  • Builtin crystal unit allows adjustment-free efficient operation.
  • The small package makes high-density mounting possible. (SOP 14-pin)
  • Automatic calendar function (year, month, day, day of the week, hour, minute, second).
  • Automatic leap year correction. (up to 2099)
  • Builtin 30 x 4-bit S-RAM.
  • High-speed access.
  • Reference pulse output. (1024 Hz, 1/10 Hz)
  • Low current consumption. (1 µA typical)
  • Similar mounting method to that used for universal type SMD IC. Actual size
