• Manufacturer Part Number: CS98000-CQ
• Description: Internet DVD (iDVD) Chip Solution
• Manufacturer: Cirrus Logic, Inc.

Notes: 1. Pin may be used for micro-less DVD loader interface
6.2
These pins are used for used for basic functions such
as clock and reset input. The I
master and slave mode (8-bit slave address is 0x30
for write, and 0x31 for read).
6.3
These pins are used to interface the CS98000 with
some external SDRAM. The CS98000 can interface
with SDRAM of various size. Both 16 and 32 bit data
width is supported, but best performance is achieved
with 32 bits. Follow instructions in the following ta-
ble on how to interface any particular configuration
of SDRAM.

6.4
This is the interface to the non-volatile memory that
contains the firmware. It could be either ROM,
NVRAM – FLASH or EEPROM - or any combina-
tion of those. This interface can also connect to
SRAM that would emulate a ROM on a development
system. The bus width is eight or 16 bits. Except for
the NVM_WE_L and NVM_OE_L pins, all these
pins are shared with the DRAM interface, which op-
erates simultaneously with the ROM/NVRAM inter-
face.
