MMWAVE-DEVPACK

1 Getting Started

1.1 Introduction

The MMWAVE-DEVPACK is an add-on board used with TIs mmwave sensor EVMs (1243BOOST,

1443BOOST, and 1642BOOST) to provide more interfaces and PC connectivity to the mmwave sensor

EVM. It provides an interface for the Radar Studio tool to configure the Radar device and capture the raw

ADC data using a capture card, such as the TSW1400.

Key features:

• 120-pin connector to interface with the TSW1400 EVM.

• 20-pin LaunchPad connectors for all the digital controls from the Radar EVM.

• 60-pin high-density (HD) connector for the high-speed ADC data over CSI or LVDS interface and

emulator signals from the BoosterPack.

• Onboard FTDI chip to provide PC interface for SPI, GPIO controls, UART loggers.

• Powered over the micro USB connector.

• 60-pin MIPI connector for JTAG trace (for the 16xx device only).

• Header for DMM interface (for the 16xx device only).

• Second CAN connector (for the 16xx device only).

1.2 Kit Contents

• MMWAVE-DEVPACK

• Micro USB cable to connect to PC.

• Samtec cable to connect the 60-pin high-density connectors of the DevPack and BoosterPack (PN

HQCD⁃030⁃02.00⁃SEU⁃TBR⁃1).

2.2 Connecting the mmwave Sensor BoosterPack to the DevPack

The two boards connect directly over the 20-pin LaunchPad connectors, and the 60-pin HD connectors

are connected using a separate Samtec cable (HQCD⁃030⁃02.00⁃SEU⁃TBR⁃1). The BoosterPack is

always placed above the DevPack. The connectors do not have a key to prevent the misalignment of the

pins or reverse connection. Thus, ensure that reverse mounting does not occur. While connecting the

BoosterPack to DevPack, ensure the pin 1 orientation is correct by matching the 3V3 and 5-V signal

marking on both the boards. Figure 4 illustrates the connection orientation.

2.3 Power Connections

The DevPack is powered by the micro USB cable. However, the onboard LDO is enabled only when the

BoosterPack connected to the DevPack is powered. This is to prevent the DevPack from powering up

before the BoosterPack. This is done by looking for 3.3 V on the PGOOD_3V3 line available J4 connector,

pin#14.

When the two boards are powered, the VBUS LED (DS6) and 3V3 LED (DS7) glow, as shown in Figure 5.

2.4 Connectors

2.4.1 20-Pin BoosterPack Connectors (J5 , J4)

The 20-pin BoosterPack connectors mate directly with the mmwave BoosterPack. The orientation of the

boards while connected must be ensured by matching the 3V3 and 5-V pin markings on both the boards,

as shown in Figure 6.

Figure 6. 20-Pin BoosterPack Connectors

2.4.2 60-Pin High Density (HD) Connector (P3)

The 60-pin HD connector (see Figure 7) provides the high-speed CSI/LVDS data, controls signals (SPI ,

UART, I2C, NRST, NERR, and SOPs), and JTAG debug signals from the BoosterPack. The Trace and

DMM interface lines are also available through this connector.

2.4.3 120-Pin High Density (HD) Connector (J6)

This connector enables interfacing the LVDS signals to the TSW1400 EVM or the CSI, and control signals

to the central processor board, as shown in Figure 8.

Figure 8. 120-Pin TSW EVM Interface Connector

2.4.4 MIPI 60-Pin JTAG Connector (J3)

This connector provides the standard MIPI 60-pin interface for JTAG and trace capability (trace is

available only on the 1642 device), through emulators such as the XDS560pro (see Figure 9). To use this

interface, tlhe JTAG lines to the onboard emulator (XDS110) on the mmwave BoosterPack must be

disconnected. This is done by removing the resistors R69, R70, R71, and R30 from the mmwave BOOST

boards.

2.4.5 TI 14-Pin JTAG Connector (P8)

This connector provides a JTAG interface for debug and development, through emulators such as the

XDS100 (see Figure 10). To use this interface, the JTAG lines to the onboard emulator (XDS110) on the

mmwave BoosterPack must be disconnected. This is done by removing the resistors R69, R70, R71, and

R30 on the mmwave BoosterPacks.

Figure 10. TI 14-Pin JTAG Connector

2.5 PC Connection

Connectivity is provided through the micro USB connector over the onboard FTDI IC. This provides the

following interfaces to the PC:

• FTDI Port A -> SPI interface for radar device control using Radar Studio.

• FTDI Port B-> I2C interface and host INTR signal.

• FTDI Port C -> BSS Logger port (for internal debug only), Nrst control, and Nerror signals.

• FTDI Port D -> DSS Logger port (available only on 1642 device), SOP line control signals, and GPIO

signals

When the USB is connected for the first time to the PC, Windows®maybe not be able to recognize the

device. This is indicated in the device manager with yellow exclamation marks, as shown in Figure 11.
