1.1 Uskunalar tarkibi
The hardware of CORES3: ESP32-S3 chip, TFT screen, Green LED, Button, GROVE interface, TypeC-to-USB interface, Power Management chip and battery.
ESP32-S3 The ESP32 is a dual-core system with two Harvard Architecture Xtensa LX6 CPUs. All embedded memory,external memory and peripherals are located on the data bus and/or the instruction bus of these CPUs. With some minor exceptions (see below), the address mapping of two CPUs is symmetric, meaning that they use the same addresses to access the same memory. Multiple peripherals in the system can access embeddedmemory via DMA.

FUNKSIONAL TA'RIFI

Ushbu bobda ESP32-S3 ning turli modullari va funksiyalari tasvirlangan.
3.1.CPU VA Xotira
Xtensa® ikki yadroli 32-bitli LX7 mikroprotsessor, 240 MGts gacha

• 384 KB ROM
• 512 KB SRAM
• RTC-da 16 KB SRAM
• Bir nechta flesh va tashqi RAMga ulanish imkonini beruvchi SPI, Dual SPI, Quad SPI, Octal SPI, QPI va OPI interfeyslari
• Keshli Flash kontroller qo'llab-quvvatlanadi
• Flash In-Circuit Programming (ICP) qo'llab-quvvatlanadi

3.2.SAQLASH TAVSIFI
3.2.1. Tashqi Flash va SRAM
ESP32-S3 bir nechta tashqi flesh va RAMga ulanish imkonini beruvchi SPI, Dual SPI, Quad SPI, Octal SPI, QPI va OPI interfeyslarini qo'llab-quvvatlaydi.
The external flash and RAM can be mapped into the CPU instruction memory space and read-only data memory space. The external RAM can also be mapped into the
CPU data memory space. ESP32-S3 supports up to 1GB of external flash and RAM, and hardware encryption/decryption based on XTS-AES to protect users’programs and data in flash and external RAM.
Yuqori tezlikdagi keshlar orqali ESP32-S3 bir vaqtning o'zida quyidagilarga yordam beradi:

• External flash or RAMmapped into 32 MB instruction space as individual blocks of 64 KB
• Tashqi operativ xotira 32 KB bo'lgan alohida bloklar sifatida 64 MB ma'lumotlar maydoniga joylashtirilgan. 8-bit, 16-bit, 32-bit va 128-bit oʻqish va yozish qoʻllab-quvvatlanadi. Tashqi flesh shuningdek, 32 KB bo'lgan alohida bloklar sifatida 64 MB ma'lumotlar maydoniga joylashtirilishi mumkin, lekin faqat 8-bit, 16-bit, 32-bit va 128-bitli o'qishlarni qo'llab-quvvatlaydi.

3.3.CPU SOATI
CPU soati uchta mumkin bo'lgan manbaga ega:

• Tashqi asosiy kristall soat
• Ichki tezkor RC osilator (odatda taxminan 17.5 MGts va sozlanishi)
• PLL soati

Ilova yuqoridagi uchta soatdan soat manbasini tanlashi mumkin.
The selected clock source drives the
CPU clock directly, or after division, depending on the application. Once the CPU is reset, the default clock source would be the external main crystal clock divided by 2.
3.4.RTC AND LOWPOWER MANAGEMENT
Ilg'or quvvatni boshqarish texnologiyalaridan foydalangan holda, ESP32-S3 turli quvvat rejimlari o'rtasida almashishi mumkin. (1-jadvalga qarang).

• Faol rejim: CPU va chip radiosi yoqilgan. Chip qabul qilishi, uzatishi yoki tinglashi mumkin.
• Modem uyqu rejimi: CPU ishlaydi va soat tezligini kamaytirish mumkin. Simsiz tarmoq va radio o'chirilgan, ammo simsiz ulanish faol bo'lib qolishi mumkin.
• Lightsleep mode: The CPU is paused. The RTC peripherals, as well as the ULP coprocessor can be woken up periodically by the timer.
  Any wake-up events (MAC, host, RTC timer, or external interrupts) will wake up the chip. Wireless connection can remain active. Users can optionally decide what peripherals to shut down/keep on (refer to Figure 1), for power-saving purpose.
• Chuqur uyqu rejimi: protsessor va ko'pgina tashqi qurilmalar o'chirilgan.
  Only the RTC memory is powered on and RTC peripherals are optional. Wi-Fi connection data are stored in the RTC memory. The
  ULP protsessorlari funktsionaldir.
