Mobile payment device designers currently have to use multiple external integrated circuits for memory expansion, contactless interfaces and amplifiers, ISO7816 PHY, magnetic stripe interface, and battery switch functions. These additional components increase board size and certification time. With the new MAX32560 DeepCover Secure ARM® Cortex®-M3 microcontroller, these functions have been integrated onto a single chip, eliminating the need for up to six external chips.
The MAX32560 incorporates all the necessary security features to meet stringent PCI-PTS requirements, including active tamper protection, a keypad encoding PIN management system, and a secure cryptographic engine. It integrates a range of analog interfaces to reduce the PCB footprint, including a full EMV contactless reader interface, two EMV smart card interfaces, a high-performance DSP magnetic stripe reader, a 2-channel ADC, and a DAC.
The MAX32560 offers 1 MB of built-in flash memory, 384 KB of SRAM, and 8 KB of secure NVSRAM. The memory can be further expanded via fast external flash memory through a flexible QuadSPI controller with XiP, and it can quickly read and decrypt code or data using an on-demand AES engine. For communication interfaces, the MAX32560 provides one USB device port, three SPI controllers, two UARTs, and two I²C controllers. It is available in a 9 mm x 9 mm BGA144 package and operates across a temperature range of -40°C to +85°C.
