LC863864B Datasheet, PDF (2/20 Pages) Sanyo Semicon Device – 8-bit 1-chip Microcontroller

LC863864B/56B/48B/40B/32B/28B/24B/20B/16B
Continued from preceding page.
• ROM correction function
• 16-source 10-vectored interrupt system
• Integrated system clock generator and display clock generator
Only one X’tal oscillator (32.768kHz) for PLL reference is used for both generators
TV control and the closed caption function
All of the above functions are fabricated on a single chip.

40960 × 8-bits / 32768 × 8-bits / 28672 × 8-bits /
24576 × 8-bits / 20480 × 8-bits / 16384 × 8-bits for program
16128 × 8-bits for CGROM
„Random access memory (RAM) : 768 × 8-bits (including 128 bytes for ROM correction function)
352 × 9-bits (for CRT display)
„OSD functions
• Screen display : 36 characters × 16 lines (by software)
• RAM
: 352 words (9-bits per word)
Display area : 36 words × 8 lines
Control area : 8 words × 8 lines
• Characters
Up to 252 kinds of 16 × 32 dot character fonts (4 characters including 1 test character are not programmable)
