Real Time Clock, 4 wire serial, TSSOP-10G, T&R (2KU)
The R2043x is a CMOS real-time clock IC connected to the CPU by four signal lines, CE, SCLK, SI, SO, and configured to perform serial transmission of time and calendar data to the CPU. The periodic interrupt circuit is configured to generate interrupt signals with six selectable interrupts ranging from 0.5 seconds to 1 month. The 2 alarm interrupt circuits generate interrupt signals at preset times.
Since the package for these ICs are TSSOP10G (4.0×2.9×1.0: R2043T) or QFN023023-16 (2.3×2.3×0.4:R2043L), high density mounting of ICs on boards is possible.
