CC3230S / CC3230SF SimpleLink ™ Arm® Cortex®-M4 Wi-Fi® MCUs

Ma MCU a Texas Instruments ndiabwino pa ntchito za intaneti za Zinthu (IoT)

Texas Instruments' CC3230S and CC3230SF SimpleLink™ Arm® Cortex®-M4 Wi-Fi® MCU Texas Instruments 'SimpleLink Wi-Fi CC3230s ndi CC3230SF ndi ma MCU opanda zingwe. CC3230S imaphatikizapo 256 KB ya RAM, chitetezo cha intaneti cha IoT, chizindikiritso cha makina, mafungulo, ndi mawonekedwe a chitetezo cha MCU monga kufotokozera mafayilo am'manja, kusindikiza kwa IP (chithunzi cha MCU), boot yotetezeka, ndi chitetezo cha debug. CC3230SF imamanga pa CC3230S ndipo imaphatikiza 1 MB yogwiritsa ntchito Flash yomwe ingagwiritsidwe ntchito kuphatikiza pa 256 KB ya RAM. Chepetsani zojambula za IoT ndi Wi-Fi CERTIFIED ™ wireless MCU.

Zipangazi ndi mayankho a system-on-chip (SoC) omwe amaphatikiza ma processor awiri mkati mwa chip chimodzi, kuphatikiza purosesa ya Arm Cortex-M4 MCU yokhala ndi 256 KB ya RAM yosankha ndi 1 MB yoyeserera ya Flash, processor ya network kuyendetsa Wi-Fi ndi intaneti zomveka zigawo. Njira yokhazikitsidwa ndi ROM imasokoneza kwathunthu MCU ndipo imaphatikizaponso 802.11b / g / n 2.4 GHz radio, baseband, ndi MAC yokhala ndi injini yamagetsi yolimba kwambiri.

Zipangizozi zimakhala ndi kuthekera kosavuta kolumikizana kwa zinthu ndi intaneti. Zina mwazinthu zazikulu ndi monga Bluetooth Low Energy (BLE) ndi kukhalapo kwa wailesi ya Wi-Fi 2.4 GHz (CC13x2 / CC26x2), kusankha ma antenna, mpaka mabowo 16 otetezedwa nthawi yomweyo, pempho la zikalata (CSR), satifiketi yapaintaneti (OCSP), Wi -Fi Alliance® yotsimikizika yopulumutsa mphamvu (BSS max idle, DMS, ndi proxy ARP), njira yosavutikira yotulutsira ma packet template, komanso kuthandizidwa ndi netiweki. Ma MCU awa ndi gawo la pulatifomu ya SimpleLink MCU, malo wamba, osavuta kugwiritsa ntchito otukuka potengera pulogalamu imodzi yopanga mapulogalamu (SDK) yokhala ndi zida zolemera komanso zojambula. Gulu la E2E ™ limathandizira Wi-Fi, BLE, sub-1 GHz, ndikuchitira ma MCU.

Mawonekedwe

Zoyeserera zingapo-pa-chip (SoC)
Zambiri zachitetezo, othandizira opanga amateteza zidziwitso, deta, ndi pulogalamu ya IP
Mitundu yamagetsi otsika yamagetsi ogwiritsa ntchito batire
Kukhala limodzi ndi ma radio BLE (CC13x2 / CC26x2)
Kuyenda kothandizidwa ndi netiweki
Kutentha kwamakampani: -40 ° C mpaka + 85 ° C
Wi-Fi Yotsimikizika ndi mgwirizano wa Wi-Fi
Njira yothandizira ya MCU:
- Arm Cortex-M4 pachimake pa 80 MHz
- Chikumbutso chogwiritsa ntchito: 256 KB ya RAM ndikusankha 1 MB ya Flash yotheka
- Zida zambiri zolembetsera komanso zotengera nthawi
- Zipini za 27 I / O zokhala ndi mitundu ingapo yama multiplexing

Ndondomeko yamagetsi ya Wi-Fi:
- Wi-Fi pachimake
- Ndondomeko za intaneti komanso kugwiritsa ntchito
- Makina oyendetsedwa ndi kayendedwe ka mphamvu
Zambiri zotetezera
Ndondomeko yoyendetsera mphamvu:
- Ophatikizira ophatikizika a DC / DC amathandizira ma voltages osiyanasiyana
- Njira zapamwamba zamagetsi ochepa
Mphamvu ya Wi-Fi TX: 18.0 dBm pa 1 DSSS, 14.5 dBm pa 54OFDM
Kuzindikira kwa Wi-Fi RX: -96 dBm pa 1 DSSS, -74.5 dBm pa 54 OFDM
Clock: 40.0 MHz kristalo wokhala ndi oscillator wamkati, 32.768 kHz kristalo kapena RTC yakunja
Phukusi la RGK: pini 64, 9 mm × 9 mm phukusi lochepa kwambiri la quad losasunthika (VQFN), phula la 0.5 mm

Mapulogalamu

Mapulogalamu azinthu pa intaneti:
- Zomangamanga ndi nyumba:
  - Machitidwe a HVAC ndi ma thermostats
  - Kuwonera kanema, mabelu apa kanema, komanso makamera opanda mphamvu
  - Kumanga makina achitetezo ndi ma e-maloko
  - Zoyesera utsi
  - Zoyang'anira zotayira madzi

Zipangizo zoyendera: anzeru kunyumba zakutali
Kutsata chuma
