GENERAL DESCRIPTION
64-byte buffer on either TX or RX direction
The CS8818 is a single chip USB (Universal Serial Bus)
- An interrupt OUT endpoint (EP1) and an
2.0 Mass storage class peripheral controller intended for
interrupt IN endpoint (EP2)
use with standard ATAPI devices. The device consists of
- A bulk OUT endpoint (EP3) and a bulk IN
a USB 2.0 PHY and SIE, FIFO buffers, embedded
endpoint (EP4): up to 512 bytes data payload for microprocessor with expanded external program
full/high speed bulk endpoint
ROM/Flash memory, and ATAPI compatible interface.
- Unused endpoint can be disabled
• Embedded USB 2.0 transceiver
The CS8818 uses 12MHz crystal to reduce the EMI
- Integrated bit stuffing/unstuffing and stuff
issue. With flexible 32-bit I/O interface, the CS8818
error detection
can be programmed to fit different situations in the
- NRZI (Non-Return-to-Zero Inverted)
USB 2.0 high speed mass storage class applications
encoding/decoding
such as CD-ROM, CD-RW, DVD-R and DVD-RW, etc.
• USB Mass Storage Class Bulk-Only
Specification Compliant (Version 1.0)
• Support Bus Powered and Self Powered modes
• Support multiple LUNs
• Automatic detection of Master or Slave ATAPI
devices
• Support true ATAPI compatible interface
- Complies with ATAPI-7 Specification (PIO
mode 0,3,4, Multiword DMA mode 0~2,
UDMA mode 0~6)
- 8-bit/16-bit Standard PIO mode interface
- 16-bit Multiword DMA mode and UDMA mode
w interface (Ultra 133)
• ATAPI bus can be shared with other devices
w • Embedded 8-bit microprocessor with on-chip 8K
w x 14 program ROM and optional external 16K x
14 program ROM/Flash memory
.D• Flexible 32-bit I/O interfaces providing maximum
versatility with ROM mask changeable firmware
