Yes. The UCD90xxx has a security feature to protect against unintended or unauthorized flash write. You can turn on security by using the Fusion GUI (the security option is only available when the Fusion GUI connects to an online device), or by sending…
Only one host at a time. Communication is corrupted when more than one PMBus hosts try to send information at the same time. The USB-to-GPIO adapter is a PMBus host.

Yes, the SMBus & SAA Tool allows you to communicate to any I 2C or PMBus device. The tool can be launched from either:
• Fusion Digital Power Designer GUI (Tools → SMBus & SAA Tool)
• Fusion Digital Power Designer → Tools → SMBus & I2C & SAA Debug…
The UCD90xxx PMBus Command Reference contains mostly manufacturer specific commands (see UCD90xxx Sequencer and System Health Controller PMBus Command Reference ).
There are also many standard PMBus commands described in PMBus Specification Rev 1.1…
Not necessarily, and it is up to what you plan to do. However, do use it as an ultimate reference. Each function in the Fusion GUI has a corresponding PMBus command. The UCD90xxx PMBus Command Reference contains not only protocol information but also…
Definitely.
The Fusion Digital Power Designer GUI serves three major functions:
1. Assist you to configure the device with a graphic interface so that you do not have to learn the PMBus commands 2. Generate configuration files and scripts for manufacturing…
Yes. You can configure the USB-to-GPIO adapter to select different bus speed (100 kHz or 400 kHz), packet error checking (enabled or disabled), and pullup settings (open-drain, 668 Ω, 1 kΩ, and 2.2 kΩ).
When the adapter is used on TI UCD90xxx EVMs…
Other Parts Discussed in Thread: UCD90320U , UCD90320 , UCD90240 An ALERT signal is an interrupt line for devices that want to trade their ability to master for a pin. ALERT is a wired-AND signal as SCL/SDA. A slave-only device can signal the host through…
UCD90xxx devices use PMBus communication. Both configuration and monitoring use the same PMBus interface. UCD90xxx devices are PMBus slaves, so you need to have a PMBus host to communicate with them. This PMBus host can be an MCU or FPGA implementation…
