The mPD17203A and 17204 are 4-bit single-chip microcontrollers for infrared ray remote control transmitters that
integrate an internal high-capacity static RAM (XRAM), three-channel timer, remote controller carrier generator, amplifier
for the signals received from the remote controller, and wave shaping circuit on a single chip.
These microcontrollers employ the 17K architecture, which uses general-purpose registers. They perform data
transfer and direct operations between data memory areas instead of indirect operations which hitherto have been
performed through accumulators. Furthermore, all the instructions consist of 16 bits per word, assuring highly efficient
programming.
The mPD17P203A and 17P204, one-time PROM versions to which data can be written only once, are also available.
These PROM versions are helpful for program evaluation for the mPD17203A and 17204, and suitable for small-scale
production.
