Description
The Si4010 is a fully integrated crystal-less CMOS SoC RF transmitter with an
embedded CIP-51 8051 MCU. The device can operate over the –40 to 85 °C
temperature range without requiring an external crystal reference source reducing
board area and BOM cost. The device includes an 8 kB non volatile memory block
for programming the user's application along with a 12 kB ROM of embedded
support code for use in the user's application. The Si4010 includes Silicon
Laboratories' 2-wire C2 Debug and Programming interface, which allows
customers to download their code during the development stage into the on-board
RAM for testing and debug prior to programming the NVM.
The Si4010 is designed for low power battery applications with standby currents of
less than 10 nA to optimize battery life and features automatic wake on button
press support to efficiently move from the standby to active mode state with
minimal customer code support. Built in AES-128 hardware encryption along with
a 128-bit EEPROM can be used to create robust data encryption of the
transmitted packets. A unique 4-byte serial number is programmed into each
device ensuring non-overlapping device identifiers.
The RF transmitter features a high efficiency PA capable of delivering output
power up to +10 dBm and includes an automatic antenna tuning algorithm. This
algorithm adjusts the antenna tuning at the start of each packet transmission for
optimal output power minimizing the impact of antenna impedance changes due
to the remote being held in a user hand. The devices supports FSK and OOK
modulations and includes automatic output power shaping to reduce spectral
spreading and ease regulatory compliance. The output frequency can be adjusted
via software over the entire 27 to 960 MHz range. The output data rate is software
adjustable up to a maximum rate of 100 kbps.
