Pa Marichi 24, Renesas Electronics Corporation, omwe amatsogolera padziko lonse lapansi semiconductor solution, adalengeza kukhazikitsidwa kwa Renesas Solutions Starter Kit (RSSK) ya mainjiniya omwe amagwiritsa ntchito 32-bit RX23E-A microcontrollers (MCUs). MCU ili ndi msika wotsogola wotsogola wapamwamba kwambiri (AFE). RX23E-ARSSK imaphatikiza zida, mapulogalamu, ndi zida zomwe zingagwiritsidwe ntchito kuyesa momwe chipani cha MCU chimapangidwira-kwambiri-24-bit delta-sigma (ΔΣ) A / D. Ngakhale makasitomala alibe luso la chitukuko cha AFE, amatha kuwunika molondola ma nanovolt (nV) analog performance kudzera RSSK, potero amachepetsa ntchito yachitukuko ndikufupikitsa nthawi yomwe ikufunikira kuti ayambitse malonda.
"RX23E-A ya sensor IoT ya mafakitale ndi yankho la chip-umodzi lomwe limagwirizanitsa bwino kwambiri AFE, ndipo lingathe kukwaniritsa zolondola zosakwana 0.1% popanda kuwongolera," adatero DarylKhoo, wachiwiri wa purezidenti wotsatsa malonda ku Renesas 'IoT Platform Business Unit . Yatsopano yothetsera suite imapereka njira yosavuta kwa ogwiritsa ntchito omwe amafunika kuwunika ndi kuwunika masensa osiyanasiyana, kuchepetsa nthawi yofunikira kuti apange zida zolondola kwambiri. "
Kuchokera pa board board yowunikira mpaka kukweza mapulogalamu, kuwunika kwa analog magwiridwe antchito kwambiri kumafunikira chitukuko chaukatswiri wa analog ndi ukadaulo wopanga. Kuphatikiza apo, pamene ntchito zomwe zikufunika sizingatheke, kukonza zolakwika ndikuwunika kwambiri kumakhala nthawi yambiri, zimapangitsa kuti zikhale zovuta kubweretsa malonda kumsika munthawi yake.
Bodi yatsopano yowunikira ya RSSK idapangidwa kuti ikwaniritse kuyesa kwa RX23E-AAFE. Itha kuwunika moyenera mawonekedwe a 24-bit ΔΣA / D converter mosasamala kuchuluka kwa wogwiritsa ntchito chitukuko cha analog. Bodi yowunika ili ndi ma plugable terminal block kuti mulumikizane ndi masensa osiyanasiyana popanda kugulitsa. Imakhala ndi cholumikizira (thermocouple (sensor sensor)) ndi cholumikizira cholumikizira gawo cholumikizidwa chofunikira pakuyeza thermocouple. Ogwiritsa ntchito amatha kuyamba kuyeserera mwachangu potchula zolemba zama thermocouple ndi zolemba zolemetsa (zonse ziwiri zitha kutsitsidwa patsamba la webusayiti ya Renesas), potero kuchepetsa nthawi yofunikira yopanga zida za sensor ya IoT.
Ogwiritsa ntchito amatha kulowa ndikusintha mawonekedwe osiyanasiyana a AFE ndi A / D posinthira pogwiritsa ntchito zida zamagwiritsidwe kazithunzithunzi (GUI) ya zida, ndikuwonetsa zotsatira za kutembenuka kwa A / D mu mawonekedwe amilandu ndi ma histogram, kupangitsa ntchito zoyesa dongosolo zokhudzana ndi mawonekedwe a kuyerekezera. Mothandizidwa ndi GUI, ogwiritsa ntchito amatha kuwona kutembenuka kwa A / D kumabweretsa zotsatira zenizeni nthawi, monga kugwiritsa ntchito oscilloscope.
Bodi yowunikira ikhoza kulumikizidwa ndi emulator kuti ipangitse ogwiritsa ntchito. Mothandizidwa ndi kulumikizana ndi USB, ma PC amatha kugwiritsidwa ntchito ngati pakuwunika ndi kukonza mapulogalamu. Gulu lowunikira limaphatikizapo ma RS485 ndi ma driver a Can, ma IC, omwe amagwiritsidwa ntchito kwambiri pamakina opangira mafakitale, ndipo angagwiritsidwe ntchito popanga mapulogalamu omwe amathandizira maukonde ochezera.
About RX23E-A group group
Gulu la RX23E-Gulu lopangidwa limakhala ndi 32-bit MCU, imathandizira DSP / FPU, magwiridwe antchito ndi 32MHz, opangidwira mu AFE omwe amatha kufikira zolondola zoyezera 0,1% popanda kuwerengera. Chosinthika chophatikizidwa cha ΔΣ A / D chimakhala ndi magwiridwe antchito okwana 23,6, ndipo chip chimodzi chimatha kuzindikira ntchito za analog zomwe zingatheke pokhapokha pogwiritsa ntchito MCU, Converter ya A / D yodzipereka, kapena chopitilira patsogolo mwanzeru mu zakale. Gulu lazopanga za RX23E-AMCU lidayambitsidwa mu Meyi 2019 ndipo lakhala likugwiritsidwa ntchito kwambiri pazida zopangira mafakitale monga olamulira kutentha, maselo olemetsa ndi ma stage gauge sensor models.
About Renesas Industrial Sensor Solutions
Renesas imapereka ma MCU angapo ndi ntchito zowonjezera analog zamagetsi osiyanasiyana. Gulu lazopangira RA2A1MCU limakhazikitsidwa ndi 32-bit Arm pachimake; gulu la Renesas SynergyTMS1JAMCU lili ndi ntchito zama analog ndi ntchito zophatikizika zotetezedwa, zomwe ndizoyenera ntchito zamagetsi zamagetsi zamagetsi zamphamvu zotsika mtengo. Renesas imaperekanso gulu laopanga la RL78 / I1E 16-bit MCU ndi otembenuza ophatikizika a 24-bit ΔΣA / D. Pulogalamu yake yaying'ono ya 4mm lalikulu ndi yabwino ma sensor compact sensor komanso sensor flow compact. Kuphatikiza pa ma MCU, Renesas imaperekanso mitundu yosiyanasiyana ya masensa, kuphatikiza ma sensor a kutentha ndi masensa otaya, komanso ma IC omwe amalimbikitsa miyezo monga IO-Link, RS485, ndi AS-i. Njira zothetsera izi zimathandizira kupititsa patsogolo kuphatikizira kwa zida zama mafakitale muzinthu za IoT.
