CC1111F8RSPG3 Equivalent & Substitute Parts

Part Overview

The CC1111F8RSPG3 is a Texas Instruments RF transceiver with integrated microcontroller designed for General ISM band applications below 1GHz. This device combines RF transmission and reception capabilities with an embedded MCU, supporting multiple modulation schemes across the 300MHz–348MHz, 391MHz–464MHz, and 782MHz–928MHz frequency bands. The part is currently listed as Obsolete, making identification of compatible substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CC1111F8RSPG3 is determined by strict equivalence across the following critical parameters:

• RF Transceiver Type: TxRx + MCU integrated architecture
• Frequency Coverage: Support for 300MHz–348MHz, 391MHz–464MHz, and 782MHz–928MHz bands
• Modulation Support: 2FSK, ASK, GFSK, MSK, OOK capability
• Data Rate: 500kBaud maximum
• RF Performance: 10dBm output power and -112dBm sensitivity
• Memory Configuration: 8kB Flash and 1kB SRAM
• Interface Set: I2S, USART, and USB serial interfaces
• GPIO Availability: 19 GPIO pins
• Power Supply: 3V–3.6V operation
• Package Form Factor: 36-VFQFN with exposed pad
• Compliance: ROHS3 compliance and MSL 3 rating

The CC1111F8RSP meets all substitution criteria as a direct equivalent, with the primary distinction being packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The CC1111F8RSP is a direct functional and electrical equivalent to the CC1111F8RSPG3. All electrical parameters, RF performance specifications, memory configuration, interface capabilities, and compliance certifications are identical. The primary distinction is product status: the CC1111F8RSPG3 is Obsolete, while the CC1111F8RSP maintains Active status from Texas Instruments.

For new designs or system refreshes, the CC1111F8RSP is the appropriate selection due to its Active product status and continued manufacturer support. For legacy system maintenance where CC1111F8RSPG3 inventory is unavailable, the CC1111F8RSP provides complete functional compatibility with identical electrical and RF characteristics.

The packaging format difference (Tape and Reel versus Tray) does not affect electrical performance or PCB integration, only supply chain and handling logistics.

Frequently Asked Questions (FAQ)

Q: Can CC1111F8RSP replace CC1111F8RSPG3 in existing designs?

A: Yes. All electrical, RF, and functional parameters are identical. The devices are pin-compatible and functionally equivalent. Packaging format differs (Tray versus Tape and Reel) but does not affect circuit operation or PCB assembly.

Q: What is the significance of the product status difference?

A: CC1111F8RSPG3 is Obsolete, indicating Texas Instruments no longer manufactures or supports this part number. CC1111F8RSP is Active, meaning it remains in production with ongoing manufacturer support. For new designs, Active parts are preferred for long-term availability and support.

Q: Are the RF performance specifications identical?

A: Yes. Both parts deliver 10dBm output power, -112dBm sensitivity, and support the same frequency bands (300MHz–348MHz, 391MHz–464MHz, 782MHz–928MHz) with identical modulation schemes (2FSK, ASK, GFSK, MSK, OOK).

Q: Do the parts have the same memory configuration?

A: Yes. Both contain 8kB Flash and 1kB SRAM with identical serial interfaces (I2S, USART, USB) and 19 GPIO pins.

Q: Is the 36-VFQFN package identical between both parts?

A: Yes. Both use the 36-VFQFN Exposed Pad package with identical pinout and mechanical dimensions. The packaging format (Tray versus Tape and Reel) affects supply and handling only, not electrical or mechanical compatibility.

Q: Are both parts ROHS3 compliant?

A: Yes. Both CC1111F8RSPG3 and CC1111F8RSP are ROHS3 compliant with MSL 3 rating (168 Hours).
