概述

Description

The NRF52833-QDAA-B-R is Nordic Semiconductor’s nRF52833 SoC (nRF52 family). It combines a 32‑bit ARM Cortex‑M4F MCU (up to 64 MHz) with a 2.4 GHz transceiver that supports Bluetooth Low Energy, ANT, and proprietary 2.4 GHz protocols. It typically includes around 1 MB flash and 256 KB RAM, NFC-A tag support, and a rich peripheral set (cryptography hardware, ADC, PWM, SPI/I2C/UART, GPIO, timers) for low‑power IoT and wearables. It’s designed for multi‑protocol, secure, compact devices with good energy efficiency.
The -QDAA-B-R suffix is the specific package/ordering code for this variant, indicating the exact package type, temperature grade, and packaging/reel options. For precise details—package footprint/dimensions, operating temperature range, voltage, and regulatory notes—refer to the official nRF52833 datasheet and the product page for the QDAA-B-R variant.

Features

Here are the key features of the NRF52833-QDAA-B-R:
- 64 MHz ARM Cortex-M4F MCU (DSP/FPU)
- 2.4 GHz multi-protocol radio: Bluetooth Low Energy, ANT, and 2.4 GHz proprietary
- NFC-A tag interface
- On-chip memory: 1 MB Flash, 256 KB RAM
- Rich peripherals: UART, SPI, I2C (TW I), SPIS, QSPI, I2S, PWM, timers, QDEC; DPPI/ PPI
- 12-bit ADC and analog features (comparators)
- Hardware cryptography: AES, ECC, RNG; secure boot and flash protection
- Package: QFN48 (7x7 mm) with 48 pins (QDAA-B-R)
- Supply voltage: 1.7–3.6 V
Note: No USB interface is provided on this MCU family.

Package

QFN-48 package (QFN, 6x6 mm footprint).

Pinout

- Pin count: 49-pin QFN package (nRF52833‑QDAA).
- Primary pin functions: power (VDD/VDDH, VDDREG, GND, VBUS not present), RF antenna connection (single 2.4 GHz RF pin via matching network), SWD debug (CLK/DIO), up to ~32 configurable GPIOs with multi‑function capability, peripheral interfaces (SPI, TWI/I2C, UART/RTS/CTS), analog (SAADC inputs), timers/PWM, PDM for digital microphones, I2S-like audio interfaces, RTC, RNG, QDEC, NFC sensing pins, and various system/control pins (reset, high‑frequency/low‑frequency crystal or clock inputs). Pins are multiplexed; consult the nRF52833 datasheet and package pinout for exact signal mapping and restrictions.

Manufacturer

Manufacturer: Nordic Semiconductor ASA.
What kind of company: Nordic is a Norwegian fabless semiconductor company that designs low‑power wireless system-on-chips (the nRF series) and related software/development tools for Bluetooth Low Energy, Bluetooth mesh, Thread, Zigbee, ANT and other 2.4 GHz protocols. Headquartered in Trondheim, Norway, it is publicly listed on the Oslo Stock Exchange.

Application

- Ultra-low-power Bluetooth LE and 2.4 GHz wireless devices
- Wearables and health/fitness sensors
- Smart home/building automation (sensors, remotes, lighting, beacons)
- Industrial IoT and asset-tracking sensors
- Wireless peripherals (mice, keyboards, game controllers)
- Proximity/beacon networks and location services
- Medical and consumer electronics requiring secure BLE
