It communicates over an I²C 2-wire serial bus, making it a drop-in for any microcontroller with an I²C peripheral. Timekeeping current is only 0.6 µA to 0.7 µA at 3 V to 5 V, so the RTC adds negligible drain to a battery-backed supply rail. Housed in an 8-lead TSSOP/MSOP package (0.118-inch, 3.00 mm width), the supplier device package is 8-uMAX/uSOP. The small footprint keeps the PCB area under 15 mm², and the 0.65 mm pin pitch is routable on a two-layer board with standard design rules. The part is supplied in a Tube, so for volume pick-and-place, confirm the reeled variant if your line requires tape-and-reel feed.","metaTitle":"Analog Devices DS1342U+ RTC, I²C, 8-uMAX, -40 to 85°C","metaDescription":"DS1342U+ real-time clock from Analog Devices, I²C interface, 1.8-5.5V supply, 0.6µA timekeeping, -40 to 85°C, 8-uMAX.
