UPD6125ACA中文资料4-BIT SINGLE CHIP MICROCONTROLLER FOR REMOTE CONTROL TRANSMISSION数据手册Renesas规格书

描述 Description

DESCRIPTION
The µPD6125A and 6126A are 4-bit single-chip microcontrollers for infrared remote controllers for TVs, VCRs, stereos, cassette decks, air conditioners, etc.
These microcontrollers consist of ROM, RAM, a 4-bit parallel-processing ALU, a programmable timer, key input/output ports, and transmit output ports. Functioning is controlled in software.FEATURES
• Transmitter for programmable infrared remote controller
• 19 types of instructions
• Instruction execution time: 17.6 µs (with 455-kHz ceramic oscillator)
• Program memory (ROM) capacity: 1002 × 10 bits
• Data memory (RAM) capacity: 32 × 5 bits
• 9-bit programmable timer: 1 channel
• I/O pins (KI/O): 8 pins
• I/O pins (I/O)
  
• µPD6125A: 4 pins
  
• µPD6126A: 8 pins
• Input pins (KI): 4 pins
• Serial input pins (S-IN): 1 pin
• Transmission-in-progress indication pin (S-OUT): 1 pin
• Transmit carrier frequency (REM) fOSC/12, fOSC/8
• Standby operation (HALT/STOP mode)
• Low power consumption
• Current consumption in STOP mode (TA = 25°C) 1 µA MAX.
• Low-voltage operation: VDD = 2.0 to 6.0 V
