The ISL12030 device is a low power real time clock with 50/60 AC input for timing synchronization, clock/calendar registers, single periodic or polled alarms. There are 128
bytes of user SRAM.
The oscillator uses a 50/60 cycle sine wave input. The real time clock tracks time with separate registers for hours, minutes, and seconds. The calendar registers contain the date, month, year, and day of the week. The calendar is accurate through year 2100, with automatic leap year correction and auto daylight savings correction.

Features
• 50/60 Cycle AC as a Primary Clock Input for RTC Timing
• Real Time Clock/Calendar
- Tracks Time in Hours, Minutes, Seconds and tenths of a Second

General Description
The MAX6648/MAX6692 are precise, two-channel digital temperature sensors. They accurately measure the temperature of their own die and a remote PN junction, and report the temperature in digital form using a 2-wire serial interface. The remote PN junction is typically the emitter-base junction of a common-collector PNP on a CPU, FPGA, or ASIC. The 2-wire serial interface accepts standard System Management Bus (SMBus)™ write byte, read byte, send byte, and receive byte commands to read the temperature data and to program the alarm thresholds. To enhance system reliability, the MAX6648/MAX6692 include an SMBus timeout. A fault queue prevents the ALERT and OVERT outputs from setting until a fault has been detected one, two, or three consecutive times (programmable). The MAX6648/MAX6692 provide two system alarms: ALERT and OVERT. ALERT asserts when any of four temperature conditions are violated: local overtemperature, remote overtemperature, local undertemperature, or remote undertemperature. OVERT asserts when the temperature rises above the value in either of the two OVERT limit registers. The OVERT output can be used to activate a cooling fan, or to trigger a system shutdown. Measurements can be done autonomously, with the conversion rate programmed by the user, or in a singleshot mode. The adjustable conversion rate allows the user to optimize supply current and temperature update rate to match system needs. Remote accuracy is ±0.8°C maximum error between +25°C and +125°C with no calibration needed. The MAX6648/MAX6692 operate from -55°C to +125°C, and measure temperatures between 0°C and +125°C. The MAX6648 is available in an 8-pin μMAX package, and the MAX6692 is available in 8-pin μMAX and SO packages.
