DATA SHEET  
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.

78K/0 Series Instruction User’s Manual: U12326E  
FEATURES  
Pin-compatible with mask ROM versions (except VPP pin)  
Flash memory:  
32 KBNote  
Internal high-speed RAM: 1,024 bytesNote  
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  
register (IMS).  
Remark For the differences between the flash memory and the mask ROM versions, refer to 4. DIFFERENCES  
BETWEEN µPD78F0034B, 78F0034BY, AND MASK ROM VERSIONS.
