ISL12058IBZ-T - Renesas Electronics

Description: The ISL12058 device is a low power real time clock with clock/calendar, and alarm function. 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.
