SI1023-B-GM

RF Transceiver ICS Overview

The SI1023-B-GM is a system-on-chip integrating an 8051 microcontroller with a sub-GHz RF transceiver. It features a 25 MIPS processor, 16 KB ISP-Flash, and 4 KB XRAM. The EZRadioPRO transceiver supports FSK, GFSK, and OOK modulation in the ISM band. Key electrical parameters include a transmit power of 20 dBm, receive current of 18.5 mA, and transmit current ranging from 35 mA to 85 mA. It includes a 12-bit ADC, 53 I/O lines, and hardware packet processing with AES.

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'B-GM' against official Silicon Labs documentation to confirm package type and temperature range. Ensure compatibility with required development tools like Keil PK51. Confirm that the 85-VFLGA package matches the target PCB footprint. Check for any product change notifications affecting pinout or electrical characteristics before finalizing procurement.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and RF solution is required for sub-GHz ISM bands. It is suitable for designs needing hardware acceleration for packet handling and security. Consider the 8051 architecture compatibility and available peripheral resources like timers and comparators. Evaluate the power consumption profiles against battery life requirements for the intended application.

RF Transceiver ICS Part Context

The SI1023 belongs to the Si102x/3x family of RF microcontrollers from Silicon Labs. These devices are designed as standalone system-on-a-chip solutions. They combine an 8051 core with an EZRadioPRO transceiver. This integration reduces component count and board space for wireless IoT applications.

RF Transceiver ICS Replacement Considerations

Check the Si1027-B-GM for similar functionality within the same family. Verify pin-to-pin compatibility and software migration efforts if substituting with other Si102x series variants.
