The V854 is a product of NEC's V850 Family single-chip microcontrollers for real-time control applications. This
chapter briefly outlines the V854.
1.1 General
The V854 is a 32-/16-bit single-chip microcontroller that employs the CPU core of the V850 Family of high-
performance 32-bit single-chip microcontrollers for real-time control applications, and integrates peripheral functions
such as ROM/RAM, real-time pulse unit, serial interface, A/D converter, and PWM.
The V854 is provided with multiplication instructions that are executed with a hardware multiplier, saturated
operation instructions, and bit manipulation instructions that are ideal for digital servo control applications, in addition
to the basic instructions that have a high real-time response speed and can be executed in 1 clock cycle. This
microcontroller can be employed for many applications including real-time control systems such as AV applications
including digital still cameras and camera built-in VCRs; communication applications including portable telephones
and portable information terminals. In any of these applications, the V854 demonstrates an extremely high cost
effectiveness. Especially, the real-time pulse unit that can realize VCR software servo control is provided; therefore,
the system/servo/camera control of camera built-in VCR is realized by one chip.
