First steps towards THC design (UPDATEx2)
Esden
On last thursday I started with drawing the schematic for THC. I also worked on weekend on it and now I have pretty many things wired in the schematic.
This is the list of devices that are already in the schematic and wired:
- S3C44B0X (Main processor)
- SST39VF320 (ROM)
- HY57V641620HG (RAM)
- Power supply (wall plug)
- RTC power supply with battery
- JTAG plug
- Reset circuit
- Main system oscilator circuit
- RTC oscilator circuit
- RS232 serial IO
- Bluenicecom BlueTooth interface board (based on LMX9829 chip)
- UDA1341TS (Sound interface)
What is still missing:
- Key interface
- Display controller (will probably be the Lime chip by Fujitsu)
- Display
- Battery power supply
- SD Cardreader
- Speakers
After I have made the schematics for the missing parts I think I will be able to start designing the PCB.
I am pretty happy with the progress till now. If you have any specific questions do not hesitate and write me. ;)
UPDATE: Added SD Cardreader to missing parts UPDATE2: Added Speakers to missing parts
