Overview
The TLE9834QXXUMA1 is an automotive microcontroller from Infineon Technologies, featuring an XC800 core compatible with the standard 8051 architecture. It operates at a maximum clock frequency of 40 MHz and includes 64 kByte of Flash memory (with 4 kByte EEPROM emulation), 256 Byte RAM, and 3 kByte XRAM. The device integrates a LIN transceiver compliant with LIN 1.3/2.0/2.1 standards, two High Side Switches, and two Low Side Switches. Power management is handled by on-chip regulators providing 1.5 V for the core and 5.0 V for I/O ports, supporting a single supply voltage range of 3.0 V to 27 V.
Feature Summary
- XC800 Core: 8-bit MCU compatible with standard 8051, up to 40 MHz clock frequency.
- Integrated Memory: 64 kByte Flash, 256 Byte RAM, 3 kByte XRAM, and OTP/100TP memory.
- Power Switches: Two High Side Switches and two Low Side Switches with PWM functionality.
- Communication: On-chip LIN transceiver (LIN 1.3/2.0/2.1) and UART interface.
Applications
- Automotive body electronics applications
- LED driving and powering of switches
- Relay driver circuits
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type is VQFN-48-29 and check RoHS compliance status. Ensure design-in supports the specified 3.0 V to 27 V operating voltage range and -40 °C to 150 °C temperature specifications.
Selection Notes
Select this model for applications requiring integrated power switching alongside an 8051-compatible controller. Consider the 64 kByte Flash size for code requirements and verify that the two High Side and two Low Side switches meet load current needs. Ensure compatibility with LIN bus protocols if used as a node.
Part Context
This part belongs to the TLE983x product family designed for automotive environments. It is housed in a VQFN-48-29 package with a 0.5 mm pitch. The device is optimized for low power consumption with multiple sleep modes and cyclic wake-up capabilities suitable for terminal 30 connected applications.
Replacement Considerations
Check for updated revisions within the TLE983x family. Verify pinout compatibility if substituting with other variants like TLE9834QXXUMA2, noting potential differences in ordering suffixes or specific peripheral configurations.
