The μPD78082x devices are high-speed 8-bit microcontrollers with a CAN controller, as well as an LCD
controller capable of controlling and directly driving up to 112 LCD segments. The CAN controller,
together with their high level of integration (using NEC’s 0.35-micron CMOS process technology), makes
the devices a cost-effective solution for many automotive electronics and industrial control applications.
The μPD78082x devices have low EMI emissions, 256 bytes of EEPROM, and a host of on-chip
peripherals. A flash version is also available, as is an extensive tool chain containing a software
simulator, C compiler, relocatable assembler, screen debugger, and in-circuit emulator.
