GL603USB-B

·  Low-cost solution for PS/2 and low-speed USB combo mouse
·  8-bit micro-controller
-  Operation Speed: DC to 6MHz clock input
-  Performance: 3 MIPS/6 MIPS @ 6MHz (6 MIPS is only for mask type)
-  Single cycle instruction execution
-  RISC-like architecture
-  USB optimized instruction set
·  USB Specification Compliance
-  Conforms to USB 1.5Mbps Specification, Version 1.1
-  Conforms to USB HID Class Specification, Version 1.1
-  Supports 1 device address and 2 endpoints (include endpoint 0)
·  I/O ports
-  Up to 13(GL603USB)/11(GL603USB-A)/9(GL603USB-B) general purpose I/O pins (OTP type is less a GPIO pin than mask type, and the number is not included CLK/DATA in PS/2 mode).
-  Internal RC clock to wakeup periodically (about 200ms for mask type, 500ms for OTP type) when suspend
-  Up to 8(GL603USB)/6(GL603USB-A)/4(GL603USB-B) special purpose I/O pins optimized for photo-sensor (Internal build in 4 bits ADC)
-  Up to 2 I/O pins with large current drive capability to drive LED (Sink current up to 16 mA)
-  2 open drain I/O pins combined with USB D+/D- functions to be used as DATA and CLK in PS/2 mode
·  Internal memory
-  64 bytes of RAM (special purpose register is not included)
-  2.75K x 14 of program ROM
·  Integrated USB transceiver with open drain I/O capability
-  In PS/2 mode, D+ used as CLK and D- used as DATA
-  Use legacy USB cable and add an USB to PS/2 converter to connect PS/2 port
·  Patented full-range detection for photo-sensor
-  Removes the expensive process of matching LED and photo-sensor
·  On-chip 3.3v output
-  No external regulator required
·  Improved output drivers with slew-rate control to reduce EMI
·  6 MHz external clock
·  Build in clock generator to generate 12 MHz internal clock for micro-controller (mask type only)
-  Improve photo-sensor sampling rate up to 100 us per sample in USB mode and 80 us in PS/2 mode
·  Internal power-on reset(POR)
·  Internal power-fail detector
·  Supports suspend/normal mode power management
-  Suspend current lower than 400mA for whole mouse system (mask type)
·  8-bits free-running timer
