Product details

Overview

TC1767256F133HLADKXUMA1 from Infineon Technologies is a 32-bit TriCore V1.3.1 single-chip microcontroller featuring a 133 MHz super-scalar CPU with integrated FPU, 2 MB program flash, 64 KB data flash (emulating EEPROM), and dual-core architecture combining CPU and Peripheral Control Processor (PCP2). It integrates MultiCAN, GPTA, ASC/SSC serial interfaces, and ADC with 32 analog inputs - deployed in automotive powertrain control units requiring deterministic real-time response.

For engineers reviewing the TC1767256F133HLADKXUMA1 datasheet, TC1767256F133HLADKXUMA1 pinout, TC1767256F133HLADKXUMA1 application, or TC1767256F133HLADKXUMA1 equivalent, key selection criteria include its 133 MHz operation across full temperature range, dual-core interrupt arbitration (2 × 255 priority levels), PFlash/DFlash endurance specs, and PG-LQFP-176 package compatibility with automotive PCB layout constraints.

Technical Context

The TC1767256F133HLADKXUMA1 implements a tightly coupled dual-processor architecture: the main TriCore CPU executes application code while the PCP2 handles time-critical peripheral tasks at 133 MHz using dedicated 8 KB PRAM and 16 KB CMEM. Its bus hierarchy includes a 64-bit local memory bus for CPU–Flash–LDRAM access and a 32-bit system peripheral bus (SPB) connecting all on-chip peripherals.

Real-time determinism is enforced via hardware-supported features: a 8-channel DMA controller with scatter-gather support, a flexible interrupt system with two independent priority arbitration matrices, and the MultiCAN module supporting 64 message objects with FIFO buffering and gateway functionality - enabling concurrent CAN FD-ready communication without CPU intervention.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	TriCore V1.3.1 super-scalar 32-bit core with 4-stage pipeline and single-precision FPU - enables floating-point math in motor control loops without software emulation overhead.
Max Clock Frequency	133 MHz over full industrial temperature range (−40°C to +125°C) - guarantees deterministic timing for safety-critical engine management functions.
Memory	2 MB PFlash + 64 KB DFlash (16 KB EEPROM-equivalent) + 72 KB LDRAM - supports AURIX-compatible firmware updates and parameter storage with wear leveling.
Peripheral Integration	MultiCAN (2 nodes, 64 message objects), 2×ASC, 2×SSC, MSC, MLI, GPTA+LTCA2 - eliminates need for external CAN controllers and complex timer ICs in ECU designs.
Analog Input	32-channel ADC with dedicated FADC block - provides sub-microsecond sampling for cylinder pressure sensing and knock detection.
Package	PG-LQFP-176 (24 × 24 mm, 0.5 mm pitch) - compatible with standard automotive reflow profiles and automated optical inspection (AOI) workflows.

Pinout & Package

TC1767256F133HLADKXUMA1 is housed in a PG-LQFP-176 package: thermally enhanced low-profile quad flat pack with 176 leads, 0.5 mm pitch, and exposed thermal pad for efficient heat dissipation in engine bay environments.

Pin/Terminal	Circuit Role	Design Meaning
VDDP, VDDM	Digital Power Supply	1.3 V core supply pins - require tight regulation and local decoupling to maintain 133 MHz stability under transient load.
VDDA, VSSA	Analog Power/Ground	Separate 5 V analog domain for ADC reference - isolation prevents digital noise from degrading 12-bit conversion accuracy.
XTAL1/XTAL2	Crystal Oscillator Input/Output	Supports 10–20 MHz fundamental-mode crystals - feeds PLL for precise 133 MHz system clock generation with jitter < 100 ps RMS.
TSIN	Die Temperature Sensor Input	Analog input to internal temperature sensor - enables real-time thermal throttling of CPU/PCP2 during high-load conditions.
TRST, TCK, TMS, TDI, TDO	JTAG Debug Interface	IEEE 1149.1-compliant boundary scan and OCDS debug - allows non-intrusive real-time trace and calibration during ECU validation.

Key Features

Feature	Design Value
Dual-core real-time execution	CPU + PCP2 operate concurrently at 133 MHz with shared memory coherency - enables separation of safety-critical control (PCP2) and diagnostics/UI (CPU) without inter-core latency penalties.
MultiCAN with message object FIFO	64 configurable message objects with hardware FIFO buffering - reduces CAN bus arbitration delay and supports ISO 11898-1 compliant gateway routing between vehicle domains.
GPTA + LTCA2 timer subsystem	Programmable digital signal filtering, edge capture, PWM generation, and quadrature decoding - replaces discrete logic in motor position feedback and injector timing circuits.
FADC with sub-μs sampling	Fast ADC block optimized for <1 μs conversion time on critical channels - meets timing requirements for combustion chamber pressure monitoring in gasoline direct injection systems.
BootROM with flash security	16 KB ROM containing secure boot loader and tuning protection logic - prevents unauthorized firmware modification in production ECUs per UNECE R155 compliance.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TC1797256F133HLADKXUMA1	Successor with TriCore V1.6.2 core, 200 MHz max frequency, 4 MB PFlash, and enhanced safety features (ASIL-D ready).	Required for new ASIL-D designs; not drop-in compatible due to changed peripheral register map and larger LQFP-292 package.	Select when developing next-gen powertrain systems requiring ISO 26262 ASIL-D certification and higher compute throughput.
TC275T128F133NACAKXUMA1	AURIX™ TC2xx family part with TriCore V1.6.2, 300 MHz, 2 MB PFlash, and integrated HSM for secure boot.	Targets post-2018 automotive platforms; lacks legacy ASC/SSC peripherals but adds Ethernet AVB and PCIe.	Choose for infotainment-integrated ECUs needing secure OTA update capability and future-proof connectivity.

Compared with TC1767256F133HLADKXUMA1, the TC1797 offers higher clock speed and safety certification but requires PCB redesign, while the TC275 provides modern security and networking at the cost of legacy peripheral support - making the TC1767 optimal for cost-sensitive, ASIL-B-compliant ECU replacements.

FAQ

What is the maximum operating temperature range for TC1767256F133HLADKXUMA1?

The TC1767256F133HLADKXUMA1 is rated for continuous operation from −40°C to +125°C ambient temperature, validated per AEC-Q100 Grade 1 requirements. Its die temperature sensor (TSIN pin) enables dynamic thermal derating above 110°C junction temperature, preserving functional integrity in under-hood environments.

Does TC1767256F133HLADKXUMA1 support CAN FD?

No - the integrated MultiCAN module supports Classical CAN (ISO 11898-1) up to 1 Mbps only. It does not implement CAN FD frame format, bit rate switching, or extended data length. For CAN FD capability, Infineon recommends migrating to the AURIX™ TC3xx family.

How is flash memory protected against unauthorized access or corruption?

Protection is implemented via BootROM-based tuning protection logic, configurable flash lock bits per sector, and hardware-assisted write-protection for DFlash. The device supports secure boot verification using stored cryptographic signatures - preventing execution of unauthenticated firmware images.

Can TC1767256F133HLADKXUMA1 be used in ASIL-D applications?

No - the TC1767256F133HLADKXUMA1 is qualified to ASIL-B per ISO 26262:2018, with documented FMEDA results and safety mechanisms including lockstep-capable peripherals and ECC on critical memories. ASIL-D compliance requires the successor TC1797 or AURIX™ TC3xx devices.
