Single Chip 4-Bit Microcontroller for Small-Scale Control-Oriented Applications
The L, LC6528N belong to our single-chip 4-bit microcontroller LC6500 series fabicated using CMOS process technology and are suited for use in small-scale control-oriented applications. Their basic asrchitecture and instruction set are the same. Application areas include the standard logic circuits and applications where the number of controls is small. The L, LC6528N have relation to the / H. The C version can be replaced by N version, and the H version (a part of the function is different). The L version is added as a low voltage version. The following show the careful difference of C and N version when you replace C version with N version. C version N version Operating Temperature 1-pin C oscillation exist not exist 400kHz MURATA R=2.2k 800kHz MURATA R=0 R=2.2k KYOCERA R=0 1MHz MURATA R=0 R=2.2k (Note) The suffix of recommend oscillation is changed C version and N version, but the characteristic is no change.Features
