CC1111F8RSP

RF Transceiver ICS Overview

The CC1111F8RSP is a System-on-Chip (SoC) device from Texas Instruments, integrating an 8051 microcontroller core with a Sub-1 GHz RF transceiver. It operates within the ISM band, supporting frequencies of 300 MHz, 348–782 MHz, 391 MHz, 464 MHz, and 928 MHz. The chip features 8 kB of program memory and 1 kB of data RAM. Key electrical specifications include a maximum data rate of 500 kbps, an output power of 10 dBm, and a receiver sensitivity of -112 dBm. The receive supply current is 16.2 mA. It functions within a temperature range of -40°C to +85°C and is housed in a QFN-36 package.

RF Transceiver ICS Feature Summary

• Integrates an 8051 MCU core with a Sub-1 GHz RF transceiver on a single chip
• Supports multiple ISM frequency bands for global wireless communication flexibility
• Provides high receiver sensitivity and moderate output power for reliable link budgets

RF Transceiver ICS Applications

• Wireless sensor networks requiring low-power connectivity
• Industrial control systems utilizing Sub-1 GHz protocols
• Remote monitoring and telemetry applications

RF Transceiver ICS Procurement Notes

Verify that the specific order quantity aligns with the manufacturer's standard packaging configuration, as indicated by the factory pack size of 490 units. Ensure that the procurement channel provides valid traceability documentation consistent with Texas Instruments standards. Confirm that the received components match the CC1111F8RSP part number exactly, including any suffix designators, to guarantee compatibility with the intended PCB footprint and electrical requirements. Check for moisture sensitivity level compliance prior to assembly processing.

RF Transceiver ICS Selection Notes

Select this component when a combined MCU and RF solution is required for Sub-1 GHz applications. The 8 kB flash size limits complex firmware implementations compared to higher-capacity variants like the CC1111F32RSP. Consider the QFN-36 package constraints for thermal management and layout. Verify that the 8051 architecture meets the development team's software expertise and toolchain availability. Evaluate if the 16.2 mA receive current fits within the system's power budget constraints.

RF Transceiver ICS Part Context

The CC1111F8RSP belongs to the CC1110-CC1111 series of low-power SoCs. It shares architectural similarities with the CC1110 but includes integrated USB capabilities. Compared to the CC1111F32RSP, it offers reduced memory capacity (8 kB vs 32 kB flash). It is designed for cost-sensitive applications where moderate code space suffices. The device complements TI's broader portfolio of wireless MCUs, targeting markets needing integrated radio and processing without external components.

RF Transceiver ICS Replacement Considerations

The CC1111F32RSP serves as a direct functional substitute with increased memory capacity. The CC1110F8RHHR is a variant with different pinout and memory characteristics. Cross-model selection requires verification of package compatibility and firmware adaptation.
