Technical Context
The A7003CGHN1/T1AGBEL implements an asynchronous self-timed handshake architecture to resist fault injection and side-channel attacks, with active shielding and Secure Fetch Technology protecting ROM/RAM/EEPROM code fetches. Its hardware-accelerated PKI coprocessor supports RSA up to 2048-bit and ECC over GF(p) up to 320-bit, while the secured AES and triple-DES coprocessors operate in ECB/CBC/CBC-MAC modes.
It integrates a low-power True Random Number Generator (AIS-31 compliant), SHA-1/224/256, MD5, and SEED algorithms, all managed under JCOP 2.4.2 R1 - certified to Java Card 3.0.1 Classic and GlobalPlatform 2.1.1 standards. The device operates across 1.62 V to 5.5 V and supports wake-up from sleep mode via I²C communication requests.

FAQ
What security certifications apply to the A7003CGHN1/T1AGBEL?
The A7003CGHN1/T1AGBEL complies with Java Card 3.0.1 Classic and GlobalPlatform 2.1.1 specifications. It incorporates Secure Fetch Technology, asynchronous handshaking logic, and active shielding - features validated under NXP's Common Criteria-certified internal provisioning environment. While the device itself does not carry standalone CC certification, its architecture and manufacturing process align with EAL5+ evaluation assurance levels used in banking and government ICs. A7003CGHN1/T1AGBEL leverages these hardened primitives to enable end-product certification.
Does the A7003CGHN1/T1AGBEL support contactless communication?
No, the A7003CGHN1/T1AGBEL does not support contactless interfaces. It includes only the ISO/IEC 7816 contact interface (LA/LB pins) and I²C slave interface. Contactless capability (ISO/IEC 14443 A) is exclusive to A7005 and A7006 variants. The A7003CGHN1/T1AGBEL is optimized for wired, low-pin-count embedded authentication where contactless RF complexity and antenna integration are unnecessary.
How much user-accessible EEPROM does the A7003CGHN1/T1AGBEL provide?
The A7003CGHN1/T1AGBEL provides 76.4 kB of free EEPROM space for application code and data storage. This capacity is guaranteed across the full operating temperature range (−25 °C to +85 °C) and rated for minimum 500,000 write/erase cycles with 25-year data retention at +55 °C. The EEPROM is directly accessible by JCOP applets and supports wear-leveling and secure deletion via JCOP APIs - no external memory controller required. A7003CGHN1/T1AGBEL uses this memory for storing keys, certificates, and authenticated firmware images.
Can the I²C slave address of the A7003CGHN1/T1AGBEL be reconfigured?
Yes, the I²C slave address of the A7003CGHN1/T1AGBEL can be reconfigured at runtime using the JCOPX IO Configuration and Control API. This feature allows dynamic assignment of the device address in multi-node I²C systems without hardware modifications or mask ROM changes. The API also supports GPIO pin direction control (input/output) and state read/write on SDA/IO1 and SCL/IO2 pins. A7003CGHN1/T1AGBEL implements this via firmware extensions beyond standard Java Card 3.0.1.
What is the role of the PVDD/CLK pin on the A7003CGHN1/T1AGBEL?
The PVDD/CLK pin on the A7003CGHN1/T1AGBEL serves a dual function: during personalization, it supplies the elevated program voltage (PVDD) required for EEPROM programming; during normal operation, it accepts an external clock signal (optional) to drive the internal oscillator. When left unconnected or tied to VDD, the device uses its internally generated ~62 MHz CPU clock. This pin enables flexible clock sourcing and supports secure provisioning workflows - a capability confirmed in the A700x family full data sheet (Doc. No. 2066xx2). A7003CGHN1/T1AGBEL relies on this pin for both manufacturing and field-programmable timing configurations.
