Max current = 300 mA.
18 Target
SPI
Frequency
The programmer supports three SPI speeds:
•
SLOW SPI: 0 – 490.2 kHz (user selectable)
•
MEDIUM SPI: 0 – 490.2 kHz (user selectable)
•
FAST
SPI:
Disabled
( SPI speeds are estimations only due to uneven mark/space
ratio and non-continuous waveforms)
19 Target
JTAG
Frequency
The programmer supports a user-defined JTAG frequency:
•
SLOW: 0 – 833 kHz
20 Target UART Speed
•
This is the Communications Speed (BAUD rate) from the
programmer to the Target Device when communicating
via a Boot Loader.
•
The BAUD rate is configurable from 1,200 to 115 kBaud.
•
This settings is completely independent from the BAUD
rate settings for the PC communicating with the
programmer.
21 ISP
Headers
The programmer support all the popular ISP Header as standard:
•
Atmel 10-way (SPI)
•
Atmel 6-way (SPI)
•
Atmel 10-way (JTAG)
•
Equinox 10-way (SPI+UART)

22 Frequency
generator
output (SCK2)
The FS2003 is capable of outputting a continuous square wave
at various frequencies on the programmer SCK2 pin.
The following pre-set frequencies can be selected via the
EQTools Programming Project:
1.8432 MHz, 921.6 kHz, 614.4 kHz, 460.9 kHz, 386.6 kHz, 307.6
kHz, 230.4 kHz,167.6 kHz, 102.4 kHz, 51.2 kHz
This clock frequency could be used for the following purposes:
•
To toggle the STROBE pin on a Watchdog Timer IC to
stop the IC from timing out during the In-System
Programming operation.
•
To provide a clock to an Atmel ATmega microcontroller to
resurrect a device which has an incorrectly configured
Internal Oscillator.
Please refer to the ‘EQTools – Getting Started Guide’ for full
details of setting up the SCK2 oscillator.
23 Target
Run
The programmer is capable of automatically running firmware
which has been programmed into a Target Device and waiting
until the MISO pin is asserted by the Target Device.
24 Pre-Programming
State Machine
The programmer has 5-state ‘Pre-programming State Machine’
which allows the I/O lines of the programmer to be sequenced in
order to place the Target Device into Serial Programming Mode.
25 PC Connection
RS232 – Single Programmer Channel Control
