Nordic Semiconductor RF Switch, 32-Pin QFN Package, CMOS Technology, SPI Interface NRF9E5

Nordic Semiconductor NRF9E5 is a high-performance RF Switch SoC designed for sub-1GHz ISM band wireless transceiver applications. It integrates a 32-pin QFN compact package with CMOS technology, supporting communication primarily through an SPI interface.

The device operates in 433 MHz, 868 MHz, and 915 MHz ISM bands with channel spacing of 100 kHz for 433 MHz and 200 kHz for 868/915 MHz bands, enabling versatile frequency selection. Its modulation technique utilizes Gaussian Frequency Shift Keying (GFSK) with Manchester encoding for reliable data transmission at 50 kbps.

Powered within a voltage range from 1.9 V to 3.6 V, the NRF9E5 provides a robust solution for wireless data communication demands. The integrated 8051 microcontroller core with 4 KB RAM, 256 bytes data RAM, and 512 bytes bootloader ROM supports local processing and bootloader functionality via external EEPROM SPI bus.

This RF switch delivers a receiver sensitivity of -100 dBm at a bit error rate of 0.1%, with an RF output power of up to +10 dBm, enabling long-range performance for applications like alarm systems, home automation, remote controls, surveillance, automotive telemetry, keyless entry, toys, and IoT local communications.

The device offers four 10-bit ADC channels sampling up to 80 ksps, up to 12 GPIOs, SPI and UART serial interfaces, and a real-time clock with several power-saving modes controllable through software.

Its compact 5 mm by 5 mm by 0.85 mm QFN package facilitates surface mounting on PCBs. The operating temperature range of -40°C to +85°C makes it suitable for industrial and automotive environments.

Manufactured in the Philippines, this RF Switch complies with no specific standards or approvals but meets the demanding needs of wireless communication systems. Supports multiple ISM-band RF frequencies for versatile applications.

Integrated MCU allows embedded control without external processors. Low power operation with hardware protocol support via ShockBurst™. Robust modulation and error checking ensure reliable data transfer. Compact packaging and surface mount compatibility for modern electronics.
