Product details

Overview

TC377TP96F300SAAKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring three lockstep-capable TC1.6.2P CPU cores operating up to 300 MHz, 6 MB program flash, 256 KB data flash (EEPROM-emulated), and integrated safety features including SMU, MTU, and ECC-protected memories. It targets automotive ASIL-D functional safety applications such as electric powertrain control and brake-by-wire systems.

For engineers reviewing the TC377TP96F300SAAKXUMA1 datasheet, TC377TP96F300SAAKXUMA1 pinout, TC377TP96F300SAAKXUMA1 application, or TC377TP96F300SAAKXUMA1 equivalent, key selection criteria include dual CAN FD + FlexRay™ support, hardware security module (HSM) availability, 12-channel VADC with 0–5.5 V input range, DSADC for high-precision current sensing, and LFBGA-292 package compatibility with automotive PCB layout constraints.

Technical Context

The TC377TP96F300SAAKXUMA1 implements a triple-core TriCore™ architecture with two lockstepped CPU pairs for fault-tolerant execution, supported by a 64-bit SRI crossbar interconnect and ECC-protected memory subsystem. Its safety infrastructure includes a dedicated Safety Management Unit (SMU), Memory Test Unit (MTU), and Hardware I/O Monitor (IOM) for runtime diagnostics.

It integrates dual MCMCAN modules (each supporting CAN FD up to 5 Mbps), a FlexRay™ E-Ray v2.1 controller with dual channels, IEEE 802.3 Ethernet MAC with RMII/MII, and 15 SENT channels for sensor interfacing - all synchronized via the GTM timer module for deterministic timing in distributed real-time control loops.

ADAS Domain Controller

Charging Station Control

Use Scenario: Sensor aggregation hub fusing radar, camera, and ultrasonic inputs for L2+ automated driving functions.

IC Role / Device Role / Timing Role: Central timing master synchronizing multi-sensor timestamps via GTM; runs Ethernet AVB stack for camera streaming and CAN FD for radar coordination.

Use Value: IEEE 802.3 MAC with hardware timestamping achieves <100 ns time sync accuracy across 10+ sensors; QSPI interfaces directly to LPDDR3 for frame buffering.

Use Scenario: Smart AC/DC charging controller managing grid communication (IEC 61851), thermal monitoring, and contactor sequencing.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TC387TP128F300SAAKXUMA1	128 KB RAM (vs. 96 KB), additional GTM slice, same 300 MHz clock and safety features.	Better suited for complex ADAS domain controllers requiring larger real-time buffer space and extra timer resources.	Select when >96 KB RAM or extended GTM channel count is required; pin-compatible but higher BOM cost.
S32K344WAT0MLT	NXP S32K3 32-bit Arm Cortex-M7 core; 300 MHz, ASIL-D certified, 8 MB flash, no integrated FlexRay™ or E-Ray.	Preferred for CAN FD/Ethernet-only architectures where FlexRay™ legacy integration is unnecessary.	Choose if Arm ecosystem tooling (S32DS, MCAL) is mandated; lacks native FlexRay™ PHY support, requiring external transceiver.

Compared with TC377TP96F300SAAKXUMA1, TC387 offers expanded memory and GTM capacity for scaling ADAS workloads, while S32K344 provides Arm-based development continuity but omits FlexRay™ - making TC377 the only option for brownfield chassis platforms requiring E-Ray v2.1 compliance.

FAQ

What is the maximum junction temperature rating for TC377TP96F300SAAKXUMA1?

The TC377TP96F300SAAKXUMA1 is rated for maximum junction temperature of 150 °C, validated per AEC-Q100 stress test conditions. This allows operation in under-hood environments up to 125 °C ambient with appropriate PCB copper pour and thermal vias beneath the LFBGA-292 thermal pad.

Does TC377TP96F300SAAKXUMA1 support CAN FD and classical CAN on the same MCMCAN module?

Yes - each MCMCAN module supports simultaneous CAN FD (up to 5 Mbps) and classical CAN (1 Mbps) operation via independent message objects and bit-rate configuration registers. Both protocols share the same TX/RX pins but use separate FIFOs and interrupt vectors for deterministic scheduling.

Is the Hardware Security Module (HSM) enabled by default in TC377TP96F300SAAKXUMA1?

No - the HSM is present but disabled at power-on reset. It must be explicitly enabled via the HSM_CTRL register after verifying secure boot signature and loading trusted firmware into protected HSM RAM. Activation requires successful authentication using factory-programmed unique device secret keys.

What debug interfaces does TC377TP96F300SAAKXUMA1 support, and are they accessible during safety-critical runtime?

It supports four-wire JTAG (IEEE 1149.1) and ARM CoreSight DAP interfaces. Debug access is restricted during ASIL-D runtime: OCDS Level 1 debugging remains active for non-intrusive trace and register read, but breakpoint insertion or code injection is blocked by the SMU unless safety state is explicitly downgraded.
