Product details
Overview
A7102CGHN1/T0B0AEL 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/verification, ECDH key agreement, and 8×128-bit symmetric secret storage. It operates over I²C Fast-Mode (400 kbit/s), features −40 °C to +90 °C industrial temperature range, and delivers <10 μA deep sleep current for battery-constrained edge nodes.
For engineers reviewing the A7102CGHN1/T0B0AEL datasheet, A7102CGHN1/T0B0AEL pinout, A7102CGHN1/T0B0AEL application, or A7102CGHN1/T0B0AEL equivalent, this page provides verified functional identity, validated HVSON8 pin mapping, confirmed cryptographic capabilities (ECDSA/ECDH/HKDF/HMAC-SHA256), real-world use cases in cloud-connected industrial devices and IP cameras, and two technically documented alternative secure elements with explicit differences in temperature grade and package.
Technical Context
The A7102CGHN1/T0B0AEL implements a dedicated MX51 security CPU with on-chip Java Card OS and fixed IoT applet, enforcing strict memory isolation: host access is restricted to APDU-level commands via Smartcard I²C (SCI²C) protocol-no direct memory access permitted. All cryptographic operations (ECC, AES, HMAC) execute within protected hardware accelerators.
It supports dual-voltage operation (1.62–1.98 V or 2.5–3.6 V), automatic SLEEP mode entry after 312 ms I²C inactivity, and DEEP SLEEP activation via RST_N low pulse ≥500 μs. I²C addressing defaults to 0x90/0x92 (8-bit), configurable by IF0/IF1 pins at power-on.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure element applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| A7101CGHN1/T0BC2VJ | Same HVSON8 package and core functionality, but rated for −25 °C to +85 °C only; lacks extended industrial temperature qualification | Not suitable for outdoor or high-temperature industrial enclosures where A7102CGHN1/T0B0AEL's −40 °C to +90 °C range is required | Select when operating environment remains within commercial temperature range and cost optimization is prioritized |
| A7102CGUK/T0BC2VAZ | Identical temperature grade and cryptographic features, but uses WLCSP12 package (0.5 mm ball pitch) instead of HVSON8 | Requires different PCB layout, reflow profile, and test fixture; smaller footprint but higher assembly complexity than HVSON8 | Select when board space is constrained and advanced packaging capability exists |
Compared with A7101CGHN1/T0BC2VJ and A7102CGUK/T0BC2VAZ, the A7102CGHN1/T0B0AEL uniquely combines extended industrial temperature operation with the robust, reflow-friendly HVSON8 package-making it optimal for ruggedized edge deployments where thermal reliability and manufacturability are co-prioritized.

FAQ
What is the exact package type and footprint of A7102CGHN1/T0B0AEL?
A7102CGHN1/T0B0AEL uses the HVSON8 package (SOT909-1) with 4 mm × 4 mm × 0.85 mm body dimensions and an exposed thermal pad. The pinout matches the standard HVSON8 configuration: I2C_SCL (pin 1), VSS (pin 2), IF0 (pin 3), n.c. (pin 4), IF1 (pin 5), RST_N (pin 6), VCC (pin 7), and I2C_SDA (pin 8). The thermal pad is not electrically connected but should be soldered to a ground plane for thermal performance.
Does A7102CGHN1/T0B0AEL support both 1.8 V and 3.3 V operation?
Yes, A7102CGHN1/T0B0AEL supports dual-voltage operation: 1.62–1.98 V (1V8 mode) and 2.5–3.6 V (3V3 mode). In 1V8 mode, typical active current is 2.45 mA (no coprocessor) and 7.5 mA (ECC active); in 3V3 mode, it draws 7.0 mA (no coprocessor) and 15.1 mA (ECC active). Voltage mode is auto-detected at power-on based on VDD level.
How does A7102CGHN1/T0B0AEL handle secure boot and transport locking?
A7102CGHN1/T0B0AEL supports transport lock via its IoT applet: the module can be placed in a locked state preventing further credential writes until explicitly unlocked by authorized host commands. This enforces one-time secure provisioning during manufacturing. Transport lock is independent of debug mode status and persists across power cycles.
What cryptographic algorithms and key lengths does A7102CGHN1/T0B0AEL natively accelerate?
A7102CGHN1/T0B0AEL natively accelerates ECDSA and ECDH using only NIST P-256 elliptic curve (256-bit keys), HMAC-SHA256, AES-128 (for SCP03 secure channel), and HKDF key derivation. It stores 4×P-256 key pairs, 3×public keys, 8×128-bit symmetric secrets, and supports monotonic counters-but does not support RSA, Ed25519, or curves beyond P-256.
Can A7102CGHN1/T0B0AEL be used with Linux-based hosts like i.MX 6UL?
Yes, A7102CGHN1/T0B0AEL is fully supported on Linux hosts including i.MX 6UL via NXP's open-source host library and OpenSSL/Mbed TLS ENGINE integration. The library handles SCI²C protocol framing, APDU marshaling, and secure channel setup-enabling direct use of standard crypto APIs without low-level I²C driver development.
