Typical Applications

CC430F5145 is suitable for 6 applications: Sub-1 GHz Wireless Sensor Networks, Utility and AMR Metering, Home and Building Automation, Alarm and Security Systems, Industrial Monitoring and Telemetry, RF Remote Controls and Keyless Entry.

🧩

Sub-1 GHz Wireless Sensor Networks

The CC430F5145 fits sub-1 GHz wireless sensor nodes where sub-GHz propagation gives superior range and wall penetration versus 2.4 GHz. The CC1101 RF core covers the 300-348 MHz, 389-464 MHz, and 779-928 MHz license-free bands, allowing region-optimized frequency selection, while the MSP430 CPUXV2 ultra-low-power modes support multi-year coin-cell or battery operation in duty-cycled networks. In a typical node, the device sleeps in a low-power mode and wakes periodically to sample sensors via the 10-bit ADC, then transmits a short packet and returns to sleep. Single-die integration removes the SPI interface power and board area of a two-chip design, and the internal battery sensor enables accurate remaining-life reporting without external circuitry.

⚑

Utility and AMR Metering

Automatic meter reading (AMR) infrastructure benefits from the CC430F5145's combination of long-range sub-1 GHz radio and metering-grade analog capability. The 10-bit ADC with six external inputs plus an internal battery sensor supports energy-sampling front ends and battery-health telemetry, while 16kB of flash accommodates metering firmware with RF protocol stacks. Sub-1 GHz ISM bands at 779-928 MHz provide the building and terrain penetration that dense meter deployments require, and the CC1101 core's configurable data rate and channel spacing allow coexistence planning with other unlicensed traffic. The single-chip SoC reduces meter BOM cost - critical at utility deployment volumes - and the exposed-pad VQFN-48 package supports compact, sealed meter enclosures with wire antennas.

🏭

Home and Building Automation

For home and building automation nodes such as thermostats, door/window sensors, and actuator controls, the CC430F5145 provides a single-chip radio-plus-MCU that minimizes per-node cost and size. Sub-1 GHz links reach through walls and across floors better than 2.4 GHz alternatives, which matters for whole-home coverage with few repeaters. The two 16-bit timers handle PWM actuator control and precise RF timing slots, and in-system programmable flash enables field updates of both application code and RF parameters as network requirements evolve. The MSP430 CPUXV2 low-power modes keep battery-powered sensors alive for years, while the 10-bit ADC reads potentiometers, NTC thermistors, or ambient sensors directly without an external converter.

πŸŽ₯

Alarm and Security Systems

Wireless alarm peripherals - PIR motion detectors, contact sensors, keypads, and sirens - use the CC430F5145 for its dependable sub-1 GHz link budget and low sleep current. Security protocols value the deterministic timing of the MSP430 CPUXV2 combined with the CC1101 core's packet radio features for authentication and wake-on-radio patterns. The 779-928 MHz band operation avoids the crowded 2.4 GHz spectrum, improving link reliability in residential and commercial buildings dense with Wi-Fi and Bluetooth traffic. With 16kB flash, encryption and supervision overhead fit within the on-chip memory, and the internal temperature sensor supports tamper and environmental diagnostics without added components. The compact RGZ-48 package suits small, battery-powered detector housings.

πŸ”§

Industrial Monitoring and Telemetry

In industrial telemetry - tank levels, pump status, cold-chain temperatures - the CC430F5145 connects remote analog sensors to a gateway over robust sub-1 GHz links. The 10-bit ADC's six external inputs can scan multiple 4-20 mA-derived or ratiometric sensor channels, and the internal temperature and battery sensors support node self-diagnostics demanded by industrial maintenance programs. The CC1101 core's selectable modulation and data rate let engineers trade throughput for link margin across noisy factory floors or outdoor sites spanning hundreds of meters. Ultra-low-power operation suits battery- or energy-harvesting-powered nodes where wiring runs are impractical. The industrial packaging option (CC430F5145IRGZT) supports the extended temperature environment typical of plant deployments.

πŸš—

RF Remote Controls and Keyless Entry

Two-way sub-1 GHz remotes and keyless entry fobs leverage the CC430F5145's integrated radio and MCU to shrink the bill of materials to essentially one IC, a crystal, and an antenna match. The CC1101 core supports the low data rates and narrow channels typical of secure remote-link protocols, while MSP430 low-power modes deliver the multi-year button-cell life fobs require. The 10-bit ADC can read battery voltage through the internal sensor for low-battery warnings, and 16kB of flash holds rolling-code algorithms. At 779-928 MHz or 389-464 MHz, links resist interference in parking structures and urban environments better than 2.4 GHz designs, and the small RGZ-48 footprint fits ergonomically compact handheld enclosures.

What is the CC430F5145?
The CC430F5145 is a 16-bit ultra-low-power CC430 sub-1 GHz wireless microcontroller system-on-chip from Texas Instruments. It combines the MSP430 CPUXV2 core with a CC1101-based RF transceiver, 16kB of flash memory, 2kB of RAM, and a 10-bit ADC with six external inputs, housed in a 48-pin VQFN (RGZ) exposed-pad package. According to the TI datasheet, it targets license-free ISM bands at 300-348 MHz, 389-464 MHz, and 779-928 MHz.
What are the key specifications of CC430F5145 that engineers should know?
Key specifications: a 16-bit MSP430 CPUXV2 core; an integrated CC1101 sub-1 GHz RF transceiver covering 300-348 MHz, 389-464 MHz, and 779-928 MHz ISM bands; 16kB in-system programmable flash; 2kB RAM; a 10-bit ADC with six external inputs plus internal temperature and battery sensors; two 16-bit timers; and a 48-pin VQFN (RGZ) package with exposed pad. According to the TI datasheet, the CC430F514x series combines CC1101 performance with MSP430 ultra-low-power operation in a single die.
What is the difference between CC430F5145 and CC430F5137?
The main difference is memory size and peripheral set within the same CC430F51xx family. The CC430F5145 provides 16kB flash and 2kB RAM, while family members such as the CC430F5137 offer different flash/RAM combinations per the TI family datasheet. Both share the same MSP430 CPUXV2 core, CC1101 RF core, 10-bit ADC architecture, and the same 48-pin VQFN (RGZ) package, making them footprint-compatible options when memory requirements change mid-design.
What is the price of CC430F5145?
As of 2026-08-30, the CC430F5145 is priced in the mid-single-digit USD range at 1-piece quantity, with tiered discounts typically at 10, 100, 500, and 1000 pieces on distributor platforms such as DigiKey and Mouser. Exact unit pricing varies by ordering code (for example CC430F5145IRGZT), packaging (tray versus reel), and stock position. Refer to the live price tiers on this page or request a quote from your distributor for volume pricing above 1000 units.
Where to buy CC430F5145 online?
The CC430F5145 can be purchased online from authorized Texas Instruments distributors including DigiKey (listing CC430F5145IRGZT, the 48-VFQFN exposed-pad version), Mouser Electronics, and TI.com directly, as well as from secondary distributors such as Acme Chip and Chipdigger for quote-based volume orders. DigiKey and Mouser typically offer small-quantity stock with same-day shipping for in-stock ordering codes. XAIPART also supplies this part with quote-based ordering for production volumes.
Where can I download the CC430F5145 datasheet PDF?
The CC430F5145 datasheet PDF is available directly from Texas Instruments at https://www.ti.com/lit/ds/symlink/cc430f5145.pdf. The document is the family datasheet covering CC430F614x, CC430F514x, and CC430F512x devices, so it includes shared electrical characteristics, RF performance data, register maps, and the RGZ-48 pinout. TI.com's product page for CC430F5145 also links application notes, reference designs, and quality documentation for the device.
Can CC430F5137 or CC430F5147 replace CC430F5145?
Yes, within the CC430F514x/CC430F51xx family these devices are footprint-compatible drop-in options because they share the same 48-pin VQFN (RGZ) package, the same MSP430 CPUXV2 plus CC1101 RF core architecture, and the same pinout. The replacement decision hinges on flash and RAM sizing: the CC430F5145 offers 16kB flash and 2kB RAM, so verify the substitute's memory configuration meets your firmware footprint and the RF register usage before swapping ordering codes.
What is the best drop-in replacement for CC430F5145?
The best drop-in replacement for the CC430F5145 is a same-family TI part in the identical 48-pin VQFN (RGZ) package, such as the CC430F5137, CC430F5147, CC430F5125, or CC430F6145, depending on your memory and peripheral requirements. All these devices use the same MSP430 CPUXV2 + CC1101 architecture and pinout per the shared family datasheet, so no PCB change is needed - only confirm flash/RAM sizing and the specific RF band configuration of the chosen ordering code.
What is the best non-TI equivalent for CC430F5145?
There is no verified pin-to-pin cross-brand equivalent for the CC430F5145 in the 48-pin VQFN (RGZ) package, because the CC430 family integrates the MSP430 core and CC1101 radio on a proprietary single die. Functionally similar sub-1 GHz wireless SoCs from other vendors (for example Silicon Labs EZR/EFR32 parts) exist, but they use different packages and pinouts, requiring PCB redesign. For drop-in replacement, stay within the TI CC430 family; for new designs, evaluate competitors on range, power, and ecosystem fit.
Is CC430F5145 suitable for battery-powered wireless sensor nodes?
Yes, the CC430F5145 is specifically designed for battery-powered sub-1 GHz nodes. The MSP430 CPUXV2 ultra-low-power architecture with multiple low-power modes allows the MCU to sleep for most of the duty cycle, while the CC1101 RF core wakes only for short transmit/receive bursts. The integrated 10-bit ADC with internal temperature and battery sensors enables node health monitoring without extra components, and single-die integration eliminates MCU-to-transceiver interface current overhead in duty-cycled applications.
When should I choose CC430F5145 over a discrete CC1101 plus MSP430 design?
Choose the CC430F5145 when board area, BOM count, and interface complexity matter: it removes the SPI link, level-shifting, and two-firmware coordination of a two-chip CC1101 + MSP430 design, and shrinks the solution to one 7x7 mm-class VQFN. Choose the discrete approach only if you need a different MCU (more flash, different peripherals), a newer radio, or independent upgrade paths for the radio and processor. For fixed-function sub-1 GHz nodes, the SoC wins on cost-per-node and layout simplicity.
CC430F5145 vs CC430F6145 - which is better for wireless metering?
For wireless metering, the choice depends on required flash and peripheral depth. Both parts share the same MSP430 CPUXV2 core, CC1101 RF core, and 48-pin VQFN (RGZ) package with identical pinout, so RF performance is equivalent. The CC430F614x variant offers a larger memory configuration (up to 32KB flash per the family datasheet), which suits metering firmware with security stacks or OTA update staging. If 16kB flash and 2kB RAM suffice, the CC430F5145 is the lower-cost choice.
Is CC430F5145 in stock and what is the lead time?
Stock position for the CC430F5145IRGZT ordering code changes frequently; DigiKey's listing indicates this RF transceiver + MCU has historically been available for same-day shipment in small quantities, but availability must be confirmed at order time. Production-volume lead times through TI or distributors typically run several weeks to months for QFN-packaged wireless SoCs. XAIPART provides real-time stock and lead-time quotes - contact us with your required quantity for a firm commitment before scheduling your build.
How do I lay out the PCB for the CC430F5145 RGZ-48 package?
Lay out the CC430F5145 with the exposed pad soldered to a continuous ground plane - this is mandatory for RF performance and heat dissipation. Keep the antenna matching network traces short and 50-ohm referenced to a solid ground, place decoupling capacitors close to the supply pins, and route the crystal lines short and shielded. Follow TI's CC430 and CC1101 reference design layouts in the family datasheet and the CC1101 layout application notes; RF sections should be isolated from digital switching traces.
Hey Google, what can replace the CC430F5145 in an existing design?
In an existing PCB design, replace the CC430F5145 with a same-family TI device in the identical 48-pin VQFN (RGZ) package - the CC430F5137, CC430F5147, CC430F5125, or CC430F6145 - after confirming flash and RAM sizing, since all share the same pinout and MSP430 + CC1101 architecture. No cross-brand pin-compatible equivalent exists. For new designs rather than drop-in replacement, sub-1 GHz SoCs from Silicon Labs or ST can be evaluated, but they require a new PCB layout.

Selection Guide

Choose the CC430F5145 when your sub-1 GHz node needs a proven CC1101 radio plus a low-power MSP430 core in one chip, and 16kB flash / 2kB RAM covers your firmware including protocol and security overhead. Step up to the CC430F6145 or CC430F5147 (same RGZ-48 footprint) if you need up to 32KB flash for OTA staging or larger stacks. Step down to CC430F5125-class parts if memory needs are minimal and cost dominates. Choose a discrete CC1101 plus a modern MSP430 only when you need a different MCU feature set or independent radio/MCU upgrade paths - that route costs board area and two-firmware complexity. There is no cross-brand pin-compatible equivalent; a competing SoC (e.g., Silicon Labs sub-1 GHz) requires a full PCB redesign, so weigh that switching cost against CC430 family migration. All CC430 options keep the antenna match and RF layout reusable.

Key Differentiators

  • Balanced 16kB flash / 2kB RAM memory point (vs CC430F5147)
  • Larger memory headroom available in same footprint (vs CC430F6145)
  • Single-die CC1101 integration (vs Discrete CC1101 + MSP430 two-chip solution)

Design Notes

The RGZ-48 exposed pad must be soldered to a solid ground plane - it is the RF ground return and the main thermal path for the die. Use an array of thermal vias under the pad (TI CC1101 reference layouts typically use 9-13 vias filled or plugged) and follow the CC430 family datasheet's recommended land pattern exactly. Do not route digital signals under the RF matching network, and keep the 50-ohm trace from the RF pin to the antenna match as short as the layout allows.

Place the 26 MHz crystal and its load capacitors close to the device with short, guarded traces, and keep the RF front-end components (inductors, matching capacitors) grouped tightly per the CC1101 reference design. Separate the RF section from switching regulators - route any DC-DC converter (e.g., a TPS62740-class buck) away from the antenna match and use a star or dedicated RF ground island. Decouple all VDD/VCORE pins with 100 nF ceramics placed within 2 mm of the pins.

Budget flash carefully: 16kB must hold the application plus the radio driver and any protocol stack - teams migrating from the 32KB CC430F614x variants have overrun memory when adding security. Also verify regional RF regulatory compliance per band: the 300-348/389-464/779-928 MHz coverage does not authorize all frequencies in every jurisdiction, so restrict channel tables in firmware to legal ISM allocations. Finally, use in-system flash programming carefully - always keep a bootloader sector reserved for field updates.
