SC8521規(guī)格書(shū)詳情
DESCRIPTION
The SC8521 can be used in infrared remote control transmitters. It generates output pulses, in accordance with the RC5 protocol, when a key is pressed. The IC does not contain a software programmable processor. However, it does contain a ROM in which the codes that have to be transmitted are stored. The oscillator frequency may be optionally chosen as 432KHz. For 432KHz additional external capacitors must be connected. When a key in the key-matrix is pressed a driveline will be connected to a sense line. This causes the oscillator to start and a corresponding code will be generated conforming to the RC5 protocol.
FEATURES
? RC5 protocol
? Maximum of 56 keys (20-pin version)
? Option of multi-system or single system transmitter
-- Multi-system: maximum 8 system, selection by key
-- Single system: maximum 8 different systems per IC, selection by jumper wire or switch.
? Power-down and key wake-up
? High output current (≤45mA)
? Oscillator frequency of 432KHz
? Multiple key protection
? Option of 25 or 33 duty factor
