CC1100ERGPT Descripción general
An RF transceiver is an integrated circuit that combines a radio transmitter and receiver on a single chip, converting digital baseband data to modulated RF signals and back. Within the power management and connectivity hierarchy of a wireless system, the transceiver sits between the microcontroller (its SPI host) and the antenna, handling modulation, demodulation, packet handling, and RF front-end functions that would otherwise require discrete circuitry.
Key features include support for 2-FSK, GFSK, MSK, ASK, and OOK modulation, a maximum data rate of 500 kBaud, and receive current of only 15.4 mA to 20 mA. The CC1100E was purpose-designed for the Chinese 470-510 MHz metering band and Japanese 950-960 MHz RFID band, making it the natural choice for regulatory-compliant designs in those markets.
Architecturally, the CC1100E is a true single-chip transceiver with an integrated low-IF receiver, fractional-N synthesizer, and power amplifier. According to TI, the CC1100E is code, package, and pinout compatible with the widely adopted CC1101 and CC1100, enabling design reuse across regional product variants. A standard SPI serial interface exposes configuration registers, FIFOs, and packet engine controls to any host MCU.
Typical applications include smart meters and utility metering in China, active RFID tags in the Japanese 950-960 MHz band, wireless sensor networks, home automation, and alarm and security systems operating under local sub-1GHz ISM/SRD regulations.
A key design consideration: RF matching network and antenna design must match the target band (470-510 MHz or 950-960 MHz), and reference designs from TI should be followed closely for crystal, balun, and decoupling layout to achieve the -112 dBm sensitivity rating.

Aplicaciones típicas
CC1100ERGPT es adecuado para 6 aplicacións: Smart Utility Metering, Active RFID in the Japanese 950-960 MHz Band, Wireless Sensor Networks, Home Automation and Building Control, Alarm and Security Systems, Two-Way Remote Controls and Keyless Entry.
Smart Utility Metering
The CC1100ERGPT was designed specifically for the Chinese 470-510 MHz utility metering band, making it a direct fit for water, gas, and electricity meter networks. Its 10 dBm output and -112 dBm sensitivity provide a link budget of roughly 122 dB, sufficient for meter-to-data-collector links across dense urban deployments. With receive current of only 15.4 mA to 20 mA plus low-power sleep modes, battery-powered meters achieve multi-year service life. The SPI interface connects directly to the metering MCU, and the integrated packet engine handles FIFOs, address filtering, and CRC in hardware, offloading the host processor. Designs must follow TI reference layouts for the matching network to realize rated sensitivity.

Active RFID in the Japanese 950-960 MHz Band
Japan's 950-960 MHz RFID allocation is a primary target band of the CC1100E, and the part's 10 dBm output power complies with the low-power tagging rules of that band. Active RFID tags benefit from the 15.4 mA to 20 mA receive current and fast startup from sleep via the SPI wake sequence, enabling long coin-cell life. The -112 dBm sensitivity extends read range in cluttered warehouse and retail environments. Because tag antennas are small and detuned by proximity to objects, following the TI reference balun design keeps performance robust. The GFSK mode at moderate data rates offers a good balance of range and tag inventory speed.

Wireless Sensor Networks
For sub-1GHz wireless sensor networks in China and Japan, the CC1100ERGPT offers the right combination of range, power, and regulatory fit. Its 500 kBaud maximum data rate supports burst telemetry, while narrow 2-FSK settings maximize link margin for nodes at the edge of coverage. Hardware packet handling (64-byte TX/RX FIFOs, packet length configuration, auto CRC) reduces MCU overhead in multi-node networks. Sleep-current operation and channel configuration registers enable frequency-hopping or multi-channel schemes to combat congestion in the 470-510 MHz metering band. Pinout compatibility with the CC1101 lets one hardware platform serve multiple regional SKUs with only a matching-network change.
Recomendado
Home Automation and Building Control
Sub-1GHz radios penetrate walls better than 2.4GHz, and the CC1100ERGPT's 470-510 MHz operation provides reliable in-building coverage for lighting control, door locks, and HVAC sensors in Chinese and Japanese markets. The OOK and ASK modes support very simple, low-cost one-way devices such as wall switches, while GFSK two-way links handle command-and-status traffic. Wake-on-radio functionality lets battery devices sleep at microamp levels and poll periodically. The 20-pin VQFN's 4x4 mm footprint fits compact wall-mounted form factors. Designers should validate antenna detuning in final enclosures, as plastic housings and metal back boxes shift the resonant frequency.

Alarm and Security Systems
Wireless alarm accessories - PIR sensors, door contacts, sirens, and keypads - benefit from the CC1100ERGPT's -112 dBm sensitivity, which preserves link margin through walls and building corners where marginal radios drop events. The radio's hardware address filtering and packet CRC reduce false triggers from RF noise in the 470-510 MHz band. Fast RX-to-TX turnaround supports time-synchronized event bursts, and ASK/OOK modes allow compatibility with legacy one-way sensor fleets. Receive current of 15.4 mA to 20 mA permits always-listening panel receivers on mains power, while battery accessories exploit sleep modes. TI reference designs provide proven layouts for high-reliability links.
Recomendado
Two-Way Remote Controls and Keyless Entry
Two-way key fobs and remote controls in Chinese and Japanese markets can use the CC1100ERGPT's combination of OOK/GFSK modes, 10 dBm output, and compact 4x4 mm VQFN package. Two-way protocols leverage the radio's quick settling synthesizer and packet engine to confirm commands (echo-back), improving perceived reliability versus one-way remotes. Wake-on-radio and low sleep current stretch CR2032 coin-cell life across thousands of actuations. The SPI interface pairs naturally with small MCUs in fob form factors. Designers should keep the antenna clear of the user's hand and verify range in free-space and hand-held conditions, as body loading reduces effective radiated power.

Notas de diseño
RF performance is only as good as the layout. Follow the TI CC1100E reference design exactly for the antenna matching network, balun (or differential antenna connection to RF_N/RF_P), crystal placement, and decoupling capacitors. Keep RF traces short, route them over a solid ground plane, and place 0402-size matching components within 2-3 mm of the RF pins. The exposed pad under the VQFN must be soldered to a grounded thermal via array - it is the main RF ground return, and skipping it degrades sensitivity and output power.
Do not assume CC1100E and CC1101 designs are interchangeable at the RF level. Although the devices are pin-compatible, their frequency plans differ: the CC1100ERGPT targets 470-510 MHz and 950-960 MHz, so its matching network values differ from 433/868/915 MHz CC1101 designs. Swapping the chip without retuning the match will lose several dB of link margin. Also verify crystal tolerance and loading capacitors - narrowband 2-FSK channels at 470-510 MHz leave little room for frequency error.
Estimated: at 10 dBm TX output the CC1100E-class radio draws roughly 30 mA from a 3.0-3.3 V supply, so budget the DC-DC or LDO for at least 35-40 mA peak including MCU transmit overhead. Receive current is 15.4-20 mA. For battery nodes, place the radio in sleep between events and use wake-on-radio polling; average current, not peak current, determines battery life. Decouple AVDD and DVDD pins individually with 100 nF ceramics placed close to each pin per the datasheet layout.
