4.34x4.34mm MCU combines cryptography, secure key storage and tamper detection

August 02, 2018 // By Julien Happich
Offered in a 4.34x4.34mm wafer-level package, Maxim’s MAX32558 DeepCover IC secure microcontroller is claimed to be 50% smaller than the nearest competitor.

The MAX32558 DeepCover Arm Cortex-M3 flash-based secure microcontroller delivers strong security in a small footprint while simplifying design integration and speeding time to market. It integrates several security features into a small package, including secure key storage, a secure bootloader, active tamper detection and secure cryptographic engines. It also supports multiple communications channels such as USB, serial peripheral interface (SPI), universal asynchronous receiver-transmitter (UART) and I2C, making it suitable for a wide range of applications. Compliant with Federal Information Processing Standard (FIPS) 140-2 L3&4 certification, the chip reduces footprint by embedding a number of security features specifically to address point-of-sale Payment Card Industry (PCI) pin transaction security (PTS) requirements, as well as several analog interfaces. It comes with 512KB of internal flash and 96KB of internal SRAM. Complete software framework including real-time operating system (RTOS) integration and code examples in evaluation kit.
