Product details
Overview
A7002CIHN1/T1AGBEL from NXP Semiconductors is a tamper-resistant secure authentication microcontroller featuring the dedicated security-hardened MX51CPU core, 76.4 kB EEPROM, JCOP 2.4.2 R1 Java Card OS, and hardware-accelerated cryptographic coprocessors (RSA-2048, ECC-320, AES-128/192/256, triple-DES). It operates from −40 °C to +90 °C and supports I²C slave interface at 100 kbit/s - deployed in embedded secure elements for mobile device authentication and trusted identity management.
For engineers reviewing the A7002CIHN1/T1AGBEL datasheet, A7002CIHN1/T1AGBEL pinout, A7002CIHN1/T1AGBEL application, or A7002CIHN1/T1AGBEL equivalent, key selection considerations include extended temperature operation, die-specific X.509 certificate pre-provisioning, ISO/IEC 7816 and 14443 interface options (not present on this variant), JCOP 2.4.2 R1 compliance, and hardware TRNG with AIS-31 certification.
Technical Context
The A7002CIHN1/T1AGBEL 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 Java Card 3.0.1 Classic and GlobalPlatform 2.1.1 applications via a hardened JCOP 2.4.2 R1 OS with pre-installed X.509 client authentication applet, supporting APDU-based host interaction over I²C only - no contact or contactless interfaces are enabled on this specific variant per family documentation.

FAQ
What is the maximum I²C clock frequency supported by A7002CIHN1/T1AGBEL?
A7002CIHN1/T1AGBEL supports I²C slave operation at up to 100 kbit/s - compliant with standard-mode I²C. It does not support fast-mode (400 kbit/s) or high-speed mode. The interface is strictly slave-only; no master functionality is implemented. This speed is optimized for secure, low-power communication with host MCUs in authentication-critical systems where deterministic timing and side-channel resilience take priority over raw throughput.
Does A7002CIHN1/T1AGBEL include ISO/IEC 7816 or ISO/IEC 14443 interfaces?
No, A7002CIHN1/T1AGBEL does not include ISO/IEC 7816 or ISO/IEC 14443 interfaces. Per the A700x family feature table and block diagram notes, those interfaces are only available on A7003/A7004 (7816) and A7005/A7006 (7816 + 14443). A7002CIHN1/T1AGBEL is I²C-only, making it ideal for host-attached secure element designs without contact or contactless smart card requirements.
What cryptographic algorithms are hardware-accelerated in A7002CIHN1/T1AGBEL?
A7002CIHN1/T1AGBEL includes dedicated hardware coprocessors for RSA up to 2048-bit keys, ECC over GF(p) up to 320-bit keys, AES with 128/192/256-bit keys, and 2-key/3-key triple-DES. It also integrates a hardware TRNG compliant with AIS-31, SHA-1/224/256, MD5, SEED, and CRC calculation units - all implemented with side-channel attack countermeasures including DPA/SPA resistance.
Is JCOP 2.4.2 R1 pre-installed on A7002CIHN1/T1AGBEL, and what applets are included?
Yes, A7002CIHN1/T1AGBEL ships with JCOP 2.4.2 R1 pre-installed in ROM. It includes a factory-preloaded X.509 certificate-based client authentication application, enabling immediate TLS client certificate authentication over I²C. No additional applet loading is required for basic PKI operations. Custom applets may be loaded post-personalization using GlobalPlatform-compliant secure channels.
What is the endurance and data retention specification for the EEPROM in A7002CIHN1/T1AGBEL?
The EEPROM in A7002CIHN1/T1AGBEL guarantees minimum 500,000 write/erase cycles and 25 years of data retention at +55 °C ambient temperature. These values are specified under all operating conditions per the A700x family quick reference data. The EEPROM is used for both application code storage and persistent data, and its reliability is reinforced by built-in wear leveling and error correction managed by the JCOP OS.
