CC1350F128RSMT

RF Transceiver ICS Overview

The CC1350F128RSMT is a SimpleLink ultra-low-power dual-band wireless microcontroller from Texas Instruments. It integrates an ARM Cortex-M3 core with 128 kB of flash memory and 20 kB of SRAM. The device supports sub-1 GHz (300 MHz to 930 MHz) and 2.4 GHz (2.4 GHz to 2.4835 GHz) ISM bands, enabling multi-protocol connectivity including Bluetooth Low Energy. It features a maximum clock frequency of 48 MHz, an 8-channel 12-bit ADC, and operates within a voltage range of 1.8 V to 3.8 V. Packaged in a 32-VQFN (4x4) surface-mount format, it is designed for low power consumption applications.

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the component meets RoHS compliance requirements for your region. Ensure the design accounts for humidity sensitivity handling procedures as specified in the datasheet. Validate that the 32-VQFN package dimensions align with your PCB footprint constraints before finalizing procurement.

RF Transceiver ICS Selection Notes

Select this model for designs requiring both sub-1 GHz and 2.4 GHz capabilities without separate RF chips. It serves as a direct replacement for legacy three-chip solutions, reducing bill-of-materials complexity. Choose this part if the application demands high integration and extended range up to 20 km. Ensure the host system can support the required interface protocols such as SPI, I2C, and UART for peripheral communication.

RF Transceiver ICS Part Context

This component belongs to the Texas Instruments SimpleLink family of wireless MCUs. It is part of the CC13xx series, which focuses on ultra-low-power connectivity. The CC1350 variant specifically targets cost-sensitive applications needing dual-band support. It complements higher-performance models like the CC26xx series by offering a balance of price and functionality for simpler network topologies.

RF Transceiver ICS Replacement Considerations

Public confirmed substitute part numbers include CC1350F128RSMR, which shares identical electrical specifications but differs in packaging configuration.
