PD78F0034B, 78F0034BY, 78F0034B(A), 78F0034BY(A)

8-BIT SINGLE-CHIP MICROCONTROLLERS

DESCRIPTION

The

PD78F0034B 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

PD78F0034BY is a member of the

PD780034AY Subseries, featuring flash memory in place of the internal

ROM of the

PD780034AY.

The

PD78F0034B(A) and 78F0034BY(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

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.

78K/0 Series Instruction User’s Manual: U12326E

FEATURES

• Pin-compatible with mask ROM versions (except V

pin)

• Flash memory:

• Supply voltage:

Note

32 KB

Note

= 1.8 to 5.5 V

• Internal high-speed RAM: 1,024 bytes

Note

The flash memory and internal high-speed RAM capacities can be changed with the memory size switching

Remark

For the differences between the flash memory and the mask ROM versions, refer to
