LX3302AQPW-EASY

Application Specific Microcontrollers Overview

The LX3302AQPW-EASY is an inductive sensor interface IC featuring a built-in oscillator for driving primary coils and two independent analog channels with demodulation. It integrates a 32-bit Cortus APS1 RISC MCU, two 13-bit ADCs, one 12-bit DAC, and one 16-bit PWM. The device supports SENT and asynchronous PSI5 outputs, digital calibration via nonvolatile EEPROM, and fault detection. It operates on a wide supply voltage range of 4.0V to 11.0V and functions within a temperature range of -40°C to +150°C. Packaged in a 14-lead TSSOP, it is AEC-Q100 certified and supports ISO26262 ASIL B.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm packaging type and compliance status. Confirm that the EASY variant designation aligns with intended system integration requirements. Ensure compatibility with host system voltage levels and interface protocols before procurement.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring high-reliability inductive position sensing with integrated signal processing. Verify that the 14-TSSOP package fits the PCB layout constraints. Ensure the host system can support the required SENT or PSI5 communication protocols and that the operating temperature range meets environmental specifications.

Application Specific Microcontrollers Part Context

The LX3302A series is designed for interfacing with inductive sensors, providing a complete solution from signal conditioning to digital output. It replaces discrete components by integrating oscillators, amplifiers, ADCs, and microcontrollers into a single chip, reducing system complexity and improving accuracy through factory calibration capabilities stored in EEPROM.

Application Specific Microcontrollers Replacement Considerations

Check for direct substitutes within the LX3302A family, such as LX3302AQPW-TR, which shares identical electrical characteristics but differs in tape-and-reel packaging. Ensure any replacement maintains AEC-Q100 Grade 0 certification and ASIL B support if safety-critical functionality is required.
