78K0 CAN family
Product Letter
The μPD78(F)081x with an on-chip CAN interface is a member of a new branch of NEC’s 78K0
8-bit microcomputer family. Based on 0.35 mm technology, the devices integrate powerful
application-specific peripherals in combination with EEPROM and Flash memory technology.
They offer outstanding perspectives and opportunities for system solutions at an excellent price/
performance ratio. There are now over 120 different devices in NEC’s established and powerful
78K0 8-bit microcomputer family. All new products will be offered as mask ROM and Flash EPROM.
The μPD78(F)081x is suited for body controller applications in the automotive sector like door,
mirror, roof-modules, seat/climate control and low end airbag solutions. In addition, the device is
ideal for industrial applications like security systems or intelligent office control where CAN
functionality is required.
