ISL12026IVZ - Renesas Electronics

Description: The ISL12026 and the ISL12026A devices are micro power real time clocks with timing and crystal compensation, clock/calender, power-fail indicator, two periodic or polled alarms, intelligent battery backup switching, and integrated 512x8-bit EEPROM configured in 16 Bytes per page. 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. Th

ISL12026IVZ 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 ISL12026IVZ can be configured for use with a specific oscillator crystal by selecting the appropriate values for the load capacitors (CL1 and CL2) and the feedback resistor (RFB). Renesas provides a crystal selection guide in the application note AN1444, which includes a calculator to determine the optimal values for these components.
  • The ISL12026IVZ has an operating temperature range of -40°C to +85°C, but it can be extended to -55°C to +125°C with proper derating. Refer to the datasheet for more information on temperature derating.
  • Renesas provides a troubleshooting guide in the application note AN1445, which includes steps to identify and resolve common issues with the ISL12026IVZ, such as oscillation or frequency instability. The guide also includes tips for debugging and optimizing the device's performance.
  • Yes, the ISL12026IVZ can be used in a redundant clock system. The device has a clock switchover feature that allows it to automatically switch to a backup clock source in the event of a failure. Renesas provides more information on implementing redundant clock systems in the application note AN1446.
