Specifications

Maximum ratings are the extreme limits to which the GL652USB can be exposed without permanently damaging it. The GL652USB contains circuitry to protect the inputs against damage from high static voltages; however, do not apply voltages higher than those shown in the table. Keep VIN and VOUT within the range GND (VIN or V OUT) VCC. Connect unused inputs to the appropriate voltage level, either GND or VDD.

Description

The GL602USB is an 8-bit RISC-like high performance microcontroller with a built-in 1.5Mbps SIE and transceiver. The microcontroller features 33 instructions optimized for USB keyboard. There are 96 bytes onchip RAM and 4K x 14 bits program ROM incorporated into the micro-controller. The micro-controller GL602USB features 18 output pins and 8 input pins to make a 18 x 8 key matrix. Additionally, 3 GPIO pins are strong enough to drive LEDs. 4 GPIO pins can be used by any function, for example, support a PS/2 3D mouse to USB 3D mouse onverter in the default firmware. Legacy USB cable of GL602USB can be used for keyboard in USB mode. All GPIO ports feature low EMI emissions as a result of improved output drivers with slew-rate control.
