MAX32550-LNS+W

ABRIDGED DATA SHEET EVALUATION KIT AVAILABLE MAX32550 DeepCover Secure Cortex-M3 Flash Microcontroller General Description Benefits and Features The DeepCover Secure microcontroller (MAX32550) provides an interoperable, secure, and cost-effective solution to build new generations of trusted devices such as mobile chip and pin pads. The MAX32550 is based on a Cortex M3 processor with 1MB of embedded flash, 256KB of system RAM, 8KB of battery-backed AES self-encrypted NVSRAM. It includes all the essential functions of mobile POS terminal including a cryptographic engine, a true random number generator, battery-backed RTC, environmental and tamper detection circuitry, a magnetic stripe reader, a smart card controller with embedded transceiver to directly support 1.8V, 3.3V, and 5V cards, and an integrated secure keypad controller. It also provides a seamless interface to TFT displays and includes a vast array of peripherals, SPIs, UARTs, DMA, ADC, and DAC that add flexibility to control and differentiate the system design. ● Security Features Facilitate System-Level Protection • Secure Boot Loader with Public Key Authentication • AES, DES and SHA Hardware Accelerators • Modulo Arithmetic Hardware Accelerator (MAA) Supporting RSA, DSA, and ECDSA • 8-Line Secure Keypad Controller • Hardware True Random-Number Generator • Die Shield with Dynamic Fault Detection • 6 External Tamper Sensors with Independent Random Dynamic Patterns • 256-Bit Flip-Flop-Based Battery-Backup AES Key Storage • Temperature and Voltage Tamper Monitor • Real-Time Clock DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.
