Si4021 Universal ISM  
Si4021  
Band FSK Transmitter  
PIN ASSIGNMENT  
DESCRIPTION  
Silicon Labs’ Si4021 is a single chip, low power, multi-channel FSK  
transmitter designed for use in applications requiring FCC or ETSI  
conformance for unlicensed use in the 433, 868, and 915 MHz bands.  
Used in conjunction with Si4020, Silicon Labs’ FSK receiver, the Si4021  
TM  
transmitter features EZRadio  
technology, which produces a flexible, low  
cost, and highly integrated solution that does not require production  
alignments. All required RF functions are integrated. Only an external  
crystal and bypass filtering are needed for operation. The Si4021 builds on  
the features presented by the Si4020 by offering a higher output power  
and an improved phase noise characteristic. The Si4021 shares the same  
pinout and control command set as the Si4020. The Si4021 offers all of  
the frequencies as the Si4020, with the exception of the 315 MHz band.

EEPROM Mode  
This document refers to Si4021-IC Rev A1.  
See www.silabs.com/integration for any applicable  
errata. See back page for ordering information.  
The Si4021 features a completely integrated PLL for easy RF design, and  
its rapid settling time allows for fast frequency hopping, bypassing  
multipath fading and interference to achieve robust wireless links. In  
addition, highly stable and accurate FSK modulation is accomplished by  
direct closed-loop modulation with bit rates up to 115.2 kbps. The PLL’s  
high resolution allows the use of multiple channels in any of the bands.  
FEATURES  
Fully integrated (low BOM, easy design-in)  
No alignment required in production  
Fast settling, programmable, high-resolution PLL  
Fast frequency hopping capability  
Stable and accurate FSK modulation with programmable  
deviation  
Programmable PLL loop bandwidth  
Direct loop antenna drive  
Automatic antenna tuning circuit  
Programmable output power level  
Alternative OOK support  
The integrated power amplifier of the transmitter has an open-collector  
differential output that directly drive a loop antenna with programmable  
output level. No additional matching network is required. An automatic  
antenna tuning circuit is built in to avoid costly trimming procedures and  
de-tuning due to the “hand effect”.  
For low-power applications, the device supports automatic activation from  
sleep mode. Active mode can be initiated by several wake-up events (on-  
chip timer timeout, low supply voltage detection, or activation of any of the  
four push-button inputs).  
EEPROM mode supported  
The Si4021’s on-chip digital interface supports both a microcontroller  
mode and an EEPROM mode. The latter allows complete data transmitter  
operation without a microcontroller (both control commands and data are  
read from the EEPROM). Any wake-up event can start a transmission of the  
corresponding data stored in the EEPROM.
