Refimprove date August 2010 The Open JTAG project is an Open Source project released under GNU License. It is a complete hardware and software JTAG reference design, based on a simple hardware composed by a FTDI FT245 USB front end and an Altera EPM570 MAX II CPLD . The capabilities of this hardware configuration make the Open JTAG device able to output TCK signals at 24 MHz using macro instructions sent from the host end. The scope is to give the community a JTAG device not based on the PC parallel port Open JTAG uses the USB channel to communicate with the internal CPLD, sending macro instructions as fast as possible.

Unreferenced stub auto yes date December 2009 In System Programming ISP is the ability of some programmable logic device s, microcontroller s, and other programmable electronic chips to be programmed while installed in a complete system, rather than requiring the chip to be programmed prior to installing it into the system. The primary advantage of this feature is that it allows manufacturers of electronic devices to integrate programming and testing into a single production phase, rather than requiring a separate programming stage prior to assembling the system. This may allow manufacturers to program the chips in their own system s production line instead of buying preprogrammed chips from a manufacturer or distributor, making it feasible to apply code or design changes in the middle of a production run. Typically, chips supporting ISP have internal circuitry to generate any necessary programming voltage from the system s normal supply voltage, and communicate with the programmer via a serial protocol. Most programmable logic devices use a variant of the JTAG protocol for ISP, in order to facilitate easier integration with automated testing procedures. Other devices usually use proprietary protocols or protocols defined by older standards. In systems complex enough to require moderately large glue logic , designers may implement a JTAG controlled programming subsystem for non JTAG devices such as flash memory and microcontrollers, allowing the entire programming and test procedure to be accomplished under the control of a single protocol. An example of devices using ISP is the Atmel AVR AVR line of micro controllers by Atmel such as the ATmega Basic families ATmega series.
