MAX32620 Evaluation Kit

Getting Started

3) Once power is applied, the demo will run. The demo displays text and graphics on the OLED display.

1) While observing safe ESD practices, carefully remove the EV kit board out of its packaging. Quickly inspect the board to make sure that no damage occurred during shipment. Jumpers/shunts were preinstalled prior to testing and packaging. By default, they select the USB interface as the source of power for the EV kit board. See Table 1 and Figure 4 for the default jumper settings and descriptions.

4) If the OLED display does not show a graphics screen, then verify that the USB port is supplying +5V. 5) Do not connect any of the additional USB cables or Olimex JTAG adapter until after the tool chain/drivers are installed. If the demo ran as expected, then the next step is to download and run the installer as described in the Quick Start (separate document). The installer is a small application that allows users to select which components they would like to download and install including tools, drivers, and documentation. A description of each component and the hard drive size required for each can be seen by clicking on each component.

2) The MAX32620/21 was preprogrammed with a demo program. To power up the board and run the demo, simply connect the Micro-USB cable to the MicroUSB jack found at the top left of the EV kit PCB. The jack is labeled CN2. The other end of the Micro-USB cable can be connected either to a computer or to a USB wall charger in order to get +5V power. No data is sent over USB in this demo.

MAX32620 Evaluation Kit

Detailed Description of Hardware

This section describes each major function or component on the MAX32620 EV kit. This EV kit is general-purpose in nature and provides many user-selectable options, which are described in the following sections. Each jumper setting is described and its default setting illustrated.

Board Power

The EV kit’s main power-supply input is +5V, made available through Micro-USB type-B connector CN2. This is the default power source.

Current Monitoring

Jumpers JP15, JP16, JP18, and JP19 provide convenient current monitoring points for VDD12 (JP15), VRTC (JP18), VDDB (JP19), and VDDA+VDD18 (JP16).

Pushbuttons

Pushbuttons (normally open) SW1, SW2, and SW3 can be used to generate a logic 0 signal on their corresponding GPIO port pins. Firmware defines the action taken on switch closure. Pushbutton SW4 provides a global POR reset function for the MAX32620/21 by asserting the RSTN input. Pushbutton SW5 controls the PFN1 input of the PMIC. The function of the PFN1 input is configurable. Refer to the MAX14690 IC data sheet for complete information.

USB

The MAX32620/21 provides an integrated USB2.0 fullspeed interface (12Mbps). This interface is accessed through the Micro-USB type-B connector, CN2. This interface is also the default power source for the EV kit.

USB-UART Bridge

The EV kit board provides a USB-to-UART bridge chip, FTDI FT230X. This bridge eliminates the requirement for a physical RS-232 COM port. Instead, MAX32620/21 UART access is through the Micro-USB type-B connector, CN1. Virtual COM port drivers and guides for installing Windows® drivers are available at www.ftdichip.com. Default parameters are 115,200 baud, 8 bits, no parity, 1 stop bit, no flow control. The USB-to-UART bridge can be connected to UART 0 or UART 1 of the MAX32620/21 with jumpers JP10 (RX), JP12 (TX), JP13 (CTS), and JP14 (RTS).

LEDs

The EV kit board has four LEDs with series currentlimiting resistors. LEDs DS1 (red), DS2 (green), DS3

Evaluates: MAX32620, MAX32621

(red), and DS4 (green) are connected to MAX32620/21 GPIO pins P3.0, P3.1, P3.2, and P3.3, respectively. LED GPIOs should be configured as open drain due to 3.3V LED source voltages. An LED is illuminated when the appropriate GPIO pin is driven low.

Bluetooth Low-Energy (BLE) Controller

The EV kit board has a low-power Bluetooth controller, EM9301. Communication with the MAX32620/21 is through SPI 2B. This particular SPI port was selected due to the additional flow control signals that it features. The EM9301 controller is Bluetooth specification V4.0 compliant. Refer to the EM Microelectronic EM9301 data sheet for additional details.

Clocking

The MAX32620/21 operate from an internal 96MHz relaxation oscillator. The internal oscillator is adequate to run the core digital logic and peripherals. The accuracy of the internal oscillator is not suitable for accurate RTC timekeeping or USB operation. The external 32.768kHz crystal, Y1, provides the RTC with an accurate time base and is also used to calibrate the internal oscillator for the accuracy required for USB operation.

JTAG Connector

The ARM standard 20-pin connector pinout is provided by shrouded header J1. Various debugger modules are available for this interface. The Olimex ARM-USB-TINY-H debugger is supplied with the EV kit.

Graphic OLED Display Module

A 128 x 32 pixel graphic OLED display module, NHD2.23-12832UCB3, is provided on the EV kit board. Communications with the NHD-2.23-12832UCB3 is through SPI 2A.

Power Management IC (PMIC)

The MAX14690 manages the EV kit power rails. It also manages the selection of EV kit power from either VBUS from CN2 or an (optional) external lithium-ion polymer battery. The MAX14690 can also function as a battery charger. Refer to the MAX14690 IC data sheet for additional information.

Prototyping Area

An area for adding customer-specific circuitry is provided. This matrix is on a 0.1in spacing and is usable for solder or wire-wrap construction. Power and ground rails run through the matrix. Windows is a registered trademark and service mark of Microsoft Corp.
