GL852G-OHY60 创惟科技芯片 QFN-28封装

FEATURES

      ■ Compliant to USB specification Revision 2.0

　　■4 downstream ports

　　■Upstream port supports both high-speed (HS) and full-speed (FS) traffic

　　■Downstream ports support HS, FS, and low-speed (LS) traffic

　　■1 control pipe (endpoint 0, 64-byte data payload) and 1 interrupt pipe (endpoint 1, 1-byte data payload)

　　■Backward compatible to USB specification Revision 1.1

　　■On-chip 8-bit micro-processor

　　■RISC-like architecture

　　■USB optimized instruction set

　　■Dual cycle instruction execution

　　■Performance: 6 MIPS @ 12MHz

　　■With 64-byte RAM and 9K internal ROM

　　■Support customized PID, VID by reading external EEPROM

　　■Support downstream port configuration by reading external EEPROM

　　■Multiple Transaction translator (MTT)

　　■MTT provides respective TT control logics for each downstream port.

　　■Each downstream port supports two-color status indicator, with automatic and manual modes compliant to USB specification Revision 2.0

　　■Built-in upstream port 1.5KΩ pull-up and downstream port 15KΩ pull-down resistors

　　■Support both individual and gang modes of power management and over-current detection for downstream ports

　　■Conform to bus power requirements of USB 2.0 specification

　　■Automatic switching between self-powered and bus-powered modes

　　■Integrate USB 2.0 transceiver

　　■Embedded PLL support external 12 MHz crystal / Oscillator clock input

　　■Optional 27/48 MHz Oscillator clock input (Only available in LQFP48 package)

　　■Support compound-device (non-removable in downstream ports) by I/O pin configuration (Only available in LQFP48 package)

　　■Number of Downstream port can be configured by GPIO without external EEPROM (Only available in LQFP48 package)

　　■Built-in 5V to 3.3V regulator

　　■Improve output drivers with slew-rate control for EMI reduction

　　■Internal power-fail detection for ESD recovery

　　■Available package types: 48 pin LQFP, 28 pin QFN and 28 pin SSOP
