描述 Description

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.FEATURES
