5.10 80C51 MCU TOOLS

5.11 KS88 MCU TOOLS

5.12 78K0 MCU TOOLS

Hardware tools

P80C32GBPN chip

MicroTek EASYPACK 8051 serial emulator

Note that the internal chip frequency on evaluation board was 12 MHz, but as 20 MHz versions

are available, this frequency was used for results (execution time values have been divided by

20/12).

Software tools

IAR 8051 assembler

Hardware tools

KS880504 and KS880116 chips

SMDS II in-circuit emulator (Samsung Microcontroller Development System 2) with target boards

TB880504A and TB880116A

A function generator has been used to reach the 8 MHz frequency. It has been connected to the

Personality Board in the SMDS2 emulator after having selected the EXTRA clock source with the

switches in the front panel.

Note that this MCU do not own any internal RAM - register file space excepted. It was also

impossible to emulate external memory. Tests have been performed using register file only.

Software tools

Everything is done from the SMDS operating program software (DOS environment). SAMA

(Samsung Assembler) is used to assemble the programs with the following command line and

options:

SAMA.EXE %S /K /LST

Then, the program is loaded to SMDS2 memory (emulation memory) and a work file is made ([M]

key). The debugging screen is accessed with the [D] key.

Hardware tools

µPD78P014 chip

78K0 starter kit

Note that it was not possible to emulate external RAM.

Software tools

The µPD78P014 toolchain consists of a Micro Series assembler (A78000) and a Micro Series

generic linker (XLINK). The command lines are as follows:

A78000 'name'.asm 'name'.lst

xlink 'name' -o 'name'.o -f bench.xcl

The file bench.xcl extends the length of xlink command line. The extra options included in

bench.xcl are:

-c78000

-Fnec

-Z(CODE)INTVEC=8000

-Z(CODE)CODE=8080

-Z(DATA)DATA=FB00

-Z(DATA)WRKSEG,SHORTAD=FE20-FEDF

-Z(BIT)BITVARS=0

-Y2

The 78K0 starter kit has a DOS environment.
