SI1012-C-GM2R

RF Transceiver ICS Overview

The SI1012-C-GM2R is an RF microcontroller integrating a C8051F9XX core with an EZRadioPRO transceiver. It operates at 240–960 MHz with +13 dBm output power and -121 dBm sensitivity. The MCU features 16 kB Flash, 768 B SRAM, and a 25 MHz clock. Supply voltage ranges from 0.9 V to 3.6 V. It includes a 10-bit ADC, I2C, SPI, UART interfaces, and 15 GPIOs in a 42-LGA package.

RF Transceiver ICS Feature Summary

• Integrates an 8051-compatible microcontroller core with an ultra-low power ISM band transceiver
• Supports FSK, GFSK, and OOK modulation protocols for flexible wireless communication
• Includes programmable packet handler and auto-frequency calibration capabilities
• Features on-chip DC-DC boost converter for efficient single-cell battery operation

RF Transceiver ICS Applications

• Battery-powered home automation systems
• Smart metering applications
• Indoor monitoring and security systems

RF Transceiver ICS Procurement Notes

Verify component status as the SI1012-C-GM2R is designated as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors, noting potential minimum order quantity restrictions due to end-of-life planning. Ensure compliance with RoHS3 specifications and check moisture sensitivity level ratings before procurement.

RF Transceiver ICS Selection Notes

Select this component for designs requiring integrated RF and MCU functionality in a compact footprint. Consider the 16 kB memory limit and 25 MHz processing speed for application complexity. Verify that the 240–960 MHz frequency range aligns with regional ISM band regulations. Evaluate the 42-LGA package requirements for PCB layout and thermal management.

RF Transceiver ICS Part Context

Part of the Silicon Labs Si10xx series, which combines C8051F9XX MCUs with EZRadioPRO transceivers. This family targets low-power wireless applications, offering high link budgets and minimal external components. The SI1012 variant specifically provides +13 dBm output power, distinguishing it from higher-power siblings like the Si1010.
