Revision 1.3

FEATURES

• Low-cost solution forlow-speed USB mouse

• 8-bit micro-controller

− Operation Speed: DC to 6MHz clock input

− Performance: 3 MIPS @ 6MHz

− 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(GL600USB)/11(GL600USB-A)/9(GL600USB-B) general purpose I/O pins (OTP type is

less a GPIO pin than mask type)

− Internal RC clock to wakeup periodically (about 500ms) when suspend

− Up to 8(GL600USB)/6(GL600USB-A)/4(GL600USB-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)

• Internal memory

− 64 bytes of RAM (special purpose register is not included)

− 1.75K x 14 of program ROM

• Integrated USB transceiver

• 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

• 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

• Available in cost saving 20-pin(GL600USB) PDIP, 18-pin(GL600USB-A) PDIP and 16-

pin(GL600USB-B) PDIP
