This pin should be connected to the MISO pin on the Target Microcontroller. This is the SPI data input pin to the programmer. (except for ATmega103/128/64 – connect to TXD pin instead) It will be driven HIGH/LOW according to the device type and settings in the ‘Pre-program State Machine’ tab in the Eqtools project. This pin controls the Target Device RESET pin. This voltage could be used to power the programmer depending on the settings of the power switch/jumper on the programmer.Ĭommon ground connection between the programmer and Target System. This pin should be connected to the Target System Vcc. This pin should be connected to the MOSI pin on the target microcontroller. Master Out Slave in This is the SPI data output pin from the programmer. (Except for ATMEGA103/128/64 - connect to RXD pin instead) The table below details the pin-out connections of this header

Equinox recommend that the 'Equinox 10-way ISP Header' is considered for any new design as this header is compatible with both Atmel AVR, AT89S and AT89C51Rx2(8051) microcontrollers and also support the 'High-Voltage Serial Programming Mode' of the ATtiny microcontrollers.Ītmel Programmer / Development Board compatability It is highly recommended to use a 'bump polarised' box header to ensure that the ISP Cable cannot be plugged in the wrong way around by mistake.Īlthough this header pin-out is commonly used, it is not the most future-proof choice of pin-out as there are no spare pins to perform other functions. It consist of a 10-way IDC header with the pin-out as shown in the figure to the right. This header supports In-System Programming of Atmel AVR and AT89S microcontrollers using the SPI (Serial Peripheral Interface) protocol. The 'Atmel 10-way ISP Header' is very popular as it was designed onto the Atmel STK200 and STK500 Starter Kit boards. ISP Header - 10-way IDC - Atmel SPI pin-out
