, −25 °C to +85 °C ambient rating, 76.4 kB EEPROM (MIFARE Config A), hardware-accelerated RSA-2048/ECC-320, and integrated TRNG compliant with AIS-31.

Technical Context

The A7005CGHN1/T1AGBFJ implements an asynchronous self-timed handshake architecture to resist timing-based side-channel attacks and integrates NXP's Secure Fetch Technology to protect ROM/RAM/EEPROM code fetches against laser and light fault injection. Its security stack includes active shielding, enhanced sensors (voltage, temperature, SFI), and glue logic for physical attack mitigation.

It executes Java Card 3.0.1 Classic and GlobalPlatform 2.1.1 on a hardened 80C51-derived core, with cryptographic coprocessors for PKI (RSA/ECC), triple-DES (2-/3-key), AES (128/192/256-bit), SHA-1/224/256, and MD5 - all operating within a 1.62 V to 5.5 V supply range and supporting wake-up from sleep mode via I2C communication.

FAQ

What is the primary security certification level achieved by the A7005CGHN1/T1AGBFJ?

The A7005CGHN1/T1AGBFJ is delivered with pre-programmed, die-specific keys and certificates generated in a Common Criteria-certified secure NXP internal environment. While the device itself supports EAL5+ evaluation, its default configuration meets Common Criteria EAL5 augmented with AVA_VAN.3 and ASE_TSP.1, enabling use in high-assurance applications like ePassports and banking cards.

Does the A7005CGHN1/T1AGBFJ support both contact and contactless interfaces simultaneously?

Yes, the A7005CGHN1/T1AGBFJ supports ISO/IEC 7816 contact interface and ISO/IEC 14443 A contactless interface concurrently. The contactless unit (CIU) operates independently from the I²C interface, allowing simultaneous host communication via I²C and RF field coupling - essential for hybrid secure element implementations in dual-mode readers.

Can the I²C slave address of the A7005CGHN1/T1AGBFJ be reconfigured after deployment?

Yes, the A7005CGHN1/T1AGBFJ supports I²C slave address reconfiguration through the JCOPX IO Configuration and Control API. This feature allows dynamic assignment of the 7-bit I²C address during runtime or personalization, enabling flexible multi-device addressing on shared buses without hardware modifications.

What is the maximum supported key length for elliptic curve cryptography in the A7005CGHN1/T1AGBFJ?

The A7005CGHN1/T1AGBFJ supports elliptic curve cryptography over GF(p) with key lengths up to 320 bits. This enables use of NIST P-256, P-384, and brainpoolP320r1 curves, satisfying FIPS 186-4 and ETSI TS 102 231 requirements for digital signatures and key agreement in high-security applications.

Is the A7005CGHN1/T1AGBFJ pin-compatible with other members of the A700x family in HVQFN32 packaging?

Yes, all A700x family variants in HVQFN32 (SOT617-1) packaging - including A7001, A7002, A7003, A7004, A7005, and A7006 - share identical pinout and mechanical footprint. This allows hardware design reuse across temperature grades and interface configurations, provided software and personalization match the selected variant's feature set.
