DESKRIPSI FUNGSIONAL

This chapter describes the ESP32-PICO-D4 various modules and functions

CPU jeung mémori

ESP32-PICO-D4 ngandung dua kakuatan low Xtensa® 32-bit LX6 MCU. Memori on-chip ngawengku:

• 448-KB ROM, sarta program dimimitian pikeun nelepon fungsi kernel
• Pikeun 520 KB instruksi jeung neundeun data chip SRAM (kaasup memori flash 8 KB RTC)
• memori flash RTC 8 KB SRAM, nalika RTC bisa dimimitian dina mode Deep-sare, sarta pikeun nyimpen data diaksés ku CPU utama.
• Memori lambat RTC, tina 8 KB SRAM, tiasa diaksés ku coprocessor dina modeu Deepsleep
• Tina 1 kbit eFuse, anu mangrupikeun sistem khusus 256 bit (alamat MAC sareng set chip); sésana 768 bit ditangtayungan pikeun program pamaké, program Flash ieu ngawengku enkripsi sarta ID chip

DESKRIPSI neundeun

Flash éksternal sareng SRAM
ESP32 ngadukung sababaraha lampu kilat QSPI éksternal sareng mémori aksés acak statik (SRAM), gaduh énkripsi AES dumasar-hardware pikeun ngajagaan program sareng data pangguna.

• ESP32 aksés éksternal QSPI Flash na SRAM ku cache. Nepi ka 16 MB rohangan kode Flash éksternal dipetakeun kana CPU, ngarojong aksés 8-bit, 16-bit jeung 32-bit, sarta bisa ngaéksekusi kode.
• Up to 8 MB external Flash and SRAM mapped to the CPU data space, support for 8-bit, 16-bit and 32-bit access. Flash supports only read operations, SRAM supports read and write operations. ESP32-PICO-D4 4 MB of integrated SPI Flash, the code can be mapped into CPU  space, support for 8-bit, 16-bit and 32-bit access, and can execute code. Pin GPIO6 ESP32 of, GPIO7, GPIO8, GPIO9, GPIO10 and GPIO11 for connecting module integrated SPI Flash, not recommended for other functions.

KRISTAL

• ESP32-PICO-D4 ngahijikeun osilator kristal 40 MHz.

Manajemén RTC jeung konsumsi kakuatan low

ESP32 ngagunakeun téhnik manajemén kakuatan canggih bisa switched antara mode hemat daya béda. (Tingali Tabel 5).

• Modeu hemat daya
  • Mode aktip: chip RF beroperasi. Chip tiasa nampi sareng ngirimkeun sinyal sora.
  • modem-sare mode: CPU bisa ngajalankeun, jam bisa jadi ngonpigurasi. Wi-Fi / baseband Bluetooth sareng RF
  • Modeu sare lampu: CPU ditunda. RTC jeung mémori jeung périferal ULP operasi coprocessor. Sagala acara hudang-up (MAC, host, timer RTC atanapi interrupt éksternal) bakal hudang chip.
  • Modeu sare jero: ngan ukur mémori RTC sareng périferal dina kaayaan berpungsi. Data konektipitas Wi-Fi sareng Bluetooth disimpen dina RTC. ULP coprocessor tiasa jalan.
  • Modeu hibernasi: 8 MHz osilator sarta diwangun-di coprocessor ULP ditumpurkeun. Memori RTC pikeun mulangkeun catu daya dipotong. Ngan hiji timer jam RTC lokasina dina jam slow sarta sababaraha RTC GPIO jam gawé. Jam RTC RTC atanapi timer tiasa hudang tina modeu Hibernasi GPIO.
• Modeu sare jero
  • mode sare patali: modeu ngahemat kakuatan switching antara Active, Modem-sare, mode Lampu-sare. CPU, Wi-Fi, Bluetooth, sareng interval waktos prasetél radio kedah dihudangkeun, pikeun mastikeun sambungan Wi-Fi / Bluetooth.
  • Métode ngawaskeun sénsor Ultra Low-kakuatan: sistem utama nyaéta mode Saré jero, coprocessor ULP dibuka atanapi ditutup sacara périodik pikeun ngukur data sénsor. Sensor ngukur data, coprocessor ULP mutuskeun pikeun hudang sistem utama.
