SI1064-A-GMR

RF Transceiver ICS Overview

The SI1064-A-GMR is an integrated RF transceiver and microcontroller unit (MCU) designed for sub-1 GHz ISM band applications. It operates within a frequency range of 142 MHz to 1.05 GHz, supporting specific bands including 283–350 MHz, 425–525 MHz, and 850–960 MHz. The device features an 8051 core with 64 kB of program memory and 4 kB of data RAM, running at a maximum clock frequency of 25 MHz. It includes a 10-bit ADC and supports FSK, GFSK, GMSK, MSK, and OOK modulation formats. Power supply ranges from 1.8 V to 3.8 V, with transmit currents between 18 mA and 29 mA. It utilizes an SPI interface and is housed in a 36-WFQFN exposed pad package.

RF Transceiver ICS Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors or certified partners. Confirm the specific suffix 'GMR' indicates tape and reel packaging suitable for automated surface-mount assembly. Check for recent Product Change Notifications (PCNs) regarding manufacturing site updates or material changes. Ensure design-in compliance with regional radio frequency regulations for the selected ISM band. Validate that the 36-WFQFN thermal pad requirements are met in the PCB layout for adequate heat dissipation during operation.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and RF solution reduces bill-of-materials count and board space. The integrated architecture simplifies firmware development by allowing direct register access to RF parameters. Consider the 25 MHz clock speed and 64 kB memory limits for complex protocol stacks. Evaluate the 1.8 V to 3.8 V supply range against system power constraints. Compare against discrete solutions if higher output power or advanced filtering is required beyond the integrated capabilities.

RF Transceiver ICS Part Context

The SI1064 belongs to Silicon Labs' family of integrated RF transceivers with embedded MCUs, targeting cost-sensitive and space-constrained wireless applications. It shares architectural similarities with other parts in the series but offers specific memory sizes and frequency coverage tailored for general-purpose ISM band communications. This integration approach eliminates the need for separate microcontroller and RF chip interfaces, streamlining system design.

RF Transceiver ICS Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative integrated RF-MCU solutions from Silicon Labs or other manufacturers based on pinout, memory size, and supported frequency bands.
