UPD63A General Description


Equipped with low-voltage 1.8 V operation, a carrier generation circuit for infrared remote control transmission, a standby release function through key entry, and a programmable timer, the mPD63, 63A, and 64 are suitable for infrared remote control transmitters.

For the mPD63, 63A and 64, we have made available the one-time PROM product mPD6P4B for program evaluation or small-quantity production.

UPD63A Features

•Program memory (ROM) mPD63 : 512 ´ 10 bits mPD63A: 768 ´ 10 bits mPD64 : 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 ms (when operating at fX = 8 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 remote control transmission display pin.)
• Power supply voltage : VDD = 1.8 to 3.6 V (when operating at fX = 4 MHz) VDD = 2.2 to 3.6 V (when operating at fX = 8 MHz)
•Operating ambient temperature : TA = 40 to +85
•Oscillator frequency : fX = 2.4 to 8 MHz
•POC circuit (Mask option)
