LC6514B

Fig. 7 Initial Reset Timing

τVDD : Power supply rise time constant

τRES : RES pin rise time constant

Fix C, R so that τVDD ≤τRES,tOSC≥10ms is

yielded. (tOSC : OSC stabilized time)

CR OSC characteristic of LC6514B

Fig. 8 shows the CR OSC characteristic of the LC6514B. For the variation range of CR OSC frequency of the

LC6514B, the following is guaranteed at external consatants of Cext=220pF, Rext=6.8kΩ only. The outgoing inspec-

tion is performed under this condition only.

600kHz≤fCROSC≤1220kHz

( ) Ta=–30°C to +70°C

VDD=4 to 6V

If any other constants than specified above are used, the range of Rext=5k to 50kΩ, Cext=100p to 300pF must be

observed. (See Fig. 8.)

Fig. 8 fCROSC. –Rext

Note 1. The OSC frequency at VDD=5V, Ta=25°C

must be 800KHz or less.

Note 2. The OSC frequency at VDD=4 to 6V,

Ta=–30 to +70°C must be within the

operation clock frequency range

(222KHz to 1290 kHz).
