Product details
Overview
CC1020RUZ from Texas Instruments is a true single-chip UHF RF transceiver for narrowband systems, operating in 402–470 MHz and 804–960 MHz ISM/SRD bands with programmable frequency steps (<300 Hz in lower band), –118 dBm sensitivity at 12.5 kHz channel spacing, and support for OOK/FSK/GFSK modulation up to 153.6 kBaud - deployed in automatic meter reading (AMR) and wireless security systems.
For engineers reviewing the CC1020RUZ datasheet, CC1020RUZ pinout, CC1020RUZ application, or CC1020RUZ equivalent, this page delivers verified technical context, validated QFN-32 pin mapping, confirmed EN 300 220/FCC Part 15 compliance parameters, real-world RSSI accuracy (±3 dB), and documented alternatives for narrowband low-power UHF designs.
Technical Context
The CC1020RUZ implements a low-IF receiver architecture with integrated image rejection mixer, digital demodulator, and programmable channel filter bandwidth (9.6–307.2 kHz), enabling high selectivity in 12.5/25 kHz channel-spaced systems. Its PLL-based frequency synthesizer supports crystal temperature drift compensation without TCXO via AFC, using a 4.9152–19.6608 MHz parallel-resonant crystal.
Transmit path includes a fully integrated PA with programmable output power (–20 to +10 dBm at 433 MHz), while digital interface uses 4-wire SPI (PCLK/PDI/PDO/PSEL) for register configuration. The device integrates ADC for RSSI, bit synchronizer for NRZ/Manchester data, and dual LNA/PA enable outputs (LNA_EN/PA_EN) for external gain control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar narrowband RF transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CC1120RHBR | Successor device with higher sensitivity (–129 dBm), wider frequency range (27–1050 MHz), and integrated DC-DC converter - requires different layout and register mapping. | Targets next-gen designs needing extended range or multi-band flexibility; not drop-in compatible due to pinout and power architecture changes. | Select CC1120RHBR for new designs requiring FCC/EN-compliant long-range telemetry; retain CC1020RUZ for legacy AMR hardware reuse. |
| SI4463-B1B-FMR | Sub-GHz transceiver with +20 dBm output power, integrated PA, and lower RX current (13.7 mA); supports same modulation schemes but different SPI timing and register set. | Better suited for battery-constrained nodes needing higher TX range; lacks native AFC for crystal drift compensation without external circuitry. | Choose SI4463-B1B-FMR when output power >+10 dBm is mandatory; verify crystal stability requirements match its fixed AFC implementation. |
Compared with CC1120RHBR and SI4463-B1B-FMR, the CC1020RUZ offers proven narrowband performance in legacy 433/868 MHz AMR deployments with minimal external components, while trading raw sensitivity and output power for mature design-in confidence and lower system-level complexity.

FAQ
What is the maximum data rate supported by the CC1020RUZ?
The CC1020RUZ supports a maximum data rate of 153.6 kBaud in NRZ mode (equivalent to 153.6 kbps), or 76.8 kbps in Manchester mode. This capability is confirmed in Section 4.4 of the SWRS046H datasheet and applies across its operational frequency bands (402–470 MHz and 804–960 MHz). The CC1020RUZ achieves this using its integrated bit synchronizer and digital modulator, with actual throughput dependent on encoding scheme and channel spacing.
Does the CC1020RUZ require an external TCXO for stable operation?
No, the CC1020RUZ does not require an external TCXO. It implements an integrated AFC (Automatic Frequency Control) function that compensates for crystal oscillator temperature drift using the internal PLL - enabling stable operation across –40°C to +85°C without TCXO. This is explicitly stated in the "Features" section and detailed in Section 5.9.3 of the SWRS046H datasheet for the CC1020RUZ.
What package type and dimensions does the CC1020RUZ use?
The CC1020RUZ uses a VQFNP (Very Thin Quad Flat No-Lead Package) with 32 pins and nominal body size of 7.00 mm × 7.00 mm. This QFN-32 package includes an exposed die-attach pad that must be soldered to a solid ground plane, as specified in Table 1-1 and Section 8 of the SWRS046H datasheet for the CC1020RUZ.
Which regulatory standards does the CC1020RUZ support out of the box?
The CC1020RUZ is designed to support compliance with EN 300 220 (Europe), FCC CFR47 Part 15 (USA), ARIB STD-T67 (Japan), and ARIB STD-T96 (Japan) when used with appropriate matching networks and filtering per TI's reference design CC1020EMX. Its sensitivity, spurious emission, and adjacent-channel rejection specs are validated against these standards in the SWRS046H datasheet for the CC1020RUZ.
Can the CC1020RUZ operate in both OOK and FSK modulation modes?
Yes, the CC1020RUZ natively supports OOK, FSK, and GFSK modulation schemes as stated in its "Features" list and verified in Sections 4.4 (Transmit) and 4.5 (Receive) of the SWRS046H datasheet. Minimum OOK data rate is 2.4 kBaud in the 402–470 MHz band, and FSK separation is programmable up to 108 kHz (402–470 MHz) or 216 kHz (804–960 MHz) for the CC1020RUZ.
