Product details
Overview
TC1796256F150EBEKDUMA2 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 16-channel ADC units supporting 8/10/12-bit resolution. It integrates a Peripheral Control Processor (PCP2), MultiCAN module with four nodes and 128 message objects, and operates across the full automotive temperature range (−40°C to +125°C) for engine control unit applications.
For engineers reviewing the TC1796256F150EBEKDUMA2 datasheet, TC1796256F150EBEKDUMA2 pinout, TC1796256F150EBEKDUMA2 application, or TC1796256F150EBEKDUMA2 equivalent, key selection criteria include real-time interrupt latency, CAN-TTCAN support, FADC sub-280 ns conversion time, and P/PG-BGA-416-4 package compatibility with automotive ECU PCB layouts.
Technical Context
The TC1796 implements a super-scalar TriCore V1.3 CPU with 4-stage pipeline, single-precision FPU, and hardware bit manipulation, enabling deterministic execution in safety-critical automotive control loops. Its dual-bus architecture separates 64-bit local memory buses (for flash/SRAM access) from 32-bit system peripheral bus (SPB) and remote peripheral bus (RPB), isolating high-bandwidth DMA transfers from real-time peripheral servicing.
On-chip peripherals include two ASC/SSC/MSC/MLI interfaces, a MultiCAN controller with TTCAN-capable node, GPTA0/GPTA1 timer arrays with LTCA2 for autonomous I/O filtering, and parallel ADC0/ADC1 plus dedicated FADC with concatenated comb filters - all synchronized via a PLL-based clock generation unit supporting core voltage at 1.5 V and I/O at 3.3 V.
