Description
The UPD703014A, 703014AY, 703015A, 703015AY, 703017A, and 703017AY (V850/SA1) are 32-/16-bit singlechip microcontrollers that include the CPU core of the V850 FamilyTM, and peripheral functions such as ROM/RAM, timer/counters, serial interfaces, an A/D converter, a timer, and a DMA controller.
In addition to its high real-time responsiveness and one-clock-pitch execution of instructions, the V850/SA1 includes a hardware multiplier for multiplication instructions, saturation instructions, and bit manipulation instructions, all of which are instructions suited to digital servo control applications. As a real-time control system, this device 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 designing.
