DATA SHEET
MOS INTEGRATED CIRCUIT
µPD70F3003A, 70F3025A
V853TM
32-/16-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD70F3003A and µPD70F3025A have a flash memory instead of the internal mask ROM of the µPD703003A/
703004A and µPD703025A, respectively. This model is useful for small-scale production of a variety of application
sets or early start of production since the program can be written and erased by the user even with the µPD70F3003
mounted on the board.
Functions in detail are described in the following user’s manuals. Be sure to read these manuals when
you design your systems.
V853 User’s Manual-Hardware
: U10913E
V850 FamilyTM User’s Manual-Architecture : U10243E
FEATURES
• Compatible with µPD703003A, 703004A and 703025A
• Can be replaced with mask ROM model for mass production of application set
