Overview
The TLE9835QX is an automotive microcontroller featuring an XC800 core compatible with the standard 8051 architecture, operating at up to 40 MHz. It integrates 64 kByte of Flash memory and includes a LIN transceiver compliant with LIN 2.1. The device provides two High Side Switches and two Low Side Switches for load driving. Power management includes on-chip regulators delivering 5.0 V (VDDP) and 1.5 V (VDDC), alongside a dedicated 5.0 V external supply (VDDEXT). Analog capabilities consist of an 8-channel 10-bit ADC (ADC1), a 10-channel 8-bit ADC (ADC2), and an operational amplifier. The unit operates within a junction temperature range of -40 °C to 150 °C.
Feature Summary
- XC800 core with up to 40 MHz clock frequency
- Integrated LIN transceiver supporting LIN 2.1
- Dual High Side and dual Low Side switches with PWM capability
- On-chip voltage regulators for 5.0 V I/O and 1.5 V core supplies
Applications
- Automotive body control modules
- LED lighting systems
- Relay driver applications
Procurement Notes
Verify component authenticity through authorized Infineon distribution channels. Confirm package integrity for the VQFN-48-29 form factor upon receipt. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering.
Selection Notes
Select this model when an 8051-compatible instruction set is required alongside integrated power switching. The inclusion of a LIN transceiver makes it suitable for networked automotive nodes. Verify that the 64 kByte Flash capacity meets firmware size constraints before finalizing the design.
Part Context
This component belongs to the TLE983x product family designed for cost-effective automotive solutions. It shares the XC800 core architecture with other members but offers specific peripheral configurations including 64 kByte Flash and five High Voltage Monitor inputs.
Replacement Considerations
Cross-reference with other TLE983x variants if different memory sizes or switch counts are needed. Ensure pin compatibility when substituting within the same package type.
