DESCRIPTION OF THE S3C1840/C1850/C1860 MCUS
The S3C1840/C1850/C1860 4-bit single-chip CMOS microcontroller is designed using the reliable SMCS-51 CPU
core with on-chip ROM and RAM. An auto-reset circuit generates a
RESET pulse in regular intervals, and can be
used to initiate a Halt mode release. The S3C1840/C1850/C1860 microcontroller is intended for use in small
system control applications that require a low-power and cost-sensitive design solution. In addition, the
S3C1840/C1850/C1860 has been optimized for remote control transmitters.
