Pin Description
Pin No.
Pin Name
I/O
Description
1,2
Z1, Z2
I
Z axis input : Supports two kinds of scroller input,
optomechanical and mechanical
3
RESET
I
Reset input : Resets internal circuit by input low, normal is con-
nected to high by internal pull-high resistor (120k ).
4
MODE
I
MS or PS/2 mode selection : Low for PS/2 mouse, high for MS
mouse. The MS PnP mouse ID code sure will appear when this pin
rise from low to high. Normal is connected to low by internal
pull-lowresistor(60k ).Themodeinputtransitionvoltageis2.0V.
5
OSCI
I
Oscillator in : Connect to 2MHz crystal or resonator
6
OSCO
O
Oscillator out : Connect to 2MHz crystal or resonator
7
CLOCK
I/O
CLOCK I/O : PS/2 mouse CLOCK line. NMOS open drain output
with 7.5k
pull-high resistor.
8
DATA
I/O
DATA/RXDI/O PS/2mouseDATAlineorMSmouseRXDoutput.
NMOS open drain output with 7.5k
pull-high resistor.
9
VSS
Negative power supply, ground
10~12
RB, RO, LB
I
Right Button : Normal pull-high (45k ), press connect to low.
Rolling Button : Normal pull-high (45k ), press connect to low.
Left Button : Normal pull-high (45k ), press connect to low.
13~16
X1, X2,
Y1, Y2
I
X/Y axis input : Auto level detecting input. Any signal over 0.6V
V
PP
is acceptable but the +V
P
cannot be over 2.5V
17
TEST
I
IC test pin : with built-in pull-low resistor. In normal operation
this is connected to VSS or floating. While the pin is connected to
VDD, this will provide the H/W test. The chip will accord the state
of the RB pin, to switch the X1/Y1 and X2/Y2 via the PIN RO and
LB output.
