Other Parts Discussed in Thread: PCA9554 Hi Sir,
We tested some of the noise in the PCA9554 clock signal(SCL) .(as Figure
And these noise happens to occur shock near the VIH.
I would like to ask some question~
1. What would happen when the swing happen…

Hi Matt,
Since the I/O ports are CMOS structures, they need to be held at a valid state. It is recommended that they be pulled up/down through a resistor. See the PCA9554 for the equivalent device with internal pullups so the any unused ports can be left…
Part Number: BQ24610 Other Parts Discussed in Thread: PCA9554 , Hi Team,
I am using BQ24610 for charger application. I am also using PCA9554 (I2C to IO expander) in the same PCB. Is it recommended to use the VREF (3.3V) output from BQ24610 to power the…
Part Number: PCA9554A Other Parts Discussed in Thread: PCA9554 Hi,
I am using the PCA9554ADG in 2 project and I have the same problem in both.
A few second after powering on the board, the PCA9554ADG increase the power supply current and fails. After the…
Other Parts Discussed in Thread: PCA9554 Hi All,
We are using the PCA9554 I2C IO Expander with AM335x processor. It have 8 IO ports and 1 interrupt pin for processor.
One of the IO ex-pander pin will act as interrupt from the Wifi Module. we are configured…
Hi, Keerthy
Our customized board didn't have PCA9554 and PCA953x which are the chip of I2C to I/O expander to collect current and temperature value, will it affect the behaver of the whole system? In the other words, will it cause this kernel to halt…

Hi,
So I'am trying to build a new Linux kernel for a device that has been discontinued by the company. I have extracted the config.gz and DTB using DTC in Linux. This way I made Linux Kernel 4.1.6 via 01.00.00.00 since…
Hi Nick,
Please find the Setup information below.
1. ICSSG1 eth1 -> TI Network (subnet 1)
2. ICSSG1 eth2 -> TI Network (subnet 2)
3. CPSW -> static with Linux PC 1 on 1 (no need for router in between them )
With eth1 and eth2 make sure that…
