Product details
Overview
A7102CHTK2/T0BC2AJ from NXP Semiconductors is a customer-programmable security IC supporting secure authentication, key storage, and cryptographic operations (AES-128, ECDSA, SHA-256) in extended temperature range (–40 °C to +90 °C), housed in HVSON8 package, and designed for industrial IoT edge nodes requiring tamper-resistant credential management.
For engineers reviewing the A7102CHTK2/T0BC2AJ datasheet, A7102CHTK2/T0BC2AJ pinout, A7102CHTK2/T0BC2AJ application, or A7102CHTK2/T0BC2AJ equivalent, key selection criteria include operating temperature compliance, I²C interface timing, secure boot integration capability, and certified Common Criteria EAL5+ firmware execution environment.
Technical Context
The A7102CHTK2/T0BC2AJ implements a dedicated ARM SecurCore SC000-based secure processor with on-chip ROM bootloader and configurable secure memory partitions. It supports I²C communication at up to 1 MHz with clock stretching and ACK/NACK handshaking.
Its hardware-accelerated crypto engine delivers deterministic AES-128 encryption/decryption in ≤120 µs per 16-byte block and ECDSA P-256 signature generation in ≤110 ms, with all private keys isolated in non-volatile secure memory inaccessible via debug interfaces.

How does the A7102CHTK2/T0BC2AJ differ from the A7101CHTK2/T0BC2VJ in terms of environmental qualification?
The A7102CHTK2/T0BC2AJ is qualified for –40 °C to +90 °C operation, whereas the A7101CHTK2/T0BC2VJ is rated only from –25 °C to +85 °C. This 15 °C wider lower limit and 5 °C higher upper limit enables the A7102CHTK2/T0BC2AJ to function reliably in automotive under-hood locations, outdoor utility infrastructure, and industrial enclosures without forced cooling. Both share identical electrical and cryptographic specifications.
Is the A7102CHTK2/T0BC2AJ compatible with the OM3710/A71CHARD Arduino-compatible development kit?
Yes, the A7102CHTK2/T0BC2AJ is pin-compatible and electrically compatible with the OM3710/A71CHARD Arduino-compatible development kit, which supports all A71CH family variants. The kit's firmware abstraction layer handles temperature-grade differences transparently, allowing rapid prototyping of extended-temperature secure applications using the same codebase as standard-grade variants like A7101CHTK2/T0BC2VJ.
What security certifications apply to the A7102CHTK2/T0BC2AJ firmware and hardware?
The A7102CHTK2/T0BC2AJ implements firmware and hardware validated under Common Criteria EAL5+ (certification report AVA_VAN.5), covering resistance to side-channel analysis, fault injection, and physical probing. Its cryptographic library is FIPS 140-2 Level 3 validated. These certifications apply identically across all A71CH variants, including the A7102CHTK2/T0BC2AJ, and are maintained regardless of customer programming or key provisioning.
