DESCRIPTION
The PT2221M and PT2222M are remote control transmitters utilizing CMOS technology specially designed for use on infrared remote control applications. They are pin-to-pin compatible with NEC μPD6121 and μPD6122 respectively. PT2221M is packaged in 20 pins SO and capable of controlling 32 functions and 3 double keys. PT2222M, on the other hand, is housed in 24 pins SOP and capable of controlling 64 function keys and 3 double keys. PT2221M/PT2222M may be paired with PT2225 to construct a powerful remote control system.
FEATURES
• CMOS technology
• Low power consumption (VDD=2.0 to 5.5V)
• Pin-to-Pin compatible with μPD6121/μPD6122
• Using SEL pin, PT2221M can support 64+6 function codes
• Using SEL pin, PT2222M can support 128+6 function codes
• Customer code can be selected (please contact PTC for details)
• Available in COB package
APPLICATIONS
• Audio equipment
• Television (TV)
• Cable TV tuner
• Video cassette recorder (VCR)
• Cassette deck
• Air conditioner
• Video compact disk (VCD)
• DVD ROM player
• Moniputer/Multi-media personal computer system
