Nordic Semiconductor nRF52832 is a Bluetooth 4.2 LE SoC based on an ARM Cortex-M4F core that was first released about a year ago in a QFN48 package targeting IoT and Wearables. But if your application is really tight on space and the 6x6mm package is just too big, the company has just introduced a 3.0×3.2mm WL-CSP (Wafer Level Chip Scale Package ) package for nRF52832 decreasing the area to about one quarter of the QFN package
- MCU Core – ARM Cortex-M4F @ 64 MHz with DSP & FPU, 512kB Flash and 64kB RAM
- 2.4 GHz radio for ANT, Bluetooth 4.2 LE, and Gazell connectivity; 5.5mA peak RX/TX currents; on-chip RF Balun
- On-chip NFC tag
- Peripherals – 3x Master/Slave SPI, 2x Two-wire interface (I²C), UART (RTS/CTS), 3x PWM, Digital microphone interface (PDM)
- Security – AES HW encryption
- Misc – RTC
- Power Supply – 1.7V to 3.6V
nRF52832 is compatible with Nordic’s Bluetooth 4.2 stacks and supports S132 multi-role concurrent software stack, nRF5 SDK, nRF5 SDK for HomeKit, and nRF5 SDK for AirFuel (resonant wireless charging).
Nordic Semi nRF52832 WL-CSP is available now for volume production.
