DESCRIPTION
S3C1850, a 4-bit single-chip CMOS microcontroller, consists of the reliable SMCS-51 CPU core with on-chip
ROM and RAM. Eight input pins and 11 output pins provide the flexibility for various I/O requirements. Auto reset
circuit generates reset pulse every certain period, and every halt mode termination time. The S3C1850
microcontroller has been designed for use in small system control applications that require a low-power, cost -
sensitive design solution. In addition, the S3C1850 has been optimized for remote control transmitter and has
built-in Transistor for I.R.LED drive.
