direction, and 0.5 in the horizontal and vertical directions.
3. Character pitch
4. Display start or end line (shutter function)

· ROM correction function
These flash memory products are manufactured and sold by SANYO Electric Co., Ltd. under license from
Silicon Storage Technologies, Inc. (SST).
The LC863 Series products are high functionality high-speed 8-bit CMOS single-chip microcontrollers that provide OSD functionality.
Since SANYO provides a full series of flash ROM versions instead of the earlier erasable EPROM and one-time programmable
PROM versions, this series can easily respond to needs for rapid specification changes during mass production ramp up and for
specification changes by target application. In addition to the large-capacity display RAM, the LC863 Series products provide a high-
performance OSD function that features increased CGROM capacity and supports simple graphics functions.
Since the LC8638XX, LC8632XX (DIP42, QFP48), LC863AXX, and LC8634XX (DIP36, SOP36) provide a built-in caption data
slicer circuit, they can implement, in a single chip, end products that provide caption, XDS (Extended Data Service), and Vchip
functions. Although the LC8633XX, LC8635XX, and LC863BXX do not include the built-in caption data slicer circuit, they are
essentially pin and function compatible with the LC8632XX, LC8634XX, and LC863AXX. This allows creation of a unified chassis
for NTSC and PAL format products.
Since these series products are available in not only a DIP package, but in a flat package as well, they can contribute to end product
chassis miniaturization.
