Now you can fully integrate the TDS2020F 16-bit or the TDS9092 8-bit embedded computer into your application or design a custom-shaped board to suit your exact requirements.

A minimum system only requires a few extra components: all widely available commercially.

Made by Hitachi and MCE (division of Smiths Industries) respectively, the microprocessor contains Forth and symbolic assembler, the gate array extra parallel ports, keyboard scanning facility, watchdog timer, PROM and RAM chip selects and spare address decodes including those for liquid crystal displays.

ORDERING INFORMATION   

It is unlikely that the use of chip sets will be cost-effective in quantities under 500 sets. Use the complete TDS2020F or TDS9092 computer unless you have a special requirement for small space or an unusually-shaped printed circuit board.

Order codes for the 16-bit and 8-bit chip sets are:

FORTHCHIPS2020 comprising:

l       one Hitachi H8/532 microprocessor

l       one TDS9 gate array

l       one licence to use the Forth system

FORTHCHIPS9092 comprising:

l       one Hitachi 6301 masked Forth microprocessor

l       one TDS9 gate array

l       one licence to use the Forth system

As part of the licence you may also use :

l       those parts of the TDS2020F or TDS9092 circuit diagram which are useful in your application

l       those parts of the TDS2020F or TDS9092 PCB layout which are useful in your application

l       any of the library routines provided with these board-level computers

If your need exceeds 5,000 per year we can probably reduce your application PROM and the Forth in ROM to give a consolidated program for masking into a single chip to give even lower costs. The TDS2020F and TDS9092 system is continuous from single unit quantities to large volume consumer uses; you don't have any major redesign as the quantity grows.
