STMicroelectronics STNRG328S Switching Controllers Digital Controller

Nhanganyaya

• Gwaro iri rinotsanangura maitiro ekugadzirisa zvakare EEPROM ndangariro ye STNRG328S mudziyo wakaiswa pamabhodhi ane STC/HSTC topology. Iyo nzira inosanganisira kurodha binary file stsw-stc mune hex fomati uchishandisa USB/TTL-RS232 tambo adapta.
• The example pazasi inoratidza bhodhi ine STC topology uye STNRG328S yakaiswa. Iyo dhizaini yakavakirwa paX7R zvikamu
  (switch capacitors uye resonant inductors) pachiyero chekushandura 4: 1 (kubva pa48 V bhazi rekuisa kusvika ku12 V Vout), inokwanisa kuendesa 1 kW simba mumashandisirwo evhavha.

  

• Iyo binary kodhi stsw-stc inogona kutorwa kubva pane iyi link https://www.st.com/en/product/stnrg328s. Iyo stsw-stc inotsigira iyo PMBUS kutaurirana. Iwe unogona kuwana rondedzero yemirairo uye rumwe ruzivo nezve mudziyo panzvimbo imwe chete.
  Zvakakosha: Bata nehofisi yekutengesa yemuno paunenge uchigadzira chip kekutanga.

Zvishandiso uye zviridzwa

Zvishandiso uye zvishandiso zvinodiwa kuita maitiro ekusimudzira zvinotsanangurwa pazasi.

1. Komputa yako ine zvinotevera zvinodiwa:
   • Windows XP, Windows 7 masisitimu anoshanda
   • ingangoita 2 GB ye RAM ndangariro
   • 1 USB chiteshi
2. Installation file CDM v2.12.00 WHQL Certified.exe nokuda FTDI mutyairi nokuda USB 2.0 kuti serial UART converter. The file inogona kutorwa kubva kuST.com paSTEVAL-ILL077V1 evaluation tool firmware peji mune STSW-ILL077FW_SerialLoader subdirectory.
   • Batanidza tambo ye USB / UART muPC uye mamaboard. Kekutanga tambo yakabatana nePC, iyo FTDI USB serial inoshandura mutyairi inofanirwa kuwanikwa uye inoiswa otomatiki.
     Kana mutyairi asina kuiswa, tanga kuisa file CDM v2.12.00 WHQL Certified.exe.
   • Kana mutyairi aiswa, kutaurirana kuburikidza nechiteshi che USB kunomepu kune yemukati PC COM. Mepu inogona kusimbiswa muWindows Device maneja: [Control Panel]>[System]>[Device Manager]>[Ports].

     
3. Archive file Flash Loader Demonstrator.7z, inodiwa kuisa ST serial flash loader paPC.
   The file inogona kutorwa kubva kuST.com paSTEVAL-ILL077V1 evaluation tool firmware peji mune STSW-ILL077FW_SerialLoader subdirectory.
   • Mushure mekuisa iyo toolset, mhanya iyo inogoneka file STFlashLoader.exe. Iyo skrini inoratidzwa mumufananidzo pazasi ichaonekwa.

     
4. The .hex binary file yakagadzirwa neIAR Embedded Workbench. Chishandiso chiri mubhodhi chinofanira kunge chatovhenekwa ne firmware ine PMBUS yekutaurirana rutsigiro. Kune firmware, tinoreva STUniversalCode.
5. Micro USB tambo.
6. DC magetsi ekupa simba kune bhodhi.

Hardware setup

Ichi chikamu chinotsanangura kubatana pakati peUART tambo nemapini emudziyo. Iyo pini yemudziyo inoratidzwa pazasi:

1. Seta mapini sekutsanangurwa kwazvino patafura:
   Tafura 1. STNRG328S pin settings
   

   Jumper reference	Gadza chinzvimbo
   Pini 13 (VDDA)	+3.3V / +5V pabhodhi yakapihwa
   PIN 29 VDD	+3.3V / +5V pabhodhi yakapihwa
   Pini 1 (UART_RX)	Setwa kuUART TX yetambo
   Pin 32 (UART_TX)	Gadzirisa kuUART RX yetambo
   Pini 30 (VSS)	GND
   Pini 7 (UART2_RX)	Batanidza pasi kudzima bootloader pane yechipiri UART

2. Batanidza iyo USB yekupedzisira yeadhaputa tambo kune USB port yePC; wobva wabatanidza iyo serial end nemapini ekubatanidza socket.
   Simbisa zvinotevera zvinongedzo:
   • RX_cable = TX_devive (Pin 32)
   • TX_cable = RX_device (Pin 1)
   • GND_cable = GND_device (Pin 30)
     Imwe UART RX Pin 7 ye STNRG328S inofanira kunge yakabatana nevhu.

     

Kurodha firmware

• Nekugadziridzwa kweiyo EEPROM ndangariro ye STNRG328S mudziyo, isu tichanongedzera kune X7R-1kW bhodhi inoratidzwa muMufananidzo 1.
• Iyo stsw-stc firmware inoonekwa seyakatoiswa.
• Bhodhi rinoshandisa Pin 1 uye Pini 32 seUART. Iyo firmware inogadzirisa aya akagovaniswa I2C pini seUART nekuti inoda kugonesa iyo bootloader kuburikidza neUART. Iyi ficha inogona kuitwa nekuita iyo PMBUS kunyora kuraira kuseta iyo 0xDE kukosha ku0x0001.
• Kutumira iyo PMBUS mirairo, mushandisi anoda GUI uye interface USB / UART (ona 1.).
• Mushure mekuita murairo uyu, batanidza tambo yeUART paPin 1 nePin 32 sezvatsanangurwa pamusoro uye wotevera matanho ari pasi apa:

1. Mhanya iyo STFlashLoader.exe, hwindo riri pazasi rinoratidzwa.

   

   • Isa zvigadziriso zvinoratidzwa mumufananidzo uri pamusoro.
     Zvakakosha:
     Usadzvanye bhatani re[Next] nekukasika sezvo rinogona kuvhara hwindo renguva. Imwezve gadziriso yepini bhasikoro inodiwa usati waenderera.
   • Kune [Port Name], sarudza COM chiteshi chine chekuita ne USB/Serial converter. Windows Device Manager paPC yemushandisi inoratidza mepu yeCOM port (ona Zvishandiso uye zviridzwa).
2. Simba bhodhi ZIMA uye ON uye nekukasika (pasi pe 1 s) dzvanya bhatani re[Inotevera] mumufananidzo uri pamusoro. Iyo inotevera skrini ichaonekwa kana yakabudirira kubatana pakati pePC nebhodhi kwave kusimbiswa.

   

3. Kubva mubhokisi-bhokisi mumufananidzo uri pamusoro, sarudza STNRG kubva pane [Target] runyorwa. Hwindo idzva richaonekwa rine mepu yendangariro yeisinga zungunuke ndangariro.

   

4. Baya bhatani re[Inotevera], uye mufananidzo uri pazasi unozoonekwa.
   Kugadzira EEPROM:
   1. sarudza [ Dhawunirodha kuChishandiso]
   2. mu [Download kubva file], tarisa ku file kurodha muSNRG328S ndangariro.
   3.  sarudza [Global Erase] sarudzo.

      

5. Dzvanya [Inotevera] kuti utange maitiro ekudhaunirodha.
   Mirira kuti maitiro ehurongwa apedze uye uone kuti meseji yekubudirira mune yegirini inooneka, sezvakaratidzwa mumufananidzo uri pazasi.

   

6. Unogona kuona kuti bhinari chaiyo yakatorwa nekutarisa kuti data&code checksum ye firmware inofanana nekuburitswa.
   Maitiro aya anotsanangurwa mu STC Checksum Implemetation.docx inowanikwa pa ST.com.
