UPD64A中文资料4-BIT SINGLE-CHIP MICROCONTROLLERS FOR INFRARED REMOTE CONTROL TRANSMISSION数据手册Renesas规格书

描述 Description

DESCRIPTION
The µPD64A and 65 feature low-voltage 2.0 V operation, and incorporate a carrier generator for infrared remote control transmission, a standby release function through key entry, and a programmable timer, making them ideal for infrared remote control transmitters. A one-time PROM product, the µPD6P5 is also available for program evaluation or small-quantity production.FEATURES
• Program memory (ROM)
• µPD64A: 1002 × 10 bits
• µPD65: 2026 × 10 bits
• Data memory (RAM): 32 × 4 bits
• On-chip carrier generator for infrared remote control
• 9-bit programmable timer: 1 channel
• Instruction execution time: 16 µs (when operating at fX = 4 MHz: ceramic oscillation)
• Stack levels: 1 (stack RAM is also used for data memory RF)
• I/O pins (KI/O): 8
• Input pins (KI): 4
• Sense input pin (S0, S2): 2
• S1/LED pin (I/O): 1 (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
• Oscillation frequency: fX = 2.4 to 8 MHz
• On-chip POC circuitAPPLICATIONS
Infrared remote control transmitters (for AV and household electric appliances)
