DeepCover Secure ARM Cortex-M3 Flash Microcontroller

Description

Create a design and simulate using EE-Sim^® tools:

DeepCover^® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.

The MAX32558 is based on an Arm^® Cortex^®-M3 processor with 512KB of embedded flash, 96KB of system RAM, 1KB of battery-backed AES self-encrypted NVSRAM. It includes 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 includes a vast array of peripherals, USB SPIs, UARTs, DMA, and ADC that add flexibility to control and differentiate the system design.
