OVERVIEW
ISP ATMEL PROGRAMMER
This programmer is based on USBasp design and connects to your computer's USB port. Not
only is it quite compact, but the design is really elegent. The USB interface is achieved by using
an atmega processor and the rest is done in firmware. ISP programmer supports Atmel and
Atmega microcontrollers. It is a reliable tool for fast programming of Atmel and
Atmega device• Simple Three-wire SPI Programming Interface

FEATURES
 Allows you to read or write the microcontroller EEPROM, firmware, fuse bits and lock
bits
 Support for Windows, Mac OS X and Linux
 5 KB/sec maximum write speed
 10 pin ISP interface
ABOUT ISP ATMEL PROGRAMMER
HARDWARE DESIGN CONSIDERATIONS
GND: The In-System Programmer and target system need to operate with the same reference
voltage.This is done by connecting groundof the target to ground of the programmer.
RESET:The target microcontroller will enter Serial Programming mode only when its reset line
is active (low). When erasing the chip, the reset line has to be toggled to end the erase cycle. To
simplify this operation it is recommended that target reset can be controlled by the In System
Programmer.
SCK: When the target microcontroller reset is active, this line should be controlled by the ISP
Programmer. Edges on this line after Reset is pulled low will be critical, and cause the target
microcontroller to loose synchronization with the programmer. When programming, oscillations
on this pin should be tolerated by the surrounding system .

MOSI: When the target microcontroller Reset is active, this line should be controlled by the ISP
Programmer. When programming, oscillations on this pin should be tolerated by the surrounding
system when the Reset is active.
MISO: When the target microcontroller Reset is active, this line should be allowed to become
an output. When programming, oscillations on this pin should be tolerated by the surrounding
system when the Reset is active.
VCC: Allow the In-System Programmer to draw power from the target system, to adapt to any
allowed target voltage. The maximum current needed to power the programmer will vary
depending on the programmer being used.
