ISL12021規(guī)格書詳情
Low Power RTC with VDD Battery Backed SRAM and Embedded Temp Compensation ±5ppm with Auto Day Light Saving
The ISL12021 device is a low power real time clock with an embedded Temp sensor for oscillator compensation, clock/calendar, power fail, low battery monitor, brown out indicator, single periodic or polled alarms, intelligent battery backup switching and 128 bytes of battery-backed user SRAM.
The oscillator uses an external, low-cost 32.768kHz crystal.
The real time clock tracks time with separate registers for hours, minutes, and seconds. The device has calendar registers for date, month, year and day of the week. The calendar is accurate through 2099, with automatic leap year correction.
Daylight Savings time adjustment is done automatically, using parameters entered by the user. Power fail and battery monitors offer user-selectable trip levels. A time stamp function records the time and date of switchover from VDD to battery power, and also from battery to VDD power.
