Product details

Overview

TC214L8F133NACKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring a lockstepped TC1.6E scalar CPU core operating at up to 133 MHz, 1 MB ECC-protected program flash, 96 KB data flash for EEPROM emulation, and integrated MultiCAN+ with 3 CAN nodes and 128 message objects. It targets automotive safety-critical control units requiring ASIL-D compliance.

For engineers reviewing the TC214L8F133NACKXUMA1 datasheet, TC214L8F133NACKXUMA1 pinout, TC214L8F133NACKXUMA1 application, or TC214L8F133NACKXUMA1 equivalent, key selection criteria include its dual-core lockstep architecture, on-chip SMU and MTU for functional safety, GTM-based timing autonomy, and QSPI/ASCLIN/SENT peripheral integration for sensor and actuator interfacing in powertrain and chassis systems.

Technical Context

This MCU implements a safety-certified dual-core architecture: one TC1.6E main core and a lockstepped shadow checker core, both running at 133 MHz across −40 °C to 125 °C ambient. The System PLL supports precise clock generation with jitter suppression, while the Safety Management Unit (SMU) monitors CPU, memory, and peripheral errors via dedicated alarms and error injection capability.

The on-chip bus structure comprises a 64-bit SRI crossbar for concurrent master access, a 32-bit SPB for peripherals, and an SFI bridge. Memory subsystem includes ECC-protected PFLASH, DFLASH, DSPR (88 KB), PSPR (8 KB), ICACHE (8 KB), and DRB - all validated by MTU with MBIST and initialization support.

ECC-Protected Memory Subsystem	All PFLASH, DFLASH, SRAM, and cache include single-bit correction/double-bit detection - mandatory for ASIL-D memory integrity.
MultiCAN+ with 128 Message Objects	Hardware FIFO buffering and gateway routing reduce CPU overhead by >70% vs. software-managed CAN stacks in multi-node gateways.
GTM Timer Module	Offloads complex PWM, capture, and time-triggered I/O tasks from CPU - enabling deterministic scheduling in safety-critical loops.
On-Chip Voltage Regulator (EVR)	Generates internal 1.3 V core supply from 5 V input; eliminates need for external DC-DC, reducing BOM count and layout complexity.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive safety microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TC234L8F133NACKXUMA1	Higher integration: adds Ethernet MAC (100BASE-T1), additional GTM TOM channels, and extended DFLASH (128 KB).	Required for Ethernet-enabled domain controllers; not drop-in due to pinout expansion and new PHY interface signals.	Select when 100BASE-T1 connectivity or increased GTM resource count is needed for next-gen ADAS or central compute modules.
TC224L8F133NACKXUMA1	Same core and peripherals but in PG-TQFP-100 package; reduced I/O count (100 pins vs. 144) and no GTM DTM unit.	Suitable for cost-sensitive chassis modules where full GTM feature set and CAN node count are not required.	Choose for simplified ECU designs with ≤100 signal I/O needs and no demand for dual-timer matrix (DTM) functionality.

Compared with TC214L8F133NACKXUMA1, TC234 offers Ethernet and expanded GTM for higher-compute gateways, while TC224 reduces pin count and GTM capability for compact chassis controllers - both retain identical CPU, safety architecture, and ASIL-D certification scope.

FAQ

What is the maximum junction temperature rating for TC214L8F133NACKXUMA1?

The device is rated for operation up to 150 °C junction temperature, validated across the full −40 °C to +125 °C ambient range with derating applied per thermal resistance values in the datasheet. This rating supports placement in high-temperature engine bay locations when paired with appropriate PCB copper pour and thermal vias.

Does TC214L8F133NACKXUMA1 support CAN FD with bit rate switching?

Yes, the integrated MultiCAN+ module supports CAN FD with flexible data rate (FDF = 1) and bit rate switching (BRS = 1), enabling arbitration at 1 Mbps and data phase up to 5 Mbps. Frame payload length extends to 64 bytes, verified per ISO 11898-1:2015 Annex C test cases.

How is the 1.3 V core supply generated internally?

The on-chip Embedded Voltage Regulator (EVR) converts the external 5.0 V supply (VDD5V) to 1.3 V for the CPU core and logic. It features programmable output voltage trim, soft-start, and overcurrent protection - eliminating need for external DC-DC converters in most automotive designs.

Is the BootROM (BROM) field-upgradable or fixed-function?

The BootROM is mask-programmed during fabrication and contains immutable firmware for secure boot, flash programming, and basic debug initialization. It cannot be modified in the field but supports authenticated firmware loading via UART, CAN, or DAP interface using keys stored in protected memory.
