三合微科股份有限公司 SM5025A/B
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
* 64 function keys and 3 double action keys
* 128 + 6 function codes are available.
(Using SEL terminal)
* 65536 customer codes can be selected.
(Using external R, Diode-SM5025A or
internal MASK ROM-SM5025IRB)
* 24pin SOP or DIP
1. Audio Remote Control
2. Video Remote Control
3. Consumer Product Remote Control
