General DescriptionThe MAX78000 evaluation kit (EV kit) provides a platform for leveraging the capabilities of the MAX78000 to build new generations of artificial intelligence (AI) devices.The EV kit features a socketed MAX78000. Onboard hardware includes a digital microphone, a gyroscope/accelerometer, parallel camera module support and a 3.5in touch-enabled color TFT display. A secondary dis-play is driven by a power accumulator for tracking device power consumption over time. Uncommitted GPIO as well as analog inputs are readily accessible through 0.1in pin headers. Primary system power as well as UART access is provided by a USB Micro-B connector. A USB to SPI bridge provides rapid access to onboard memory, allow-ing large networks or images to load quickly.

Quick StartRequired Equipment
● MAX78000 EV Kit ● One USB Standard-A to USB Micro-B Cable
ProcedureThe MAX78000 EV kit comes preloaded with a MAX78000 device that has been preprogrammed with a sample application. This application blinks an LED and repeatedly outputs messages to its UART. Use this application to verify the hardware is connected and functioning properly. Follow the steps below to verify board operation:1) While observing safe ESD practices, carefully re-
move the MAX78000 EV kit board out of its packag-ing. Inspect the board to ensure that no damage occurred during shipment. Jumpers/shunts are preinstalled prior to testing and packaging.
2) Begin by making sure the PWR switch (SW1) is in the “OFF” position.
3) Make sure that jumper JP1 is installed. This jumper enables LED, D1. Also, make sure that the P0_0 and P0_1 jumpers are installed on JH1. These two jumpers connect UART0 RX and TX to the console output.
4) Connect a USB cable from the PC to the USB/PWR connector (CN1) of the EV kit. This cable will power the board and provide a virtual serial port connection to the MAX78000 UART.
5) On your PC, open a serial terminal application (such as minicom or gtkterm), and connect to the virtual serial port using a baud rate of 115200bps and 8-N-1 settings.
6) Move the PWR switch to the “ON” position.7) You will see message from the MAX78000 appear in
the terminal, and LED1 (D1) on the board will begin blinking at a steady rate. This verifies proper EV kit operation.
Detailed Description of Hardware (or Software)Power SupplyThe EV kit is powered by +5V sourced from VBUS on the USB Micro-B connector CN1. The IC features an integrat-ed SIMO switching power supply, offering high efficiency and supporting low-power-drain operating modes. The CNN power boost circuit supplements the single-input multiple-output (SIMO), supporting the CNN core when peak computing speed is required.
Current MonitoringTwo-pin jumper JP21 provides a convenient current moni-toring point for total MAX78000 consumption. All device current passes through this jumper. In addition, jumpers JP8 through JP12 provide both current monitoring points on individual device power rails, plus a way to bypass the internal SIMO regulator with onboard LDO regulators.
Power AccumulatorThis specialized IC, U13, provides cumulative power con-sumption data on major internal blocks of the MAX78000. Raw data is formatted for display by the power data processor, U20, which drives an onboard OLED display. Operating mode options are selected with the LEFT and RIGHT power mode pushbuttons, which cycle through the available options using the OLED display.
UART – USB BridgeThe EV kit includes an FTDI FT230X USB-to-UART bridge chip. This eliminates the requirement for a physical RS-232 COM port. Instead, the MAX78000 UARTs are accessed through a USB Micro-B connector, CN1. UART 0 and UART 1 are selected using JH1 and JH2, which also provide direct access to the MAX78000 UARTs, bypassing the bridge chip. Virtual COM port drivers and guides for installing Windows® drivers are available at the FTDI chip website.
QSPI – USB BridgeThe EV kit includes an FTDI FT4222 QSPI-to-UART bridge chip. This provides rapid access to system memory for loading network and image data.

I2SAn onboard digital microphone is provided along with a low-jitter 12.288MHz clock oscillator and provisions for external I2S clocking using SMA connector J5.
Color TFT Display with Touch ControlThe display provided is a 3.5in, 320 x 240 color TFT. It has three-wire serial control and a white LED backlight, and it uses a resistive touch-sensitive screen.
RV JTAG/ Arm® SWD (Serial Wire Debug) SupportRISC V coprocessor JTAG is accessed through an Arm Cortex® standard 10-pin connector (JH4). Logic levels are set to VDDIO (1.8V). A hardware (HW) reset may be enabled using JP18, but this function is normally reserved for the Arm Cortex processor using SWD through an Arm Cortex standard 10-pin connector (JH5), also using VDDIO (1.8V) levels.
Reset PushbuttonPushbutton SW5 manually resets the MAX78000.
Auxiliary LEDsThe indicator LED1 (D1) is connected to GPIO P0.2. Indicator LED2 (D2) is connected to GPIO P0.3. These GPIOs must be configured for VDDIOH (3.3V) for proper operation. Buffer U2 prevents loading the ports, since these ports also may serve as HW flow control for UART 0.
GPIO PushbuttonsPushbuttons PB1 and PB2 connect to P2.6 and P2.7, respectively. Pressing a button pulls the associated port low.
GPIO HeadersSelect GPIOs are accessible through 0.1in spaced head-er pins. The IC provides support for both 1.8V and 3.3V peripherals through power rails VDDIO and VDDIOH. GPIO voltages can be programmed on a pin-by-pin basis. Refer to the MAX78000 programming guide for more detail.
Wakeup InputThe MAX78000 offers multiple low-power and micropow-er operating modes. Wakeup pushbutton SW4 provides a debounced signal to bring the IC back into normal operat-ing mode.
Parallel Camera ModuleThe MAX78000 supports parallel camera interface (PCIF) devices. The included camera module plugs into the EV kit board and uses an OVM7692 integrated camera/lens device.
