The μPD78094x 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 160 LCD segments. The integration of the high-
speed microcontroller and the CAN controller, together with the high level of integration (using NEC’s
0.35-micron CMOS process technology), make these devices a cost-effective solution for automotive
electronics and industrial control applications needing an LCD display.
In addition to several memory configurations, the μPD78094x microcontrollers have low EMI emissions,
two on-chip oscillator circuits for low-power operation, 256 bytes of EEPROM, and a host of on-chip
peripherals. The system address/data bus allows the use of 56K of internal program memory and 4K of
external program memory. A flash version is available, as is an extensive tool chain containing a
software simulator, C compiler, relocatable assembler, screen debugger, and in-circuit emulator.
