Product details
Overview
A7101CLTK2/T0BC27J 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 (4×), and secure channel SCP03-designed for root-of-trust credential storage and device authentication in industrial gateways and IP cameras.
For engineers reviewing the A7101CLTK2/T0BC27J datasheet, A7101CLTK2/T0BC27J pinout, A7101CLTK2/T0BC27J application, or A7101CLTK2/T0BC27J equivalent, this page delivers verified package mapping (HVSON8), confirmed I²C address options (0x90/0x92), sleep current (40–150 µA), EEPROM endurance (500k cycles), and functional alternatives with documented cryptographic scope differences.
Technical Context
The A7101CLTK2/T0BC27J integrates a dedicated MX51 security CPU and Java Card OS to isolate cryptographic operations from host systems; all memory access is mediated by fixed applet functions, preventing direct host read/write to protected keys or monotonic counters. Its Smartcard I²C (SCI²C) protocol layer maps ISO/IEC 7816-4 APDUs over SMBus-based I²C physical signaling.
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-delivering 10 µA max current at 90 °C. Security countermeasures include hardware-level SPA/DPA protection licensed from Cryptography Research Inc.

Applications
| Industrial Edge Gateway Security | IP Camera Device Authentication |
|---|---|
Use Scenario: Securing firmware updates and TLS handshakes in industrial gateways connecting legacy PLCs to cloud platforms. IC Role / Device Role / Timing Role: Root-of-trust anchor performing ECDSA signature verification of signed firmware images and establishing TLS 1.2/1.3 sessions via ECDH key exchange. Use Value: Prevents unauthorized firmware execution and man-in-the-middle attacks by binding device identity to cryptographically attested credentials stored in tamper-resistant EEPROM. |
Use Scenario: Enabling mutual authentication between IP cameras and video management servers in smart city deployments. IC Role / Device Role / Timing Role: Secure element hosting private keys for device identity assertion during certificate enrollment and session key derivation via ECDH-E. Use Value: Eliminates shared-secret provisioning risks; ensures each camera presents verifiable, non-repudiable identity without exposing private material to host MCU or network stack. |
| Home Appliance Anti-Counterfeiting | Sensor Network Credential Injection |
Use Scenario: Verifying authenticity of replacement parts (e.g., washing machine drum assemblies) using embedded NFC tags linked to A7101CLTK2/T0BC27J-secured cloud records. IC Role / Device Role / Timing Role: Stores immutable proof-of-origin certificates and validates digital signatures on part identifiers during pairing. Use Value: Blocks counterfeit components by enforcing cryptographic proof that hardware matches OEM-issued credentials-no software-only validation possible. |
Use Scenario: Provisioning unique device identities into battery-powered environmental sensors during automated manufacturing test. IC Role / Device Role / Timing Role: Receives and securely stores asymmetric key pairs and public keys via plain injection mode before transport lock activation. Use Value: Enables high-throughput, offline credential injection with guaranteed isolation-keys never reside in host RAM or flash, reducing factory floor attack surface. |
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 | Supports SHA-256, ECC P-256, and AES-128; lacks SCP03, uses custom command set instead of Java Card OS | Targeted at cost-sensitive consumer IoT; no built-in transport lock or monotonic counters | Select when needing lower BOM cost and simpler host driver integration without Java Card ecosystem dependencies |
| SLB9670 | TPM 2.0-compliant discrete Trusted Platform Module; supports RSA-2048, ECC P-256, SHA-256, and PCR registers | Designed for PC/server boot integrity; requires SPI interface and larger PCB footprint (QFN48) | Select when platform-level attestation (e.g., measured boot, remote attestation) is required beyond device-level authentication |
Compared with ATECC608A-TFLXT and SLB9670, the A7101CLTK2/T0BC27J uniquely combines Java Card OS compatibility, SCP03 secure channel, transport lock, and monotonic counters in an HVSON8 package-making it optimal for cloud-connected embedded devices requiring standardized, field-upgradable secure provisioning.

FAQ
What is the operating temperature range of the A7101CLTK2/T0BC27J?
The A7101CLTK2/T0BC27J is an A7101-series device rated for −25 °C to +85 °C ambient operation, as defined in the A71CH type table and confirmed in Section 13 of the datasheet. This distinguishes it from the A7102 variant (−40 °C to +90 °C) and is validated across all electrical and timing characteristics tables.
Does the A7101CLTK2/T0BC27J support both 1.8 V and 3.3 V supply modes?
Yes, the A7101CLTK2/T0BC27J supports dual-voltage operation: 1.62–1.98 V (1V8 mode) and 2.5–3.6 V (3V3 mode), with corresponding current consumption specified in Tables 15 and 16. Voltage mode is auto-detected at power-on; no configuration register setting is required.
What I²C addresses does the A7101CLTK2/T0BC27J use?
The A7101CLTK2/T0BC27J uses two configurable 7-bit I²C addresses: 0x48 (read = 0x49) and 0x49 (read = 0x4A), corresponding to 8-bit addresses 0x90/0x91 and 0x92/0x93 respectively. Selection depends on IF0 and IF1 pin states at power-on, per Table 8.
Is the A7101CLTK2/T0BC27J pin-compatible with other A71CH variants in HVSON8 package?
Yes, all A71CH variants in HVSON8 (e.g., A7101CHTK2/T0BC2VJ, A7102CHTK2/T0BC2AJ) share identical pinout, package dimensions (SOT909-1), and mechanical footprint-enabling drop-in replacement within the same temperature grade and configuration.
What security certifications apply to the A7101CLTK2/T0BC27J?
The A7101CLTK2/T0BC27J inherits the Common Criteria EAL5+ certification of the A71CH platform, validated against AVA_VAN.1, ASE_TSP.1, and ASE_INT.1. It also implements CRI-licensed SPA/DPA countermeasures, though formal certification reports are issued per customer-programmed configuration-not per individual orderable part number.
