MAX32570

Low-Power Arm Cortex-M4 Microcontroller

with Contactless Radio for Secure Applications

General Description

Benefits and Features

● High-Efficiency Microcontroller for Secure Battery

Powered Applications

The MAX32570 DeepCover secure microcontroller pro-

vides 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 al-

so 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 contact-

less controller and radio front-end, a dual smart card con-

troller, a parallel camera inteface, a magnetic stripe read-

er, a TFT controller, and a secure keypad controller.

• Arm Cortex-M4 Processor with FPU up to 150MHz

• 150MHz and 75MHz Internal Oscillators

• Low-Power 7.37MHz System Clock Option

• 1MB Flash, Organized into Dual Banks 2 x 512KB

• 760KB (608KB ECC) SRAM

• Optional Error Correction Code (ECC-SEC-DED)

for Cache, SRAM, and Internal Flash

• 1KB AES Encrypted NVSRAM, 16KB Internal OTP

● Scalable Cached External Memory Interfaces

• QSPI Flash with AES-GCM and XiP

The MAX32570 operates at 150MHz and is based on an

Arm Cortex -M4 with FPU processor with 1MB flash,

760KB SRAM, 4KB OTP, 1KB of battery-backed AES self-

encrypted nonvolatile SRAM (NVSRAM) and a 256-bit flip-

flop based battery-backed key storage. The flash mem-

ory 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 execu-

tion. 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 secu-

rity protections and detectors to enforce system integrity

including a dynamic sensor controller, environmental sen-

sors, and fault detectors.

• QSPI SRAM with AES-GCM and XiP

• 150Mbps SDHC/eMMC/SDIO/microSD Interface

● Security Features Facilitates System-Level Protection

• ISO 14443A/B, JIS X 6319-4, ISO 15693

Contactless Reader with Internal Transceiver

• Secure Boot Loader with Public Key Authentication

• Hardware AES, DES, ECDSA and SHA-2 engines

• 10-Line Secure Keypad Controller*

• TRNG (SP-800-90A and SP-800-90B)

• 6 External Dynamic Tamper Sensors

• Die Shield with Dynamic Random Signal

• 1x 256-Bit and 2x 128-Bit Flip-Flop-Based AES Key

Storage

• Temperature and Voltage Tamper Monitor

• Fault Detectors

The device features five flexible power modes. Multiple

● Optimal Peripheral Mix Provides Platform Scalability

• 16-Channel DMA

SPI, UART, and I C serial interfaces, as well as a QSPI,

1-Wire master, a USB 2.0 High-Speed device, and an

• One QSPI/SPI Master

optional 10/100 Ethernet MAC, allow for greater connec-

tivity. Some device package variants offer flexible off-chip

memory expansion that supports SD/SDHC, SDIO/eMMC

cards, QSPI flash, and SRAM memories with eXecute In

Place (XIP), encryption, and authentication. The device is

available in a number of package variants, ranging from

BGA-81 to BGA-169, 0.65mm pitch packages.
