M35070-XXXSP/FP
SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DESCRIPTION
The M35070-XXXSP/FP is a character pattern display control IC can
display on the CRT display the liquid crystal display and the plasma
display. It can display 2 pages (24 characters × 12 lines per 1 page)
at the same time. It uses a silicon gate CMOS process and it housed
in a 20-pin shrink DIP package (M35070-XXXSP) or a 20-pin shrink
SOP package (M35070-XXXFP).
For M35070-002SP/FP that is a standard ROM version of M35070-
XXXSP/FP respectively, the character pattern is also mentioned.
