Si4010 Remote Control on a Chip​

The Si4010 RF transmitter with an integrated 8051 microcontroller is the industry’s first single-chip remote control IC requiring only one external bypass capacitor, a printed circuit board, battery and an external casing with push-buttons to form a complete remote control.
Based on the proven Si500 silicon oscillator, its patented crystal-less architecture achieves ±150 ppm carrier frequency accuracy over the commercial temperature range and ±250 ppm over the industrial temperature range, which is two times as accurate as traditional low-cost SAW-based transmitters with no external crystal. The device operates over a continuous frequency range of 27 to 960 MHz and includes a programmable power amplifier (PA) with output powers of up to +10 dBm, automatic antenna tuning and PA edge-rate control to comply with FCC, ETSI and ARIB radio frequency regulations.
