+# ESP32-P4-dat
3
+
4
+The ESP32-P4 is a high-performance microcontroller in Espressif's ESP32 series, aimed at advanced applications that require robust processing power and efficient communication. Here are its most significant features:
5
+
6
+### **1. High-Performance Processor**
7
+- **Dual-Core Tensilica Processor**: The ESP32-P4 features a powerful dual-core Tensilica processor running at up to **400 MHz**, making it suitable for compute-intensive tasks.
8
+- **AI Acceleration**: Supports applications in artificial intelligence (AI) and machine learning (ML), thanks to its enhanced processing capabilities.
9
+
10
+### **2. Advanced Memory Architecture**
11
+- **Large On-Chip RAM**: Includes **up to 768 KB SRAM**, enabling efficient data handling for complex applications.
12
+- **External Memory Support**: Compatible with external Flash and PSRAM for scalable memory requirements.
13
+
14
+### **3. Peripheral Integration**
15
+- **Rich Peripheral Set**:
16
+ - Multiple SPI, UART, I2C, and I2S interfaces for versatile communication.
17
+ - High-speed USB OTG support for USB-based applications.
18
+ - CAN bus for industrial and automotive applications.
19
+ - ADCs and DACs for analog input/output.
20
+- **Motor Control**: Enhanced features for motor control applications, such as PWM and quadrature encoders.
21
+
22
+### **4. Connectivity**
23
+- **No Wi-Fi or Bluetooth**: Unlike other ESP32 modules, the ESP32-P4 focuses on standalone performance and peripheral expansion rather than wireless communication.
24
+- **Custom Connectivity Options**: It can work alongside wireless-enabled modules like ESP32-S3 to add advanced processing without duplicating Wi-Fi or Bluetooth.
25
+
26
+### **5. Power Efficiency**
27
+- **Low Power Modes**: Optimized for ultra-low-power applications with multiple sleep modes.
28
+- **Dynamic Frequency Scaling**: Reduces power consumption during less demanding tasks.
29
+
30
+### **6. Security**
31
+- **Integrated Security Features**:
32
+ - Hardware Cryptographic Accelerators.
33
+ - Secure Boot and Flash Encryption.
34
+ - Support for Secure OTA (Over-the-Air) updates.
35
+
36
+### **7. Development Ecosystem**
37
+- Fully supported by Espressif's **ESP-IDF** development framework.
38
+- Compatibility with FreeRTOS for real-time applications.
39
+
40
+### **8. Target Applications**
41
+- Ideal for industrial automation, robotics, motor control, edge computing, and AI/ML applications.
42
+- Works as a companion processor to wireless-enabled ESP32 devices for offloading compute-heavy tasks.
43
+
44
+The ESP32-P4’s performance-oriented design sets it apart, catering to applications where processing power and versatile peripherals are more critical than wireless connectivity.

+Dear customer,
5
+
6
+Shipping cost by Fedex to Israel has raised recently from 35 to 50 usd, they will need an extra 15 usd to be added for your shipment.
7
+
8
+Very sorry for this issue! This shipping cost changes from time to time.
9
+
10
+There a couple of options to resolve this:
11
+
12
+- If you still want to use the express shipping option, please consider directly sending the extra cost to [email protected], and reply to the email back.
13
+
14
+- use alternative shipping methods:
15
+
16
+ - PFCEXPRESS to Israel, the estimated delivery time is about 12-25 days. This is a combination of the fast international shipment and local delivery.
17
+ - And extra shipping cost will be refunded back via the original payment method.
18
+
19
+- Order cancel, please simply let us know by email back.
