RF2430SR – RFMD

The RF2430SR, manufactured by RFMD (now Qorvo), is a 2.4 GHz ISM band System-on-Chip (SoC) transceiver designed for wireless sensor network applications. The ‘D/C 0423’ marking indicates a date code of week 23 of 2004. This device integrates a 2.4 GHz RF transceiver, a 8051 microcontroller core, and associated peripherals. Key features include support for IEEE 802.15.4 compliant protocols such as Zigbee, a programmable output power up to 0 dBm, and a receiver sensitivity of approximately -98 dBm. The integrated 8051 microcontroller allows for custom application code execution directly on the chip, minimizing external component count. The RF2430SR also features a built-in ADC, enabling direct interface with analog sensors. Power consumption is optimized for battery-powered operation, with various low-power modes available. It is typically packaged in a QLP or QFN package.
