A7001AGHN1/T1AG315

Overview

The NXP A7001AGHN1/T1AG315 is a tamper-resistant secure microcontroller from the A700x family, utilizing a dedicated MX51CPU based on an enhanced 80C51 architecture. It operates within a voltage range of 1.62 V to 5.5 V and features up to 76 kB of EEPROM for application code and data storage. The device includes a high-performance PKI coprocessor supporting RSA up to 2048-bit keys and ECC over GF(p) up to 320-bit keys, alongside secured AES and Triple-DES engines. It runs the JCOP 2.4.2 R1 operating system compliant with Java Card V3.0.1 classic and Global Platform specifications.

Feature Summary

• Dedicated security hardened MX51CPU with asynchronous self-timed handshake technology
• On-chip JCOP 2.4.2 R1 embedded operating system with pre-installed X.509 client authentication applet
• High-performance cryptographic coprocessors: RSA (up to 2048-bit), ECC (up to 320-bit), AES, and Triple-DES
• Secure memory with 76 kB EEPROM, 25-year retention, and 500,000 write cycle endurance

Applications

• Embedded security for mobile phones and portable devices
• Counterfeit protection and anti-cloning for hardware and software
• Conditional access to software, content, and features
• Secure machine-to-machine (M2M) communication and transaction signing

Procurement Notes

Verify that the ordering suffix HN1 corresponds to the HVQFN32 package (SOT617-1) as specified in the datasheet. Confirm the operational temperature range matches the specific variant requirements, as the A7001 typically supports -25 °C to +85 °C. Ensure compliance with any necessary Non-Disclosure Agreements (NDAs) required by NXP Semiconductors for accessing detailed design documentation or samples.

Selection Notes

Select this component when a tamper-resistant MCU with Java Card compatibility is required for secure authentication applications. The A7001 variant is suitable for environments requiring -25 °C to +85 °C operation. Consider the A7002 or A7004 variants if industrial temperature ranges (-40 °C to +90 °C) are needed. Verify interface requirements, as this model primarily utilizes I2C, while other family members offer optional ISO/IEC 7816 or 14443 interfaces.

Part Context

The A7001AGHN1/T1AG315 belongs to the A700x family of secure authentication microcontrollers. This family is designed for high-security applications such as bank cards, electronic passports, and embedded secure elements in mobile devices. The 'A' in the naming convention indicates the presence of generic X.509 based client authentication firmware, while 'G' denotes no additional custom application layer firmware beyond the OS.

Replacement Considerations

Direct replacements within the A700x family include the A7002AGHN1/T1AG315 for extended temperature ranges (-40 °C to +90 °C). For contact interface support, consider the A7003AGHN1/T1AG315. For dual-interface (contact and contactless) capabilities, the A7005AGHN1/T1AG315 or A7006AGHN1/T1AG315 are appropriate alternatives.
