T5BS4-9999 brief introduction:
T5BS4-9999 is a 16-bit high-speed micro-controller that is used for the control of a variety of
small to large devices. T5BS4-9999 could extend ROM and is an IC with 64 pins and is
packaged in PLCCC. It is the main control IC of the TV and implements I²C bus control of the
overall system.
