It operates across −40 °C to +90 °C and integrates hardware-accelerated cryptographic coprocessors for RSA-2048, ECC-320, AES-128/192/256, and triple-DES - deployed in e-passports, secure mobile identity, and embedded M2M authentication systems.

For engineers reviewing the A7002CGHN1/T1AG502 datasheet, A7002CGHN1/T1AG502 pinout, A7002CGHN1/T1AG502 application, or A7002CGHN1/T1AG502 equivalent, this page delivers verified electrical specs, package mapping, security architecture context, and real-world integration guidance for high-assurance embedded authentication design.

Technical Context

The A7002CGHN1/T1AG502 implements an asynchronous self-timed handshake architecture to resist timing-based side-channel attacks and integrates Secure Fetch Technology to protect ROM/RAM/EEPROM code fetches against laser and light fault injection. Its security stack includes active shielding, NXP glue logic, and >100 countermeasures validated under Common Criteria.

It executes JCOP 2.4.2 R1 compliant with Java Card 3.0.1 Classic and GlobalPlatform 2.1.1, supporting X.509 client authentication applets pre-installed in ROM. The device uses a 62 MHz internally generated CPU clock and supports wake-up from sleep mode via I²C communication - enabling low-power always-on secure identity in battery-constrained endpoints.

FAQ

What is the primary security certification level achieved by the A7002CGHN1/T1AG502?

The A7002CGHN1/T1AG502 is manufactured and provisioned in a Common Criteria-certified secure environment. While the short data sheet does not list its individual EAL rating, the A700x family leverages NXP's CC-certified security processes, including HSM-based key generation and die-specific certificate injection. Full certification details require access to the confidential full data sheet (Document Number 2066xx2) and associated evaluation reports under NDA.

Does the A7002CGHN1/T1AG502 support contactless interfaces like ISO/IEC 14443?

No, the A7002CGHN1/T1AG502 does not support ISO/IEC 14443 or any contactless interface. Per the A700x family feature table and block diagram notes, contactless functionality is exclusive to A7005 and A7006 variants. The A7002CGHN1/T1AG502 is strictly an I²C-only secure MCU with optional ISO/IEC 7816 omitted - confirmed by its product type designation and ordering information in Table 4.

Can the I²C slave address of the A7002CGHN1/T1AG502 be changed after deployment?

Yes, the A7002CGHN1/T1AG502 supports dynamic I²C slave address reconfiguration via the JCOPX IO Configuration and Control API. This capability - documented in Section 1.5 and Table 5 - allows runtime adjustment of the I²C address without requiring applet reload or device reset, enabling flexible multi-device addressing on shared buses in field-deployed systems.

What is the endurance and retention specification for the EEPROM in the A7002CGHN1/T1AG502?

The A7002CGHN1/T1AG502 provides 76.4 kB of EEPROM with minimum write endurance of 500,000 cycles and minimum data retention of 25 years at +55 °C ambient - as specified in Table 2 (Quick reference data) and Section 2.1. These values are guaranteed across the full −40 °C to +90 °C operating range and apply to both application code and persistent data storage.

Is the A7002CGHN1/T1AG502 pin-compatible with other A700x family members in HVQFN32 packaging?

Yes, all A700x family members in HVQFN32 (SOT617-1) packaging - including A7001, A7002, A7003, A7004, A7005, and A7006 - share identical pinouts and mechanical footprints. This allows hardware design reuse across temperature grades and interface options, though functional differences (e.g., presence of ISO/IEC 7816 pins) are managed via internal configuration rather than pin assignment.
