V853
V850 family
32-bit RISC Microcontrolle rs
Product Le tte r
The single-chip V853 microcontroller is a member of NEC’s 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.
De s crip tion
Ap p lications
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.

Functional Block Des cription
CPU
The internal CPU, based on Harvard architechture, is a very compact 32-bit RISC engine.
Most instructions are executed in a single clock cycle under control of a 5-stage pipeline.
It also includes a 16 x 16-bit hardware multiplier with 32-bit result and saturation logic. A
32-bit barrel shifter and bit manipulation instructions accelerate complex bit operations.
Bus Control Unit
(BCU)
The BCU initiates the bus cycles based on the physical addresses generated by the CPU.
When an instruction stored in external memory is executed and no bus cycle initiation is
requested by the CPU, the BCU creates a prefetch address to prefetch an instruction code
which is then inserted in the internal instruction queue.
The internal RAM, with a capacity of 4 or 8 Kbytes, is mapped from address FFFFE000H.
The CPU can access any data in one clock cycle.
RAM
ROM
The internal ROM (96 or 128 Kbytes) or Flash ROM (128 or 256 Kbytes) is mapped from
00000000H. The CPU can access any instruction from the ROM/Flash ROM in one clock cycle.
PROM Programming
Ports
The Flash memory can be written and erased electrically.
The V853 has 67 input/output port pins that can be used alternatively as control pins.
The interrupt controller handles the interrupt request issued by internal peripheral
hardware and external sources. Up to 8 interrupt priority levels can be specified for each
interrupt request.
Inte rrupt Controlle r
The clock generator produces the CPU operating clock. The internal frequency can be
selected as 5x or 1x of crystal frequency by using the internal PLL or 1/2x crystal frequency
without PLL. An external clock can be used instead of the clock generator. A clock-out
signal is available.
Clock Ge ne rator
Re al-time Puls e
The RPU includes a 5-channel 16-bit timer/counter unit.
Unit (RPU)/Time rs
The serial interface includes two channels of CSI (Clocked Serial Interface) and two channels
which can be operated in the UART (Asynchronous Serial Interface) or the CSI mode. The
UART transfers data via the TxD and RxD pins. The baud rate is determined by the on-chip
dedicated baud rate generator. The CSI transfers data via the SO, SI and SCK pins at a baud
rate determined by the on-chip dedicated baud rate generator or an external clock.
Se rial Inte rface
An 8-channel A/D converter with 10-bit resolution and a 2-channel 8-bit D/A converter are
integrated.
A/D Conve rte r
PWM
A 2-channel PWM unit with different operating modes is available on chip.
