Evaluates: MAX32670 MAX32670 Evaluation Kit General Description Features The MAX32670 evaluation kit (EV kit) provides a plat- USB 2.0 Micro B to Serial UART Bridge form for evaluation capabilities of the MAX32670. The UART0 and UART3 Interface is Selectable Through MAX32670 is an ultra-low-power, cost-effective, highly On-Board Jumpers reliable 32-bit microcontroller that enables designs with On-Board MAX32625PICO-Based Debugger complex sensor processing without compromising battery life. It combines a flexible and versatile power manage- Boot Load Enable Circuitry ment unit with the powerful Arm Cortex -M4 core with 2 SPI and I C Signals Accessed Through 0.1in floating point unit (FPU). The MAX32670 also offers Headers legacy designs an easy and cost optimal upgrade path GPIOs and Miscellaneous Signals Accessed Through from 8-bit or 16-bit microcontrollers. 0.1in Headers EV Kit Contents Board Power Provided by USB Port MAX32670 EV kit containing a MAX32670 On-Board SIMO Regulator and LDO for IC and Peripherals One standard A to Micro B USB cable Individual Power Measurement on all IC Rails Through Jumpers Ordering Information Two General-Purpose LED and One General- PART TYPE Purpose Pushbutton Switch MAX32670EVKIT EV Kit Denotes RoHS compliance.

MAX32670 EV kit UART Interface One standard A to Micro B USB cable A USB-to-UART bridge, implemented in the MAX32625, Procedure eliminates the requirement for a physical RS-232 COM The EV kit is fully assembled and tested. Use the follow- port. The bridge can be connected to UART0 or LPUART0 ing steps to verify board operation: of the IC with jumpers JP3 (Rx) and JP4 (Tx). 1) While observing safe ESD practices, carefully Host Interface Headers remove the MAX32670 EV kit board out of its 2 The EV kit can communicate by SPI, I C or UART to the packaging. Inspect the board to ensure that no Host processor through 0.1in spaced headers JH2 (SPI), damage occurred during shipment. Jumpers/shunts 2 JH3 (I C) and connector CN1 (UART). The interface type are preinstalled prior to testing and packaging. is set by ISEL0 jumper JP7 and ISEL1 jumper JP8. 2) Power up the board by plugging in the provided USB cable to connector CN1. Verify that the blue LED (D4) GPIO and Alternate Function Headers illuminates and that the green LED (D2) flashes indi - GPIO and alternate function signals from the MAX32670 cating successful completion of board diagnostics. can be accessed through 0.1in spaced headers JH1 and JH2. Detailed Description of Hardware SPI0 Header (or Software) SPI0 signals from the MAX32670 can be accessed Power Supply through 0.1in spaced header JH3. The EV kit is powered by +5V that is made available through V on the Micro-USB type-B connector CN1. Reset Pushbutton BUS The IC can be reset by pushbutton SW2. Current Monitoring Two pin headers provide convenient current monitoring Boot Loader points for V (JP5) and V (JP6). DD CORE Boot load is activated by boot load enable slide switch SW1. Low-Power Mode Current Measurements When attempting to measure the current consumption for Indicator LEDs any of the low-power modes, remove jumpers JP3 and JP4. General-purpose indicators LED D1 (red) is connected to GPIO P0.22 and LED D2 (green) is connected to GPIO Clocking P0.23 The MAX32670 clocking is provided by an external 32MHz crystal (Y1) and an external 32.768kHz crystal GPIO Pushbutton Switch (Y2) for RTC operations. General-purpose pushbutton SW3 is connected to GPIO21. If the pushbutton is pressed, the attached port pin is pulled low. Maxim Integrated 2 www.maximintegrated.com
