Product details
Overview
A7101CHUK/T0BC2HAZ from NXP Semiconductors is a customer-programmable secure element IC implementing ECDSA P-256 signature verification, AES-128 encryption, and SHA-256 hashing in a WLCSP package. It operates over -25 °C to +85 °C and supports I²C interface at 1 MHz for secure boot authentication in IoT edge nodes.
For engineers reviewing the A7101CHUK/T0BC2HAZ datasheet, A7101CHUK/T0BC2HAZ pinout, A7101CHUK/T0BC2HAZ application, or A7101CHUK/T0BC2HAZ equivalent, key selection criteria include WLCSP footprint compatibility, I²C timing compliance, cryptographic algorithm support, and secure provisioning workflow integration.
Technical Context
The A7101CHUK/T0BC2HAZ integrates a dedicated cryptographic co-processor with hardware-accelerated ECDSA, AES, and SHA operations, isolating key storage from host MCU memory space. It uses a hardened secure boot ROM and supports secure firmware update via authenticated command sequences.
Its I²C interface complies with SMBus 2.0 timing, includes clock stretching support, and enforces strict address matching (0x48) with ACK/NACK protocol enforcement. The device implements tamper-resistant non-volatile memory with write-protection lock bits and secure erase functionality.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| A7101CHTK2/T0BC2VJ | HVSON8 package (3.0 × 3.0 mm), same crypto engines and temp range - larger footprint, easier rework | Preferred where board space allows and hand-soldering or optical inspection is required | Select when WLCSP assembly capability is unavailable or thermal cycling reliability testing favors HVSON |
| A7102CHUK/T0BC2VAZ | Same WLCSP package but extended temperature range (-40 °C to +90 °C), identical crypto features | Required for outdoor or under-hood automotive telemetry applications exceeding +85 °C ambient | Choose only if operating environment exceeds A7101CHUK/T0BC2HAZ's +85 °C upper limit |
Compared with A7101CHUK/T0BC2HAZ, the HVSON8 variant trades miniaturization for assembly flexibility, while the A7102CHUK/T0BC2VAZ extends thermal envelope without altering security architecture or interface behavior.

FAQ
What is the primary cryptographic function supported by the A7101CHUK/T0BC2HAZ?
The A7101CHUK/T0BC2HAZ provides hardware-accelerated ECDSA P-256 signature verification, AES-128 encryption, and SHA-256 hashing. These functions are implemented in dedicated logic with isolated key storage, enabling deterministic execution times and resistance to software-based side-channel attacks. The A7101CHUK/T0BC2HAZ does not support RSA or ECC curves beyond P-256.
Does the A7101CHUK/T0BC2HAZ require external programming before use?
Yes, the A7101CHUK/T0BC2HAZ is customer-programmable and ships unprovisioned. Keys, certificates, and application policies must be loaded via its I²C interface using NXP's EdgeLock SE Provisioning Tool. The A7101CHUK/T0BC2HAZ supports secure provisioning workflows including key derivation, certificate chaining, and write-lock enforcement to prevent post-deployment modification.
Can the A7101CHUK/T0BC2HAZ operate with a 1.8 V host system?
Yes, the A7101CHUK/T0BC2HAZ supports supply voltages from 1.71 V to 3.6 V, making it fully compatible with 1.8 V logic systems. Its I²C interface operates correctly at 1.8 V VDD, with SCL/SDA levels referenced to VDD and internal level-shifting ensuring reliable communication without external translators. This is verified across the full -25 °C to +85 °C operating range.
Is the A7101CHUK/T0BC2HAZ pin-compatible with other members of the A710xCH family?
No, the A7101CHUK/T0BC2HAZ uses a WLCSP-8 package with a unique 2.15 × 1.95 mm footprint and 0.4 mm ball pitch, while HVSON8 variants like A7101CHTK2/T0BC2VJ use a 3.0 × 3.0 mm body and 0.5 mm pitch. Pin assignments differ between packages; direct PCB replacement is not possible without layout revision. The A7101CHUK/T0BC2HAZ shares functional I²C interface behavior but not mechanical or electrical pinout compatibility.
What security certifications apply to the A7101CHUK/T0BC2HAZ?
The A7101CHUK/T0BC2HAZ is certified to Common Criteria EAL5+ (augmented) for secure elements and meets ISO/IEC 15408:2009 requirements. It also complies with FIPS 140-2 Level 3 physical security requirements for tamper resistance. These certifications cover the silicon, firmware, and secure boot ROM of the A7101CHUK/T0BC2HAZ and are documented in NXP's official certification reports issued by accredited laboratories.
