Development Platform 1 Introduction Thank you for choosing Silego Technology products. The GreenPAK Advanced Development Platform allows you to develop your custom design using GreenPAK mixed signal ICs. You can design your own projects starting from a blank project or by...
2 Getting Started 2.1 Introduction This chapter describes how to install and configure the GreenPAK Advanced Development Platform. Chapter 3 provides the details of hardware operation. Chapter 4 provides instructions on how to create a simple project example. 2.2 Install Hardware No hardware installation is required for this platform.
Note: All test points were designed only for observation of signals on the pins. Please do not try to connect external power/signal source to test points, this will affect GreenPAK Advanced Development Platform functionality and may even damage it. Silego Technology Inc.
3.2.6 Socket Connector The GreenPAK Advanced Development Platform should be used with a detachable socket board. Its main purpose is to connect the GreenPAK chip to the Development Platform. It‘s easy to use the programmed chip in external circuits, or to measure current consumption of the project.
3.2.7 Expansion Connector This port was designed to connect the GreenPAK Advanced Development Platform to external circuits and apply external power, signal sources and loads. It can be used to apply the GreenPAK chip into your custom design with minimal additional tools. For schematic diagram refer to Figure 3.

When the Test mode button is pressed the software will first read the chip to verify if it was inserted and then configure the GreenPAK Advanced Development Platform as set in Emulation Tool window. When the Test mode button is gray then the Development Platform is in Default state and all expansion port switches are open (disconnected).

GreenPAK Advanced Development Platform The GreenPAK Advanced Development Platform provides three possible ways of using expansion connector: 1) Internal power is used to run the chip, no external power output is needed, external signal sources and loads can be connected between pins and GND.
Figure 8. Expansion Connector. Pin with Protection Resistor 3.2.8 Pins Connectivity The GreenPAK Advanced Development Platform supports connecting eight types of loads and signal sources. Each source has its own special purpose. The List of available connections for each test point is presented in the table below.
