Specifications

Caution: Even if one of the parameters exceeds its absolute maximum rating even momentarily, the quality of the product may be degraded. The absolute maximum rating therefore specifies the upper or lower
limit of the value at which the product can be used without physical damages. Be sure to use the product(s) within the ratings.

Description

   The PD6124A 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 PD6124, 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 PD6124A or 6600A, and for small-scale production of such systems.
