UPD703081 Datasheet | NEC

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 pact code size parable to 16-bit CISC CPUs. The V850/DB1 ("AVALON") offers an excellent bination of general purpose peripheral functions, like serial munication 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 bination 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.
