Pericom Semiconductor PT8A977B
The PT8A977B and PT8A9781 provide a complete control functions to the remote-controlled toy. The PT8A9781 has four output pins corresponding with the four actions i.e, forward, backward, right, left. The received signals are amplified by the three-stage amplifier, and then the appropriate amplified signals are sampled, fault-tolerantly checked and decoded to control the actions of the remote-controlled toy.| Part No. | PT8A977B |
