Product details
Overview
TC1767256F133HRADKFQMA1 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 and chassis control units requiring deterministic real-time response.
For engineers reviewing the TC1767256F133HRADKFQMA1 datasheet, TC1767256F133HRADKFQMA1 pinout, TC1767256F133HRADKFQMA1 application, or TC1767256F133HRADKFQMA1 equivalent, key selection criteria include TriCore real-time execution capability, on-chip flash endurance (100k write cycles), CAN FD readiness via MultiCAN message object flexibility, and PCP2 co-processor support for autonomous peripheral handling without CPU load.
Technical Context
The TC1767 implements a tightly coupled dual-core architecture: the main TriCore CPU executes application code with 4-stage pipeline and single-precision FPU, while the dedicated 133 MHz PCP2 handles time-critical I/O tasks using 8 KB PRAM and 16 KB CMEM. Both cores share access to the 64-bit local memory bus and LFI bridge to the 32-bit system peripheral bus.
Its peripheral subsystem includes a 2-node MultiCAN controller with 64 configurable message objects, GPTA+LTCA2 for digital signal filtering and autonomous I/O timing, and dual 10-bit ADCs supporting 32-channel sampling at up to 1.2 MSps - all synchronized via centralized clock generation unit with PLL and multiple clock domains.
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 deterministic real-time control with <100 ns interrupt latency. |
| Max Clock Frequency | 133 MHz across full industrial temperature range (–40°C to +125°C) - guarantees timing-critical task execution in engine control units. |
| Flash Memory | 2 MB PFlash + 64 KB DFlash (16 KB EEPROM-equivalent) - supports A/B firmware swapping and EEPROM emulation for calibration data storage. |
| RAM | 72 KB LDRAM + 24 KB SPRAM + 8 KB OVRAM - provides low-latency data buffering for control loops and sensor preprocessing. |
| ADC | Two 10-bit SAR ADCs with 32 input channels and 1.2 MSps aggregate sampling rate - enables simultaneous acquisition of crankshaft, camshaft, and throttle position signals. |
| MultiCAN | 2 CAN nodes, 64 message objects, FIFO buffering, and gateway functionality - supports multi-bus vehicle network routing without host CPU intervention. |

Pinout & Package
TC1767256F133HRADKFQMA1 is housed in a PG-LQFP-176-5 package (176-pin Low-Quad Flat Package, 24 × 24 mm, 0.5 mm pitch, exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP / VSSP | Core Power Supply / Ground | Dedicated 1.3 V supply domain for CPU/PCP2 logic - requires low-noise regulation and local decoupling for jitter-sensitive timing. |
| VDDA / VSSA | Analog Power Supply / Ground | Separate 5 V analog domain for ADC and oscillator - isolation prevents digital switching noise from degrading 10-bit conversion accuracy. |
| OSCIN / OSCOUT | Crystal Oscillator Input/Output | Supports 1–20 MHz external crystal - feeds PLL for generating internal 133 MHz core clock and peripheral clocks with programmable dividers. |
| ASC0TX / ASC0RX | Asynchronous Serial Channel 0 Transmit/Receive | Full-duplex UART interface with baud-rate generator and framing error detection - used for diagnostic communication with ECU test equipment. |
| CAN0TX / CAN0RX | CAN Node 0 Transmit/Receive | Differential CAN physical layer interface compliant with ISO 11898-2 - connects directly to high-speed CAN transceiver for powertrain bus communication. |
| ADCTRIG0 | ADC Start-of-Conversion Trigger | Hardware-synchronized trigger input - allows precise alignment of ADC sampling to engine crank angle events via GPTA-generated pulse. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-core deterministic execution | CPU + PCP2 operate concurrently at 133 MHz with shared memory and hardware semaphore support - eliminates software polling for inter-processor coordination in safety-critical routines. |
| On-chip flash with EEPROM emulation | 64 KB DFlash supports 100k write cycles and wear leveling - enables robust storage of adaptive learning parameters (e.g., fuel trim tables) without external EEPROM. |
| MultiCAN with message object arbitration | 64 assignable message objects with priority-based hardware arbitration - ensures guaranteed delivery of critical torque request messages ahead of non-urgent diagnostics traffic. |
| GPTA with LTCA2 timer cells | Programmable digital filter chains and independent compare/capture units - enable glitch-free PWM output for ignition coil drivers and accurate RPM measurement from Hall sensors. |
| Real-time debug via OCDS | On-Chip Debug Support with trace buffer and JTAG/DAP interfaces - permits non-intrusive instruction tracing and breakpoint insertion during live engine operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive real-time microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC275T128F133NACXUMA1 | Newer TriCore V1.6.2 core, 200 MHz max, 4 MB PFlash, integrated Ethernet MAC - lacks MSC interface but adds HSM security module. | Better suited for next-gen ADAS domain controllers requiring secure OTA updates and time-sensitive networking. | Select when migrating to AUTOSAR Adaptive or requiring hardware security for cybersecurity-critical functions. |
| SPC56EL70L5CEFAY | Power Architecture e200z7 core, 180 MHz, 2 MB Flash, 256 KB RAM - no PCP2, uses DMA-based peripheral offload instead of dedicated processor. | Targeted at cost-optimized body control modules where deterministic I/O offload is less critical than BOM reduction. | Prefer for legacy Power Architecture toolchain continuity or lower-cost entry-level powertrain variants without complex sensor fusion. |
Compared with TC1767256F133HRADKFQMA1, the TC275 offers higher performance and security but requires updated compiler and debug infrastructure; the SPC56EL70 trades dual-core determinism for broader ecosystem support and lower licensing cost - making it viable only where PCP2 autonomy is not required for safety-critical timing.

FAQ
What is the operating temperature range for TC1767256F133HRADKFQMA1?
The TC1767256F133HRADKFQMA1 is qualified for industrial temperature range –40°C to +125°C ambient, with full 133 MHz operation guaranteed across this range. Its die temperature sensor and thermal shutdown circuitry provide real-time junction monitoring, enabling dynamic frequency scaling in high-temperature environments such as under-hood engine control applications.
Does TC1767256F133HRADKFQMA1 support AUTOSAR-compliant software stacks?
Yes - the TC1767 is fully supported by AUTOSAR 4.x Basic Software (BSW) modules including ECU State Manager, Watchdog Manager, and CAN Driver, with certified MCAL drivers from Vector and Elektrobit. Its PCP2 co-processor enables AUTOSAR OS extensions for time-triggered communication and safety monitor partitions.
How is flash memory protected against corruption during power loss?
The device implements hardware-assisted flash protection including ECC on all PFlash and DFlash blocks, atomic page erase/write operations, and a dedicated Flash Protection Register (FPROT) that locks sectors against accidental writes. Power-loss recovery is handled via boot ROM routines that validate flash checksums and roll back incomplete updates using shadow sector mechanisms.
Can the PCP2 processor be used independently of the main CPU?
Yes - the PCP2 executes its own 16 KB CMEM code and manages 8 KB PRAM data autonomously, with dedicated interrupt vectors and DMA channels. It can run real-time I/O tasks (e.g., CAN message filtering, ADC post-processing) without CPU intervention, communicating via shared memory with hardware semaphores and mailbox registers for synchronization.
