STMicroelectronics STNRG328S Kusintha Ma Controllers Digital Controller

Mawu Oyamba

• Chikalatachi chikufotokoza njira yosinthira kukumbukira kwa EEPROM kwa chipangizo cha STNRG328S choyikidwa pama board okhala ndi STC/HSTC topology. Ndondomekoyi ikuphatikizapo kutsitsa binary file stsw-stc mu mawonekedwe a hex pogwiritsa ntchito chingwe cha USB/TTL-RS232 adapter.
• Example pansipa likuwonetsa bolodi yokhala ndi STC topology ndi STNRG328S yokwezedwa. Mapangidwe ake amachokera pazigawo za X7R
  (kusintha ma capacitor ndi ma resonant inductors) pakusintha kwamitengo 4: 1 (kuchokera ku 48 V basi yolowera kupita ku 12 V Vout), wokhoza kupereka mphamvu ya 1 kW pamapulogalamu a seva.

  

• Khodi ya binary stsw-stc ikhoza kutsitsidwa pa ulalo https://www.st.com/en/product/stnrg328s. Stsw-stc imathandizira kulumikizana kwa PMBUS. Mutha kupeza mndandanda wamalamulo komanso zambiri za chipangizocho pamalo omwewo.
  Zofunika: Lumikizanani ndi ofesi yogulitsa zamalonda pamene mukukonza chip koyamba.

Zida ndi zida

Zida ndi zida zomwe zimafunikira kuti muwonjezere ndondomeko zafotokozedwa pansipa.

1. Kompyuta yanu yomwe ili ndi zofunikira izi:
   • Windows XP, Windows 7 machitidwe opangira
   • osachepera 2 GB ya RAM kukumbukira
   • 1 doko la USB
2. Kuyika file CDM v2.12.00 WHQL Certified.exe kwa FTDI dalaivala kwa USB 2.0 kuti siriyo UART Converter. The file ikhoza kutsitsidwa kuchokera ku ST.com pa STEVAL-ILL077V1 evaluation tool firmware page mu STSW-ILL077FW_SerialLoader subdirectory.
   • Lumikizani chingwe cha USB / UART mu PC ndi bolodi. Nthawi yoyamba chingwe cholumikizidwa ndi PC, FTDI USB serial converter driver iyenera kupezeka ndikuyika yokha.
     Ngati dalaivala sanayikidwe, yambitsani kukhazikitsa file CDM v2.12.00 WHQL Certified.exe.
   • Dalaivala atayikidwa, kulumikizana kudzera pa doko la USB kumajambulidwa ku PC yamkati ya COM. Mapu atha kutsimikiziridwa mu Windows Device manager: [Control Panel]>[System]>[Device Manager]>[Ports].

     
3. Sungani file Flash Loader Demonstrator.7z, yofunikira kukhazikitsa ST serial flash loader pa PC.
   The file ikhoza kutsitsidwa kuchokera ku ST.com pa STEVAL-ILL077V1 evaluation tool firmware page mu STSW-ILL077FW_SerialLoader subdirectory.
   • Mukatha kuyika chida, yambitsani zomwe mungachite file STFlashLoader.exe. Chophimba chomwe chikuwonetsedwa pachithunzichi chidzawonekera.

     
4. The .hex binary file yopangidwa ndi IAR Embedded Workbench. Chipangizo chomwe chili m'bwalo chiyenera kuyatsidwa kale ndi firmware yokhala ndi chithandizo cholumikizirana cha PMBUS. Kwa firmware, timatchula STUniversalCode.
5. Yaying'ono USB chingwe.
6. Mphamvu ya DC yokhala ndi mphamvu pa board.

Kupanga kwa Hardware

Gawoli likufotokoza kulumikizana pakati pa chingwe cha UART ndi mapini achipangizo. Pinout ya chipangizo ikuwonetsedwa pansipa:

1. Khazikitsani zikhomo monga zafotokozedwera patebulo ili:
   Table 1. STNRG328S zoikamo pini
   

   Zolemba za Jumper	Ikani malo
   Pin 13 (VDDA)	+ 3.3V / + 5V pa bolodi yoperekedwa
   PIN 29 VDD	+ 3.3V / + 5V pa bolodi yoperekedwa
   Pin 1 (UART_RX)	Khazikitsani ku UART TX ya chingwe
   Pin 32 (UART_TX)	Khazikitsani ku UART RX ya chingwe
   Pin 30 (VSS)	GND
   Pin 7 (UART2_RX)	Lumikizani pansi kuti mulepheretse bootloader pa UART yachiwiri

2. Lumikizani mapeto a USB a adapter chingwe ku doko la USB la PC; kenako gwirizanitsani mapeto a seriyo ndi zolumikizira pini za socket.
   Tsimikizirani zolumikizira zotsatirazi:
   • RX_cable = TX_devive (Pin 32)
   • TX_cable = RX_device (Pin 1)
   • GND_cable = GND_device (Pin 30)
     UART RX Pin 7 ina ya STNRG328S iyenera kulumikizidwa pansi.

     

Kutsitsa firmware

• Pakukonzanso kukumbukira kwa EEPROM kwa chipangizo cha STNRG328S, tidzanena za bolodi la X7R-1kW lomwe likuwonetsedwa pa Chithunzi 1.
• The stsw-stc firmware imatengedwa kuti yakhazikitsidwa kale.
• Gululi limagwiritsa ntchito Pin 1 ndi Pin 32 ngati UART. Firmware imakonza mapini a I2C awa omwe amagawidwa ngati UART chifukwa imayenera kuyatsa bootloader kudzera mu UART. Izi zitha kukhazikitsidwa polemba lamulo la PMBUS kuti muyike mtengo wa 0xDE kukhala 0x0001.
• Kuti mutumize malamulo a PMBUS, wosuta amafunikira GUI ndi mawonekedwe a hardware USB/UART (onani 1.).
• Mukamaliza kulamula, lumikizani chingwe cha UART pa Pin 1 ndi Pin 32 monga tafotokozera pamwambapa ndipo tsatirani njira zotsatirazi:

1. Kuthamanga STFlashLoader.exe, zenera pansipa likuwonetsedwa.

   

   • Ikani makonda omwe akuwonetsedwa pachithunzi pamwambapa.
     Zofunika:
     Osadina batani la [Chotsatira] nthawi yomweyo chifukwa lingatseke zenera la nthawi. Kuyikanso njinga panjinga kumafunika musanapitilize.
   • Pa [Port Name], sankhani doko la COM lolumikizidwa ndi USB/Serial converter. Windows Device Manager pa PC wogwiritsa ikuwonetsa mapu a doko la COM (onani Zida ndi zida).
2. Yatsani bolodi ZIMIMA NDI KUYANTHA ndipo nthawi yomweyo (osakwana 1 s) dinani batani la [Kenako] pachithunzi pamwambapa. Chophimba chotsatira chidzawoneka ngati kugwirizana bwino pakati pa PC ndi bolodi kwakhazikitsidwa.

   

3. Kuchokera m'bokosi la zokambirana lomwe lili pamwambapa, sankhani STNRG kuchokera pamndandanda wa [Target]. Windo latsopano lidzawoneka ndi mapu okumbukira a kukumbukira kosasunthika.

   

4. Dinani pa batani la [Chotsatira], ndipo chithunzi chili m'munsichi chidzawonekera.
   Kupanga pulogalamu ya EEPROM:
   1. sankhani [Koperani ku Chipangizo]
   2. mu [Koperani kuchokera file], sakatulani ku file kutsitsa mu kukumbukira SNRG328S.
   3.  sankhani njira ya [Global Erase].

      

5. Dinani [Kenako] kuti muyambe kukopera.
   Yembekezerani kuti pulogalamuyo ithe ndikuwonetsetsa kuti uthenga wopambana wobiriwira ukuwonekera, monga zikuwonekera pachithunzichi.

   

6. Mutha kutsimikizira kuti binary yolondola yatsitsidwa powona kuti data&code checksum ya firmware ikufanana ndi kutulutsidwa.
   Njirayi ikufotokozedwa mu STC Checksum Implemetation.docx yomwe ikupezeka pa ST.com.
