MX83063H
USB+PS/2 Keyboard Encoder
1.INTRODUCTION
The MX83063H is a single chip keyboard encoder, these devices detect the key press and release
activity, sends the scan code to system, and accepts the command from system. The MX83063H
function both in USB and PS/2 interface environment. For PS/2 interface, it supports IBM PC AT and all
compatible machines. For USB interface, it supports the USB standard request version 1.1 as well as
HID class request version 1.1.
The MX83063H is the most powerful USB+PS2 keyboard encoder. It is a crystal-less and low cost
BOM solution with the minimal external components.

microseconds. If the system lowers the clock lines before the leading edge of the 10th clock, the
keyboard should stop sending, then buffers the data and return the clock and data lines to a high
state.
5.1.5 KEYBOARD DATA INPUT
When the system is ready to send data to the keyboard, it first checks the clock line to see if
keyboard is sending data. If keyboard is not sending data or it is sending data but has not reached
the 10th clock, the system can inhibit the interface by forcing the clock line low for more than 60
microseconds and prepares to send data. The keyboard checks the clock line status at least every
5 milliseconds. If a system Request to Send (RTS) is detected, the keyboard clocks 11 bits in.
After the 10th bit, the keyboard checks for a high state in the data line then pulls it low and clocks
one more bit to signal the system that data has been received. If data is low after the 10th bit, it
indicates a frame error. The keyboard should continue to count until the data line goes high, then
pulls it low and issues a RESEND to the system.
5.1.6 COMMAND FROM THE SYSTEM
The system can send commands to the keyboard at any time. The keyboard needs to respond
within 20 milliseconds, unless the system prevents keyboard output, when doing self test or
executing a reset. The following are the keyboard input commands and the actions that the
keyboard needs to take.
Set /Reset Status indicators (Hex ED)
-Responds with ACK –Receives option byte –Responds with ACK –Updates status indicators
–Returns to previous scanning state
Echo (Hex EEH)
-Responds with EE hex –Returns to previous scanning state
Invalid commands (Hex EF and F1)
-Returns a RESEND command –Returns to previous scanning state
Select Alternate Scan Codes (Hex F0)
-Responds ACK –Clears output buffer –Sets the default Typematic rate/delay –Clears last
Typematic key –Receives option byte –Responds ACK –Option byte : 01 : selects scan code Set 1
