ATA5771C-PXQW

RF Transmitter Overview

The ATA5771C-PXQW is a highly integrated UHF RF transmitter module by Microchip Technology, operating within the 868MHz to 928MHz frequency range. It combines an 8-bit AVR ATtiny44V microcontroller with a PLL transmitter, supporting ASK and FSK modulation. The device features a 5.5dBm output power and draws 9mA during transmission. It includes 4kB Flash, 256B EEPROM, and 256B SRAM memory. Communication is handled via an SPI interface, and it utilizes a PCB surface mount antenna in a 24-VQFN package with an exposed pad.

RF Transmitter Feature Summary

• Integrates an 8-bit AVR microcontroller with a UHF PLL transmitter for flexible programmability
• Supports ASK and FSK modulation schemes for robust wireless communication
• Utilizes a PCB surface mount antenna design for compact integration

RF Transmitter Applications

• General-purpose wireless communication systems
• UHF radio frequency identification (RFID) applications
• Industrial telemetry and remote monitoring

RF Transmitter Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status and check for obsolete part status indicators. Ensure supply chain documentation matches the specific 24-VQFN package variant. Validate that the received unit corresponds exactly to the ATA5771C-PXQW designation before integration into production workflows.

RF Transmitter Selection Notes

Select this component when a combined MCU and RF transmitter solution is required for UHF bands. Consider the 24-VQFN package constraints and SPI interface requirements. Evaluate the 5.5dBm output power against link budget needs. Assess the need for internal Flash and EEPROM storage for embedded logic versus external solutions.

RF Transmitter Part Context

This part belongs to the ATA5771 series of integrated transmitters. It differs from variants like the ATA5771C-PXQW-1 primarily in packaging or minor specification details rather than core functionality. The series targets applications requiring low-power, high-performance wireless data transmission in the UHF spectrum.

RF Transmitter Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing board layouts if considering alternative packages within the same family.
