N5132 data sheet nuvoton technology corp. release date : nov - 2014 http:// www.nuvoton.com/ revision a 1 - 7 - 5.2 2 - battery application circuit note: 1. the rosc typical value is 150k ohm at 8mhz. it should be connected to gnd (vss) 2. in pcb layout, vss_spk and vss should be connected; vdd_spk and vdd should be connected . 3. 4.7uf is optional for power stability. i ts value is depends on application. 4. at 3 - battery application , v33o 0.1uf is must for power stable. in 2 - battery application, the v33o 0.1uf is optional. v33o must connect with vdd 5. in light loading application, the 0.1uf in vdd and gnd is must to filter po wer noise 6. the 0.1uf in /reset and gnd is optional for power reset stability 7. cpu interface (spi) defines as: bp10 : ssb, bp11: sclk, bp12: miso, bp13: mosi 8. as bp32 be grounding, it can control bp33 outp ut a 250hz standard frequency for the purpose of system frequency deviation measurement . as the value higher than 250hz, means system frequency too fast , then adjust rosc value be higher to slow down ; vise verse, as it lower than 2 50hz, means system frequency too slow , then adjust rosc value be lower to speed u p it . 9. the above application circuits are for reference only. no warranty for mass production.
