Product details
Overview
A7004CIHN1/T1AGBAJ from NXP Semiconductors is a tamper-resistant secure microcontroller (MCU) built on the hardened MX51CPU core, delivering Java Card Open Platform (JCOP) 2.4.2 R1 OS with pre-installed X.509 client authentication. It features 76.4 kB EEPROM, I²C slave interface (100 kbit/s), ISO/IEC 7816 contact interface, and operates from −40 °C to +90 °C - designed for embedded secure element applications in industrial IoT gateways requiring high-assurance device identity and PKI-based TLS handshake offload.
For engineers reviewing the A7004CIHN1/T1AGBAJ datasheet, A7004CIHN1/T1AGBAJ pinout, A7004CIHN1/T1AGBAJ application, or A7004CIHN1/T1AGBAJ equivalent, key selection criteria include its certified secure fetch technology, hardware-accelerated RSA-2048/ECC-320 coprocessor, JCOP V3.0.1 classic compliance, die-specific key provisioning, and support for GlobalPlatform 2.1.1 applet management - all within an HVQFN32 package optimized for space-constrained trusted execution environments.
Technical Context
The A7004CIHN1/T1AGBAJ implements an asynchronous self-timed handshake architecture to resist timing-based side-channel attacks, paired with active shielding and NXP glue logic for physical tamper resistance. Its Secure_MX51 CPU executes Java Card applets under JCOP 2.4.2 R1 while coordinating cryptographic operations across dedicated AES, Triple-DES, and PKI coprocessors.
Hardware security is enforced via integrated sensors (voltage, temperature, light, SFI detection), low-power TRNG (AIS-31 compliant), and on-chip key generation. The I²C slave interface supports wake-up from 40 µA sleep mode, and the ISO/IEC 7816 interface enables interoperability with legacy smart card infrastructure - both confirmed for this exact variant per Table 4 and Section 2.2.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure authentication microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST33HTPH2048A | ARM SecurCore SC000 core; 2048-bit RSA; supports ISO/IEC 14443 but lacks I²C slave interface | Targeted at contactless payment terminals; requires SPI host interface instead of I²C | Select when contactless reader integration is primary requirement and I²C connectivity is not needed |
| Infineon SLB9670 | TPM 2.0-compliant; discrete TPM chip with LPC interface; no Java Card OS or applet support | Designed for PC/server BIOS-level trust anchors; not suitable for embedded applet deployment | Select for x86/ARM server platforms requiring standard TPM 2.0 stack - not for custom Java Card applet development |
Compared with ST33HTPH2048A and Infineon SLB9670, the A7004CIHN1/T1AGBAJ uniquely combines I²C slave + ISO/IEC 7816 dual-interface support, JCOP 2.4.2 R1 with X.509 client auth pre-installed, and −40 °C to +90 °C qualification - making it the only option for industrial embedded systems needing both wired host communication and smart-card interoperability in one die.

FAQ
What is the operating temperature range specified for the A7004CIHN1/T1AGBAJ?
The A7004CIHN1/T1AGBAJ is rated for −40 °C to +90 °C operational ambient temperature, as confirmed in Section 2.2 and Table 4 of the A700x family short data sheet. This extended range qualifies the device for industrial control panels, automotive under-hood telematics modules, and outdoor smart grid infrastructure where thermal cycling exceeds commercial-grade limits. The specification applies to the full A7004 variant regardless of packaging or firmware configuration.
Does the A7004CIHN1/T1AGBAJ support both I²C and ISO/IEC 7816 interfaces simultaneously?
Yes, the A7004CIHN1/T1AGBAJ supports concurrent I²C slave (100 kbit/s) and ISO/IEC 7816 T=0/T=1 contact interfaces, as explicitly stated in Section 2.2 and Table 4. This dual-interface capability enables hybrid system architectures - for example, using I²C for host MCU communication while connecting to legacy smart card readers via the 7816 interface. Both interfaces operate independently with separate power domains (VDD and PVDD/CLK).
What cryptographic algorithms are accelerated in hardware by the A7004CIHN1/T1AGBAJ?
The A7004CIHN1/T1AGBAJ integrates dedicated hardware coprocessors for RSA up to 2048-bit, ECC over GF(p) up to 320-bit, AES-128/192/256, and 2-key/3-key Triple-DES. These accelerators are documented in Sections 1.1, 2.1, and Figure 1, and enable full TLS 1.2 handshake offload without host CPU involvement. SHA-1, SHA-224, SHA-256, MD5, and SEED are also supported in hardware per Section 2.1.
Is JCOP 2.4.2 R1 pre-installed on the A7004CIHN1/T1AGBAJ, and what does it include?
Yes, JCOP 2.4.2 R1 is factory-preloaded on the A7004CIHN1/T1AGBAJ, including X.509 certificate-based client authentication applet, GlobalPlatform 2.1.1 support, and Java Card 3.0.1 Classic API compliance. As stated in Sections 1.1 and 5.1.3, this OS image is delivered with die-specific keys and certificates provisioned in a certified HSM environment - no field personalization is required to begin secure TLS client authentication.
What package type is used for the A7004CIHN1/T1AGBAJ, and are thermal pads exposed?
The A7004CIHN1/T1AGBAJ uses the HVQFN32 package (SOT617-1), measuring 5 × 5 × 0.85 mm with no external leads. Per Table 3, this package includes an exposed thermal pad on the underside of the body - essential for thermal management in high-reliability industrial applications. The pad must be soldered to a PCB thermal plane per IPC-7351B guidelines to maintain junction temperature within safe limits during sustained cryptographic operation.
