MOS INTEGRATED CIRCUIT

µPD78F0034B, 78F0034BY, 78F0034B(A), 78F0034BY(A)

8-BIT SINGLE-CHIP 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).

The µPD78F0034B, 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.

µPD780024A, 780034A, 780024AY, 780034AY Subseries User’s Manual: U14046E

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

FEATURES

•

Pin-compatible with mask ROM versions (except VPP pin)

Flash memory:

32 KB^Note

Internal high-speed RAM: 1,024 bytes^Note

Supply voltage: VDD = 1.8 to 5.5 V

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 4. DIFFERENCES

BETWEEN µPD78F0034B, 78F0034BY, AND MASK ROM VERSIONS.
