NRF52832 in nRF52832 Family
The nRF52832 family from Nordic Semiconductor is a series of highly flexible, multi-protocol SoCs designed for 2.4GHz wireless communication. Centered around a 64MHz ARM Cortex-M4 processor with a floating-point unit, these devices bridge the gap between low-power consumption and high-performance processing. They are industry-standard solutions for Bluetooth 5.3 Low Energy, ANT, and proprietary 2.4GHz protocols, offering a rich peripheral set including NFC-A tags for simplified out-of-band pairing and a digital microphone interface.

| Part Number | Package | Interfaces | RF Family/Standard | Rx Current | Tx Current | Stock |
|---|---|---|---|---|---|---|
| NRF52832-QFAA-R7 (Nordic Semiconductor ASA) | VFQFN-48 | I2S, SPI, UART | Bluetooth | 5.4mA | 7.5mA | 23,395 |
| NRF52832-QFAA-R (Nordic Semiconductor ASA) | VFQFN-48 | I2C, SPI, UART | 1GHz | 5.5mA | 5.5mA | 207,087 |
| NRF52832-QFAA-T (Nordic Semiconductor ASA) | VFQFN-48 | I2S, SPI, UART | Bluetooth | 5.4mA | 7.5mA | 12,992 |
| NRF52832-CIAA-R (Nordic Semiconductor ASA) | XFBGA-50 | I2S, SPI, UART | 1GHz | 5.4mA | 7.5mA | 88,230 |
Variants in the nRF52832 sub-family primarily differ based on their physical packaging and delivery formats. The QFAA versions utilize a 48-pin VFQFN package suitable for standard PCB assembly, while the CIAA versions are housed in a significantly smaller 50-pin WLCSP (Wafer Level Chip Scale Package) intended for space-constrained designs. Differences in suffix codes like R7 versus R typically denote tape-and-reel quantities for manufacturing.
