There is a 8-WFDFN Exposed Pad that comes with the timer clock, which is enclosed in the packaging. In this case, the frequency of the programmable timer is set to 4.194304MHz.It is used to pack in Tape & Reel (TR) case. There is a recommended mounting type of Surface Mount.By using the programmable timer, it is possible to supply a voltage of 1.7V~5.5V to the circuit.The type of chips can be divided into Oscillator, Silicon. The operating temperature of this timer clock is 0°C~70°C. To keep the clock timer's supply current at 490μA. It is based on LTC6930. You can read the timer clock's additional feature in the follwing: TR. On operating frequency, it's available in the range of 4.194304MHz. The sum of the IC chip pins is 8 . The number of the chip's terminations sums up to 8.
