ISL12082IB8Z - Renesas Electronics

Description: The ISL12082 device is a low power real time clock with timing and crystal compensation, clock/calendar, power fail indicator, 2 IRQs, periodic or polled alarm, timer/watchdog, and intelligent battery backup switching. The oscillator uses an external, low-cost 32. 768kHz crystal. The real time clock tracks time with separate registers for hours, minutes, seconds and hundredths of a second. The device has calendar registers for date, month, year and day of the week. The calendar is accurate through 2099, wit

ISL12082IB8Z Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the application note AN1443, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The ISL12082IB8Z has a built-in crystal oscillator startup timer that can be programmed to ensure the oscillator is stable before the RTC starts counting. The startup time can be adjusted by setting the XT1 and XT2 pins to the desired frequency and using the XT_TRIM register to fine-tune the oscillator frequency.
  • The ISL12082IB8Z is rated for operation from -40°C to +85°C, but it's recommended to operate within the -20°C to +70°C range for optimal performance and reliability.
  • The ISL12082IB8Z can be interfaced with a microcontroller using the I2C or SPI bus. The device has a dedicated I2C or SPI interface, and the communication protocol is described in the datasheet. The microcontroller can read and write data to the ISL12082IB8Z using the appropriate bus protocol.
  • The ISL12082IB8Z has a low-power mode that reduces power consumption to approximately 350 nA at 3.3V. This mode is useful for battery-powered applications where low power consumption is critical.
