The CC2530F128RHAR: This is the 128 kB Flash variant of the CC2530 family, designed for wireless sensor networks, home automation, and industrial IoT endpoints where the firmware image fits within 128 kB and the application requires up to 21 GPIOs for local sensor/actuator interfaces. The -97 dBm receiver sensitivity and 4.5 dBm maximum output power give a usable link budget for typical indoor mesh deployments; the 250 kbps data rate matches the Zigbee PHY standard.
