UPD6124A
Overview
The µPD6124A and 6600A are 4-bit single-chip microcontrollers for infrared remote controllers for TVs, VCRs, stereos, cassette decks, air conditions, 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: 17.6 µs (with 455-kHz ceramic resonator) Program memory (ROM) capacity
- µPD6124A: 1002 × 10 bits
- µPD6600A: 512 × 10 bits * * * * *
- 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) Low-voltage operation * * * *
- Data memory (RAM) capacity: 32 × 5 bits 9-bit programmable timer: 1 channel I/O pins (KI/O): 8 pins Input pins (KI): 4 pins Serial input pins (S-IN): 1 pin Caution µPD6124A: VDD = 2.2 to 5.5 V µPD6600A: VDD = 2.2 to 3.6 V To use the NEC transmission format, ask NEC to supply the custom code. Do not use R0 when using a register as an operand of the branch instruction. The information in this document is subject to change without notice.
