Kufotokozera Kwantchito

Mutuwu ukufotokoza ma module ndi ntchito zophatikizidwa mu ESP32.

CPU ndi Memory Internal
ESP32 ili ndi ma microprocessors awiri a Xtensa® 32-bit LX6 amphamvu otsika. Memory yamkati imaphatikizapo:

• 448 KB ya ROM yoyambira ndi ntchito zazikulu.
• 520 KB ya pa-chip SRAM ya data ndi malangizo.
• 8 KB ya SRAM mu RTC, yomwe imatchedwa RTC FAST Memory ndipo ingagwiritsidwe ntchito posungira deta; imafikiridwa ndi CPU yayikulu panthawi ya RTC Boot kuchokera munjira ya Deep-sleep.
• 8 KB ya SRAM mu RTC, yomwe imatchedwa RTC SLOW Memory ndipo ikhoza kufikiridwa ndi co-processor panthawi ya Kugona-Kugona.
• 1 Kbit of eFuse: 256 bits amagwiritsidwa ntchito pa dongosolo (MAC address ndi chip configuration) ndipo ma bits 768 otsala amasungidwa kwa makasitomala, kuphatikizapo flash-encryption ndi chip-ID.

Flash yakunja ndi SRAM
ESP32 imathandizira ma flash angapo akunja a QSPI ndi tchipisi ta SRAM. ESP32 imathandiziranso kubisa / kumasulira kwa hardware kutengera AES kuti iteteze mapulogalamu ndi deta ya opanga ku Flash.

ESP32 imatha kulumikiza kung'anima kwa QSPI ndi SRAM kudzera pa cache zothamanga kwambiri.

• Kuwala kwakunja kumatha kujambulidwa kukhala malo okumbukira malangizo a CPU ndi malo owerengera okha nthawi imodzi.
  • Kung'anima kwakunja kukajambulidwa mu malo okumbukira malangizo a CPU, mpaka 11 MB + 248 KB ikhoza kujambulidwa panthawi imodzi. Dziwani kuti ngati oposa 3 MB + 248 KB ajambulidwa, ntchito ya cache idzachepetsedwa chifukwa cha kuwerengedwa mongopeka ndi CPU.
  • Kung'anima kwakunja kukajambulidwa kukhala malo owerengera owerengera okha, mpaka 4 MB imatha kujambulidwa nthawi imodzi. Kuwerenga kwa 8-bit, 16-bit ndi 32-bit kumathandizidwa.
• SRAM yakunja imatha kujambulidwa kukhala malo okumbukira data a CPU. Kufikira 4 MB kumatha kujambulidwa nthawi imodzi. Kuwerenga ndi kulemba kwa 8-bit, 16-bit ndi 32-bit kumathandizidwa.

ESP32 imaphatikiza kung'anima kwa 8 MB SPI ndi 8 MB PSRAM kwa malo ambiri okumbukira.
