Product Details

The MAX32520 evaluation kit (EV kit) provides a platform for evaluation capabilities of the MAX32520 for secure element IoT utilizing Maxim’s proprietary PUF (physically unclonable function) technology.

The MAX32520 integrates an Arm® Cortex® M4 processor with FPU, 2MB of flash, 136KB of system RAM and 34KB ECC, 8KB of one-time-programmable (OTP) memory and 128KB of boot ROM. It provides a FIPS/ compliant TRNG, as well as environmental and tamper detection circuitry to facilitate system-level security. Multiple high speed interfaces are supported including SPI, UART, and an I2C. One of the SPI ports has a serial flash emulation mode allowing direct code fetching enabling secure boot from a host microcontroller.
