N623PA package

Interfaces & Control

Host Interface: UART (with AT Command set), SPI
Development: All key MCU pins (GPIO, ADC, etc.) are accessible for secondary development.
Package: Surface-Mount Device (SMD)

Get to Market Faster: We handle the complex RF design and regulatory certifications (for supported bands), allowing you to focus on your application. The integrated AT command set slashes development time.
Design for Battery Life: The ultra-low power architecture of the CC1311R3, combined with our power-optimized design, ensures your product can run for years on a single battery.
Solve Long-Range Challenges: Stop worrying about connectivity. With its high output power and excellent receiver sensitivity, the N623PA provides the reliable, long-range link your application needs, even in challenging environments.
A Platform for Your Projects: The powerful onboard MCU offers ample processing power and GPIO to add intelligence and functionality directly to the module, reducing system complexity and cost.

Ordering Code	Core ICs	Frequency	Output Power
N623PA-868M	CC1311R3 + CC1190	860 - 880 MHz	+27 dBm
N623PA-915M	CC1311R3 + CC1190	910 - 930 MHz	+27 dBm

Custom frequency variants and conformance pre-certification are available upon request.

Simple Selection Guide:

Choose the N62xPA Series (620/621/624) if you are building a unique, proprietary protocol and have the resources for full-stack development. Select based on required Flash size.
Choose the N624PA if your project requires standard protocols (WM-Bus/Wi-SUN) or your primary goal is to minimize development time and risk.
