Product details
Overview
TC299TP128F300SBCKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring dual 300 MHz TC1.6P super-scalar CPUs, lockstep shadow core for ASIL-D safety compliance, 8 MB ECC-protected program flash, 768 KB data flash for EEPROM emulation, and integrated 128-channel DMA. It targets automotive powertrain and chassis control systems requiring functional safety up to ISO 26262 ASIL-D.
For engineers reviewing the TC299TP128F300SBCKXUMA1 datasheet, TC299TP128F300SBCKXUMA1 pinout, TC299TP128F300SBCKXUMA1 application, or TC299TP128F300SBCKXUMA1 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 coverage across PFLASH/DFLASH/LMU memory domains.
Technical Context
The TC299TP128F300SBCKXUMA1 implements a deterministic real-time architecture with two independent TC1.6P cores operating at up to 300 MHz across –40°C to 125°C, each backed by dedicated 120 KB DSPR and 16 KB PSPR SRAM, plus shared 8 KB ICACHE/DCACHE. Core 1 runs in lockstep with its shadow for fault detection.
Its on-chip memory subsystem includes 8 MB PFLASH with single-bit error correction and double-bit error detection (SECDED), 768 KB DFLASH configured for wear-leveling EEPROM emulation, and 32 KB LMU with parity protection. The 64-bit SRI crossbar enables concurrent CPU, DMA, and peripheral access without arbitration stalls.

FAQ
What is the maximum junction temperature rating for TC299TP128F300SBCKXUMA1?
The device is qualified for operation up to +125°C junction temperature, validated per AEC-Q100 Grade 1 requirements. Thermal design must maintain Tj ≤ 125°C under worst-case ambient, power dissipation, and PCB copper pour conditions-verified using the Ψjt parameter (1.8°C/W) from the datasheet's thermal characteristics table.
Does TC299TP128F300SBCKXUMA1 support JTAG-based flash programming in-system?
Yes-it supports full in-system programming via JTAG using the DAP interface, including PFLASH/DFLASH erase, program, and verify operations. TRSTN, TCK, TMS, TDI, and TDO pins implement IEEE 1149.1 compliance, and the embedded bootloader enables secure field updates without external programmers.
How is the Emergency Stop (ESTOP) function implemented electrically and logically?
ESTOP is an asynchronous, active-high input that directly gates CPU clock domains and freezes all peripheral state machines within one clock cycle. It does not require software polling or interrupt handling-assertion forces immediate core halt, disables all outputs, and asserts ESTOP_ACK to downstream safety monitors, meeting ISO 26262 hardware fault tolerance requirements.
Can the 768 KB DFLASH be used for both EEPROM emulation and secure key storage simultaneously?
Yes-DFLASH sectors can be partitioned: one region configured for wear-leveling EEPROM emulation (via HAL library), another locked under HSM control for AES key storage with read/write protection enforced by the embedded security monitor. Access isolation is hardware-enforced via memory protection units (MPUs) and HSM privilege gates.
