ATA6285N-PNPW

RF Transmitter Overview

The ATA6285N-PNPW is a specialized integrated circuit designed for Tire Pressure Monitoring Systems (TPMS), functioning as both a control unit and transmitter. It integrates an AVR microcontroller with a low-frequency receiver, operating at 433 MHz using ASK or FSK modulation. The device features a 6 dBm output power and supports data rates up to 20 kbps. Packaged in a 32-pin QFN, it is engineered for surface mount PCB assembly, providing robust RF transmission capabilities for automotive tire monitoring applications.

RF Transmitter Feature Summary

• Integrates an AVR microcontroller with a dedicated LF receiver for comprehensive system control
• Supports ASK and FSK modulation schemes for reliable wireless communication
• Delivers high-efficiency RF transmission with 6 dBm output power capability

RF Transmitter Applications

• Tire pressure monitoring system control units
• Automotive tire valve stem transmitters
• Wireless sensor nodes for vehicle safety systems

RF Transmitter Procurement Notes

Verify the specific suffix PNPW against the manufacturer's official datasheet to confirm package type and temperature range. Ensure compatibility with existing TPMS antenna designs and regulatory requirements for 433 MHz operation. Cross-reference pin assignments with the latest Microchip documentation to prevent integration errors during PCB layout.

RF Transmitter Selection Notes

Select this component when designing compact TPMS solutions requiring integrated MCU and RF functions. It is suitable for applications needing moderate transmission power and support for standard automotive telemetry protocols. Consider thermal management within the QFN package and ensure the design accommodates the required LF receiver sensitivity for accurate tire status detection.

RF Transmitter Part Context

This part belongs to Microchip's family of TPMS control and transmitter ICs, which combine processing and radio frequency capabilities. It is related to variants like the ATA6286N, differing primarily in package configuration and specific interface details. These components are critical for modern vehicle safety systems, enabling real-time tire data transmission to the central ECU.

RF Transmitter Replacement Considerations

Direct substitutes may include other ATA628x series variants with compatible pinouts and electrical specifications. Verify functional equivalence regarding modulation types and output power before substitution. Consult Microchip's official cross-reference tools for confirmed alternative part numbers that meet the same automotive standards.
