🚀 Why Choose the N521AS?

• Uncompromised Link Budget: +22 dBm output and -122 dBm sensitivity (at 1.25 kbps LRM) ensure robust, deep-indoor penetration and long-range connectivity.

• True Ultra-Low Power: Features an industry-leading < 1 µA sleep current and only 6.9 mA RX current (low-power mode) for multi-year battery life.

• Rugged & Reliable: Built-in 48 MHz TCXO, external SAW filter, and comprehensive full-pin ESD protection for harsh industrial environments.

• Global Frequency Coverage: Wide 196 – 1149 MHz tuning range covers all major Sub-1GHz ISM bands (169/433/868/915 MHz).

• Rapid Integration: Compact 19.0 × 16.0 × 3.0 mm SMD package, 4-layer PCB design, and native compatibility with TI SimpleLink™ SDK.

📊 Key Technical Specifications

🎯 Target Applications

• Smart Metering (AMR/AMI): Water, gas, and electricity meters requiring deep indoor penetration.

• Industrial IoT (IIoT): Wireless sensor networks in harsh RF environments.

• Smart City: Security systems, HVAC control, smart lighting, and parking sensors.

• Long-Range Telemetry: Agricultural sensors, asset tracking, and remote infrastructure monitoring.

• LPWAN & Proprietary Networks: Wi-SUN, TI 15-4-Stack, and custom Sub-1GHz protocols.

⚙️ Hardware Design Note: Power Sequence

For proper operation (especially when using TCXO sleep control), follow this strict power sequence:

1. Power TCXO (VTC)

2. Wait > 2 ms

3. Assert Reset (RST)

4. Configure via SPI
