This chapter describes the ESP32-PICO-D4 various modules and functions
CPU na ebe nchekwa
ESP32-PICO-D4 nwere Xtensa® 32-bit LX6 MCU dị obere. Ebe nchekwa on-chip nwere:
- 448-KB nke ROM, mmemme na-amalite maka oku ọrụ kernel
- Maka nkuzi 520 KB na mgbawa nchekwa data SRAM (gụnyere ebe nchekwa flash 8 KB RTC)
- Ebe nchekwa ọkụ RTC nke 8 KB SRAM, mgbe enwere ike ịmalite RTC na ọnọdụ ụra miri emi, yana maka ịchekwa data nke isi CPU nwetara.
- Ebe nchekwa RTC dị nwayọ, nke 8 KB SRAM, onye na-arụkọ ọrụ nwere ike ịnweta ya na ọnọdụ Deepsleep.
- Nke 1 kbit nke eFuse, nke bụ usoro 256-bit kpọmkwem (adreesị MAC na ihe mgbawa); 768 nke fọdụrụ echekwabara maka mmemme onye ọrụ, mmemme Flash ndị a gụnyere izo ya ezo na mgbawa mgbawa
Nkọwa nke nchekwa
Flash mpụga na SRAM
ESP32 na-akwado otutu QSPI flash mpụga na ebe nchekwa ohere ohere static (SRAM), nwere ihe nzuzo AES dabere na ngwaike iji chebe mmemme na data onye ọrụ.
- ESP32 nweta QSPI Flash mpụga na SRAM site na caching. Ihe ruru 16 MB oghere koodu Flash mpụga ka etinyere na CPU, na-akwado ohere 8-bit, 16-bit na 32-bit, ma nwee ike mebe koodu.
- 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.
CRYSTAL
- ESP32-PICO-D4 na-ejikọta oscillator kristal 40 MHz.
