Description
V853
32-bit RISC Microcontrollers
The single-chip V853 microcontroller is a member of NEC鈥檚 32-bit RISC V850 family.
It integrates CPU, ROM, RAM and peripheral functions on chip. The internal bus is 32 bits
wide, the external bus 16 bits wide. Controller memory options are listed in Table 1.
Applications
Like other V850 series controllers, the V853 device is used for real-time control
applications, such as servo motor control in computer peripherals and machine tools, for
engine management control, consumer electronics and multimedia. Flash memory, a variety
of serial communication channels and AD/DA converters make it the perfect choice for
compact communication terminals and complete control systems. Typical benefits of Flash
memory are individually programmed devices in the final production process and field
upgradability. With their low power consumption and power-saving modes, V853 devices
are also ideal for portable applications.
