Description

The DeepCover® secure microcontroller (MAX32570) provides an interoperable, secure, and cost-effective solution to build new generations of trusted devices. It can be used in single-chip applications such as pinpads, mobile POS (MPOS), and secure card reader for PIN (SCRP), but also in dual-chip applications such as countertop and tablet POS. It includes all the essential functions to address those applications including a multi-protocol RF contactless controller and radio front-end, a dual smart card controller, a parallel camera inteface, a magnetic stripe reader, a TFT controller and a secure keypad controller.

The MAX32570 operates at 150MHz and is based on an Arm® Cortex®-M4 processor with FPU with 1MB flash, 760KB SRAM, 4KB OTP, 1KB of battery-backed AES self-encrypted NVSRAM and a 256-bit flip-flop based battery-backed key storage. The flash memory is split into 2 banks of 512KB to provide flexibility when programming over-the-air. Error correction coding (ECC) (single error correction double error detection) for flash, and SRAM provides extremely reliable code execution. The device embeds both secure public and private key cryptographic algorithms and a true random number generator (TRNG) compliant with SP-800-90A and SP-800-90B standards. It also features a number of security protections and detectors to enforce system integrity including a dynamic sensor controller, environmental sensors, and fault detectors.

The device features five flexible power modes. Multiple SPI, UART, and I²C serial interfaces, as well as a QSPI, 1-Wire® master, and USB 2.0 High-Speed device and anoptional 10/100 Ethernet MAC, allow for greater connectivity. The device offers, on some package variants, flexible off-chip memory expansion that supports SD/SDHC,SDIO/eMMC cards, QSPI flash, and SRAM memories witheXecute In Place (XIP), encryption, and authentication.The device is available in a number of package variantsranging from BGA-81 to BGA-169, 0.65mm pitch package.
