The LC864000 Series are high-speed, advanced-func- tion CMOS 8-bit single-chip microcontrollers with an on-chip caption display function. When combined with a data slice front-end lC (LA7945), the previous products - the LC8640XX - could be used for TV sets with built-in closed- caption functions. In contrast to this, the newly developed LC8641XX has an on-chip data slice function that extracts caption data, making it possible to build TV sets with built-in closed captioning with just this single chip. What is more, OSD with an advanced-function version of the display RAM for full-screen support so well received in the LC8640XX is also on-chip, enabling support for EDS (Extended Data Service) as well. EPROM with window versions and one- time PROM versions have been incorporated into the series, allowing development time for the application system to be greatly reduced. The LC8641XX integrates many poweriul functions on a single chip. Centered around a CPU core that performs 8- bit processing in l ys, the microcontroller includes 12K to 64K bytes of ROM, 256 0r 384 bytes of RAM, and an OSD function for captions with 640 x 9bits of full-screen display RAM and character-generator ROM which generates 256 types of characters. Also included are a 16-bit timer/ counter, a multiple-use PWM 16-bit timer, a 10-channel x 7- bit PWM, a 4-channel x 4-bit AJD converter, 8-bit synchro- nized serial l/0 channels, a watchdog timer, a remote con- trol signal receive circuit, l/0 ports, numerous interrupts (12 sources and 10 vectors), and a standby function.
