DS1202S Serial Timekeeping Chip For Simple RTC Needs

DS1202S is used in embedded products that need basic real-time clock/calendar functions without adding a full I2C or SPI subsystem. It communicates through a simple serial interface and supports time and date tracking for timestamps, service logs, and user-facing clocks. DS1202S also includes a small on-chip RAM area, which is helpful for retained flags and small settings that can travel with the timekeeper. The RAM size is 24 bytes, and the register set covers standard clock fields such as seconds, minutes, and hours, plus date information. DS1202S is a practical part for repairs and maintenance of older control boards where the interface and footprint are already fixed. If you’re keeping legacy hardware in service, DS1202S helps preserve time and small retained data with minimal changes. Request a quote for DS1202S.
