Topview Device Programmer

Topview Device Programmer

Even though we had many products before this one, only after launching this, we became known to the embedded system community of India. We gave a good programming tool with an attractive and unmatched cost. The launch price was Rs 2002, the figure matching the year we started selling this. At that time, even programmers costing many times more didn’t come with similar features. To give buyers confidence, we started selling these programmers with a 15 days Money back-Guarantee, which was a new idea at that time. We also kept all details on line for the users’ evaluation. The combination of all these things made this device programmer very popular with the users and it became an instant hit for us.

Even after selling few thousands of this programmer, we never had any customer returning this programmer to get his/her money back.

We still come across customers who talk fondly about this programmer and there are good number of customers who started their career using this programmer.

We are really very happy about this Device Programmer, right from the day of its design till now. Now, we stopped manufacturing them.

Here comes more details about this programmer………..

Topview Device Programmer.

Topview Device Programmer supports all the devices in 8031 family of Atmel, AT89CXX. The programmer supports both parallel and SPI programming for user’s convenience. A powerful windows based GUI facility is available. Apart from this, many new features are made available to make the programming task an easy one.

Supported Devices:
20 Pins:
AT89C1051,AT89C1051U, AT89C2051, AT89C4051.

40 Pins:
AT89C51, AT89LV51, AT89S51, AT89LS51, AT89C52, AT89LV52, AT89S52, AT89LS52, AT89C55, AT89LV55, AT89S53, AT89LS53 AT89S8252, AT89LS8252.

Programmer can be connected to the PC through the serial port : COM1 to COM4

Supports both Parallel and SPI Programming.

Facility is available to program the device soldered in the target hardware through SPI bus. This facility is available in devices: AT89S51, AT89LS51, AT89S52, AT89LS52, AT89S8252, AT89LS8252, AT89S53, AT89LS53.

A single 40 pin ZIF socket is there for programming both 20 pin and 40 pin devices.

Programmer comes with suitable power supply and all relevant cables and is ready for usage immediately after opening the pack.

User Feedback

The unit is working fine. The software interface supplied with this is very user friendly and powerful.

I should congratulate Frontline Electronics for supplying such a fine product.

I could see the professional touch in all respects (right from documents on software to PCB finish).


Your product is superb. I appreciate the workmanship and the choice of electronic components for the product.

Really you and your engineers have done a good job for the embedded system designers.

The programmer is really an engineer’s choice for its price, size and ease of using.

Subrata Bhattacharya,

Graphic user interface facility is good compared to other programmers.

Colour syntax gives better effect in viewing the program code.

Program read option from microcontroller is useful. It also makes us feel convenient since it generates equivalent assembly code.

Programmer is compact and easy to use. the provision of reset key is useful since it is not necessary to switch off the power supply as in case of other programmers.

The user manual provides sufficient exposure to handle programmer efficiently and use the software to maximum extent.

The cost is cheap compared to other programmers. It is 50% less than compared to others.

Few chips, which were rejected by other programmers, have been able to be programmed by this programmer.

Edit EEPROM buffer, Single byte programmer option is one of its kind.

Protecting device, device options, auto-programming mode, read EEPROM, clear EEPROM, all are good.

Dr.Raja Paul Perinbam,

Very Good hardware. Very user friendly software.

GUI facility: Up-to date techniques.

Ease of use: Menu driven and self-explanatory. I will recommend this to my colleagues and friends.


Nice Hardware. Nice Software. Very easy. Very supportive.


Hardware is Ok. Good Software. Excellent GUI facility. Can be easily used.

Dr.Jagdale Shirish Hari,
Karad, Maharashtra.

Hardware is very clean. Good documentation. The programmer is very good. Unique facility to program the in-built EEPROM in AT89S8252 and SPI interface.
