Descripción general

Description

The NRF51822-CEAA-R7 is Nordic Semiconductor’s Bluetooth Low Energy (BLE) System-on-Chip (SoC) in the nRF51822 family. It combines an ARM Cortex‑M0 microcontroller with a 2.4 GHz BLE radio on a single chip, designed for ultra‑low‑power wireless devices such as wearables, beacons, and IoT sensors.
Variant notes: CEAA‑R7 identifies a specific package/assembly code and silicon revision for this part; exact I/O, memory, and peripherals follow the nRF51822 spec and may vary by production lot. Check the datasheet for your lot.
Key features: BLE radio with Nordic SoftDevice BLE stacks (e.g., S110/S120) to enable peripheral and/or central roles; on‑chip flash and RAM; multiple peripherals such as GPIOs, timers, UART, SPI, I2C, and PWM; cryptography engine for security.
Development: supported by Nordic’s SDK, SoftDevices, and various development kits for building BLE peripherals, beacons, and connected sensors. For precise specifications of your CEAA‑R7 lot, refer to the official Nordic datasheet/product page.

Features

Key features of NRF51822-CEAA-R7 (nRF51822 SoC):
- Bluetooth Low Energy (BLE) 4.0 compatible radio over 2.4 GHz
- 32-bit ARM Cortex-M0 MCU running up to 16 MHz
- Memory: up to 256 KB flash and 32 KB RAM
