Product details
Overview
TC1796256F150EBEKDUMA1 from Infineon Technologies is a 32-bit TriCore V1.3 single-chip microcontroller with 150 MHz CPU clock, 2 MB program flash (PFLASH) with ECC, 128 KB data flash (DFLASH), and dual CAN nodes supporting TTCAN. It integrates a Peripheral Control Processor (PCP2), 16-channel DMA, and operates across the full automotive temperature range (−40 °C to +125 °C) for engine control unit applications.
For engineers reviewing the TC1796256F150EBEKDUMA1 datasheet, TC1796256F150EBEKDUMA1 pinout, TC1796256F150EBEKDUMA1 application, or TC1796256F150EBEKDUMA1 equivalent, key selection considerations include its 150 MHz real-time performance, integrated MultiCAN with 4 nodes and 128 message objects, FADC sub-280 ns conversion time, and P/PG-BGA-416-4 package compatibility with automotive ECU thermal and routing constraints.
Technical Context
The TC1796 implements a super-scalar TriCore V1.3 CPU with 4-stage pipeline, single-precision FPU, and bit-manipulation acceleration-enabling deterministic execution in safety-critical powertrain control. Its dual-bus architecture includes 64-bit Local Memory Buses and 32-bit System/Remote Peripheral Buses, enabling concurrent memory access and peripheral servicing without CPU intervention.
On-chip peripherals include two ASC/SSC/MSC/MLI interfaces, a MultiCAN module with TTCAN support on one node, two 16-channel ADCs (8/10/12-bit selectable), and a dedicated 4-channel FADC with hardware comb filtering. The PCP2 co-processor executes real-time I/O tasks independently using 16 KB PRAM and 32 KB CMEM.

FAQ
What is the maximum operating junction temperature for TC1796256F150EBEKDUMA1?
The device is rated for full operation across −40 °C to +125 °C ambient temperature, with a maximum junction temperature of +150 °C under specified thermal conditions per datasheet Section 4.1.4. This rating is validated for continuous operation in engine bay environments with appropriate PCB copper pour and heatsinking.
Does TC1796256F150EBEKDUMA1 support JTAG-based flash programming in-system?
Yes-it supports OCDS Level 2-compliant JTAG programming via TRST/TCK/TMS/TDI/TDO pins. Flash programming is performed using Infineon's DAS-2 debugger or compatible tools with TriCore-specific firmware loaders, enabling field updates and production programming without removing the device.
How many CAN message objects are supported, and are they configurable per node?
The MultiCAN module supports 128 free-assignable message objects distributed across four CAN nodes. Each object is individually configurable for ID, mask, direction (TX/RX), FIFO assignment, and priority-allowing flexible gateway, filtering, and buffering strategies without CPU intervention.
Is the FADC output directly accessible to the CPU, or does it require PCP2 intervention?
FADC results are written to dedicated DPRAM locations accessible by both CPU and PCP2. While the CPU can read converted values directly, the FADC's hardware comb filter and decimation logic operate autonomously-requiring no CPU cycles for data reduction, unlike standard ADC post-processing.
