Product details
Overview
A7102CGHN1/T0B04EL from NXP Semiconductors is a Plug & Trust Secure Element IC implementing Java Card OS and preloaded IoT security applet, supporting ECC NIST P-256 key pairs, ECDSA signature, ECDH key agreement, and SCP03 secure channel - deployed in industrial IoT gateways for device-to-cloud authentication.
For engineers reviewing the A7102CGHN1/T0B04EL datasheet, A7102CGHN1/T0B04EL pinout, A7102CGHN1/T0B04EL application, or A7102CGHN1/T0B04EL equivalent, this page delivers verified package mapping (WLCSP12), I²C slave interface details (400 kbit/s Fast-mode, 7-bit address 0x48/0x49), power modes (10 µA deep sleep), cryptographic capabilities (4× ECC P-256 key pairs), and real-world use-case alignment with AWS-compliant connectivity and anti-counterfeiting.
Technical Context
The A7102CGHN1/T0B04EL operates as an autonomous secure co-processor using a dedicated MX51 security CPU and on-chip Java Card OS, isolating credential storage from host MCU access. It implements Smartcard I²C (SCI²C) protocol over standard I²C physical layer, enforcing strict APDU-based command flow per ISO/IEC 7816-4.
Its security architecture integrates hardware-level countermeasures against SPA/DPA, active shielding, glitch detection, and monotonic counters (2×32-bit), with all cryptographic operations (ECDSA, ECDH, HMAC-SHA256, HKDF) executed internally - no private key exposure to host. Memory includes EEPROM rated for 500,000 cycles and 25-year data retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ECC Support | NIST P-256 curve only; enables FIPS 186-4–compliant signatures and key agreement in constrained devices. |
| I²C Interface | Slave mode, 400 kbit/s Fast-mode; uses SCI²C protocol with 7-bit addresses 0x48 (default) and 0x49 (alternate). |
| Operating Temp | −40 °C to +90 °C; validated for industrial edge nodes including IP cameras and home gateways. |
| Power Consumption | 10 µA deep sleep current; enables battery-backed security in always-on IoT endpoints without compromising longevity. |
| Memory Endurance | 500,000 EEPROM write cycles; supports field-updatable credentials and long-term provisioning in production firmware. |
| Credential Storage | 4× protected ECC key pairs, 3× public keys, 8× 128-bit symmetric secrets, 2× monotonic counters - all accessible only via authenticated secure channel. |
Pinout & Package
Package: WLCSP12 (wafer-level chip-scale package, 0.5 mm ball pitch, 12-bump layout). Thermal and mechanical footprint matches JEDEC MO-257.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Not connected | No internal connection; usable for PCB routing or grounding stubs. |
| A2 | VSS | Ground reference for all digital and analog blocks; must be low-impedance to suppress noise during crypto operations. |
| A3 | I²C_SCL | Open-drain clock input; requires external pull-up; timing-critical for 400 kHz Fast-mode compliance. |
| A4 | I²C_SDA | Open-drain bidirectional data line; shares same pull-up as SCL; handles SCI²C frame encapsulation. |
| B2 | VCC | Single supply input (1.62–1.98 V or 2.5–3.6 V); powers core logic, crypto accelerators, and EEPROM controller. |
| B4 | IF1 | I²C address selection; high = 0x49 (7-bit), low = 0x48; sampled at power-on-reset for automatic address configuration. |
| C3 | RST_N | Active-low reset; ≥500 µs pulse enters deep sleep; falling edge on SDA wakes from sleep - no external reset controller needed. |
| C4 | IF0 | Interface activation; must be held high during power-on-reset to enable I²C interface; tied to VCC in most designs. |
Key Features
| Feature | Design Value |
|---|---|
| SCP03 Secure Channel | Enables authenticated, encrypted communication between host and A7102CGHN1/T0B04EL using AES-128 keys - required for GP-compliant provisioning. |
| Transport Lock | Immutable lock state prevents unauthorized reprogramming after deployment - critical for anti-counterfeiting in supply chain handoff. |
| HKDF Key Derivation | Supports Extract-and-Expand or Expand-only modes using symmetric secrets as entropy source - enables hierarchical key derivation for multi-tier cloud architectures. |
| Monotonic Counters | Two independent 32-bit upcounters with protected access - used for firmware update attestation and tamper-evident logging. |
| OTP Credential Freezing | One-time programmable freeze of keys/public certificates post-provisioning - enforces immutable root-of-trust in certified devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure element applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATECC608A-TFLXT | Uses SHA-256 + ECC P-256 but lacks SCP03 support; relies on custom command set instead of GlobalPlatform. | Targeted at cost-sensitive consumer IoT; not certified for banking-grade provisioning workflows. | Select when budget constraints outweigh need for GP-compliant secure channel and transport lock features. |
| SLB9670VQ2.0 | TPM 2.0-compliant; supports RSA-2048 and PCR registers; larger footprint (QFN32); requires SPI interface. | Designed for PC/server BIOS integrity; over-specified for embedded sensor nodes with space/power limits. | Select only if full TPM 2.0 stack integration and PCR-based attestation are mandatory for system certification. |
Compared with ATECC608A-TFLXT and SLB9670VQ2.0, the A7102CGHN1/T0B04EL uniquely balances industrial temperature range (−40°C to +90°C), WLCSP12 size, SCP03 compliance, and preloaded IoT applet - making it optimal for space-constrained, cloud-connected edge devices requiring out-of-box security.

FAQ
What is the primary security function of the A7102CGHN1/T0B04EL?
The A7102CGHN1/T0B04EL serves as a hardware-rooted secure element that provides cryptographic key generation, storage, and usage isolation via its integrated Java Card OS and IoT applet. It performs ECDSA signing, ECDH key agreement, and SCP03-secured communication - ensuring private keys never leave the die. This makes A7102CGHN1/T0B04EL ideal for establishing immutable device identity in cloud-connected systems.
Does the A7102CGHN1/T0B04EL support both 1.8 V and 3.3 V operation?
Yes, the A7102CGHN1/T0B04EL supports dual-voltage operation: 1.62–1.98 V (1V8 mode) and 2.5–3.6 V (3V3 mode), with corresponding current consumption profiles. In 1V8 mode, typical active current is 2.45 mA (no coprocessor) and 7.5 mA (ECC active); in 3V3 mode, it is 7.0 mA and 15.1 mA respectively. This flexibility allows A7102CGHN1/T0B04EL to integrate seamlessly into battery-powered and mains-powered designs.
How does the A7102CGHN1/T0B04EL handle I²C address selection?
The A7102CGHN1/T0B04EL uses pins IF0 and IF1 sampled at power-on-reset to determine I²C address: IF0 must be high to enable the interface, and IF1 selects between 7-bit addresses 0x48 (IF1 low) and 0x49 (IF1 high). This dual-address capability allows multiple A7102CGHN1/T0B04EL devices on the same bus - essential for modular systems where each subsystem requires independent secure element control.
What packaging option corresponds to the A7102CGHN1/T0B04EL part number?
The suffix "HN1" in A7102CGHN1/T0B04EL explicitly denotes WLCSP12 package per NXP's naming convention (Table 1). This 0.5 mm pitch wafer-level chip-scale package measures ~1.6 × 1.6 mm and is optimized for space-constrained applications like IP cameras and wearable health monitors. Unlike HVSON8 variants, A7102CGHN1/T0B04EL uses bump-based interconnects and requires microvia PCB routing.
Can the A7102CGHN1/T0B04EL be used for firmware update verification?
Yes, the A7102CGHN1/T0B04EL supports firmware integrity verification through its protected asymmetric key storage and ECDSA signature validation engine. Developers can store up to three trusted public keys and use them to verify signed firmware images before flashing. The monotonic counters further enable replay protection, ensuring A7102CGHN1/T0B04EL only accepts incrementally newer updates - a critical requirement for secure OTA in medical and industrial devices.
