It is recommended that the power of the target board is supplied independently, especially for the target board with high power consumption and with multiple power systems. If the above “mass production" function is to be used, TPIN and TPOUT signal lines should also be connected.Ĥ.

Search for the type of the chip to be operated in the ISP programming software and view the Device information dialogue box.Ģ. The programming operation steps are as follows:ġ. The following is the pin out of M24C04 chip:įront view of color coded ISP connector of Let us take an example of M24C04 chip from Microchip in order to understand the connection with ISP cable of Xeltek Otherwise, separate power must be applied to the target PCB. If the device power pin is separated from the circuit, then the programmer power may be applied to the device.Otherwise, signals may clash and proper programming may not be possible. Serial input, Output, and clock pins must be separated from the rest of the circuit and easily accessible externally.The following points should be kept in mind: In order to program any serial EEPROM in-circuit, the PCB has to be designed to be able to program serially. The 24/25x04 are always slavedevices in all communications. The master will always initiate a datatransfer and will provide the serial clock for synchronization. The device that controls thedata transfer is known as the master and the other as the slave.
This protocol defines any device that sends data ontothe bus as a transmitter and any device that reads the data as a receiver.
The 24C04serial EEPROM supports the I2C protocol. Typical voltages used are +5 V or +3.3 V although systems with other voltages are also permitted. Open-drain lines, Serial Data Line (SDA) and Serial Clock (SCL), pulled up with resistors. There are different kinds of serial EEPROM devices which can be categorized on the basis of communication protocol they use forĮEPROM programming through I☬ interface using ISP programmers such as Xeltek IS01. These are small and inexpensive which are extremely useful when a minimum number of I/Os are used. Serial EEPROMs are suitable when a less amount of nonvolatile, read/write memory is needed in a design.
