Product details
Overview
SAK-TC234LC-24F133F AC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with a lockstepped TC1.6E CPU core operating up to 200 MHz, 2 MB program flash, 128 KB data flash (EEPROM-emulated), and integrated Ethernet MAC (MII/RMII), dual MultiCAN+ (6 CAN nodes), FlexRay v2.1, and GTM for autonomous I/O timing - deployed in automotive ADAS domain controllers and safety-critical ECU designs.
For engineers reviewing the SAK-TC234LC-24F133F AC datasheet, SAK-TC234LC-24F133F AC pinout, SAK-TC234LC-24F133F AC application, or SAK-TC234LC-24F133F AC equivalent, key selection criteria include ASCLIN/LIN support (v2.1/J2602), ECC-protected memory hierarchy, SMU-assisted ISO 26262 ASIL-D compliance readiness, and hardware security module (HSM) availability on select variants.
Technical Context
The SAK-TC234LC-24F133F AC implements a dual-core lockstep architecture where the shadow core continuously verifies the primary TC1.6E CPU's instruction execution, enabling real-time fault detection per ISO 26262 requirements. Its System PLL delivers stable 200 MHz core clock with jitter < ±50 ps RMS over temperature.
The on-chip GTM provides deterministic, offload-capable signal processing for PWM generation, capture/compare, and SENT sensor interfacing - independent of CPU load - while the dual MultiCAN+ modules support concurrent CAN FD and classical CAN traffic with 128 configurable message objects and hardware FIFOs.

FAQ
What is the maximum junction temperature rating for SAK-TC234LC-24F133F AC?
The device is qualified for operation up to +125 °C junction temperature, validated per AEC-Q100 Grade 1 requirements. Thermal derating begins at 105 °C ambient when using the PG-TQFP-144 package with standard PCB copper pour; full 200 MHz performance is maintained across this range with proper heatsinking.
Does SAK-TC234LC-24F133F AC include a hardware security module (HSM)?
The SAK-TC234LC-24F133F AC does not integrate the optional Hardware Security Module (HSM); that feature is present only in variants designated with "H" suffix (e.g., SAK-TC234LH-24F133F AC). This part supports secure boot via external HSM or software-based key management using its embedded SMU and protected memory regions.
Can the VADC measure signals above 3.3 V directly?
Yes - the VADC accepts input voltages from 0 V to 5.5 V when supplied by the dedicated VDDA_5V0 analog rail. It supports external voltage dividers and internal gain stages, enabling direct measurement of battery-sensed signals (e.g., 12 V rail monitoring) without external op-amp conditioning.
Is JTAG debug supported on this microcontroller?
Yes - the device supports IEEE 1149.1-compliant four-wire JTAG and alternative five-wire DAP (Device Access Port) interfaces for OCDS Level 1 debug access to CPU cores, DMA, and on-chip buses. Both interfaces operate at up to 25 MHz and support real-time trace via Embedded Trace Macrocell (ETM) when enabled.
