  • 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. ■Terminal connection RX −−−− 4574 SG 1. XIN 16. VDD 2. N.C. 15. CE1 4. / TIRQ 13. CLK 5. / AIRQ 12. DATA 6. FCON 11. CE0 8.
