Evaluates: MAX32520 MAX32520 Evaluation Kit General Description Features The MAX32520 evaluation kit (EV kit) provides a platform Arm Cortex M4 Processor with FPU with for evaluation capabilities of the MAX32520 for secure ChipDNA PUF Technology element IoT utilizing Maxims proprietary PUF (physically USB 2.0 Micro B to Serial UART unclonable function) technology. Serial UART Access Selectable Through a USB 2.0 The MAX32520 integrates an Arm Cortex M4 proces- Serial Bridge or from an Optional Host Processor sor with FPU, 2MB of flash, 136KB of system RAM and Security Self-Destruct Jumper 34KB ECC, 8KB of one-time-programmable (OTP) mem- ory and 128KB of boot ROM. It provides a FIPS/ compli- Arm or SWD JTAG 20-Pin Header and Cortex 10-Pin Header ant TRNG, as well as environmental and tamper detection circuitry to facilitate system-level security. Multiple high 40-Pin Connector for Interfacing to a Host Processor speed interfaces are supported including SPI, UART, and 16-Pin Ribbon Cable Connector for Interfacing to QSPI 2 an I C. One of the SPI ports has a serial flash emulation 2 Three PMOD Connectors for Interfacing to SPI, I C, mode allowing direct code fetching enabling secure boot or Timer Modules from a host microcontroller.

Follow the steps (J1). The board is default jumpered for power provided below to verify board operation: by CN1. 1) While observing safe ESD practices, carefully Current Monitoring remove the MAX32520 EV kit board out of its pack- Two pin headers provide convenient current monitoring aging. Inspect the board to ensure that no damage points for VDD (JP11) and VDDA (JP12). occurred during shipment. Jumpers/shunts are preinstalled prior to testing and packaging. UART Interface 2) The MAX32520 is preprogrammed with a demo The EV kit provides a USB-to-UART bridge chip, FTDI program. To run the demo, power up the board by FT230X. This bridge eliminates the requirement for a plugging in the provided USB cable to connector physical RS-232 COM port. Instead, the ICs UART CN1.
