|
| |
| '''GENERAL DESCRIPTION'''
| |
|
| |
| The TLCS-47 is the high speed and high performance, 4-bit single chip microcomputer series designed for general purpose use.
| |
|
| |
| The TLCS-47 has variously powerful functions in order to meet with the advanced and complicated applications. In addition, software compatible NMOS family (TLCS-47N) and CMOS family (TLCS-47C) are also provided.
| |
|
| |
|
| |
| '''FEATURES'''
