EclaireXL

"eclaire XL" Atari Hardware Board Specifications

1. Three 600mA step down DC to DC converters at 3v3, 2v5 and 1v1 volt.

2. Altera "Cyclone V" latest family FPGA, include 224 I/O, 25.000 logic elements, 2 MB internal ram, 28nm low power 1v1 volt process technology, which give up to 40% lower power consumption from the previous generations.

4. CMOS output 50 MHz crystall to feed the FPGA.

3. On board 32 MByte high speed CMOS SDRAM, working till 166MHz.

4. 8-bit CMOS Digital to Analogue video converter, with 180 million samples per second.

4a. This support VGA, S-Video, and Composite Video outputs.

5. 16 MByte Serial Flash Memory, with 108 MHz serial bus interface.

5a. This will give us the oportunity to include more than one Core configuration on board, as to be possible to selected within a screen menu. So no more reprogramming whenever someone need to work in a different machine, on the same hardware. Minimum example configuration, Atari 800XL and Atari 5200 console!!

6. 10-bit/1-channel Analogue to Digital CMOS converter, used for audio input application.

7. Delta-Sigma audio filter before the line output.

8. RS 232 serial port for developers. RX-TX indication leds are also included. One input and two outputs are available on D-Sub connector.

9. All the needed electronic components to support joysticks, paddles, tablet, SIO port, Cartridge port, PBI port, on board.

10. Independent polyfuses on every connector which have the ability to supply 5 volt external power. The same for the Main Board power-in supply.

11. 5v0-3v3-1v1 voltage test points, to check for accuracy with a multi meter.

11a. Three leds as optical indication for "Power Good" of above 3 voltages.

MainBoard I/O

1. SD card socket, Push-Push insert/extract type.

2. Two 9 pole D-Sub ports for Joysticks, paddles, tablet.

3. Two USB ports for peripherals.

4. 3.5mm Stereo phone jack for audio output.

5. 9 pole D-Sub RS-232 serial port with RX/TX leds, for developers.

6. 4 pole Mini Din connector which support Composite and S-Video outputs. Output can be selected from a 2 position jumper behind it.

7. 15 pole in 3 rows standard VGA connector.

8. HDMI connector. It's function is still in development.

9. 10 pole IDC connector for interconnection with sub board, for SIO output.

10. 40 pole IDC connector for interconnection with sub board, for PBI/Cartridge output.

11. 40 and 14 pole IDC connectors, with 46 total general purpose I/O's, plus 5V0 and 3V3 volt supply. This is for any future upgrade, as for example 2 more joystick outputs.

12. 10 pole "JTAG" IDC connector, for programming of newer firmwares in flash memory.

13. 10 pole "USB_A_B" IDC connector, compatible with those in ITX cases, as found on front panel fascia. This provide two USB ports.

14. 10 pole "AC97_AUDIO" IDC connector, compatible with those in ITX cases, as found on front panel fascia. This provide stereo audio output, and microphone input.

15. "Reset" and "Power Led" 2+2 pole connectors, compatible with those in ITX cases, as found on front panel fascia.

16. Power supply 2 pole connector, for interconnection with the sub bord, for 5 volt power input.

Sub Board I/O

1. USB type B connector for power input. This prevents total damage by wrong polarity, and easy of use.

2. Original Atari rocker switch. Why? Just because.....

3. SIO port with 5 volt output supply and 5 volt motor control, to have different polyfuses for overload protection.

4. Cartridge port, polyfuse protected.

5. PBI 50 pin IDC connector, with the most needed signals used on known existed peripherals. 5 volt supply polyfuse protected supported.

6. 10 pole IDC connector for interconnection with main board SIO connector.

7. 40 pole IDC connector for interconnection with main board PBI/Cartridge connector.

8. 2 pole power connector for interconnection with same connector of main board.

9. 3 support holes to screw within spacers in the main board. This is designed to placed accurate above the back plate connectors of main board.
