Whakaahuatanga

Ko te PCA9554 me te PCA9554A he taputapu CMOS 16-pin e whakarato ana i nga moka e 8 o te Whanaketanga Whakarara Whakaraera Whakauru / Putanga (GPIO) mo nga tono I2C-pahi/SMBus a i whakawhanakehia hei whakarei ake i te whanau NXP Semiconductors o I2C-bus I/O expanders.Ko nga whakapainga ko te kaha ake o te taraiwa, te 5 VI/O te manawanui, te iti o te tuku o naianei, te whirihoranga I/O takitahi, te auau karaka 400 kHz, me te kohinga iti.Ka whakaratohia e nga kaiwhakawhanui I/O he otinga ngawari ina hiahiatia etahi atu I/O mo nga huringa hiko ACPI, nga pūoko, nga paatene pana, nga rama, nga kaiwhaiwhai, me era atu.Kei roto i te PCA9554/PCA9554A he rehita Whirihoranga moka-8 (Whakauru, Putanga ranei te whiriwhiringa);Rehita Tauranga Whakauru 8-bit, rehita Tauranga Huaputa 8-bit me te rehita Polarity Inversion 8-bit (mahi HIGH kaha, LOW kaha ranei).Ka taea e te rangatira o te punaha te whakahohe i nga I/Os hei whakaurunga, hei putanga ranei ma te tuhi ki nga moka whirihoranga I/O.Ko nga raraunga mo ia whakaurunga, whakaputanga ranei ka pupurihia ki roto i te rehita Tauranga Whakauru, Tauranga Huaputa ranei.Ko te polarity o te rehita panui ka taea te huri ki te rehita Polarity Inversion.Ka taea e te rangatira o te punaha te panui nga rehita katoa.Ahakoa e hototahi ana te wahitau titi-ki-titi me te I2C-pahi ki te raupapa PCF8574, me whakarereke te rorohiko na runga i nga whakapainga, ka korerohia i te Panui Taupānga AN469.Ko te PCA9554/PCA9554A te putanga haukoti-tuwhera ka whakahohehia ina rereke tetahi ahuatanga whakauru mai i tana ahua rehita Tauranga Whakauru ka whakamahia hei tohu ki te rangatira punaha kua rereke te ahua whakauru.Ka tautuhia nga rehitatanga ki o raatau uara taunoa ka arawhiti i te miihini ahua o te taputapu.E toru nga titi taputapu (A0, A1, A2) ka rerekee i te wahitau I2C-pahi mau, ka tuku kia waru nga taputapu ki te tiri i te I2C-pahi/SMBus.He rite tonu te PCA9554A ki te PCA9554 engari he rereke te wahitau I2C-pahi ka taea ki te tekau ma ono o enei taputapu (e waru o ia) i runga i te I2C-pahi/SMBus kotahi.
