GPIO ICs Series  
Key Encoder IC  
BU1851GUW  
No.09098EAT03  
Description  
Key Encoder IC can monitor up to 8x8 matrix (64 keys), which means to be adaptable to Qwerty keyboard. We apt the  
architecture that the information of the only key which status is changed, like push or release, is encodehe 8 bits  
data. This can greatly reduce the CPU load which tends to become heavier as the number of keys cre
(Previously, all key's status is stored in the registers.)  
Furthermore, auto sleep function contribute to low power consumption, when no keys are pressed. It is lso equipped with  
the various functions such as ghost key rejection, N-key Rollover, Built-in power on reset anscillator.  
Features  
1) Monitor up to 64-matrix keys  
2) Under 5A Stand-by Current  
3) Built-in Power On Reset  
4) Ghost key rejection
