TSB43DA42AZHCR Overview
It is available in the 196-LBGA package. The packaging is shaped in a Tape & Reel (TR)-shape, which makes it easy to carry around. Regulating the temperature to -20°C~85°C is crucial to ensuring reliable operation. If you use a 1.5V 3.3VV power supply, you should have no problem. A 196 termination can be found in it. TSB43DA42 numbers are members of the family. There are 196 pins used in order to operate the device. I have found that this gadget has a total of PCI BUS CONTROLLER uPs/uCs/peripheral ICs in total. At the time of writing, the clock of this device is running at a frequency of 33MHz.
