SI4010-C2-GS

RF Transmitter Overview

The SI4010-C2-GS is a crystal-less CMOS System-on-Chip (SoC) RF transmitter manufactured by Silicon Labs. It integrates an 8051-compatible microcontroller core with sub-GHz radio capabilities, supporting operation across the 27 MHz to 960 MHz frequency range. The device features OOK and FSK modulation schemes with a maximum data rate of 100 kbps and delivers up to +10 dBm output power. It operates on a supply voltage between 1.8 V and 3.6 V within a temperature range of -40°C to +85°C. The component is housed in a 14-pin SOIC surface-mount package.

RF Transmitter Feature Summary

RF Transmitter Procurement Notes

Verify the specific suffix 'GS' indicates the standard tape-and-reel or tube packaging configuration as defined by Silicon Labs documentation. Confirm that the 14-pin SOIC package variant matches the design-in requirements for PCB footprint and thermal dissipation. Ensure compatibility with the C2 debug interface for firmware development and production programming workflows.

RF Transmitter Selection Notes

Select this component when a combined MCU and RF transmitter solution is required to minimize bill-of-materials count. It is suitable for designs needing integrated encryption and automatic antenna tuning without external crystals. Consider the 100 kbps data rate limit and single-band operation constraints against application throughput needs.

RF Transmitter Part Context

This part belongs to the EZRadio family of sub-GHz transceivers from Silicon Labs. It represents a simplified transmitter-only variant compared to full duplex receivers, focusing on cost-effective, low-complexity wireless links. The integration of the 8051 core distinguishes it from pure RF ICs, allowing for greater flexibility in protocol implementation.

RF Transmitter Replacement Considerations

Direct pin-to-pin replacements are limited due to the specific integration of the 8051 core and crystal-less architecture. Evaluate other SI4010 variants with different memory sizes or packages if form factor changes are acceptable. Cross-reference with Si446x series only if receiver functionality is also required, noting significant architectural differences.
