MOS INTEGRATED CIRCUIT
µPD6124A, 6600A
4-BIT SINGLE-CHIP MICROCONTROLLER
FOR REMOTE CONTROL TRANSMISSION
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.

Caution 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.
