GL603USB/GL603USB-A/GL603USB-B

Revision 1.4

FEATURES

• 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 400µA for whole mouse system (mask type)

• 8-bits free-running timer
