The BM8563EMA with Real-time Clocks MSOP-8 RoHS is an integrated circuit (IC) from GATEMODE Electronics. It is an ultra-low power, inexpensive real-time clock (RTC) that helps keep track of the current time in a digital system. The BM8563EMA is contained in an 8-pin MSOP package, making it ideal for space constrained designs. It supports a wide temperature range (-10°C to +65°C) and an ultra-low power consumption (0.45uA @ 2V). It has a built-in oscillator, and the accuracy of its timekeeping is 10 ppm, which is more than enough for most applications. It also has a variety of features, including an alarm, a battery backup option, and various count and control operations. With its great performance and low cost, GATEMODE's BM8563EMA is an excellent option for applications needing a simple, accurate real-time clock.
