Product details
Overview
TC1767256F80HLADKXUMA1 from Infineon Technologies is a 32-bit TriCore V1.3.1 single-chip microcontroller featuring a 133 MHz super-scalar CPU, 2 MB program flash, 64 KB data flash (emulating 16 KB EEPROM), and dual CAN nodes. It integrates a Peripheral Control Processor (PCP2) running at 133 MHz, 72 KB LDRAM, and a MultiCAN module with 64 message objects-designed for real-time automotive powertrain and chassis control systems.
For engineers reviewing the TC1767256F80HLADKXUMA1 datasheet, TC1767256F80HLADKXUMA1 pinout, TC1767256F80HLADKXUMA1 application, or TC1767256F80HLADKXUMA1 equivalent, key selection criteria include its dual-core TriCore architecture, on-chip FPU, 32-channel ADC input capability, MSC/MLI serial expansion interfaces, and AEC-Q100 qualified operation across –40°C to 125°C ambient.
Technical Context
The TC1767256F80HLADKXUMA1 implements a tightly coupled dual-processor architecture: the main TriCore CPU handles high-level control and floating-point computation, while the PCP2 executes deterministic peripheral management tasks in parallel. Its bus structure includes a 64-bit local memory bus and a 32-bit system peripheral bus with LFI bridge, enabling concurrent memory and peripheral access without arbitration stalls.
Real-time responsiveness is enhanced by a 2×255-level priority interrupt system, 8-channel DMA supporting scatter-gather transfers, and hardware-accelerated peripherals including GPTA with LTCA2 for autonomous I/O timing, MultiCAN with FIFO buffering, and FADC with sub-microsecond conversion latency-critical for closed-loop engine control and brake actuation timing.
