1337AGDVGI - Renesas Electronics

Description: The 1337AG device is a low power serial real-time clock (RTC) device with two programmable time-of-day alarms and a programmable square-wave output. Address and data are transferred serially through an I2C bus. The device provides seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator.

1337AGDVGI Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (R01AN3601EU0100) which includes thermal design considerations, such as thermal vias, copper pours, and component placement.
  • Renesas recommends using an external overcurrent protection circuit, such as a current sense resistor and a comparator, to detect overcurrent conditions. The application note (R01AN3601EU0100) provides a reference design for overcurrent protection.
  • Renesas recommends a power-up sequence of VCC, then VDD, and finally EN (enable) to ensure proper device operation. This sequence is described in the datasheet, but it's often overlooked.
  • Renesas provides an I2C bus troubleshooting guide in their application note (R01AN3601EU0100) which covers common issues, such as bus contention, clock stretching, and slave address conflicts.
  • While the datasheet specifies an operating temperature range of -40°C to 125°C, Renesas recommends derating the device's performance at temperatures above 85°C to ensure reliability and prevent thermal shutdown.
