RTCs are 73% smaller, 45% thinner than competition

Suited for battery-powered portable applications such as remote utility meters, copy/fax/scanner/printers, and digital photo albums, the ISL12057, ISL12058, and ISL12059 real-time clocks/calendars operate from 1.4 to 3.6 V. Measuring 2 x 2 mm and only 0.55 mm thick, the ISL12057 and ISL12058 are claimed by the company to be the industry’s smallest and thinnest offering a 73% reduction in board space and 45% thinner than the competition.

Each real-time clock/calendar uses an external 32.768-kHz crystal that tracks time by date, year, months, week, and hour, minute, and seconds. Multiple selectable alarms allow a flexibility of alarm choices, with outputs for beepers or lights. The calendar is accurate through 2099, with automatic leap-year correction.

All parts offer a two-wire I2 C interface. The ISL12059 provides a 512-Hz frequency output, while the ISL12057/8 offer four selectable frequency outputs. The ISL12059 is offered in an 8-lead SOIC package, and the ISL12057/8 in 8-lead µTDFN, MSOP, and SOIC. The ISL12058 is also offered in an 8-lead TDFN. (From $0.92 ea/1,000 — available now.)
