CS8818 Overview
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 microprocessor with expanded external program ROM/Flash memory, and ATAPI patible interface. The CS8818 uses 12MHz crystal to reduce the EMI issue.
CS8818 Key Features
- Fully patible with USB specification 2.0
- Support full-speed (12M bits/sec) or high-speed (480M bits/sec) devices with multiple configurations and multiple interf
- Support all USB standard mands, including suspend and resume detection logic
- Support USB 2.0 TEST mode features
- Supports 5 endpoints
- All endpoints share one on-chip 4K 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
