DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD4701A  
INCREMENTAL ENCODER COUNTER  
DESCRIPTION  
The µPD4701A is a counter for an X, Y 2-axis incremental encoder. When a two-phase encoder signal is input  
for the X and Y axes, direction discrimination and computation is performed, and count data is output in 8-bit parallel  
form. In addition, a 3-contact-point input buffer is incorporated, which is useful for applications which use a pointing  
device such as a mouse or track-ball. The CPU checks the switch input flag or count flag and reads the 12-bit count  
data in two operations, one for the lower byte and one for the upper byte. The key input flag is output together with  
the count data in the upper byte.
