Western Digital WD1402A UART

Western Digital Corporation (often abbreviated to WDC or WD) is one of the largest computer hard disk drive (along with Seagate Technology) manufacturers in the world. It has a long history in the electronics industry as an integrated circuit maker and a storage products company. Western Digital was founded on April 23, 1970 by Alvin B. Phillips, a Motorola employee, as General Digital, initially (and briefly) a manufacturer of MOS test equipment. It rapidly became a speciality semiconductor maker, with start-up capital provided by several individual investors and industrial giant Emerson Electric Company. Around July 1971, it adopted its current name and soon introduced its first product, the WD1402A UART.
