context_page_description: The NEC μCOM series is a series of microprocessors and microcontrollers manufactured by NEC in the 1970s and 1980s.
context_section_description: The μCOM series has its roots in one of the world's earliest microprocessor chipsets, the two-chip processor µPD707 / µPD708. Early in 1970, Coca Cola Japan set out to increase the efficiency of their sales outlets by introducing new POS terminals. Sharp was contracted to build these terminals, and NEC in turn to develop a chipset. The chipset development was complete in December 1971, at about the same time as other early microprocessors in the USA.
  Since then, NEC has developed and manufactured various microprocessors and microcontrollers. General-purpose products among them were given series names starting with μCOM. The μCOM-4 series (4 bit) and μCOM-16 series (16 bit) were original developments, while the μCOM-8 series (8 bit and 16 bit) consisted mostly of Intel- and Zilog-compatible microprocessors.
  The μCOM name disappeared when the V series and 78K series appeared in the 1980s, and the μCOM-87AD series, for example, came to be described simply as the 87AD series.
