    64 KEYS ENCODER
GENERAL DESCRIPTION
FEATURE
The SM5025A/B is an infrared remote control
encoder LSI utilizing CMOS technology.
The transmission code consists of "leader
pulse", "16 bit customer code", and "16 bit
data code". Using Micro-processors for
decoder,various applications can be realized.
APPLICATIONS
* Low voltage operation ......VDD = 2.0 to 3.3V
* Low power consumtpion ..... IDD < 1
A at
standby mode
