| CS8818 |
General Purpose USB2.0-to-ATAPI Bridge Controller with Embedded PHY |
Sampling | | General Description: | The CS8818 is a single chip USB (Universal Serial Bus) 2.0 Mass storage class peripheral controller intended for use with standard ATAPI devices. The device consists of a USB 2.0 PHY and SIE, FIFO buffers, embedded 8-bit single-cycle micro-controller with expanded external program ROM/Flash memory, and ATAPI compatible interface.
The CS8818 uses 12MHz crystal to reduce the EMI issue. With flexible 32-bit I/O interface, the CS8818 can be programmed to fit different situations in the USB 2.0 high speed mass storage class applications such as CD-ROM, CD-RW, DVD-R and DVD-RW, etc. | | Features: |
| • |
Fully compatible with USB specification 2.0
-Support full-speed (12M bits/sec) or high-speed (480M bits/sec) devices with multiple configurations and ultiple interfaces
-Support all USB standard commands, including suspend and resume detection logic
-Support USB 2.0 TEST mode features

| • |
Supports 5 endpoints
-All endpoints share one on-chip 1K bytes SRAM buffer and the size of each endpoint is configurable
-Default control endpoints (EP0) with up to 64-byte buffer on either TX or RX direction
-An interrupt OUT endpoint (EP1) and an interrupt IN endpoint (EP2)
-A bulk OUT endpoint (EP3) and a bulk IN endpoint (EP4): up to 512 bytes data payload for full/high speed bulk endpoint
-Unused endpoint can be disabled
