This pin is always driven by the programmer, and the target system should never attempt to drive this wire when target reset is active.

When programming the AVR in Serial mode, the In-System Programmer supplies data to the target on the MOSI pin. Immediately after the Reset goes active, this pin will be driven to zero by the programmer. When programming the AVR or other SPI chips in Serial mode, the In-System Programmer supplies clock information on the SCK pin. To simplify this operation, the target reset is controlled by the In-System Programmer. When erasing the chip, the reset line has to be toggled to end the erase cycle. The target AVR microcontroller will enter Serial Programming mode only when its reset line is active (low). This is done by connecting ground of the target to ground of the programmer. The in-system programmer and target system need to operate with the same reference voltage.

Verify functions from the software screen.Īccording to the device information box from the software, signal connections should comply with the table below.įollowing is an example pinout of SPI EEPROM:

Operate erase, blank check, and program.

Switch on the target board independent power supply.

Otherwise, VCC should be connected if power is supplied by the ISP cable.

It is recommended that the target board power is supplied independently, especially for target boards with high power consumption and multiple power systems.

If the “mass production" function is to be used, TPIN and TPOUT signal lines should also be connected.

Connect signal lines (including GND) for corresponding interfaces of the ISP programmer with the target board.

Search chip part numbers in the ISP programming software to view operation hint.The programming operation steps are as follows: User can erase, program, verify and read content of SPI EEPROM and Flash memory devices. The Serial Peripheral Interface (SPI) programmer (Superpro IS01 or Gang ISP programmer SuperPro IS03) provides fast programming of any SPI memory device by controlling the SPI bus signals directly through a dedicated high-speed SPI interface on the programmer. SuperPro IS01 Programmer supports high-speed programming of SPI compatible serial EEPROMs and Flash memory devices.
