M35062-XXXSP
SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DESCRIPTION
M35062-XXXSP is CATV screen display control IC which can display
40 (horizontal) × 17 (vertical). It has built-in SYRAM which can be
used with character ROM.
It uses a silicon gate CMOS process and M35062-XXXSP housed in
a small 32-pin shrink DIP package. For M35062-001SP that is a stan-
dard ROM version of M35062-XXXSP, the character pattern is also
mentioned.
