Product specification
4-digit duplex LCD car clock
PCF1179C
The number (n) is stored in a non-volatile memory which is achieved by the following steps (see Fig.6):
1.
Set SEL to V
SS
and a level of V
DD
5 V to V
PP
2.
The quartz-frequency deviation
f/f is measured and (n) is calculated (see Table 1)
3.
A first pulse t
E
is applied to the DATA input clears the EEPROM to give the highest backplane frequency
4.
The calculated pulses (n) are entered in (t
H
, t
L
). If the maximum backplane period is reached and an additional pulse
is applied the period will return to the lowest value.
5.
The backplane period is controlled and when correct fixed by applying the store pulse t
W
6.
Release SEL and V
PP
.
