DESCRIPTION
Equipped with low-voltage 1.8V operation, a carrier generation circuit for infrared remote control transmission, a standby release function through key entry, and a programmable timer, the µPD6133 and 6134 are suitable for infrared remote control transmitters.
For the µPD6133 and 6134, we have made available the one-time PROM product µPD61P34B for program
evaluation or small-quantity production.

FEATURES
• Program memory (ROM)
  · µPD6133: 512 ×10 bits
  · µPD6134: 1002 ×10 bits
• Data memory (RAM): 32 ×4 bits
• Built-in carrier generation circuit for infrared remote control
• 9-bit programmable timer : 1 channel
• Command execution time : 8 µs (when operating at fX= 1 MHz: ceramic oscillation)
• Stack level : 1 level (Stack RAM is for data memory RF as well.)
• I/O pins (KI/O) : 8 units
• Input pins (KI) : 4 units
• Sense input pin (S0) : 1 unit
• S1/LED pin (I/O) : 1 unit (When in output mode, this is the remore control transmission display pin.)
• Power supply voltage : VDD= 1.8 to 3.6 V (when operating at fX= 500 kHz)
                                 VDD= 2.2 to 3.6 V (when operating at fX= 1 MHz)
• Operating ambient temperature : TA= –40 to +85 ˚C
• Oscillation frequency : fX= 300 kHz to 1 MHz
• POC circuit (Mask option)

APPLICATION
Infrared remote control transmitter (for AV and household electric appliances)
