Overview
The TRF6900APTR is a single-chip RF transceiver from Texas Instruments designed for ISM band applications below 1 GHz. It operates within the 850 MHz to 950 MHz frequency range and supports FM/FSK modulation modes. The device integrates complete transmit and receive circuits, including an RF power amplifier capable of +5 dBm output. It features a high-throughput 16-bit RISC microcontroller with speeds up to 8 MIPS. Power supply requirements are between 2.2 V and 3.6 V, with standby current consumption as low as 0.5 μA to 5 μA. The component utilizes a three-wire serial interface for communication with microcontrollers.
Feature Summary
- Integrates complete transmit and receive circuitry on a single chip
- Supports FM and FSK modulation for data transmission
- Includes a high-performance 16-bit RISC microcontroller core
- Features low standby current consumption for battery-powered systems
Applications
- Computer telemetry and remote control systems
- Handheld battery-operated operating systems
- Instrumentation equipment
- Security and alarm systems
Procurement Notes
Verify that the specific suffix 'PTR' corresponds to the tape-and-reel packaging variant when sourcing components. Confirm that the device meets the required ISM band regulations for your target region. Ensure compatibility with the host microcontroller's voltage levels and serial interface timing specifications before integration into the final design.
Selection Notes
Select this component for applications requiring integrated RF and baseband processing in the sub-1 GHz range. It is suitable for designs needing moderate data rates and low power consumption. Consider the 48-pin LQFP package constraints for PCB layout. Evaluate the need for external passive components for the PLL loop filter and reference oscillator during the hardware design phase.
Part Context
The TRF6900 series represents a class of single-chip radios intended for wireless sensor network and general ISM band communications. It competes with other single-chip solutions by combining RF functionality with a built-in microcontroller. This integration reduces board space and simplifies system architecture compared to discrete RF front-end designs.
Replacement Considerations
Public confirmed substitute part numbers include TRF6900APT and TRF6900APTG4. These variants share the same functional description and package type but may differ in shipping configuration or compliance markings.
