Make Mobile Payment Terminals Secure With New MCU


Designers of mPOS terminals, ATM keyboards, EMV card readers, contact/contactless pin pads, and other mobile payment devices can now save PCB space, reduce the BOM, and speed development with the new MAX32560 DeepCover secure microcontroller from Maxim Integrated Products.

MAX32560 integrates security features and payment interfaces to meet latest PCI-PTS standards and reduce development time

The new MAX32560 DeepCover secure ARM Cortex-M3 microcontroller integrates multiple functions into one small chip, eliminating the need for multiple external ICs for memory expansion, contactless interface and amplifier, ISO7816 PHY, magnetic stripe interface, and battery switch functions.

The MCU comes with various security features for addressing stringent PCI-PTS requirements, including active tamper protection, scrambling keypad for PIN handling, and a secure cryptographic engine.


A number of analog interfaces to reduce the PCB footprint are also included, such as a full EMV contactless reader interface, two EMV smart card interfaces, a DSP-based high performance magnetic stripe reader, 2-channel ADC, and a DAC.

Other features include 1MB of embedded flash memory, 384KB of SRAM, and 8KB of secure NVSRAM. The memory can be further expanded through external fast serial flash memories via a flexible QuadSPI controller with XiP, and can quickly read and decrypt code or data using an on-the-fly AES engine.

For communication interfaces, the MAX32560 provides a USB device port, three SPI controllers, two UARTs, and two I²C controllers. In addition, the MCU features a number of power saving modes to minimize power consumption and optimize battery life.

“Because the MAX32560 comes with a pre-certified EMV-L1 contact and contactless software stack, it can be quickly deployed to new designs. To empower our customers with a turnkey solution, Maxim teamed with Alcineo to provide EMV-L2 stack support”, said Gregory Guez, Director, Embedded Security, Maxim Integrated.

The MCU is available in a 9mm x 9mm BGA144 package and operates across the -40-degree Celsius to +85-degree Celsius temperature range.

An evaluation kit, the MAX32560-KIT#, with pricing starting at $1,500, is available now. The pricing for the MAX32560 starts at $9.41 (1,000-up, FOB USA)

Maxim plans to showcase the MAX32560 and other embedded security products at TRUSTECH, November 29 – December 1, in Maxim’s stand, Palais 01 D 043.
