Epson Begins Volume Production of the S1S77100, the Company's First RF Transmitter IC

- The IC's compact package, low power consumption, and support for certain frequencies in the UHF band make it ideal for small RF transmitters -

    S1S77100 package type: SQFN4-24PIN (P-VQFN024-0404-0.50)

Wireless communication capabilities are used extensively in things such as home security equipment, smart meters, and restaurant call bells. Wireless communication devices must conform to wireless standards for frequency bands that are appropriate for the communication distance and speed of their specific applications, making the selection of RF transmitter ICs that meet these standard requirements increasingly important. Furthermore, the need for smaller RF transmitter ICs that consume less power is growing along with demand for wireless communication devices that offer improved designs and longer battery life.

To meet this need, Epson developed the S1S77100, an RF transmitter IC for wireless communication transmitters that supports certain frequencies in the ultra-high frequency (UHF) band. The frequencies, selectable via serial interface (SPI) control, can be set from 300 MHz to 465 MHz or from 600 MHz to 930 MHz.

A PLL1 and power amp2 are integrated into the 4 mm x 4 mm SQFN package, making it easy to configure wireless transmission functions with an external crystal oscillator. In addition, the low current consumption of 20 nA (typical) in PowerDown mode3 makes it ideal for small wireless transmitters. As a result, customers can reduce the time and effort spent on circuit design and evaluation.

Epson will help customers further improve the performance of their products and contribute to smart social infrastructure by leveraging its efficient, compact, and precision technologies to save energy, save space, and deliver exceptional precision and accuracy.
