The LC8632/LC8634/LC8638/LC863A Series are closed caption TV control 8-bit microcontrollers that integrate an extensive set of
peripheral functions around a CPU core that operates with a minimum cycle time of 0.424 µs. The peripheral functions include 16 to
64 KB of program ROM, 16 KB of CGROM, 384 to 640 bytes of RAM, 352 9 bits of CRT display RAM, as well as 16-bit timer/
counter, PWM, A/D converter, I2C bus compatible serial interface, closed caption data slicer, and closed caption OSD circuits.
These microcontrollers can implement TV control and closed caption display in a single chip.
