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

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.

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.

 SPI bus for applications with microcontroller

 Clock output for microcontroller

 Integrated programmable crystal load capacitor

 Multiple event handling options for wake-up activation

 Push-button event handling with switch de-bounce

 Wake-up timer

 Low battery detection

 2.2 to 5.4 V supply voltage
