The device can operate over the –40 to 85 °Ctemperature range without requiring an external crystal reference source reducingboard area and BOM cost. The device includes an 8 kB non volatile memory blockfor programming the user's application along with a 12 kB ROM of embeddedsupport code for use in the user's application. The Si4010 includes SiliconLaboratories' 2-wire C2 Debug and Programming interface, which allowscustomers to download their code during the development stage into the on-boardRAM for testing and debug prior to programming the NVM.The Si4010 is designed for low power battery applications with standby currents ofless than 10 nA to optimize battery life and features automatic wake on buttonpress support to efficiently move from the standby to active mode state withminimal customer code support. Built in AES-128 hardware encryption along witha 128-bit EEPROM can be used to create robust data encryption of thetransmitted packets. A unique 4-byte serial number is programmed into eachdevice ensuring non-overlapping device identifiers.The RF transmitter features a high efficiency PA capable of delivering outputpower up to 10 dBm and includes an automatic antenna tuning algorithm. Thisalgorithm adjusts the antenna tuning at the start of each packet transmission foroptimal output power minimizing the impact of antenna impedance changes dueto the remote being held in a user hand. The devices supports FSK and OOKmodulations and includes automatic output power shaping to reduce spectralspreading and ease regulatory compliance. The output frequency can be adjustedvia software over the entire 27 to 960 MHz range. The output data rate is softwareadjustable up to a maximum rate of 100 kbps.Ordering Information:Pin Assignments14-Pin SOIC10-Pin MSOPPatents pendingSee page 15.
