3. On the programmer board is placed 6 pins header to control buffers power supply developer can set jumper in one of three positions ZE _ connected pins 1 and 2 The power supply voltage of the STICK s ICC buffer follows the VDD used by user ST7 This position allows working with any power supply voltage supported by user MCU When the jumper is in this position user must connect the application power supply to pin 7 of the ICC connector connected pins 3 and 4 The power supply voltage of the STICK s ICC buffer is 5 V User don t need to connect the application VDD to pin 7 of the ICC connector but application must be powered by 5 V 5 connected pins 5 and 6 The power supply voltage of the STICK s ICC buffer is 3 3 V User don t need to connect the application VDD to pin 7 of the ICC connector but application must be powered by 3 3 V 5 ion MCU supply voltage STICK supply current min STICK supply current max 5V 15mA 40mA 3 3V 12mA 25mA Tab 1 Electrical characteristic In Circuit Communication protocol ICC allows programming the microcontroller while device is mounted on application board However application board must integrate an ICC connector To connect to user application board for ICPcable Il developer must install a 10 pin HE 10 type connector which receives the ICC cable and relays the required signals to the ST7 on application board Figure 1 HE 10 type connecto

5. resistor lt 1k To avoid such conflicts a Shottky diode can be used to isolate the application reset circuit Pin ICCOSC this ICC connector pin should be connected to OSC1 or OSCIN pin if clock is not provided by the application or if clock source is not programmed in option byte This connection allows starting programming session in ICP OPT Disable mode In this mode programmer is a clock source 8 MHz for microcontroller In case when application board provide clock signal for ST7 and developer is certain that ST7 option byte are programmed correctly ICP session can be started using ICP OPT Enable mode In this mode application clock source provides the clock signal for initiating communication with ST7 and ICCOSC is not connected to ST7 Note When developer wants to use ICCOSC as clock source for microcontroller during programming he should read first datasheet of this microcontroller chapter about programmer connection In some case ICCOSC has to be connected to PB4 CLKIN pin not OSC1 when using ICP OPT Disable mode e g ST7Lite ST7SuperLite Pin VDD APPLI ICPcable II need to be powered from application board this pin should be joined with application power supply Pin ICCSEL VPP this pin is using in ICC protocol and some processors need this line to programming session In ST7Lite processors there are no pins like this ZEM _ ion 5 Programming with STVD7 or STVP7 Developer can configure and
