MC33594FTAR2

RF Receivers Overview

The MC33594FTAR2 is a PLL-tuned UHF receiver designed for data transfer applications, manufactured by Freescale Semiconductor (NXP). It supports FSK and OOK modulation protocols across 315MHz and 434MHz bands. Key electrical parameters include a sensitivity of -105dBm at 4.8kBd, a typical run mode current of 5mA, and a supply voltage range of 1.9V to 3.6V. The device operates within a temperature range of -40°C to 85°C and features a maximum data rate of 11kBaud. It is housed in a 24-LQFP surface-mount package.

RF Receivers Feature Summary

• Fully integrated VCO with image cancelling mixer and internal IF bandpass filter at 660kHz.
• Configurable via SPI interface for ID byte detection, tone detection, and Manchester coded data clock recovery.
• Supports both internal and external strobing with fast wake-up time of 1ms.
• Requires few external components with no RF adjustment needed.

RF Receivers Applications

• General data transfer applications
• Wireless sensor networks
• Remote control systems

RF Receivers Procurement Notes

Verify component authenticity through authorized NXP or Freescale distributors due to the part's discontinued status. Confirm RoHS compliance requirements as the specific listing indicates non-compliance. Validate package integrity for the 24-LQFP form factor. Ensure design-in compatibility with existing SPI interfaces and power supply constraints before procurement.

RF Receivers Selection Notes

Select this component for low-power UHF reception requiring integrated frequency synthesis. It is suitable for designs needing minimal external passive components. Consider the discontinued status when planning long-term production runs. Evaluate thermal performance within the specified operating range for embedded environments.

RF Receivers Part Context

This receiver belongs to the MC335xx family of PLL-tuned UHF receivers from Freescale/NXP. It shares functional similarities with parts like the MC33591 and MC33592 but offers specific integration levels for data transfer. The family targets wireless communication applications requiring reliable demodulation of FSK and OOK signals.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The MC33591 and MC33592 are listed as similar devices but require datasheet verification for pin-to-pin or functional compatibility.
