Product details
Overview
A7004CGHN1/T1AGBEL from NXP Semiconductors is a tamper-resistant secure authentication microcontroller featuring the dedicated MX51 security CPU, 76.4 kB EEPROM, I²C slave interface (100 kbit/s), ISO/IEC 7816 contact interface, and JCOP 2.4.2 R1 operating system. It delivers cryptographic acceleration for RSA-2048, ECC-320, AES-128/192/256, and triple-DES, with active shielding, asynchronous handshake technology, and 40 µA sleep current - deployed in embedded secure element applications for industrial M2M authentication.
For engineers reviewing the A7004CGHN1/T1AGBEL datasheet, A7004CGHN1/T1AGBEL pinout, A7004CGHN1/T1AGBEL application, or A7004CGHN1/T1AGBEL equivalent, key selection criteria include extended temperature operation (−40 °C to +90 °C), die-specific X.509 certificate pre-installation, hardware TRNG (AIS-31 compliant), on-chip PKI coprocessor, and JCOP 2.4.2 R1 compliance with Java Card v3.0.1 Classic and GlobalPlatform 2.1.1.
Technical Context
The A7004CGHN1/T1AGBEL implements an asynchronous self-timed handshake architecture to resist timing-based side-channel attacks and integrates NXP's Secure Fetch Technology to protect ROM/RAM/EEPROM code fetches against laser fault injection. Its MX51 CPU extends the 80C51 core with linear addressing, Java/C optimization, and low-power high-speed execution at up to 62 MHz.
Hardware security includes active shielding, enhanced sensors (voltage, temperature, light, SFI detection), and >100 countermeasures against physical and logical attacks. The device supports dual-interface operation via I²C and ISO/IEC 7816 T=0/T=1 protocols, with no ISO/IEC 14443 support - distinguishing it from A7005/A7006 variants.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure authentication microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| A7003CGHN1/T1AGBEL | Same package and core, but rated for −25 °C to +85 °C; identical EEPROM, crypto, and interfaces | Limited to commercial/indoor environments; lacks extended temperature qualification | Select when ambient conditions remain within −25 °C to +85 °C and cost sensitivity favors lower-temperature grade |
| A7006CGHN1/T1AGBEL | Adds ISO/IEC 14443 A contactless interface and MIFARE compatibility; same temperature range and crypto engines | Supports dual-interface (contact + contactless) use cases like hybrid smart cards or NFC-enabled secure modules | Select when contactless authentication or MIFARE ecosystem integration is required alongside contact interface |
Compared with A7003CGHN1/T1AGBEL, A7004CGHN1/T1AGBEL adds extended temperature operation without sacrificing security features; compared with A7006CGHN1/T1AGBEL, it omits contactless capability to reduce BOM cost and simplify layout where only contact-based authentication is needed.
