P MICROCONTROLLERS DESCRIPTION The µPD78F0034B is a member of the µPD780034A Subseries in the 78K/0 Series, and is equivalent to the µPD780034A (expanded-specification product) but with flash memory in place of internal ROM. The µPD78F0034BY is a member of the µPD780034AY Subseries, featuring flash memory in place of the internal ROM of the µPD780034AY. The µPD78F0034B(A) and 78F0034BY(A) are products to which a quality assurance program more stringent than that used for the µPD78F0034B and 78F0034BY (standard models) is applied (NEC Electronics classifies these products as "special" quality grade models).
