REAL TIME CLOCK IC. of the TG - 3530SA exclusive use
RX - 4574 SG
Product Number ( please refer to Application guide )
RX - 4574 SG : Q414574Bxxxxx00
• By causing the high accuracy 32.768kHz clock (C-MOS input) such as TG - 3530 SA input,
the construction of the system of the high performance timekeeper is possible.
( Level adjustment by the C/R etc. at the time of the joint is unnecessary )
• Functions are compatible with RX - 4574 LC and RTC - 4574 series
( except 32 kHz oscillation function ).
• Comply with EU RoHS directive
Note) RX - 4574 SG is not including the crystal unit.
The external clock resources (C-MOS) of 32.768 kHz is necessary.
Please input it from a/the XIN terminal.
