1. Introduction

This document describes Smart Socket, the next generation programming solution, from Lattice Semiconductor. Smart

Socket replaces the legacy Lattice Model 300 and its associated Socket Adapters. Smart Socket uses the same JTAG-

based Lattice Diamond®Programmer programming software that is used with Lattice Semiconductor’s popular

evaluation and customer boards. Standard ESD environment and procedures should be followed when working with

loose devices and the Smart Socket.

2. Features

Each Smart Socket board is unique for a device family and package. Smart Socket boards have common features such

as:

Powered over simple USB cable

Power switch to remove power from the socket

Integrated FTDI USB interface to work directly with Lattice Programming tools

Power indicator LEDs

Convenient test points

3. Block Diagram

Figure 3.1 shows the high level blocks of a Smart Socket board. The four major blocks on the board are:

USB connector

USB-to-SPI/JTAG communication bridge

Board power regulator

Some product families, such as MachX02, have parts with different core supply voltage requirements. The

Smart Socket board jumper (J2) allows you to select between 1.2 V and 3.3 V core supply voltage. The selected

core supply voltage is indicated by LEDs located next to the jumper on the board.

Lattice Semiconductor Socket (family specific)

A switch controls power to the socket. Three separate LEDs indicate USB power, Socket Power and Programming Done

(Programming Done support varies by device family).

5. Software Requirements

Smart Socket is supported by Lattice Diamond®Programmer. The latest version of the Lattice Diamond Programmer

can be downloaded at:

http://www.latticesemi.com/en/Products/DesignSoftwareAndIP/FPGAandLDS/LatticeDiamond.aspx

Smart Socket works with the Lattice Diamond Programmer using only a USB cable. Connect the cable from the Smart

Socket to a PC, and use the cable search feature in Lattice Diamond Programmer to establish the programming link. The

steps to program a device are described below.

5.1. Generic Programming

To program the device:

1. Launch the Lattice Diamond Programmer software. The Diamond Programmer Getting Started dialog box appears

as shown in Figure 5.1.

Figure 5.1. Getting Started

2. Click OK. The Diamond Programmer automatically starts scanning. The scanning page appears as shown in

Figure 5.2.

When the device scanning is completed, the Diamond Programmer tool shows the device present in socket in the

Device tab. If the Diamond Programmer is unable to identify the device in socket, the device family name is

highlighted with a yellow background under Device as shown in Figure 5.3. Some device families may not support

the scan operation. For details, see the Software Requirements for Specific Device Families section.

Figure 5.3. Unable to Identify Device

In such case, click in the yellow highlighted area and select the appropriate device by matching the device name on

the package with the dropdown list in the Device tab. Select the correct device on the dropdown list, and the

yellow background highlighting disappears as shown in Figure 5.4.

Figure 5.4. Identifying Correct Device

3. Verify that the desired Operation is specified, and update if necessary. To update the operation, select the device

row so that it is highlighted in blue as shown in Figure 5.5. On the menu bar, click Edit, and on the dropdown menu

click Device Properties as shown in Figure 5.5.
