The Deep Cover MAX32590 from Maxim Integrated Products, Inc. is the industry’s most secure and highly integrated microcontroller, according to the company. Targeted for financial terminals and new generations of trusted devices such as multimedia-enabled, portable EFT-POS terminals, the MAX3250 complies with the newest security standards..

The single-chip MAX32590 is a major advance over prior designs that required numerous additional discrete components for financial terminals. External memory encryption and integrity checking both simplify system integration and provide better IP protection and stronger overall protection against attacks. The high level of integration shrinks design size and significantly lowers implementation costs. A full financial-terminal reference design based on the MAX32590 dramatically hastens the design time to market.


Key Advantages
  • High integration reduces cost: an ARM926 core is capable of video playback; dual external memory controllers; extended connectivity options including a 10/100 Ethernet MAC and a USB host and device controller.
  • Shorter time to market: a financial terminal reference design provides a PCI-PTS 3.1 preapproved, fully functioning, plug-and-play financial terminal that runs a secure Linux BSP.
  • Protects the external memories: unique, on-the-fly external memory encryption and integrity checking.
  • High levels of integrated security: 24kB AES user-encryptable NVSRAM and 256-bit flip-flop key storage with instant erase capability upon tampering; dynamic sensor and environmental sensor controllers for intrusion detection; hardware cryptographic engines; and a public key-based secure bootloader.
