V850/DB1TM AVALON
32-/16-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The V850/DB1 ("AVALON") single chip microcontroller, is a member of NEC's V850 32-bit RISC family, which
match the performance gains attainable with RISC-based controllers to the needs of embedded control
applications. The V850 CPU offers easy pipeline handling and programming, resulting in compact code size
comparable to 16-bit CISC CPUs.
The V850/DB1 ("AVALON") offers an excellent combination of general purpose peripheral functions, like
serial communication interfaces (UART, clocked SI), display drivers, measurement inputs (A/D converter) and
Meter Controller/Driver, with dedicated CAN network support. To support a CAN network, one CAN interface
is implemented on chip.
The device offers power-saving modes to manage the power consumption effectively under varying
conditions.
Thus equipped, the V850/DB1 ("AVALON") is ideally suited for automotive applications especial dashboard. It
is also an excellent choice for other applications where a combination of sophisticated peripheral functions
and CAN network support is required.
Functions in detail are described in the following user’s manuals. Be sure to read these manuals
when you design your systems.
