ISL120x Real Time Clock USB Evaluation System
This evaluation system is a hardware and software platform for testing Renesas real-time clock (RTC) devices; the system requires only a PC for the controller and power...
Overview
Description
The ISL12057 device is a low-power, real-time clock that is pin compatible and functionally equivalent to Maxim DS1337 with clock/calendar and alarm function. The oscillator uses an external, low-cost 32. 768kHz crystal with 6pF load capacitance. 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.
