Clone STMicroelectronics ST7FMC1K6BC MCU Heximal

If you want to Clone STMicroelectronics ST7FMC1K6BC MCU Heximal, first of all the status of STMicroelectronics ST7FMC1K6BC MCU must be reset to unlock one and then you can read out its heximal from both eeprom and flash, in order to do that you need to have a clear idea about its internal pin’s definition:

1. If the ICCCLK or ICCDATA pins are only used as outputs in the application, no signal isolation is necessary. As soon as the Programming Tool is plugged to the board, even if an ICC session is not in progress, the ICCCLK and ICCDATA pins are not available for the application. If they are used as inputs by the application, isolation such as a serial resistor has to implemented in case another device forces the signal. Refer to the Programming Tool documentation for recommended resistor values when Clone STMicroelectronics ST7FMC1K6BC MCU Heximal.

2. During the ICC session, the programming tool must control the RESET pin. This can lead to con- flicts between the programming tool and the appli- cation reset circuit if it drives more than 5mA at high level (push pull output or pull-up resistor<1K). A schottky diode can be used to isolate the application RESET circuit in this case. When using a classical RC network with R > 1K or a reset management IC with open drain output and pull-up resistor > 1K, no additional components are need- ed. In all cases the user must ensure that no exter- nal reset is generated by the application during the ICC session.
3. The use of Pin 7 of the ICC connector depends on the Programming Tool architecture. This pin must be connected when using most ST Programming Tools (it is used to monitor the application power supply). Please refer to the Programming Tool manual after Clone STMicroelectronics ST7FMC1K6BC MCU Heximal.

4. Pin 9 has to be connected to the OSC1 or OS- CIN pin of the ST7 when the clock is not available in the application or if the selected clock option is not programmed in the option byte. ST7 devices with multioscillator capability need to have OSC2 grounded in this case if CLONE IC.
