DescriptionThe 78F0034B(A) is a member of the PD780034A Subseries in the 78K/0 Series, and is equivalent to the PD780034A (expanded-specification product) but with flash memory in place of internal ROM.
The 78F0034B(A) is a member of the PD780034AY Subseries, featuring flash memory in place of the internal ROM of the PD780034AY.
The 78F0034B(A) are products to which a quality assurance program more stringent than that used for the PD78F0034B and 78F0034BY (standard models) is applied (NEC Electronics classifies these products as "special" quality grade models).
The 78F0034B(A) incorporate flash memory, which can be programmed and erased while mounted on the board.
Detailed function descriptions of the 78F0034B(A) are provided in the following user's manuals. Be sure to read them before designing. PD780024A, 780034A, 780024AY, 780034AY Subseries User's Manual: U14046E 78K/0 Series Instruction User's Manual: U12326E
