CC1180RSPT Equivalent & Substitute Parts

Part Overview

The CC1180RSPT is an RF transceiver with integrated microcontroller designed for 802.15.4 and 6LoWPAN wireless applications. This device combines RF transmission and reception capabilities with an embedded MCU in a 36-pin VFQFN package. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

The CC1110F32RHHT qualifies as a substitute based on the following alignment criteria:

Matching Parameters:

Identical package format: 36-VFQFN Exposed Pad (6x6mm)
Identical device type: TxRx + MCU integrated architecture
Identical supply voltage range: 2V ~ 3.6V
Identical RX current specification: 16.2mA baseline
Identical power output: 10dBm
Identical sensitivity: -112dBm
Identical flash memory: 32kB
Identical operating temperature range: -40°C ~ 85°C
Identical RoHS3 compliance and MSL rating
Same manufacturer: Texas Instruments

Functional Differences: The CC1110F32RHHT operates under the General ISM < 1GHz standard rather than the 802.15.4 standard, with frequency coverage of 300MHz ~ 348MHz, 391MHz ~ 464MHz, and 782MHz ~ 928MHz. This provides broader frequency flexibility while maintaining the core RF transceiver and MCU integration. The substitute supports additional modulation schemes (2FSK, ASK, GFSK, MSK, OOK) and higher maximum data rate (500kBaud vs 200kbps), with expanded serial interface options (I2S, USART vs UART only).

Engineering Selection Recommendations

The CC1110F32RHHT is suitable as a substitute for the obsolete CC1180RSPT based on electrical and mechanical compatibility. Both devices share identical package geometry, supply voltage requirements, power output, sensitivity, and thermal operating range. The substitute maintains ROHS3 compliance and identical moisture sensitivity specifications.

The primary consideration for substitution is the RF standard difference: the CC1180RSPT is optimized for 802.15.4/6LoWPAN protocols, while the CC1110F32RHHT operates under the General ISM < 1GHz standard. System-level compatibility depends on whether the application can accommodate the broader frequency coverage and alternative modulation support of the substitute device. The substitute's higher maximum data rate and expanded serial interface options provide additional capability without reducing core performance parameters.

Frequently Asked Questions (FAQ)

Q: Are the CC1180RSPT and CC1110F32RHHT pin-compatible?

A: Both devices use the 36-VFQFN Exposed Pad package with identical 6x6mm dimensions. Pin compatibility requires verification against the specific pinout diagrams for each device, as RF transceiver designs may assign different functions to individual pins despite identical package formats.

Q: What is the primary difference between these two devices?

A: The CC1180RSPT implements the 802.15.4 standard with 6LoWPAN protocol support, while the CC1110F32RHHT operates under the General ISM < 1GHz standard. The frequency bands differ: CC1180RSPT covers 315MHz, 433MHz, 868MHz, and 915MHz, while CC1110F32RHHT covers 300MHz ~ 348MHz, 391MHz ~ 464MHz, and 782MHz ~ 928MHz.

Q: Can I use the CC1110F32RHHT in an existing CC1180RSPT design?

A: Substitution requires verification that the application protocol stack and frequency requirements are compatible with the General ISM < 1GHz standard. Firmware modifications may be necessary to accommodate the different RF standard and expanded modulation options.

Q: What are the power consumption differences?

A: Both devices specify 16.2mA receive current. The CC1110F32RHHT specifies a range of 16.2mA ~ 21.5mA for receive current and 18mA ~ 36.2mA for transmit current, compared to the CC1180RSPT which does not specify transmit current. The substitute's higher current range reflects its broader modulation and frequency capabilities.

Q: Are both devices RoHS compliant?

A: Yes, both the CC1180RSPT and CC1110F32RHHT are ROHS3 compliant with identical MSL rating of 3 (168 Hours).

Q: What memory differences exist between these devices?

A: Both devices provide 32kB Flash memory. The CC1110F32RHHT additionally specifies 4kB SRAM, while the CC1180RSPT does not provide SRAM specification in the available data.
