Espressif Systems ESP32-WROOM-32E generic Wi-Fi+BT+Bluetooth LE MCU
ESP32-WROOM-32E integrates ESP32-D0WD-V3 and has higher stability and security performance. It is a powerful, generic Wi-Fi+BT+BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming, and MP3 decoding.
- Extra security against Fault Injection Attacks
- Robust & Compact Design
- Ultra-low power consumption
- Optimized Layout
- ESP32-WROOM-32E contains a dual-core Xtensa® 32-bit LX6 MCU.
- 448 KB of ROM for booting and core functions.
- 520 KB of on-chip SRAM for data and instructions.
- 8 KB of SRAM in RTC, which is called RTC FAST Memory and can be used for data storage; it is accessed by the main CPU during RTC Boot from the Deep-sleep mode.
- 8 KB of SRAM in RTC, which is called RTC SLOW Memory and can be accessed by the co-processor during the Deep-sleep mode.
- 1 Kbit of eFuse: 256 bits are used for the system (MAC address and chip configuration) and the remaining 768 bits are reserved for customer applications, including flash-encryption and chip-ID.
