Overview
The TRF6900PT is a single-chip RF transceiver from Texas Instruments, housed in a 48-lead LQFP package. It operates within the 850–950 MHz frequency range with a supply voltage of 2.2–3.6 V. The device delivers +5 dBm RF output power and supports FM/FSK modulation via a three-wire serial interface. It integrates a 16-bit RISC microcontroller running at up to 8 MIPS. Standby current consumption ranges from 0.5 μA to 5 μA. The internal architecture includes a PLL synthesizer, DDS, and low-noise amplifier.
Feature Summary
- Integrates complete transmit and receive circuits on a single chip
- Supports bidirectional wireless data transmission in ISM bands
- Features low-power standby mode for battery-operated systems
- Utilizes a high-throughput 16-bit RISC microcontroller core
Applications
- Computer telemetry and remote control systems
- Handheld battery-powered instrumentation equipment
- Security and alarm systems
Procurement Notes
Verify the specific suffix (PT) confirms the 48-LQFP package and commercial temperature grade. Confirm availability status as this component may be discontinued or subject to long lead times. Ensure the source document matches the exact part number to avoid confusion with similar variants like TRF6900APTR.
Selection Notes
Select this component for applications requiring integrated RF functionality without external mixers or oscillators. It is suitable for designs needing moderate output power and low standby current. Verify that the required operating frequency falls within the 850–950 MHz range. Ensure the host microcontroller can interface with the three-wire serial protocol.
Part Context
This part belongs to the TRF6900 family of single-chip RF transceivers designed for short-range wireless communication. It is distinct from higher-frequency variants such as the 2.4 GHz models. The device combines analog RF front-end capabilities with digital control logic, simplifying system design for industrial and consumer applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult Texas Instruments for current equivalent recommendations or updated product line information.
