1Introduction
μPD78F8020D is the NEC Electronics 8 bit single chip microcomputer. The
features and hardware specification of Stick LIN-78K0 are described.
1.1 Features
Features of the Stick LIN-78K0 are as follows.
●The evaluation board used the NEC Electronics 8bit single chip microcontroller
μPD78F8020D (The part of 8-bit microcontroller is same as 78K0/KE2). All
of the ROM, RAM, circumference circuit and LIN transceiver are efficiently built
in one chip on a Stick LIN-78K0.
●High-speed operation is realized via the 20MHz internal clock.
●128 Kbytes of Flash EEPROM, available on the chip,
●Stick LIN-78K0 is programmable and debuggable from PC via USB connection
without any additional hardware tools.
●FT2232L (FTDI) is available on board for USB interface (USB2.0 compatible).
●The size of the module is, 82mm x 23mm.

4Power Source
Stick LIN-78K0 are able to choice two ways of power source.
MCU power(VDD) and driver module power(VSUP) are both supplied when power
source are supplied from either USB or expansion interface(VSUP).
If you supply power using the expansion interface(VSUP), then keep power source
voltage DC7.0V-DC18.0V.
