描述 Description

DESCRIPTION
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. Functioning is controlled by a program. A one-time PROM, model μPD61P24, to which a program can be written only once is also available. This one-time PROM is ideal for evaluation of programs running in a μPD6124A or 6600A, and for small-scale production of such systems.FEATURES
? 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
? 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
? Transmission-in-progress indication pin (S-OUT): 1pin
? 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
μPD6124A: VDD = 2.2 to 5.5 V
μPD6600A: VDD = 2.2 to 3.6 V
