V850/SV1TM
32-/16-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The µPD703039, 703039Y, 703040, 703040Y, 703041, and 703041Y (collectively known as the V850/SV1) are
products in the low-power series of V850 FamilyTM products, which are NEC’s single-chip microcontrollers for real-
time control.
The V850/SV1 employs the CPU core of the V850 Family, and has on-chip peripheral functions such as large
capacity ROM/RAM, a multi-function timer/counter, serial interface, A/D converter, DMA controller, PWM, and a
Vsync/Hsync separation circuit.
The V850/SV1 not only realizes the low power consumption necessary for applications such as camcorders, but
also extremely high cost performance.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
