installed, A single 1Mx16 FLASH ROM device is support on the EMI bus. There is also a 2kb I2C serial EEPROM
for storage of user player settings, software configuration information, title specific information, or other purposes.
1.3 DRIVE INTERFACES
The system supports a standard ATAPI drive interface.
The interface to the ATAPI drive is included within the STi5519. The ATAPI data bus is buffered so that the ATAPI
cable does not interfere with signal quality. An ATAPI drive is connected via the standard 34 pin dual row PC style IDE
header
1.4 FRONT PANEL
The front panel is based around an Futaba VFD and a common NEC front panel controller chip, (uPD16311). The
STi5519 controls the uPD16311 using several control signals, (clock, data, chip select). The infra-red remote control
signal is passed directly to the STi5519 for decoding.
1.5 OUTPUTS
There is no separate rear panel for outputs. They are embedded into the mainboard. Supported outputs are:
- Six channel or two channel audio outputs
- Optical and coax S/PDIF outputs are supported
- Composite, S-Video, and SCART outputs
The six video signals used to provide CVBS, S-Video, and RGB are generated by the STi5519's internal video DAC.
The video signals are be buffered by external circuitry.
Six channel audio output by the STi5519 in the form of three I2S (or similar) data streams. The S/PDIF serial stream is
also generated by the STi5519. Three pieces two-channel audio DACs (CS4335) are used for six channel audio
output, and similarly only one CS4335 DAC is used for two channel audio output.
