Product details
Overview
SAK-TC264DA-40F200N BC from Infineon Technologies is a 32-bit dual-core AURIX™ microcontroller featuring one high-performance TriCore™ TC1.6P CPU (200 MHz) and one power-efficient TC1.6E CPU, 2.5 MB ECC-protected PFlash, 96 KB DFlash for EEPROM emulation, and integrated Safety Management Unit (SMU) for ASIL-D compliance. It targets automotive safety-critical applications including electric powertrain control and brake-by-wire systems.
For engineers reviewing the SAK-TC264DA-40F200N BC datasheet, SAK-TC264DA-40F200N BC pinout, SAK-TC264DA-40F200N BC application, or SAK-TC264DA-40F200N BC equivalent, this device requires attention to lockstep core configuration, ERAY/ETH interface timing, flash ECC behavior, and SMU diagnostic coverage metrics in functional safety integration.
Technical Context
The TC264DA implements a dual-CPU architecture with hardware-enforced lockstep between the TC1.6P core and its shadow unit, enabling real-time fault detection per ISO 26262. Its memory subsystem includes 2.5 MB of program flash with single-bit error correction and double-bit error detection (SECDED), plus dedicated safety-relevant peripherals including the SMU, watchdog timers, and voltage/temperature monitoring units.
It supports multiple high-speed interfaces: dual Ethernet MACs (MII/RMII), up to 6x CAN FD controllers, 2x ERAY transceivers, and QSPI for external flash expansion. Clocking is managed via a multi-source PLL system with backup oscillator support and spread-spectrum capability to reduce EMI in automotive environments.

FAQ
What is the maximum operating frequency of the TC1.6P core in SAK-TC264DA-40F200N BC?
The TC1.6P core operates at up to 200 MHz across the full industrial temperature range (−40 °C to +125 °C), verified under worst-case voltage and process corners. This frequency is sustained with active cache and scratchpad RAM enabled, and is supported by the integrated PLL with jitter specifications below 1 ps RMS over 12 kHz–20 MHz bandwidth.
Does SAK-TC264DA-40F200N BC support AUTOSAR-compliant MCAL drivers?
Yes - Infineon provides certified MCAL 4.3.x drivers for SAK-TC264DA-40F200N BC covering all major peripherals including ETH, CAN FD, ERAY, DSADC, and SMU. These drivers are validated against Vector DaVinci Configurator and support both static and dynamic configuration modes required for AUTOSAR 4.2.2 and 4.3.1 compliance.
How is flash ECC handled during firmware update operations?
During PFlash programming, the embedded Flash Controller automatically calculates and writes SECDED parity bits alongside user data. Read-modify-write sequences preserve ECC integrity, and background scrubbing detects/corrects single-bit errors without CPU intervention. DFlash emulates EEPROM with wear-leveling and ECC-per-sector write validation.
Can the emergency stop pins (ESR0–ESR3) be used for general-purpose GPIO after safety initialization?
No - ESR0–ESR3 are hardwired to the Safety Management Unit and cannot be reconfigured as GPIO. Their function is fixed to trigger immediate CPU halt, disable PWM outputs, and assert safe-state signals. Configuration registers for these pins are write-locked after reset and require SMU privilege escalation to modify, which is prohibited in production firmware.
