MAX32552：DeepCover Secure Cortex-M3 Flash Microcontroller

Secure Cortex-M3 Flash Microcontroller with XiP QuadSPI interface

DeepCover®embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible. The DeepCover Secure microcontroller (MAX32552) provides an interoperable, secure, and cost-effective solution to build new generations of trusted devices such as mobile chip and pin pads. The MAX32552 is based on a Cortex®-M3 processor with 1MB of embedded flash, 384KB of system RAM, 8KB of battery-backed AES self-encrypted NVSRAM. In addition to a high-performance QSPI® interface for secure code execution and data storage, it includes most of 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 monochrome graphic displays and includes a vast array of peripherals, SPIs, UARTs, DMA, ADC, and DAC that add flexibility to control and differentiate the system design.
