Features Embedded EEPROM y Very Easy Development with RFPDK y All Features Programmable Frequency Range: 240 to 480 MHz OOK, FSK and GFSK Modulation Symbol Rate: y 0.5 to 30 ksps (OOK) y 0.5 to 100 ksps (FSK) Deviation: 1.0 to 200 kHz Output Power: -10 to +13 dBm Supply Voltage: 1.8 to 3.6 V Sleep Current: < 20 nA FCC/ETSI Compliant RoHS Compliant Module Size:17.812.85.0mm Descriptions The RFM113W is ultra low-cost, highly flexible, high performance, single-chip (G)FSK/OOK transmitters for various 240 to 480 MHz wireless applications. It is part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters, receivers and transceivers. With very low current consumption, the device modulates and transmits the data which is sent from the host MCU. An embedded EEPROM allows the frequency, output power and other features to be programmed into the chip using the CMOSTEK USB Programmer and RFPDK. Alternatively, in stock product of 433.92 MHz is available for immediate demands without the need of EEPROM programming. The RFM113W uses a 1-pin crystal oscillator circuit with the required crystal load capacitance integrated on-chip to minimize the number of external components. The device can deliver up to +13 dBm output power. It operates from a supply voltage of 1.8 V to 3.6 V, consumes 23.5 mA (FSK) when transmitting at +10 dBm output power; and leaks only 20 nA when it is in sleep state, providing superior operation life for battery powered applications. The RFM113W transmitter together with the R F M 2 1 3 W receiver enables an ultra low cost FSK RF link.

The user only needs to fill in/select the proper value of each parameter and click the “Burn” button to complete the chip configuration. No register access and control is required in the application program. See the figure below for the accessing of the EEPROM and Table 10 for the summary of all the configurable parameters of the RFM113W in the RFPDK.
