STMicroelectronics has announced three new serial realtime clocks (RTCs) for use in a broad range of applications. All are available in a lead-free 16-pin QFN package, 3 mm square.
The new devices - the M41T50, M41T60 and M41T62-65 - provide date and time information, from seconds to centuries, over an I²C serial bus. All have automatic leap year compensation. They are designed for a bus operating voltage from 3,6 V down to 1,3 V, but will maintain timekeeping at supply levels as low as 1,0 V. Operating current is just 350 μA on a 3,0 V supply. Standby currents will be less than 650 nA at 3,0 μV.
The small size and low power requirement of these RTC chips means that they are good choices for portable and handheld products where space and power are at a premium, while the variety of features means they also suit medical and industrial systems as well as white goods.
Each clock chip offers a mix of operational features for different types of applications. The M41T60 and M41T62/63/64/65 series each have built-in 32,768 kHz oscillators, used with external crystals, and each includes an 'oscillator stop detection' feature to warn if the recorded time might be corrupted. With software clock calibration they have an accuracy of better than 2 ppm at
25°C.
The M41T60 provides crystal controlled time-of-day clock and calendar, while the M41T62/63/64/65 series adds a watchdog timer and various combinations of alarm interrupt, 32 kHz output, programmable square wave output, and watchdog output. The M41T50 operates from either a 50 Hz or a 60 Hz input which can be derived from line power. In addition to the time-of-day clock and calendar, user functions include a programmable alarm interrupt, and a 1 Hz square wave output which minimises the need for external circuitry.
