BLUENRG-M0L - Bluetooth v4.2 LE Module 2.4GHz | STMicroelectronics
The STMicroelectronics BLUENRG-M0L is a Bluetooth v4.2 compliant, very low-power network processor module that operates in the 2.4 GHz to 2.4835 GHz ISM band. It is a surface-mount integrated chip antenna module that combines an embedded Bluetooth low-energy protocol stack with master/slave role support and simultaneous multiple-role operation, enabling concurrent sensor and hub functions on the same module. A Bluetooth Low Energy (BLE) module is a certified sub-system that bundles the radio transceiver, baseband, protocol firmware, and often an integrated antenna into a single reflow-solderable package. Within the wireless connectivity hierarchy, BLE modules sit below bare SoCs and above discrete 2.4 GHz radios: they trade flexibility for faster time-to-market because the wireless regulatory certification and stack integration are already completed by the module vendor. The BlueNRG-M0 family targets ultra-low-power IoT nodes where battery life, footprint and BOM count matter more than raw compute. Key features include Bluetooth v4.2 master/slave support, multi-role operation, an integrated chip antenna, surface-mount packaging in an 11-SMD module form factor, and an output power of 6 dBm. The BLUENRG-M0L variant differs from the BLUENRG-M0 in its regulatory certifications and is built around the BlueNRG-MS silicon. Sensitivity is rated at -85 dBm, receive current is 16.36 mA, and transmit current is 13.25 mA to 27.35 mA depending on output power setting. Architecturally, the BLUENRG-M0L is built around a low-power Cortex-M0 core running ST's embedded Bluetooth low-energy stack. The integrated chip antenna, RF matching network, crystals, and passive components are pre-tuned inside the module, so the host MCU only communicates with it over a UART/SPI host interface. This removes the need for 50-ohm RF layout expertise and saves several weeks of PCB iteration. Typical applications include BLE sensor nodes, beacons, smart-home hubs, fitness and medical wearables, industrial telemetry, and remote controls. The -40C to +85C operating range makes it usable in outdoor and industrial deployments. Because the regulatory certification is pre-done, designers can skip the FCC/CE/IC RF certification cycle and ship products faster. When designing with the BLUENRG-M0L, leave the antenna keep-out area clear of copper on all PCB layers and avoid placing metal components or shields above the antenna. Provide a stable 1.7 V to 3.6 V supply and place a 1 uF decoupling capacitor close to the module's VDD pin. The host MCU must drive the module via the documented ACI (Application Command Interface) over SPI or UART; firmware updates go through the bootloader. This page synthesizes distributor pricing, package-level drop-in variants, and practical design notes for fast time-to-market BLE designs that go beyond what the ST datasheet flyer alone provides.

The module supports industrial operating temperature range of -40C to +85C. A Bluetooth Low Energy (BLE) module is a type of short-range RF module that integrates a Bluetooth radio, baseband controller, and protocol stack into a single shielded unit. Within the wireless hierarchy, it sits between discrete RF transceiver chips and fully qualified end products, allowing OEMs to skip costly Bluetooth SIG qualification and RF tuning. BLE, also called Bluetooth Smart, is the low-power variant of the Bluetooth 802.15.1 standard optimized for battery-powered devices. Key features of the BM71 family include Bluetooth 5.0 compliance delivering up to 2.5x throughput improvement over Bluetooth 4.1 based designs, more secure connections, an on-board chip antenna requiring no external RF matching, and full shielding for coexistence with other radios. The embedded firmware implements the complete BLE stack, so the host MCU only needs a simple UART interface. Technically, the BM71 uses Microchip's certified radio with an embedded protocol stack, offloading advertising, connection management, GATT services, and security pairing from the host processor. Configuration is performed via simple ASCII or transparent UART commands, reducing firmware complexity and certification burden. Typical applications include IoT sensor nodes, smart home devices, battery-powered beacons, industrial wireless sensors, and connected medical accessories, where the module's low power sleep modes and small 9 x 11.5 mm footprint fit space- and energy-constrained designs. Design consideration: keep the module antenna region clear of ground planes and metal per Microchip's layout guidelines, and power the module from a clean 3.3V rail with local decoupling. This page synthesizes distributor availability, same-family drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
BM71BLES1FC2-0B02AA - BLE 5.0 Module 9x11.5mm | Microchip
The Microchip Technology BM71BLES1FC2-0B02AA is a fully certified Bluetooth 5.0 Low Energy (BLE) transceiver module operating in the 2.4 GHz ISM band, housed in a shielded 9 x 11.5 x 2.1 mm surface-mount package with an integrated chip antenna and -90 dBm receiver sensitivity. A Bluetooth Low Energy module is a complete wireless subsystem that integrates a BLE radio, baseband, protocol stack, and antenna into a single certified unit. In the system hierarchy it sits above discrete RF ICs (which require external stack development and RF design) and below complete host systems, functioning as a serial-to-BLE bridge that frees the host MCU from managing the Bluetooth software stack, timing-critical RF firmware, and regulatory certification. Key features of the BM71BLES1FC2-0B02AA include Bluetooth Core 5.0 compliance with up to 2.5x throughput improvement over earlier BM70-generation silicon, a completely integrated Bluetooth software stack with configuration via simple ASCII commands over UART, a shielded enclosure for EMI reduction, and an integrated chip antenna on a regulatory-certified variant. Supply voltage spans 1.9 V to 3.6 V, suiting single-cell lithium and 3.3 V logic designs, and the module is rated for industrial temperature environments. Architecturally, the BM71 embeds Microchip's BLE silicon with flash memory for stack and application script storage. The certified, shielded, antenna-integrated construction means the RF matching network, crystal, and antenna have been tuned by Microchip, removing the most error-prone portion of a wireless design. Developers interact with the module as a wireline replacement: UART data in, BLE data out. Typical applications include smart-home sensors and actuators, battery-powered IoT beacons, industrial wireless configuration and diagnostic links, and connected health accessories. The industrial temperature rating and shielded package also suit networked lighting controls and commercial building automation. A key design consideration is layout: although the antenna is integrated, keep at least the datasheet-recommended keep-out area free of copper and plastics above the antenna region to preserve the certified radiation pattern and sensitivity.

BM83SM1-00AB Bluetooth 5.0 Stereo Audio Module | Microchip
The Microchip Technology BM83SM1-00AB is a Bluetooth 5.0 stereo-audio transceiver module operating from 2.402 GHz to 2.48 GHz in a PCB-trace, surface-mount package. It supports Bluetooth Classic BR/EDR and Bluetooth Low Energy, together with HFP 1.7, HSP 1.2, A2DP 1.3, SPP 1.2, AVRCP 1.6, PBAP 1.2, GATT, and GAP. The module can receive audio through Auxiliary Input or I2S and stream it to as many as two paired Bluetooth sink devices using Audio Transceiver firmware. A Bluetooth audio module combines a short-range radio, baseband protocol stack, audio interface, and embedded control functions in one surface-mount assembly. The BM83 belongs to the RF transceiver-module hierarchy rather than a discrete Bluetooth IC: designers connect the module to a host product through power, control, communication, and audio interfaces instead of implementing an RF antenna network and Bluetooth firmware from scratch. Its Class 1 designation identifies it as a Bluetooth audio module intended for conventional short-range wireless audio links. The BM83SM1-00Tx configuration provides A2DP source capability, allowing legacy audio equipment to become a Bluetooth transmitter. A2DP Source and Sink support supports product designs that transmit or receive stereo audio. HSP 1.2 supports legacy headset roles, while HFP 1.7, PBAP 1.2, AVRCP 1.6, and SPP 1.2 address hands-free calling, phone-book access, media control, and serial data services. AAC and SBC decoding further broadens compatibility with common Bluetooth audio sources. The module integrates the radio and protocol functions required for embedded Bluetooth connectivity, reducing RF-layout exposure at the product level. Nevertheless, an embedded module does not eliminate antenna-design requirements: the PCB, copper, enclosure, ground distribution, and matching network still determine practical RF performance. Firmware selection and host-interface integration are equally important because protocol support alone does not establish the final user experience. Typical uses include Bluetooth audio dongles, wireless speakers, headphones, soundbars, automotive-accessory adapters, home-audio upgrades, and dual-sink speaker systems. Auxiliary Input suits products with an existing analog source, while I2S supports digital audio integration. The stated ability to stream to two paired sink devices is particularly useful when one product must share audio with two headphones or speakers. For implementation, follow the manufacturer datasheet for the exact 50-lead land pattern, exposed-pad or thermal requirements, supply sequencing, UART or control behavior, firmware configuration, and antenna clearance. Preserve the documented keep-out regions around the module and connect its RF reference and ground features exactly as specified. Do not assume that another BM83 suffix is interchangeable without checking revision, antenna, firmware, and regulatory differences.
BM83SM1-00TA Bluetooth 5.0 Stereo Audio Module | Microchip
The Microchip Technology BM83SM1-00TA is a Bluetooth 5.0 stereo audio module operating across 2.402 GHz to 2.48 GHz in a 50-lead surface-mount package. It combines Bluetooth Classic BR/EDR and Bluetooth Low Energy connectivity with integrated audio-transceiver firmware. According to the verified Microchip product material, the module supports HFP 1.7, HSP 1.2, A2DP 1.3, SPP 1.2, AVRCP 1.6, and PBAP 1.2, including A2DP source and sink operation. A Bluetooth audio module is a wireless connectivity and embedded-control subsystem that adds Bluetooth communication to an audio product without requiring a discrete radio design. In the broader product hierarchy, this module is a Bluetooth transceiver module, an RF and wireless module, and an embedded audio bridge. It can receive audio through auxiliary input or I2S and stream that audio to up to two paired Bluetooth sink devices, making it useful for dongle-style designs and products without native Bluetooth. The BM83SM1-00TA is qualified for Bluetooth 5.0 and supports Classic BR/EDR as well as BLE. Its profile set covers hands-free, headset, advanced audio distribution, serial port, audio/video remote control, and phone-book access functions. A2DP source and sink capability supports both sending audio to headphones or speakers and receiving audio from a paired source. The module also supports AAC and SBC decoding, broad protocol support, and GATT/GAP services. The BM83 family is intended for stereo-audio connectivity in compact embedded products. Its integrated module approach reduces the need to design and qualify a separate RF radio, antenna structure, audio interface, and Bluetooth protocol stack on the host PCB. Firmware configuration remains important: the BM83SM1-00Tx variant implements A2DP source capability using Audio Transceiver firmware, so host firmware and command sequences must match the intended audio role. Typical uses include Bluetooth audio dongles, wireless speakers, headphones, source accessories, home-audio adapters, and embedded audio gateways. The verified data confirms the frequency range, Bluetooth version, protocol profiles, audio inputs, and dual-sink streaming behavior. Electrical limits, pin names, supply voltage, antenna requirements, and package dimensions should be taken from the manufacturer datasheet before PCB release. PCB implementation must preserve the module’s required antenna clearance, ground connectivity, audio routing, and power decoupling. Keep RF-sensitive and audio-sensitive traces away from noisy switching paths where practical, provide the manufacturer-specified bypass capacitors close to the supply pins, and follow the reference layout for antenna and exposed grounding. Validate RF performance with the intended enclosure because plastic, cables, grounding, and nearby structures can change the installed antenna behavior. This product-data page combines the verified Microchip feature description, distributor identification, and cross-reference search results. It distinguishes confirmed facts from missing electrical details and avoids inventing a pinout or package drawing that was not present in the supplied sources. For production use, compare the selected BM83SM1 variant, firmware image, regulatory requirements, and supplier availability before committing the design.

Key features include full Bluetooth 5.0 long-range support, 802.15.4 Thread and Zigbee protocols, and an open CPU architecture that lets developers run their own firmware on the embedded nRF52840 with 1 MB flash and 256 KB RAM. The U.FL connector enables optimized external antennas for maximum range. The module is certified for use in Canada under ISED RSS-247 Issue 2 and RSS-Gen per the u-blox datasheet, and its footprint is identical to the BMD-340, with pins 1 through 47 directly mapping to BMD-300/301/330/360 for design reuse. Typical applications include low-power IoT sensor nodes, smart-home Thread/Zigbee devices, beacons, and connected industrial equipment. Design consideration: when one PCB design may use BMD-340, BMD-341, or BMD-345, follow the BMD-340 copper keep-out area for the trace antenna variant. This page synthesizes distributor pricing, pin-compatible drop-in alternatives, and design notes not found in the manufacturer datasheet.
BP35A1 - 920MHz Wi-SUN Module with 32-bit MCU | ROHM
The ROHM BP35A1 is a 920MHz specified low-power radio module certified for the Wi-SUN (Wireless Smart Utility Network) standard, integrating a 32-bit microcontroller, Wi-SUN B-route firmware, and a built-in antenna in a connector-joint-type package. Receiver sensitivity is -103dBm typical at 100kbps with BER below 0.1%, providing high communication quality for smart-meter and home-energy-management links. A Wi-SUN module is a radio-frequency transceiver module that implements the Wi-SUN mesh networking protocol stack, a wireless standard used widely in utility infrastructure such as smart electricity, gas, and water meters. Within the system hierarchy, the BP35A1 sits at the module level: it combines a sub-GHz RF transceiver, baseband, protocol firmware, and host microcontroller into a single certified unit, so designers do not need to develop RF circuitry or obtain radio certifications themselves. Key features include operation in the 920MHz band, integrated Wi-SUN B-route profile firmware, a built-in antenna that removes external antenna matching from the design, and a connector joint type interface that allows the module to be plugged into a host PCB rather than soldered, simplifying assembly and field replacement. The -103dBm sensitivity at 100kbps (BER < 0.1%) supports long-range, low-data-rate mesh links typical of HAN (Home Area Network) single-hop topologies. The module is Wi-SUN Alliance certified as product WSA0064 (HEMS Controller, HAN single-hop). Technically, the BP35A1 integrates the RF transceiver, a 32-bit microcontroller running the Wi-SUN stack, and regulatory-certified radio parameters in one module, per the ROHM featured-products documentation. This integration reduces RF design risk, eliminates RF layout iteration, and shortens time to certification for ECHONET-Lite-based smart meter systems. Typical applications include smart electric meter HAN communication (B-route), home energy management system (HEMS) controllers, building energy monitoring, and sub-GHz mesh sensor networks in the 920MHz band. A key design consideration: because the module uses a connector joint type interface, plan the host-side mating connector and keep-out zone early; ROHM offers the dedicated BP35A7A 2.54mm-pitch conversion adapter board for evaluation and prototyping. This page synthesizes distributor availability, drop-in alternative analysis, and practical design guidance not found in the manufacturer datasheet.
BP35C5 - Wi-SUN FAN Sub-GHz Transceiver Module | ROHM

A Wi-SUN (Wireless Smart Utility Network) module is a radio transceiver with an integrated 32-bit MCU that implements the Wi-SUN FAN (Field Area Network) mesh networking protocol, an international standard optimized for smart community and utility infrastructure. Wi-SUN FAN devices form self-healing mesh networks supporting frequency-hopping spread spectrum, making them a power-management-layer building block for large-scale IoT deployments such as smart meters and street lighting. Key features of the BP35C5 include a maximum data rate of 300 kbps, receiver sensitivity of -105 dBm for extended link budget, and UART and GPIO host interfaces that simplify integration into existing systems. The module is certified under both Wi-SUN and FCC (US) regulations, significantly reducing end-product certification effort and enabling immediate evaluation. Technically, the BP35C5 integrates a Sub-GHz RF transceiver and 32-bit microcontroller running the Wi-SUN FAN stack, exposing a command-based UART interface so host processors do not need to implement the mesh protocol themselves. This offloads protocol complexity, flash footprint, and RF layout challenges from the host design. Typical applications include smart electricity, gas, and water metering networks, street lighting control, and smart city infrastructure across North America (902-928 MHz ISM band). Design consideration: an antenna is not included; ensure a 50-ohm matched antenna connection and verify FCC modular-approval conditions for the final enclosure. This page synthesizes distributor pricing, availability, lifecycle status, and practical design notes not found in the manufacturer datasheet alone.
BR-100AH-US - 802.11ah Wi-Fi HaLow Ethernet Bridge | Silex
The Silex Technology BR-100AH-US is a 10/100 Ethernet-to-802.11ah (Wi-Fi HaLow) wireless bridge operating in the sub-1 GHz band at 926.5 MHz (US SKU), delivering over 1 Mbps throughput in a standalone boxed enclosure with one RJ-45 Fast Ethernet port. An Ethernet-to-wireless bridge is a networking device that connects any Ethernet-equipped equipment to a wireless network by transparently converting wired frames to radio frames. In the network hierarchy it sits at the edge of the wireless LAN as a wireless client (station) with an embedded wired switch port, allowing legacy devices without native Wi-Fi to join a WLAN without driver or application changes. Key features include support for IEEE 802.11ah, the long-range, low-power Wi-Fi HaLow standard that operates below 1 GHz for dramatically better wall penetration and range than 2.4 GHz or 5 GHz Wi-Fi; software-transparent operation requiring no changes to drivers, management tools, or applications; multi-client mode operation; and a simple 10/100 Ethernet interface that makes integration plug-and-play. The 802.11ah radio in the 920-928 MHz unlicensed band trades raw bandwidth for range and link robustness, making it well suited for machine-type traffic at megabit-class data rates. Because the BR-100AH-US presents itself as a standard network device, industrial controllers, printers, cameras, and medical instruments can be relocated anywhere in a facility with wireless coverage. Typical applications include factory automation and industrial IoT sensor networks, smart building and metering infrastructure, and medical device connectivity where long range and wall penetration matter more than gigabit speeds. Design consideration: place the bridge within verified HaLow access point coverage and confirm regional regulatory fit - the US SKU (926.5 MHz) must not be deployed in regions using different 802.11ah channel plans such as China or Europe. This page synthesizes distributor availability, regulatory SKU information, and practical deployment notes not consolidated in the manufacturer datasheet.

The Cisco C9400-SUP-1XL-Y is a next-generation supervisor engine for the Catalyst 9400 Series modular chassis, designed for enterprise-class core and aggregation deployments and delivering up to 240 Gbps per slot with native 25G uplink connectivity. The -1XL-Y variant adds a 25 Gigabit Ethernet uplink option to the proven Supervisor-1XL platform, providing investment protection as enterprises migrate from 10G aggregation to 25G core links. It is built around the Cisco UADP 2.0 ASIC with a programmable pipeline, microengine capabilities, and template-based allocation of Layer 2/3, forwarding, QoS, and ACL resources, ready for next-generation enterprise and SD-Access services including MPLS, VRF-aware Locator/ID Separation Protocol, and host-tracking database features. The supervisor occupies the dedicated supervisor slot in the Catalyst 9404R, 9407R, and 9410R chassis (one active plus one redundant SSO supervisor), and ships with 240 GB of SSD storage by default for IOS XE image, packages, and telemetry buffers. Two SFP28 uplink ports provide the 25G migration path while QSFP ports (numbered 9 and 10 on this -1XL-Y SKU) support 40G operations via QSFP transceivers with LC, copper, or MPO-12 connectors. A supervisor engine in a modular access/aggregation chassis is the centralized control plane and switching fabric manager: it runs the routing protocol stack, manages the line-card forwarding ASICs, terminates management access, and houses the bootflash, DRAM, and SSD that host Cisco IOS XE. Within Cisco's modular hierarchy, the C9400-SUP-1XL-Y sits between the entry-level C9400-SUP-1 (80 Gbps/slot, 1/10/40G uplinks) and the flagship C9400X-SUP-2/2XL (480 Gbps/slot, 100G uplinks, UADP 3.0sec), offering a balanced 240 Gbps/slot middle ground for buyers who need 25G uplinks today but do not yet require 100G or UADP 3.0sec scale. Key features include 240 Gbps per-slot switching capacity, dual SFP28 25G uplinks, dual QSFP 40G uplink ports (ports 9-10), SSD-backed storage, Stateful Switchover (SSO) for hitless failover, advanced routing (MPLS, BGP, OSPF, EIGRP, IS-IS), SD-Access border node capability, and full IOS XE programmability via Guest Shell, Python, and NETCONF/YANG APIs. The C9400-SUP-1XL-Y uses the UADP 2.0 ASIC combined with a multi-core x86 CPU complex and hardware-accelerated cryptography. Compared with the original C9400-SUP-1, the -1XL variant triples per-slot bandwidth from 80 Gbps to 240 Gbps, enabling full 10G line-card oversubscription-free operation and paving the way for mGig/25G access tiers. Typical applications include enterprise core switching for campus and branch aggregation, MPLS-aware SD-Access border or collapsed-core nodes, 25G server-farm aggregation in mid-sized data centers, and high-availability dual-supervisor deployments in the Catalyst 9404R, 9407R, and 9410R modular chassis. When designing around the C9400-SUP-1XL-Y, plan for two supervisor slots per chassis, populate redundant SSO supervisor pairs for hitless failover, and pair the supervisor with line cards that do not require the higher-bandwidth C9400X-SUP-2/2XL (some newer C9400 line cards are restricted to the X-series supervisors only, so verify compatibility per the line card matrix). This page aggregates verified distributor specifications, drop-in supervisor alternatives in the same Catalyst 9400 family, and practical design notes not consolidated in the Cisco datasheet.

A narrowband RF transceiver is a radio IC that transmits and receives data over narrow frequency channels, typically 12.5 kHz or 25 kHz wide, as used in licensed and ISM/SRD (Short Range Device) bands. Within the radio hierarchy it sits at the physical layer: below the microcontroller that supervises it, alongside the antenna matching network, and above the baseband configuration registers programmed through its serial interface. Key features include 153.6 kBaud maximum data rate, programmable channel spacing and data filtering, and low receive-mode current consumption of 19.9 mA. The general ISM <1 GHz family classification covers popular bands such as 433 MHz, 868 MHz and 915 MHz used across industrial, scientific and medical (ISM) and short-range-device regulatory domains. Technically, the CC1020 integrates a complete transmit and receive chain on a CMOS process: low-IF receiver architecture with RSSI, frequency synthesizer with fractional-N PLL, and power amplifier for up to +10 dBm. Configuration is performed via SPI-compatible 3-wire or UART serial programming, giving the host MCU flexible control of frequency, modulation, and packet handling. Typical applications include narrowband telemetry in the 402-470 MHz band, wireless metering, alarm and security systems, and 868/915 MHz industrial short-range links where narrow channels give superior range and coexistence compared to wideband solutions. A key design consideration is RF board layout: the exposed pad must be soldered to a solid ground plane, and the VCO inductor and loop-filter components must follow the reference design layout to keep phase noise and spurious emissions within regulatory masks. This page synthesizes distributor pricing, drop-in alternatives including the TI CC1020RUZR alternate part number, and practical design notes not found in the manufacturer datasheet.
CC1020RSST - FSK/OOK UHF Transceiver 402-940MHz | TI
The Texas Instruments CC1020RSST is a true single-chip FSK/OOK CMOS UHF RF transceiver for narrowband systems, operating in the 402 MHz to 470 MHz and 804 MHz to 960 MHz bands, housed in a 32-pin VQFN package with exposed pad. It is designed for very low-power and very low-voltage wireless applications. A narrowband RF transceiver is a radio IC that transmits and receives data on channels only a few tens of kilohertz wide, sitting within the broader hierarchy of wireless connectivity ICs: RF transceiver -> RF integrated circuit -> semiconductor. Narrowband operation gives superior range and channel density versus wideband systems, making it the technology of choice for licensed and ISM/SRD telemetry links. Key features include fully integrated frequency synthesizer and transceiver chain for the ISM (Industrial, Scientific, and Medical) and SRD (Short Range Device) bands at 402, 424, 426, 429, 433, 447, 449, 469, 868, and 915 MHz, programmable multichannel operation at other frequencies within the supported bands, FSK and OOK modulation, and a CMOS process that keeps power consumption low for battery-operated nodes. Technically, the CC1020 integrates a low-IF receiver architecture and a direct VCO-based transmitter with an on-chip PLL synthesizer. Configuration of frequency, modulation, data rate, and power output is performed through a serial configuration interface from an external microcontroller, giving designers fine-grained control over the RF link. Typical applications include narrowband telemetry and metering links in the 433 MHz and 868/915 MHz ISM bands, 402-470 MHz utility and alarm systems, and short-range device communication in industrial and building-automation equipment. When designing with the CC1020RSST, follow the reference layout of the CC1020EM evaluation module, place matching-network components close to the antenna pins, and budget crystal tolerance carefully because narrowband channels leave little margin for frequency error. This page synthesizes distributor availability data, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
CC1021RSSR - Narrowband FSK/OOK UHF Transceiver | TI
The Texas Instruments CC1021RSSR is a true single-chip, low-power narrowband FSK/GFSK/OOK UHF RF transceiver operating in the 402 MHz to 470 MHz and 804 MHz to 960 MHz bands, supporting channel spacings of 50 kHz or higher, with a maximum data rate of 153.6 kBaud, packaged in a 32-pin VQFN (RSS) exposed-pad package rated from -40C to +85C. A narrowband RF transceiver is a radio IC that transmits and receives digitally modulated data over a shared radio channel using narrow channels (here 50 kHz or more), maximizing spectral efficiency in congested license-free ISM/SRD bands. Within the system hierarchy, the CC1021 sits at the physical layer of a wireless link: it is a half-duplex transceiver - containing both a transmitter chain and a superheterodyne-style receiver chain - that pairs with an external MCU which configures it and feeds it data through its serial interface. Key features include true single-chip integration (only the antenna matching network and crystal are external), multichannel operation with programmable channel spacing of 50 kHz or higher, three modulation schemes (FSK, GFSK, OOK), and very low power consumption aimed at battery-operated nodes. The supported data rate reaches 153.6 kBaud, sufficient for metering, alarm, and telemetry payloads. Output power is programmable, with -20 dBm listed among the supported output-power settings for short-range SRD compliance. Technically, the CC1021 is fabricated in CMOS and integrates the complete frequency synthesis, modulation, demodulation, and baseband filtering functions on one die. It targets the 433, 868, 915, and 960 MHz ISM/SRD bands, making it suitable for regulatory environments in Europe, North America, and Asia. According to the TI datasheet (document SWRS045C), the device is optimized for very low voltage, very low power wireless applications. Typical applications include Automatic Meter Reading (AMR) networks, wireless alarm and security systems, home automation, low-power telemetry, Remote Keyless Entry (RKE), Tire Pressure Monitoring Systems (TPMS), and general Short Range Device (SRD) links - all cases where narrowband channels and long battery life matter more than raw throughput. Design consideration: because channel spacing is narrow (50 kHz class), crystal accuracy and proper frequency planning dominate link reliability; budget for crystal tolerance and use the datasheet frequency-programming registers rather than assuming fixed-band defaults. This page synthesizes distributor availability data, datasheet-derived specifications, drop-in same-family alternatives, and practical design notes not found in the manufacturer datasheet, providing unique engineering value for sourcing and design decisions. Pricing and stock levels are quoted as of 2026-10-19 where available.

It is designed for multichannel operation with channel spacings of 50 kHz or higher, targeting the ISM and SRD bands at 433 MHz, 868 MHz, and 915 MHz. A narrowband RF transceiver is a wireless communication IC that transmits and receives data on very narrow radio channels, allowing many users to share spectrum with minimal interference. Within the RF system hierarchy (transceiver -> RF IC -> wireless semiconductor), the CC1021 integrates the complete transmit and receive signal path, requiring only a microcontroller, a crystal, and a small number of external passive components to form a complete radio link. Key features include true single-chip integration of a low-IF receiver and a direct VCO-based transmitter, programmable channel spacing from 50 kHz upward for licensed and unlicensed narrowband networks, and CMOS architecture optimized for very low power and very low voltage battery operation. The exposed-pad VQFN-32 package provides good RF grounding and thermal performance in a compact footprint. Technically, the CC1021 uses a CMOS RF architecture in which frequency synthesis, modulation, and demodulation are configured through an internal register set, allowing a host MCU to retune channels and data format on the fly. This flexibility makes it suitable for multichannel telemetry where frequency agility is required without hardware changes. Typical applications include narrowband telemetry in the 433 MHz, 868 MHz, and 915 MHz ISM/SRD bands, utility metering and alarm systems, and industrial remote control where low power consumption extends battery life. When designing with the CC1021RSST, budget board area for the external RF matching network and crystal circuit, and verify the programmed channel spacing against regional spectral regulations such as ETSI and FCC rules for the target market.

The device is designed for very low active and sleep-mode current consumption, making it well suited to battery-powered nodes. Architecturally, the CC1100E uses a low-IF receiver and a direct VCO/PA transmit chain with an integrated fractional-N synthesizer, which eliminates external SAW components in many designs. The baseband supports data rates and channel filtering bandwidths programmed through SPI registers, and two general-purpose data pins (GDO0/GDO2) provide packet/status signaling to the host MCU. Typical applications include wireless metering (electricity, water, gas), smart-home and security sensor networks, industrial telemetry, and remote-control links in the 470-510 MHz Chinese band and 950-960 MHz Japanese band. A key design consideration is RF board layout: the VQFN exposed pad must be soldered to a solid ground plane, and the RF matching network must follow the TI reference design for the target band.

The device integrates a fully programmable modem with multiple modulation formats including 2-FSK, 4-FSK, GFSK, MSK, OOK, and ASK, with configurable data rates from 0.6 to 600 kbps. A sub-1 GHz transceiver is a radio integrated circuit that transmits and receives digital data over industrial, scientific, and medical (ISM) frequency bands below 1 GHz. These bands are favored for low-power wireless links because they offer longer range and better wall penetration than 2.4 GHz alternatives at the expense of lower data rates. The CC1101 belongs to the broader family of wireless connectivity ICs alongside Wi-Fi, Bluetooth, and Zigbee transceivers, but occupies the niche of ultra-low-power, narrow-band, long-range sensor and command links. Key features include an integrated packet handler with 64-byte TX/RX FIFOs, CRC-16 hardware acceleration, whitening/de-whitening, address filtering, and AES-128 optional encryption via a coprocessor interface. Sensitivity reaches −110 dBm at 1.2 kbps (868 MHz), and output power is programmable up to +12 dBm. The SPI control interface operates from a separate digital supply, allowing the analog/RF section to remain active while the host MCU sleeps, achieving <200 nA sleep current. The CC1101 architecture combines a fractional-N PLL synthesizer, a low-IF receiver chain with programmable channel filter bandwidths, and an image-rejection mixer. The integrated PA ramp controller and AGC loops deliver robust performance across temperature, while a continuous frequency synthesizer allows frequency-hopping protocols to be implemented in firmware on the host controller. Typical applications include wireless sensor networks, smart metering (AMR/AMI), home and building automation, industrial monitoring, remote control systems, wireless alarm and security panels, and active RFID at 433/868/915 MHz. The wide tuning range also supports proprietary narrow-band protocols in medical telemetry and asset tracking. When designing with the CC1101, allocate sufficient PCB area for the differential RF output matching network and place the crystal reference as close to the chip as possible to avoid pulling. Use a four-layer stack with a continuous ground plane beneath the RF section and short, impedance-controlled traces to the antenna or BALUN.

The VQFN-20 (RGP) package with exposed pad provides compact 5x5 mm-class footprint with good RF grounding and thermal relief. Architecturally, the CC1101 integrates a low-IF receiver and a direct VCO-based transmit path on a single chip, with an on-chip crystal oscillator requiring only an external crystal. Configuration registers define frequency, channel spacing, modulation, data rate, and packet format, allowing one design to cover multiple regional frequency plans. Typical applications include 315/433/868/915 MHz ISM/SRD wireless sensor nodes, home and building automation, alarm and security systems, and industrial telemetry. Its programmable bands make it usable across regional regulatory domains with a single board design. When designing with the CC1101RGPRG4, follow the TI reference design layout closely: RF matching network component values depend strongly on the chosen frequency band, and the exposed pad must be soldered to a solid ground plane for RF performance.

Such transceivers are widely used for low-power wireless links where range, battery life and wall/obstacle penetration matter more than raw data rate. Key features of the CC110L include a highly configurable baseband supporting 2-FSK, GFSK and MSK modulation, a received-signal-strength indicator (RSSI) down to approximately -120 dBm sensitivity on LCSC product data, and a flexible packet engine with FIFOs for autonomous burst transmission. The device is driven by a standard SPI interface (SCLK, SI, SO, CSn) plus four configurable general-purpose digital output pins (GDO0, GDO1, GDO2) for packet status and clock output. Architecturally, the CC110L is a true single-chip transceiver: it integrates a low-IF receiver, fractional-N synthesizer, and power amplifier on one die, derived directly from the CC1101 silicon. This makes RF register configurations from the widely documented CC1101 ecosystem (SmartRF Studio, TI reference designs) directly applicable, dramatically shortening firmware development.
