Nā Uaki Manawa maoli-PCF8563T/F4,118

wehewehe pōkole:

ʻO ka PCF8563 he CMOS1 Real-Time Clock (RTC) a me ka kalena i koho ʻia no ka mana haʻahaʻa.
ʻai.ʻO kahi hoʻopuka uaki programmable, puka hoʻopau, a me ka mea ʻike uila haʻahaʻa
hāʻawi pū ʻia.Hoʻololi ʻia nā ʻōlelo a me nā ʻikepili āpau ma o ka laina lua ʻelua
I 2C-bus.ʻO 400 kbit/s ka māmā holo kaʻa.Hoʻonui ʻia ka helu helu inoa
ma hope o kēlā me kēia kākau a heluhelu ʻana i ka byte ʻikepili.

ʻO ka chip Real Time Clock kekahi o nā mea hoʻohana uila uila i hoʻohana nui ʻia i kēlā me kēia lā.Hāʻawi ia i ka poʻe i ka manawa manawa maoli, a i ʻole no nā ʻōnaehana uila e hāʻawi i kahi kuhikuhi manawa kikoʻī, hoʻohana nui ʻia nā ʻāpana Real Time Clock i kahi oscillator kristal kiʻekiʻe e like me ke kumu wati.ʻO kekahi mau kīʻaha uaki i mea e hāʻawi ai i ka mana nui i ka mana i lalo, akā hiki nō ke hana, ka pono no ka mana pākaukau hou.

1).Nā huahana RTC mua
ʻO nā huahana RTC mua nā mea hoʻokaʻawale pinepine me kahi awa kamaʻilio kamepiula.Loaʻa iā ia ka ʻike manawa e like me ka makahiki, ka mahina, ka lā, ka hola, ka minuke, a me ka lua ma ka puʻunaue ʻana a hōʻiliʻili i ka alapine oscillation i hana ʻia e ka aniani a hoʻouna ʻia i ka mea hana no ka hana ʻana ma o ke awa kamaʻilio kamepiula.
ʻO nā hiʻohiʻona o RTC i kēia manawa penei: port parallel ma ka laina awa mana;ʻoi aku ka nui o ka mana;hoʻohana i ka hana CMOS maʻamau;ʻO ka pūʻolo he papalua inline;ʻAʻole i loaʻa i ka chip ka kalena mau loa a me ka makahiki lele a me ka mahina hoʻololi maʻalahi i ka RTC hou, a ʻaʻole hiki ke mālama i ka pilikia makahiki 2000.I kēia manawa ua hoʻopau ʻia.
2).Nā huahana RTC waena
I ka waena o 1990s, ua puka mai kahi hanauna hou o RTC, e hoʻohana ana i kahi kaʻina CMOS kūikawā;hoemi nui ia ka mana, me ka waiwai ma'amau o 0.5μA a emi mai;ʻO 1.4V wale nō a i ʻole ka liʻiliʻi o ka uila uila;a ua lilo pū ke awa kamaʻilio kamepiula i ke ʻano serial, e like me ʻekolu uea SIO / ʻehā-wire SPI, kekahi mau huahana e hoʻohana ana i kahi kaʻa 2-wire I2C;hoʻopili i ka pūʻolo SOP / SSOP, ka leo Hoʻokomo ka pūʻulu i ka pūʻolo SOP/SSOP, a ua hoʻemi nui ʻia ka nui;
Hana: ua hoʻonui nui ʻia ke kiʻekiʻe o ka naʻauao on-chip, me ka hana alemanaka mau loa, ua lilo hoʻi ka mana hoʻopuka a maʻalahi.Ma waena o lākou, ua hoʻokuʻu ʻo Iapana RICOH i ka RTC i ka manawa o ka polokalamu tuning function (TTF) a me ka oscillator e hoʻōki i ka hana ʻike maʻalahi a haʻahaʻa loa ke kumukūʻai chip.I kēia manawa, ua hoʻohana nui ʻia kēia mau ʻāpana e nā mea kūʻai aku.
3).ʻO ka hanauna hou loa o nā huahana RTC
ʻO ka hanauna hou loa o nā huahana RTC, ma waho aʻe o ka loaʻa ʻana o nā hana āpau o ka lua o nā huahana, ua hoʻohui pū kekahi i nā hana composite, e like me ka ʻike haʻahaʻa haʻahaʻa, ka hana hoʻololi ʻana i ka pākaukau nui, ka hana leakage papa anti-paʻi, a me ka pūʻolo ponoʻī. ʻoi aku ka liʻiliʻi (0.85mm kiʻekiʻe, ʻāpana o 2mm * 2mm wale nō).

ʻO ka hewa o ka manawa ʻo Real Time Clock chip ka hapa nui mai ka chip clock chip i ka hewa alapine aniani, a ʻo ka hapa alapine aniani ke kumu nui ma muli o nā hoʻololi wela.No laila, ʻo ka mahana o ke aniani resonant frequency o ka hewa i hana ʻia e ka uku kūpono ke kī i ka hoʻomaikaʻi ʻana i ka pololei o ka uaki.Hoʻokumu ʻia ke kaʻina hana hoʻopiʻi quartz crystal resonant frequency compensation ma luna o ka hewa i ʻike ʻia o ke alapine resonant crystal me ka hoʻololi ʻana o ka mahana, e hoʻohua i kahi helu helu 1Hz no ke ʻano uku kūpono.
ʻO ka hana koʻikoʻi o RTC ʻo ia ka hāʻawi ʻana i ka hana kalena a hiki i 2099, no ka manawa, ʻaʻohe mea wikiwiki a lohi paha ka hewa, a he mea koʻikoʻi ka capacitor pili i nā ʻaoʻao peripheral o RTC, hiki iā ia ke hoʻoponopono pono i ka. pilikia pili ma waena o ke aniani a me ka RTC.
