TC299TY128F300SBBKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring dual 300 MHz TC1.6P CPU cores, lockstep shadow core for ASIL-D compliance, 8 MB program flash (ECC-protected), 768 KB data flash for EEPROM emulation, and integrated 128-channel safety DMA. It targets automotive powertrain and chassis control systems requiring functional safety up to ISO 26262 ASIL-D.
For engineers reviewing the TC299TY128F300SBBKXUMA1 datasheet, TC299TY128F300SBBKXUMA1 pinout, TC299TY128F300SBBKXUMA1 application, or TC299TY128F300SBBKXUMA1 equivalent, key selection criteria include dual-core lockstep timing integrity, ERAY/ETH/ASCLIN interface coexistence, BGA516 thermal-mechanical suitability for engine control units, and flash ECC + SMU-based safety monitoring architecture.
Technical Context
The TC299TY128F300SBBKXUMA1 implements a deterministic real-time architecture with two independent TriCore™ TC1.6P CPUs operating at up to 300 MHz across full industrial temperature range (–40 °C to 150 °C), each backed by dedicated 120 KB DSPR and 16 KB PSPR RAM, plus shared SRI crossbar enabling concurrent memory/CPU access. Its safety subsystem includes SMU (Safety Management Unit), FSI (Fault Signaling Interface), and lockstep monitor with error injection capability.
It integrates multiple domain-specific peripherals: ERAY controller for deterministic automotive networking (up to 10 Mbps), 10/100 Ethernet MAC with MII/RMII support, 12x ASCLIN channels supporting LIN/UART/SPI, 4x SENT interfaces, and dual VADC/DSADC converters with 12-bit resolution and <1 µs conversion time - all accessible via hardware-protected memory-mapped registers with ECC on configuration space.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC297TP128F300SBBKXUMA1 | Same dual-core TriCore™ architecture but BGA416 package (smaller footprint, reduced peripheral count: no ETH, only 1 ERAY) | Targeted at cost-sensitive chassis modules where Ethernet connectivity and dual ERAY are not required | Select when board space is constrained and ASIL-D safety is needed without full TC299 peripheral set |
| TC397XPV128F300SBJXUMA1 | Successor AURIX™ TC3xx family; 300 MHz TriCore™ v2.0, 16 MB PFLASH, enhanced SMU, and added HSM security module | Required for new designs needing post-quantum crypto acceleration, secure boot, and extended lifecycle support beyond 2028 | Choose for greenfield projects demanding long-term availability, HSM-based secure firmware updates, and higher memory density |
Compared with TC297TP128F300SBBKXUMA1, this part adds Ethernet and dual ERAY for centralized vehicle networking; versus TC397XPV128F300SBJXUMA1, it lacks HSM and has lower flash capacity but offers mature qualification and broader toolchain support for legacy ECU platforms.

FAQ
What is the maximum junction temperature rating for TC299TY128F300SBBKXUMA1?
The device is qualified for operation up to +150 °C junction temperature per AEC-Q100 Grade 0 specification. Thermal design must maintain Tj ≤ 150 °C under worst-case power dissipation (3.2 W typical at 300 MHz, full peripheral activation), verified via θJA = 22 °C/W for standard 4-layer PCB with 1 oz copper and thermal vias under the BGA516 thermal pad.
Does TC299TY128F300SBBKXUMA1 support flash programming via JTAG?
Yes-it supports full flash programming, erase, and verification through standard JTAG (IEEE 1149.1) using Infineon's DAP interface and compatible debug probes (e.g., Lauterbach TRACE32, iSYSTEM winIDEA). The BROM bootloader enables field firmware updates via ASCLIN or ETH without requiring external programmer hardware.
How is the lockstep core monitored for fault detection?
Fault detection is performed continuously by the Lockstep Monitor Unit (LMU), which compares instruction fetches, ALU results, and register writes between primary and shadow cores cycle-by-cycle. Mismatches trigger immediate NMI, SMU fault signaling, and configurable safe state activation-including disabling PWM outputs and asserting FSI signals within ≤ 3 µs.
Can TC299TY128F300SBBKXUMA1 operate with a single 3.3 V supply?
No-it requires separate 1.3 V core supply (VDDP) and 3.3 V I/O supply (VDDIO). The internal EVR generates 1.3 V from an external 5 V or 3.3 V source, but direct 3.3 V application to VDDP violates absolute maximum ratings and will cause permanent damage. External 1.3 V regulation or EVR-enabled supply is mandatory.
