Product details
Overview
A7002CMHN1/T1AGBEL from NXP Semiconductors is a tamper-resistant secure microcontroller (MCU) built on the hardened MX51CPU core, delivering Java Card 3.0.1 and GlobalPlatform 2.1.1 compliance, 76.4 kB EEPROM, 3.2 kB transient heap RAM, and cryptographic acceleration for RSA-2048, ECC-320, AES-128/192/256, and triple-DES. It operates from −40 °C to +90 °C and interfaces via 100 kbit/s I²C as a slave device in embedded authentication systems.
For engineers reviewing the A7002CMHN1/T1AGBEL datasheet, A7002CMHN1/T1AGBEL pinout, A7002CMHN1/T1AGBEL application, or A7002CMHN1/T1AGBEL equivalent, key selection criteria include its extended temperature range, JCOP 2.4.2 R1 OS with pre-installed X.509 client authentication, hardware TRNG (AIS-31 compliant), active shielding, and asynchronous handshake technology - all validated for high-assurance identity and transaction signing in constrained environments.
Technical Context
The A7002CMHN1/T1AGBEL implements a dedicated Secure_MX51 CPU using asynchronous self-timed handshake logic to resist timing-based side-channel attacks. Its security architecture integrates NXP's Secure Fetch Technology, active shielding, and >100 countermeasures against DPA/SPA, fault injection, and reverse engineering.
It embeds a full PKI coprocessor supporting RSA up to 2048-bit and ECC over GF(p) up to 320-bit, alongside secured AES and triple-DES coprocessors. The device runs JCOP 2.4.2 R1 firmware with Java Card 3.0.1 Classic API support and includes IO configuration APIs for dynamic I²C address reassignment and GPIO control - features confirmed for the A7002 variant per Section 1.5 and Table 4.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure authentication microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| A7004CMHN1/T1AGBEL | Adds ISO/IEC 7816 contact interface; identical EEPROM, crypto engines, and temperature range | Required where legacy smart card readers or dual-interface (contact + contactless) systems are deployed | Select A7004CMHN1/T1AGBEL only if 7816 support is mandatory; otherwise A7002CMHN1/T1AGBEL reduces BOM cost and layout complexity |
| SLB9670 | TPM 2.0-compliant discrete Trusted Platform Module; SPI interface; no Java Card OS or applet runtime | Targets PC/server BIOS-level attestation, not embedded Java Card applet ecosystems or mobile credentialing | Choose SLB9670 for UEFI Secure Boot integration; A7002CMHN1/T1AGBEL remains optimal for Java-based credential issuance and M2M mutual auth |
Compared with A7004CMHN1/T1AGBEL, the A7002CMHN1/T1AGBEL omits 7816 pins and firmware layers - reducing attack surface and power use for pure I²C-connected edge devices. Versus SLB9670, it delivers full Java Card programmability and pre-certified X.509 client auth, enabling rapid deployment of custom PKI workflows without host-side crypto stack development.

FAQ
What is the operating voltage range supported by the A7002CMHN1/T1AGBEL?
The A7002CMHN1/T1AGBEL supports an operating voltage range of 1.62 V to 5.5 V, enabling direct integration with diverse host systems including 1.8 V, 3.3 V, and 5 V microcontrollers without level-shifting circuitry. This wide range is specified in Table 2 of the A700X_FAM_SDS and validated across the full −40 °C to +90 °C temperature envelope. The A7002CMHN1/T1AGBEL maintains functional integrity and cryptographic performance across this entire voltage span.
Does the A7002CMHN1/T1AGBEL include pre-installed firmware, and what does it provide?
Yes, the A7002CMHN1/T1AGBEL ships with JCOP 2.4.2 R1 firmware pre-installed, including a certified X.509 certificate-based client authentication application. This enables immediate TLS/DTLS client authentication without host-side crypto implementation. The OS supports Java Card 3.0.1 Classic APIs and GlobalPlatform 2.1.1 secure domain management. The A7002CMHN1/T1AGBEL also includes die-specific keys and certificates provisioned in a Common Criteria–certified NXP environment.
What cryptographic algorithms are accelerated in hardware by the A7002CMHN1/T1AGBEL?
The A7002CMHN1/T1AGBEL 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. It also includes SHA-1, SHA-224, SHA-256, MD5, SEED, and a hardware TRNG compliant with AIS-31. These accelerators are confirmed in Sections 1.1, 2.1, and Table 4 of the A700X_FAM_SDS and reduce host CPU load for PKI operations in the A7002CMHN1/T1AGBEL.
Is the A7002CMHN1/T1AGBEL pin-compatible with other members of the A700x family?
No - the A7002CMHN1/T1AGBEL uses the HVQFN32 (SOT617-1) package and shares pinout with A7001/A7003/A7004/A7005/A7006 variants in the same package option, but differs functionally from A7003–A7006 which integrate ISO/IEC 7816 or 14443 interfaces. Pin compatibility is limited to I²C-only variants (A7001/A7002) in HVQFN32; A7002CMHN1/T1AGBEL lacks 7816/14443 signal pins present in higher-variant packages.
How does the A7002CMHN1/T1AGBEL achieve resistance to side-channel attacks?
The A7002CMHN1/T1AGBEL employs multiple hardware-level countermeasures: asynchronous self-timed handshake logic eliminates clock-driven power/timing leakage; Secure Fetch Technology protects code fetches from laser fault injection; active shielding detects physical probing; and the triple-DES coprocessor is hardened against first-order DPA. These measures - documented in Sections 1.6 and 2.1 - collectively exceed EMVCo and Common Criteria EAL5+ requirements for the A7002CMHN1/T1AGBEL.
