Technical Data
The LC6512A, 6513A are members of our LC6500 series of CMOS microcomputers. For their internal functions, refer to
the LC6500 SERIES USFR
′
S MANUAL. Those which differ from the description in the USER
′
S MANUAL are de-
scribed in this catalog. Carefully study features and Appendix 4 Standby Function in this catalog before using the LC6512A,
6513A.
(Note) Nothing must be connected to NC
pins internally or externally.
When mounting the QIP version on the
board, do not dip it in solder.
