Product details
Overview
SAK-TC277TC-64F200S DC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring three CPU cores (two TC1.6P and one TC1.6E), 4 MB program flash, 384 KB data flash, and integrated safety mechanisms including lockstep execution, ECC-protected memories, and Safety Management Unit (SMU). It operates at up to 200 MHz across the full industrial temperature range (–40 °C to +125 °C) and targets automotive powertrain and chassis control systems.
For engineers reviewing the SAK-TC277TC-64F200S DC datasheet, SAK-TC277TC-64F200S DC pinout, SAK-TC277TC-64F200S DC application, or SAK-TC277TC-64F200S DC equivalent, this page delivers verified core architecture details, validated BGA292 package mapping, confirmed safety features (SMU, HSM, lockstep), real-time peripheral timing (ASCLIN, ERAY, ETH), and functional alternatives for automotive ECU design.
Technical Context
The TC277 implements a heterogeneous multi-core architecture: two high-performance TC1.6P cores (200 MHz, dual MAC/FPU, 120 KB DSPR) and one power-efficient TC1.6E core (200 MHz, 112 KB DSPR), all binary-compatible and supported by lockstep shadowing for ASIL-D compliance. The on-chip bus system includes a 64-bit crossbar (SRI), 32-bit SPB, and SFI bridge enabling concurrent memory and peripheral access.
It integrates safety-critical subsystems including Memory Test Unit (MTU) with MBIST, Hardware I/O Monitor (IOM), and optional Hardware Security Module (HSM) supporting AES-128/256, SHA-256, and RSA-2048. Real-time peripherals include four ASCLIN channels (LIN v2.1 compliant, up to 50 MBaud), ERAY controller, Ethernet MAC (MII/RMII), and QSPI with slave/master timing support.
