Real Time Clock for SoC Designs | Cadence IP

Real Time Clock (RTC)

A low-power, cost-effective solution for demanding applications. The Cadence® Real Time Clock (RTC) IP offers SoC integrators the advanced capabilities and support that not only meet, but exceed the requirements of high-performance designs and implementations.

Benefits

  • Complete time-of-day clock: 12/24 hour, hours, minutes, seconds, and hundredths
  • Calendar function: Day of week, date of month, month, year, century, leap-year compensation
  • Complete time-of-day clock: 12/24 hour, hours, minutes, seconds, and hundredths

The Cadence Real Time Clock IP is a binary-coded decimal (BCD) design with clock and calendar functions. It keeps track of the time of day to a resolution of one hundredth of a second with a 100Hz clock, or one second with a 1Hz clock. The calendar functionality keeps track of the day of week, day of month, month, and year with compensation for leap years.
