Single-chip secure microcontroller targets multimedia-enabled portable POS terminals
As a single-chip secure microcontroller, the chip integrates an ARM926 core capable of video playback; dual external memory controllers, and extended connectivity options including a 10/100 Ethernet MAC and a USB host and device controller. The chip features 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. The high level of integration shrinks design size and significantly lowers implementation costs. The company also delivers a PCI-PTS 3.1 preapproved, fully functioning financial-terminal reference design.
