AZD026 USB Dongle
User Manual
Azoteq provides software used for serial streaming of data to a computer by utilizing the Azoteq USB-dongles. Each IC has dedicated software which is intended for prototyping purposes.
Azoteq USB-dongle Usage
The Azoteq USB-dongles available for commercial use are listed in Table 1. The dongles are connected to a computer via a mini-USB (micro-USB for CT210A) cable and are used:
(Please Note: Use with USB data cable only)
- As an interface to program OTP¹ bits which are available on certain ICs (to customize an IC for a certain design), see tables Table 2 and Table 3 for pin assignment or
- to perform serial communication between the computer and IC via
o 1-wire Communication Protocol (Table 5)
o SPI (Table 6)
o I² C (Table 7) - Flash programming (Table 8)
- Bootloader programming (Table 9)
Azoteq provides the software necessary for programming OTP bits. This software is known as USBProg which is intended for prototyping purposes. More information regarding USBProg can be found in application note AZD007.
Azoteq provides software used for serial streaming of data to a computer by utilizing the Azoteq USB-dongles. Each IC has dedicated software which is intended for prototyping purposes. The software is available on the Azoteq website under Software and Tools.
