Quick StartRequired Equipment

MAX32655 EV Kit Containing a MAX32655 with a Preprogrammed Demo

One USB Standard-A to Micro-B Cable

ProcedureThe EV kit is fully assembled and tested. Follow the steps below to verify board operation:1) While observing safe ESD practices, carefully remove

the MAX32655 EV kit board out of its packaging. Inspect the board to ensure that no damage occurred during shipment. Jumpers/shunts are preinstalled prior to testing and packaging.

2) Power up the board by plugging in the provided USB cable to connector CN1. Verify that the 5V (DS1) blue LED (DS1) and the 3.3V (DS2) and 1.8V (DS2) green LEDs are illuminated.

3) The MAX32655 is preprogrammed with a demo pro-gram. The demo will now initiate and display the Max-im logo upon successful completion.

Detailed Description of HardwarePower Supply The EV kit is powered by +5V, which is made available through VBUS on the USB Micro-B connector CN1. A blue LED (DS1) illuminates when the board is powered. Green LEDs (DS2) and (DS3) illuminate when the 3V3 and 1V8 LDOs are powered, respectively. The MAX32655 itself can be solely sourced by a coin cell battery or on-board 3.3V through the JP8 header.

Current MonitoringTwo pin headers provide convenient current monitor-ing points for VDDIOH (JP10), VDDIO (JP12), VDDA (JP14), VCOREA (JP16), VCOREB (JP18), and BLE_LDO (JP19).

Low-Power Mode Current Measurements PrecautionWhen attempting to measure the current consumption modes, assure that R36 has been removed since it draws extra current.

Clocking The MAX32655 clocking is provided by an external 32MHz crystal (Y1) and an external 32.768kHz crystal (Y2) for RTC operation.

Bluetooth 5.0 Interface An SMA connector is provided to attach an external Bluetooth 2.4GHz antenna.

Color TFT Display The display provided is a 3.5in, 320 x 240 color TFT with an integrated TFT controller from Crystalfontz®. The resistive touch controller is a separate IC that is con-nected to the SPI bus of the MAX32655.

Audio Stereo Codec Interface The MAX32655 interfaces to the MAX9867 external audio codec IC through its I2C and I2S ports. Line-in and line-out 3.5mm jacks are provided for audio access.

Digital Microphone The MAX9867 codec interfaces to a miniature digital microphone embedded on an IC.

MemoryA 128Mb QSPI flash is provided as optional external memory.

JTAG Serial Wire Debug (SWD) Support SWD debug can be accessed through the Cortex 10-pin connector, JH3. Logic levels are fixed to VDDIO (1.8V).

RISC-V JTAG Test PortRISC-V debug can be accessed through a Cortex 10-pin connector, JH4. Logic levels are fixed to VDDIO (1.8V).

UART InterfaceThe EV kit provides a USB-to-UART bridge chip, FTDI FT230X. This bridge eliminates the requirement for a physical RS-232 COM port. Instead, the IC’s UART access is through the USB Micro-B connector, CN1. The USB-to-UART bridge can be connected to the IC’s UART 0 or LPUART with jumpers JP4 (Rx) and JP5 (Tx). Virtual COM port drivers and guides for installing Windows® driv-ers are available at the FTDI chip website.

GPIO and Alternate Function HeadersThe GPIO and alternate function signals from the MAX32655 can be accessed through the 0.1in spaced headers JH6, JH7, JH8, JH9, and JH13.

Analog HeadersThe eight analog outputs can be accessed through the 0.1in spaced headers JH11 and JH12.

I2C PullupsI2C0 and I2C1 ports can independently pulled up to 1V8 or 3V3 through JP21 (I2C0) and JP22 (I2C1).

Reset PushbuttonThe IC can be reset by pushbutton SW2.

Indicator LEDs General-purpose indicator LED D1 (red) is connected to GPIO P0.24, and LED D2 (green) is connected to GPIO P0.25.

GPIO Pushbutton SwitchesThe two general-purpose pushbuttons (SW3 and SW4) are connected to GPIO P0.18 and P1.19, respectively. If the pushbutton is pressed, the attached port pin is pulled low.
