PD78F0034A, 78F0034AY
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
µ
PD78F0034A is a member of the
µ
PD780034A Subseries in the 78K/0 Series, and is equivalent to the
µ
PD780034A but with flash memory in place of internal ROM.
The
µ
PD78F0034AY is a member of the
µ
PD780034AY Subseries, featuring flash memory in place of the internal
ROM of the
µ
PD780034AY.
The
µ
PD78F0034A incorporates 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.
