Product details
Overview
TC297TB128F300SBBKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring dual 300 MHz TC1.6P CPU cores, 8 MB program flash (PFLASH), 768 KB data flash (DFLASH) for EEPROM emulation, and ECC-protected SRAM/flash memory. It integrates a 128-channel safety DMA, lockstep shadow core for ASIL-D compliance, and supports automotive powertrain and chassis control applications.
For engineers reviewing the TC297TB128F300SBBKXUMA1 datasheet, TC297TB128F300SBBKXUMA1 pinout, TC297TB128F300SBBKXUMA1 application, or TC297TB128F300SBBKXUMA1 equivalent, key selection criteria include dual-core lockstep operation, 300 MHz real-time performance, integrated Ethernet (ETH), E-Ray, and ASCLIN interfaces, and functional safety certification per ISO 26262 up to ASIL-D.
Technical Context
The TC297TB128F300SBBKXUMA1 implements a dual-core TriCore™ architecture with one master and one lockstepped shadow core, both operating at up to 300 MHz across the full industrial temperature range (–40 °C to +125 °C). Its SRI crossbar interconnect enables concurrent access to PFLASH, DFLASH, and multiple SRAM blocks (DSPR, PSPR, LMU) with deterministic latency.
It integrates safety-critical peripherals including E-Ray (flexible time-triggered communication), Ethernet MAC (10/100 Mbit/s), ASCLIN (UART/SPI/LIN), and DSADC (16-bit delta-sigma ADC with 1 MSps sampling rate), all supported by ECC, parity, and end-to-end data protection mechanisms aligned with ISO 26262 requirements.

FAQ
What is the maximum junction temperature rating for TC297TB128F300SBBKXUMA1?
The device is rated for operation up to 150 °C junction temperature, validated across the full industrial temperature range (–40 °C to +125 °C ambient) with derated performance above 105 °C. Thermal design must maintain θJA ≤ 28 °C/W using the recommended 10-layer PCB stackup with internal ground/power planes and thermal vias under the BGA292 package.
Does TC297TB128F300SBBKXUMA1 support AUTOSAR Classic and Adaptive platforms?
Yes-it provides full AUTOSAR Classic 4.3+ compliance with certified MCAL drivers for E-Ray, ETH, DSADC, and GPT, and supports Adaptive AUTOSAR via its POSIX-compliant SafeRTOS port and Ethernet/IP stack. The dual-core lockstep configuration satisfies ASIL-D requirements for both platforms' safety partitions.
How is flash memory protected against corruption during power loss or reset events?
All PFLASH and DFLASH blocks feature hardware ECC (SEC-DED), write-protection registers, and atomic sector erase/write operations. The Flash State Machine (FSM) enforces strict sequencing, and brown-out detection triggers immediate flash suspend to prevent partial writes-validated per ISO 26262 Annex D for Class 2 memory safety integrity.
Can TC297TB128F300SBBKXUMA1 operate in single-supply mode with only 3.3 V applied?
No-this variant requires separate 1.3 V core supply (VDDP_1P3) and 3.3 V I/O supply (VDDP_3V3). The internal voltage regulators are not enabled; external DC-DC converters must provide both rails. Single-supply operation is only supported on specific TC2xx derivatives with integrated regulators (e.g., TC27x with VDDP_5V input).
