ISL12026AIBZ - 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

ISL12026AIBZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a ferrite bead or a 10uF capacitor to filter the power supply.
  • Use a high-quality crystal oscillator with a frequency tolerance of ±20 ppm or better. Also, ensure that the crystal is properly matched to the internal oscillator circuitry, and that the PCB layout is optimized for minimal noise and interference.
  • The ISL12026AIBZ is rated for operation from -40°C to +85°C. However, the device may still function outside this range, but with reduced accuracy and reliability.
  • Yes, the ISL12026AIBZ has a built-in battery-backed clock (BBR) pin that allows connection to a battery or supercapacitor. This enables the device to maintain timekeeping during power failures or battery replacement.
  • The POR and BOR functions are enabled by default. To disable them, tie the POR and BOR pins to VCC. However, it is recommended to keep them enabled to ensure proper device operation and prevent unexpected behavior.
