4-BIT SINGLE-CHIP MICROCONTROLLER FOR INFRARED REMOTE CONTROL TRANSMISSION

NEC => Renesas Technology 

DATA SHEET

MOS INTEGRATED CIRCUIT

µPD62A

4-BIT SINGLE-CHIP MICROCONTROLLER

FOR INFRARED REMOTE CONTROL TRANSMISSION

DESCRIPTION

Due to its low-voltage 2.0 V operation, on-chip carrier generator for infrared remote control transmission, standby

release function through key entry, and programmable timer, the µPD62A is ideal for infrared remote control

transmitters.

For the µPD62A, the one-time PROM product µPD6P4B has been made available for program evaluation or

small-scale production.

FEATURES

• Program memory (ROM): 512 × 10 bits

• Data memory (RAM): 32 × 4 bits

• On-chip carrier generator for infrared remote control

• 9-bit programmable timer:

1 channel

• Command execution time:

8 µs (when operating at fX = 8 MHz: ceramic oscillation)

• Stack levels:

1 (Stack RAM is also available for data memory RF.)

• I/O pins (KI/O):

8

• Input pins (KI):

4

• Sense input pin (S0)

• S1/LED pin (I/O): When in output mode, this is the remote control transmission display pin.

• Power supply voltage:

VDD = 2.0 to 3.6 V

• Operating ambient temperature: TA = –40 to +85˚C

• Oscillator frequency:

fX = 2.4 to 8 MHz

• POC (Power On Clear) circuit (Mask option)

APPLICATION

Infrared remote control transmitter (for AV and household electrical appliances)
