UPD6126A
Overview
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.
- Transmitter for programmable infrared remote controller 19 types of instructions Instruction execution time: ceramic oscillator) 17.6 µs (with 455-kHz
- 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 * * * * * * * * * *
- 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 Caution To use the NEC transmission format, ask NEC to supply the custom code. The mask option (PLA data) setting of µPD6125A, µPD6126A is different from that of the µPD6125,
- When a register is used as the operand of a branch instruction, do not use R0. The information in this document is subject to change without notice.
