DESCRIPTION
The
碌
PD70F3015B, 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).
Detailed function descriptions are provided in the following user's manuals. Be sure to read them before
