ISL1208IRT8Z-TK - Renesas Electronics

Description: The ISL1208 device is a low power real time clock with timing and crystal compensation, clock/calendar, power fail indicator, periodic or polled alarm, intelligent battery backup switching and battery-backed user SRAM. 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. The calendar is accurate through 2099, with automatic leap year c

ISL1208IRT8Z-TK 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 ISL1208 has a built-in crystal oscillator startup timer that can be programmed to ensure the oscillator is stable before the device starts operating. The startup time can be adjusted using the XT1 and XT2 pins, and the recommended values are provided in the datasheet.
  • The ISL1208 is rated for operation from -40°C to +85°C, but it's essential to consider the specific application and environmental conditions to ensure reliable operation. Renesas provides thermal management guidelines in the datasheet and application notes.
  • The ISL1208 has several power-saving features, including a low-power mode and a shutdown mode. These can be configured using the control registers and pins. Renesas provides detailed information on power management in the datasheet and application notes.
  • Renesas recommends using a 10uF ceramic capacitor and a 1uF ceramic capacitor in parallel, placed close to the VDD pin, to ensure stable power supply and minimize noise.
