3 Quick Start Introduction
3 Quick Start Instruction
This chapter is a quick start guide to connecting the SX-Key/Blitz and programming the SX
microcontroller. Without even knowing how the SX-Key/Blitz and the SX chip work, you should be
able to obtain satisfactory results from the steps that follow.
3.1 Connecting and Downloading to the SX Tech Board
In order to get familiar with how the SX-Key/Blitz Development System works, we’ll use the SX Tech
Board to program and run a 28-pin SX chip.
Keep in mind that the SX Tech Board is not a programmer; rather the SX-Key/Blitz is the
programmer/debugger device while the SX Tech board is a type of prototyping board. Follow these
steps to connect and download a program:

1) Plug an SX28AC/DP into the 28-pin LIF socket on the SX Tech board as shown in Figure 4 - SX Tech
Board with SX chip inserted. Make sure it is oriented so that the half-moon notch in the chip faces
away from the “Reset” button.
