Product details
Overview
A7102CGHN1/T0B041J from NXP Semiconductors is a Plug & Trust Secure Element IC implementing Java Card OS and preloaded IoT security applet, supporting I²C Fast-Mode (400 kbit/s), ECC NIST P-256 key pair management, ECDSA signature/verification, ECDH key agreement, and monotonic counter storage - deployed in industrial edge devices requiring tamper-resistant credential injection and cloud-authenticated device onboarding.
For engineers reviewing the A7102CGHN1/T0B041J datasheet, A7102CGHN1/T0B041J pinout, A7102CGHN1/T0B041J application, or A7102CGHN1/T0B041J equivalent, this page delivers verified package mapping (WLCSP12), confirmed operating temperature (−40 °C to +90 °C), validated I²C address options (0x90/0x92), real-world power consumption (10 μA deep sleep), and functional alternatives for secure element selection in constrained IoT nodes.
Technical Context
The A7102CGHN1/T0B041J integrates a dedicated MX51 security CPU with on-chip Java Card OS and fixed IoT applet, enforcing strict memory isolation via protected access control - all cryptographic operations (ECDSA, ECDH, HMAC-SHA256, HKDF) execute within hardened hardware boundaries without host CPU intervention. It implements Smartcard I²C (SCI²C) protocol over SMBus-based I²C physical layer, compliant with ISO/IEC 7816-4 APDU mapping.
Its dual-voltage operation (1.62–1.98 V or 2.5–3.6 V) supports battery-powered and mains-powered deployments; automatic SLEEP mode activation after 312 ms I²C inactivity and DEEP SLEEP entry via RST_N low pulse (>500 μs) enable ultra-low-power credential storage in always-on sensor gateways and IP cameras.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure element applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSAFE-A110 | Supports I²C up to 1 MHz; includes AES-128 coprocessor but no native ECC P-256 acceleration | Preferred for AES-heavy use cases (e.g., encrypted firmware delivery); lacks built-in ECDSA/ECDH for lightweight TLS | Select when AES performance > ECC agility; verify host-side ECDSA stack availability |
| Infineon OPTIGA™ Trust M | Offers same ECC P-256 support and 1.8 V operation; uses different SCI²C variant and lacks transport lock feature | Better suited for automotive ASIL-B designs; requires separate provisioning toolchain vs. NXP's A71CH SDK | Choose for automotive qualification needs; confirm compatibility with existing NXP host libraries |
Compared with STSAFE-A110 and OPTIGA™ Trust M, the A7102CGHN1/T0B041J delivers tighter integration with NXP MCU platforms (i.MX/Kinetis), native SCP03 support out-of-box, and hardware-enforced transport lock - making it optimal for rapid, standards-compliant IoT device onboarding where credential lifecycle control is critical.

FAQ
What is the exact package type and footprint of A7102CGHN1/T0B041J?
A7102CGHN1/T0B041J uses the WLCSP12 package (wafer-level chip-scale package, 12-bump, 0.5 mm ball pitch). Its footprint matches JEDEC MO-220 specifications with balls arranged in a 3×4 grid; balls A1, B1, B3, and C1 are not connected and may serve as routing vias to VCC (B2). The center pad is absent - unlike HVSON8 variants - eliminating thermal pad layout complexity.
Does A7102CGHN1/T0B041J support both 1.8 V and 3.3 V operation?
Yes, A7102CGHN1/T0B041J supports dual-voltage operation: 1.62–1.98 V (1V8 mode) and 2.5–3.6 V (3V3 mode). Voltage mode is auto-detected at power-on. In 1V8 mode, typical active current is 2.45 mA (no coprocessor) and deep sleep remains 10 μA - making A7102CGHN1/T0B041J ideal for coin-cell or energy-harvesting IoT nodes.
How does the I²C address configuration work on A7102CGHN1/T0B041J?
A7102CGHN1/T0B041J offers two configurable I²C addresses: 0x90/0x91 (default) or 0x92/0x93. Address selection depends on IF0 and IF1 pin states at power-on: IF0=0, IF1=1 yields 0x90/0x91; IF0=1, IF1=1 yields 0x92/0x93. Both addresses support standard 7-bit addressing (0x48 or 0x49) and require stable pin levels for ≥500 μs after POR.
What cryptographic algorithms are hardware-accelerated in A7102CGHN1/T0B041J?
A7102CGHN1/T0B041J provides dedicated hardware acceleration for ECDSA signature/verification and ECDH key agreement using NIST P-256 curves only. It also accelerates HMAC-SHA256 (one-shot or sequential), HKDF key derivation, and AES-128 (via SCP03 channel keys). RSA and other ECC curves (e.g., secp384r1) are not supported - all crypto executes within isolated Java Card applet context.
Can A7102CGHN1/T0B041J be used without modifying host MCU firmware?
Yes - A7102CGHN1/T0B041J ships with preloaded IoT applet and supports NXP's host library (for i.MX/Kinetis MCUs) and OpenSSL/Mbed TLS ENGINE integration. Developers can enable secure boot, TLS client auth, or credential provisioning using standard APDU commands without writing low-level crypto code - significantly accelerating design-in for A7102CGHN1/T0B041J in production systems.
