1 Azoteq USB-dongle usage
The Azoteq USB-dongles available for commercial use are listed in Table 1-1. The dongles are
connected to a computer via a mini-USB cable and are used:
•
As an interface to program OTP
1
bits which is available on certain ICs (to customize an IC for a
certain design), see table Table 3-1 for pin assignment or
•
To perform serial communication between computer and IC via
o
1-wire Communication Protocol see Table 4-1,
o
SPI see Table 4-2,
o
I
2
C see Table 4-3.
Azoteq provides software used for programming OTP bits. This software is known as USBProg and is
intended for prototyping purposes. More information regarding USBProg can be found in application
note AZD007.
Azoteq provides software used for the serial streaming of data to a computer utilising the Azoteq USB-
dongles. This software is known as VisualProxSense and is intended for prototyping purposes. For
some IQS ICs there exists a separate GUI. More information regarding the VisualProxSense application
can be found in application note AZD006.

5 Flash Programming (CT220/CT210 only)
The CT210 supports a programming protocol used to program certain flash MCUs (e.g. IQS550, IQS643
& IQS659). The software used for this purpose is Azoteq Flash Programmer. The pinout to perform flash
programming can be seen in Table 5-1.
