ISPPower Mode

ISPDuring programming, the target chip has two power supply modes to choose from. power supply mode can beFlyPROset in the operating options of the software.

⚫powered by programmer

That is, the programmer provides voltage to the target board, and the power supply voltage is3.3Vor5V(existFlyPROset in the operating options of the software). In this mode, if the programmer detects that

the target board power supply already exists, it will give a power supply conflict error message. The programmer comes with an overcurrent detection function, when power is supplied to the target board,

the current is limited to250mA, when the current exceeds this range, overcurrent protection will occur. If the operating current of the target board is greater than250mA, please use the target board self-

powered mode.

⚫Target board self-powered

The programmer in this mode does not supply power to the target board.

SP8The programmer can support an operating voltage range of2.7V~5.5Vtarget board.ISPThe signal drive voltage of the target board will follow theVCCVoltage is automatically adjusted.

ISPimportant

ISPThe implementation of programming is relatively complicated, and it is suitable for people with certain professional knowledge. If only a small number of chips are to be programmed, it is recommended to remove the chips from the

board, and after programming with a conventional programming socket, solder them back to the motherboard. it might be better thanISPway more efficient. When usingISPWhen programming in this way, you must pay attention to the

following matters:

⚫Know the target board circuit diagram (if you haveISPFor consultation on programming related issues, you must provide us with the schematic diagram);

⚫useISPMode burning the chip on the board, all signal pins of the chip must be isolated from other circuits on the board, it must be ensured that the main control chip on the board does

not access the target chip, and all the connections of the main control chip must beIOIt needs to be set to a high-impedance state (the main control chip can be set toRESETstate);

⚫Regardless of the power supply mode used by the target board, the target board'sVCCmust be combined withISPthe first part of the interface2pin connection;

⚫rightISPUnused pins in the interface, please keep them floating, and do not connect with any signal in the target board;

Appendix I Frequently Asked Questions

☺whytwenty fourSerial chip does not have erase function

◼The chip is based onEEPROMtechnology, chip data can be directly rewritten without pre-erasing, so no erase operation is available.

◼To clear the chip data, please write directly to the chipFFHdata can

☺What is the reason for the software prompting chip initialization error?

When programming some chips (such astwenty fourseries chips), the programmer will perform initialization detection on the chip, if the detection fails, it will give the error prompt. Chip

initialization errors usually have the following reasons:

◼The chip is not placed on the locking seat, or the chip pins are not in good contact

◼The chip is placed in the wrong direction or position

◼There is a problem with the chip itself

◼The chip model does not match, that is, the model selected in the software is different from the one actually placed on the locking seat

◼ISPConnection line problem (onlyISPmode, i.e. with [ISP]suffix chip)

☺What is the reason for the programmed chip not working properly?

The programmed chip does not work normally for the following reasons:

◼The data file is not loaded correctly before flashing the chip

◼There is a problem with the data file itself

◼Programming operation step error

◼Chip working circuit/voltage problem

☺Is it possible to program the chips on other circuit boards with the leads on the locking seat?

Can't. It is forbidden to use this method to program the chip, as this method may cause permanent damage to the programmer. The resulting damage to the programmer will not be

covered by the free warranty.

☺Can the burner burn?imgdocument?

The file encoding formats supported by the burner software are binary (binary) and hexadecimal (Inter HEX) formats, the regular suffix of binary files is *.bin,

and the regular suffix of hexadecimal files is *.hex

img is just a file suffix and does not represent the file encoding format. Usually (more than 90%) such files are binary encoding, and can be loaded directly in the software.

The software will automatically identify whether the file is binary encoding and use the recognized format. to load.

In order to ensure the accuracy of file loading, we recommend that users check the buffer checksum and file checksum (in the programmer software) with engineering technicians (or file

code providers/customers, etc.) after loading such files. This information will be displayed at the bottom of the main window).

☺How should the chip configuration bits be set?

All configuration options of the chip are listed according to the specifications of the chip manufacturer, and the user needs to make the correct configuration according to their own project

needs and chip specifications.The programmer is only responsible for writing the data set by the user into the chip, the programmer manufacturer cannot tell the user how to set it, please

contact the project engineer/code provider.

The configuration option is realized by "Write Configuration". In automatic programming (including offline operation/machine operation), the write configuration needs to be added to the last step of the

operation, for example: "Program"→”check"→”write configuration"

SP8 series programmer

☺The programmed chip is soldered to the upper part of the product and cannot run, but it can be re-programmed after soldering it down. Is it because the programmer did not program the chip correctly?

During the final test of the product, it is found that the data in some chips is wrong/or lost/or empty chips. There are many reasons for this. The following

common situations are:

1. When the product is powered on and tested, due to interference, unstable power supply, abnormal access, software malfunction, etc., the chip data will be rewritten or erased.

2. When sorting chips, mix up <put the chip that failed to be programmed, or the chip that has not been programmed to the OK side>

3. The temperature stability of the chip is poor, and data is lost or changed due to high temperature during soldering. According to our statistics, most of the problems are in cases 1 and 2,

and no cases caused by the programmer have been found for the time being. Ensure that the chip data after programming is correct. For the data errors found after high temperature

soldering, the product is powered on and running <chip has been read/written> and other processes, it is not within the scope of the programmer's guarantee.

If you want to rule out or verify if there is a problem with the programmer, it is recommended to do a 100% inspection of the chip before SMD soldering.

For case 1: If the chip is SPI FLASH, there is a way to avoid it, that is, when programming the chip, add a protection function to the chip to

prevent accidental overwriting, see:http://www.sofi-tech.com/html/6184791048.html

☺ISPWhat are the precautions for burning?

The implementation of ISP programming is relatively complicated, and it is suitable for people with certain professional knowledge. If only a small number of chips are to be programmed, it is recommended to remove the chips

from the board, and after programming with a conventional programming socket, solder them back to the motherboard. . This may be more efficient than the ISP method. When using the ISP method to program, you must pay

attention to the following matters:

1. Know the circuit diagram of the target board. <If you have questions about ISP programming, you must provide us with the schematic diagram>

2. When the programmer is programming the target chip, it must be ensured that the main control chip on the board does not access the target chip, and all the connected IOs of the main

control chip must be set to a high-impedance state. <You can try to set the main control chip to for RESET status>

3. Keep the line connection as short as possible. <Some chips may be too long even with the included ISP line>

4. The IOs that are not connected to the chip must meet the normal working conditions of the chip.

For example: HOLD and WP pins of 25 SPI FLASH must be pulled up to high level.

Special attention: ISP programming is to connect from the ISP interface of the programmer (the dedicated interface of the bottom 10pin), and select the model with the [ISP] suffix in the

software (if there is no [ISP] suffix after the chip model, it means no This chip supports ISP programming), please do not connect the cable from the locking socket (40pin socket).
