µPD78(F)0948/49

8-bit Microcontrolle rs

78K0 CAN family

Prod uct Le tte r

De s cription

The µPD78(F)094x 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.

Applications

Fe ature s

The µPD78(F)094x is suited for dashboard, air conditioning and high-end body controller

applications in the automotive sector. In addition, the device is ideal for applications where CAN

functionality is combined with control-oriented peripherals. In particular, there is full support for

systems connected to an LCD display. Since the LCD output is shared with a general-purpose pin,

non-LCD applications are also covered.
