Description

      The 75068(A) is a member of the 75X series of 4-bit single-chip microcomputers.

      The minimum instruction execution time of the UPD75068's CPU is 0.95 ?s.  In addition to this high-speed capability, the chip contains an A/D converter and furnishes high-performance functions such as the serial bus interface (SBI) function compliant with the NEC standard format, providing powerful features and high UPD75068(A) is a high-reliability version of the UPD75068. cost performance.  The  UPD75068(A) is a high-reliability version of the UPD75068.

      NEC also provides PROM versions suitable for small-scale production or evaluation samples in system UPD75P068 is the PROM version for the UPD75064, 75066, 75068, and the  UPD75P068(A) development.  The is that for the UPD75064(A), 75066(A), 75068(A).

      The detailed function descriptions are described in the document below.  Please make sure to read this document before starting design.
