Overview

Description

NRF52811-CAAA-R is Nordic Semiconductor’s nRF52811 SoC, a BLE-focused part in the nRF52 family. It targets small, low‑power wireless devices (beacons, sensors, wearables).
Key points
- Core and radio: 32‑bit ARM Cortex‑M4F MCU up to 64 MHz with an integrated 2.4 GHz Bluetooth Low Energy radio.
- Memory and peripherals: on‑chip flash/RAM sized for BLE apps; includes common peripherals (GPIO, timers, PWM, ADC) and serial interfaces (UART, SPI, I2C/TWI).
- Package suffix: -CAAA-R denotes the specific package/temperature variant; -R indicates tape‑and‑reel packaging suitable for production.
- Toolchain and ecosystem: supported by Nordic’s nRF5 SDK and the newer nRF Connect SDK.
- Use cases: ideal for compact, battery‑powered BLE devices where USB, Zigbee, or Thread are not required.
If you need USB or Zigbee/Thread, consider a higher‑end Nordic part (e.g., nRF52840).

Features

Concise features of NRF52811-CAAA-R:
- 64 MHz ARM Cortex-M0+ MCU
- 2.4 GHz RF transceiver for Bluetooth Low Energy; BLE 5.x features; supports proprietary 2.4 GHz protocols (and ANT on some variants)
- Memory: up to ~128 KB flash and ~24 KB RAM (variant-dependent)
- Peripherals: UART, SPI, I2C, PWM, GPIO, PPI/GPIOTE, Timers, RTC; SAADC (12-bit, multi-channel)
- Power: wide supply range 1.7–3.6 V; optimized for low power with multiple sleep modes
- Debug/Programming: SWD/JTAG support; compatible with Nordic SoftDevice/SDK
- Package: compact QFN32 form factor
- Temperature range: industrial-grade operation (typical -40°C to 85°C)
Note: exact memory and feature details can vary by exact revision/region; refer to the datasheet for precise specs of your lot.

Package

The nRF52811-CAAA-R is supplied in a 32-pin QFN package (4.0 × 4.0 mm).

Pinout

- Pin count: 32 pins (QFN-32, 5x5 mm package).
- Function: nRF52811 SoC with an integrated 2.4 GHz transceiver for Bluetooth Low Energy, plus an ARM Cortex-M0+ MCU for BLE-enabled devices and IoT wearables.

Manufacturer

- Manufacturer: Nordic Semiconductor ASA.
- What kind of company: A Norwegian fabless semiconductor company that designs and sells wireless system-on-chip (SoC) ICs (notably Bluetooth Low Energy/2.4 GHz, ANT) and modules for IoT, with manufacturing outsourced to foundries. It is publicly traded on the Oslo Stock Exchange.

Application
