Microprocessor trainer Model CNT-IF is an 8085 trainer.
Using this trainer, students studying in, electronics,
electrical, instrumentation, mechanical, chemical engineering
subjects, B.Sc. (electronics, computers, and physics)
laboratory, and polytechnics can learn programming an
8085 Microprocessor. This can be used for designing
prototypes. The instrument is supplied with 2K Memory
(Optional 8K), to the FULL addressable capability of
the 8085 Microprocessor.
There is no need for you to add extra memory. The memory
is distributed as 8K EPROM and 2K (Optional 8K) RAM.
The RAM is provided with battery backup. 3.5V Ni-Cd
battery is used.
Using an on-board 8155(Optional 8255), Input/output
interface experiments can be performed. Several experimental
interface modules can be connected to this trainer.
They are ADC, DAC, Stepper motor, 8-bit switch input,
8-bit LED output, Relay interface module, etc, and many
more are available. The instrument has a 50-pin Flat
Ribbon Cable (FRC) connector, for interfacing Programmable
Peripheral Interface (PPI).
The instrument has 20 keys (Optional 25keys). Using
them standard functions like, store, increment, decrement
a location; move a block, UP / DOWN load to and from
any computer in Intel Hex Format, etc can be performed.
The Microprocessor trainer CNT-IF is designed to teach
the subject of MICROPROCESSOR programming and interfacing
through practical. Essentially designed to teach the
study of:
- Instruction set of 8085.
- Familiarize the components used in typical MICROPROCESSOR
based instruments.
- Design application oriented equipment.
- Design student projects.
- Perform input/output experiments.
- Study the signals generated by the MICROPROCESSOR.
- Learn the art of programming in machine language.
- Design and debugging techniques, etc.
- Mounted on an elegant cabinet.
