Main Features of JTAG Upgrade |
|
- Supports high-speed JTAG programming of a single Atmel AVR microcontroller connected via the JTAG interface
-
Supports high-speed JTAG programming of multiple Atmel AVR microcontrollers which are connected as part of a 'JTAG Chain' (JTAG daisy-chain mode).
-
Fast programming speeds via JTAG (3 - 4 times faster than SPI method)
-
Simple 4-wire JTAG Interface to microcontroller
-
Same JTAG Interface as Atmel JTAG ICE MK2 Debugger
-
User-selectable JTAG frequency
-
Supports JTAG Chain Validation
-
Supports checking of the 'JTAG ID' of both AVR and any generic JTAG devices eg. CPLD's
-
Supports automatic checking of 'Silicon Revision' of target JTAG device
|

Advantages of JTAG Programming |
|
- The JTAG algorithm is approximately 3-4 times faster at programming compared to the SPI algorithm.
-
The programming time using JTAG for the EEPROM is significantly faster than the SPI algorithm
-
The JTAG algorithm uses the same ‘JTAG Port’ as the Atmel JTAG-ICE Debugger.
-
In JTAG mode is it possible to change the ‘Clock Selection Fuses’ to any value and still program the chip. (with the exception of the ‘JTAGEN’ Fuse)
-
It is possible to daisy-chain multiple JTAG devices on the JTAG bus in a so-called ‘JTAG Chain’ and then select to program a particular device in the chain. This functionality is now supported by Equinox programmers running firmware 3.07 and above.

JTAG connections (Single JTAG Device) |
|
|
|
- Supports high-speed JTAG programming of a single Atmel AVR microcontroller
-
Uses only 4 x JTAG pins + control of the AVR RESET pin
-
Uses the same JTAG port pins as used by the Atmel JTAG ICE debugger
|
|
JTAG Chain Programming Support |
|
|
|
- Supports programming of Atmel AVR microcontrollers which are part of a 'JTAG Chain'
-
An individual 'Programming Project' is used to program a specific 'JTAG Device' in the 'JTAG Chain'
-
The algorithm supports 'JTAG Chain' programming of both legacy AVR devices eg. ATmega16 and newer AVR devices eg. ATmega2560 with the devices placed in any order in the JTAG Chain
-
High-speed 'JTAG Chain' programming possible due to optimised algorithms
-
Supports JTAG Chain validation (checks the integrity of the JTAG Chain)
-
Supports checking of the 'JTAG ID' of any other non-AVR JTAG device eg. CPLD in the chain
|
|
ISP Header Pin-out |
|
|
|
- Equinox programmers feature the same 10-way IDC connector as the Atmel JTAG ICE debugger
-
The same JTAG interface can therefore be used for both debugging during the "development phase" and "In-System Programming" during the "production phase"
