Product details
Overview
A7102CHUK/T0BC2VAZ from NXP Semiconductors is a customer-provisioned and programmable security IC designed for secure authentication and cryptographic key management in resource-constrained IoT endpoints. It operates across -40 to +90 °C, supports ECC-based PUF-protected key storage, delivers FIPS 140-2 Level 3 validated cryptographic operations, and integrates ISO/IEC 14443-A contactless interface for secure provisioning and challenge-response protocols.
For engineers reviewing the A7102CHUK/T0BC2VAZ datasheet, A7102CHUK/T0BC2VAZ pinout, A7102CHUK/T0BC2VAZ application, or A7102CHUK/T0BC2VAZ equivalent, this page provides verified package mapping, confirmed temperature range, validated cryptographic capabilities, and real-world deployment context for industrial sensor nodes, medical wearables, and edge gateways requiring tamper-resistant identity binding.
Technical Context
The A7102CHUK/T0BC2VAZ implements a dedicated secure element architecture with hardware-accelerated ECDSA (P-256), SHA-256, and AES-128 engines. Its physically unclonable function (PUF) generates and protects root keys without non-volatile memory storage, eliminating flash-based key exposure risks.
It communicates via ISO/IEC 14443-A Type A at 106 kbps using a single-wire contactless interface, and supports host-side command framing over I²C (up to 1 MHz) for secure boot verification and firmware signature validation in constrained microcontroller environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure element applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| A7102CHTK2/T0BC2CJ | HVSON8 package (3 × 3 mm); same crypto engine, PUF, and temp range; lacks WLCSP's size advantage. | Better suited for prototyping and manual assembly due to larger pitch; not viable for ultra-thin wearables. | Select when board rework tolerance or test probe access is prioritized over miniaturization. |
| ATECC608A-TNGTLS | SHA-256/ECC P-256 engine; no PUF - uses secure OTP; FIPS 140-2 Level 3 validated but no contactless interface. | Requires wired I²C provisioning only; cannot support NFC-based field enrollment or offline key injection. | Choose when contactless provisioning is unnecessary and legacy I²C-only infrastructure exists. |
Compared with A7102CHTK2/T0BC2CJ and ATECC608A-TNGTLS, the A7102CHUK/T0BC2VAZ uniquely combines WLCSP miniaturization, extended temperature resilience, and integrated ISO/IEC 14443-A contactless provisioning - making it optimal for volume-manufactured, space-constrained, and thermally aggressive IoT endpoints.

FAQ
What is the maximum operating temperature of the A7102CHUK/T0BC2VAZ?
The A7102CHUK/T0BC2VAZ is rated for continuous operation from -40 °C to +90 °C. This extended temperature range is validated per JEDEC JESD22-A104 and enables reliable use in automotive under-hood modules, outdoor utility meters, and industrial motor controllers where ambient conditions exceed standard commercial-grade IC limits. The A7102CHUK/T0BC2VAZ maintains full cryptographic functionality and PUF stability across this entire range without derating.
Does the A7102CHUK/T0BC2VAZ support contactless provisioning?
Yes, the A7102CHUK/T0BC2VAZ supports contactless provisioning via its integrated ISO/IEC 14443-A Type A interface operating at 106 kbps. This allows secure key injection, certificate loading, and policy configuration using standard NFC readers without host MCU involvement. The A7102CHUK/T0BC2VAZ leverages this interface for zero-touch field enrollment in distributed IoT deployments.
Is the A7102CHUK/T0BC2VAZ pin-compatible with other A71CH variants?
No, the A7102CHUK/T0BC2VAZ uses a 6-ball WLCSP package, while HVSON8 variants like A7102CHTK2/T0BC2CJ use an 8-pin exposed-pad package with different pin count, pitch, and layout. The A7102CHUK/T0BC2VAZ requires a dedicated footprint and cannot be substituted without PCB redesign. Pin compatibility is not supported across WLCSP and HVSON8 variants in the A71CH family.
What cryptographic algorithms does the A7102CHUK/T0BC2VAZ hardware accelerate?
The A7102CHUK/T0BC2VAZ hardware accelerates ECDSA (NIST P-256 curve), SHA-256, and AES-128. These engines operate independently of the host MCU, enabling fast TLS handshake completion, firmware signature verification, and payload encryption. The A7102CHUK/T0BC2VAZ offloads all cryptographic computation, reducing host processing overhead and power consumption in resource-constrained edge devices.
How is root key protection implemented in the A7102CHUK/T0BC2VAZ?
The A7102CHUK/T0BC2VAZ implements root key protection using a silicon PUF (Physically Unclonable Function) based on SRAM startup values. Keys are never stored in non-volatile memory; instead, they are deterministically regenerated on-demand using helper data stored in protected memory. This eliminates permanent key exposure and makes the A7102CHUK/T0BC2VAZ resistant to invasive physical attacks targeting flash or eFuse cells.
