DESCRIPTION

The µPD70F3015B, 70F3015BY, 70F3017A, and 70F3017AY are products with on-chip flash memory. Because the devices can be programmed by the user on-board, they are ideal for the evaluation stages of system development, small-scale production of a variety of products, and rapid development of new products.

The V850/SA1 provides a high-level cost performance ideal for applications ranging from low-power camcorders and other AV equipment to portable telephone equipment such as cellular phones and personal handyphone systems (PHS).
