1. Compliant with USB specification revision 2.0, backward compatible with USB specification revision 1.1 2. Support 4/3/2 downstream ports through I/O pin configuration 3. Upstream port supports high-speed (HS) and full-speed (FS) traffic, downstream port supports HS, FS and low-speed (LS) traffic 4. 1 control pipe (endpoint 0, 64-byte data payload) and 1 interrupt pipe (endpoint 1, 1-byte data payload) 5. On-chip 8-bit microprocessor, RISC-like architecture, USB optimized instruction set 6. Performance: 6 MIPS@12MHz 7. With 64-byte RAM and 2K Mask ROM 8. Support customized PID, VID, and support downstream port configuration by reading external EEPROM 9. Low power consumption, built-in 5V to 3.3V regulator 10. Each downstream port supports two-color status indicators, and its automatic and manual modes are compliant with USB specification revision 2.0 11. Built-in upstream 1.5K pull-up and downstream 15K pull-down 12. Embedded serial resistor for USB signal 13. Supports separate and joint modes of power management and overcurrent detection of downstream ports 14. Power enable pin supports low/high enable power switch 15. Complies with bus power requirements 16. Automatically switches between self-powered and bus-powered modes 17. Supports composite devices through I/O pin configuration (downstream ports are not removable) 18. Built-in PLL supports external 12MHz crystal/oscillator clock input 19. Improved output driver through slew rate control to reduce EMI, internal power failure detection to recover ESD 20.
