DESCRIPTION
The
µ
PD78F0034B is a member of the
µ
PD780034A Subseries in the 78K/0 Series, and is equivalent to the
µ
PD780034A (expanded-specification product) but with flash memory in place of internal ROM.
The
µ
PD78F0034BY is a member of the
µ
PD780034AY Subseries, featuring flash memory in place of the internal
ROM of the
µ
PD780034AY.
The
µ
PD78F0034B(A) and 78F0034BY(A) are products to which a quality assurance program more stringent than
that used for the
µ
PD78F0034B and 78F0034BY (standard models) is applied (NEC Electronics classifies these
products as "special" quality grade models).
The
µ
PD78F0034B, 78F0034BY, 78F0034B(A), and 78F0034BY(A) incorporate flash memory, which can be
programmed and erased while mounted on the board.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
