Product details
Overview
SAK-TC233LP-32F200N AC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with a lockstepped TC1.6E CPU core operating at up to 200 MHz, 2 MB program flash (PFLASH), 128 KB data flash (DFLASH) for EEPROM emulation, and integrated Ethernet MAC (MII/RMII), dual MultiCAN+ (6 CAN nodes), FlexRay v2.1, and GTM timer subsystem - deployed in automotive ADAS domain controllers and safety-critical engine control units.
For engineers reviewing the SAK-TC233LP-32F200N AC datasheet, SAK-TC233LP-32F200N AC pinout, SAK-TC233LP-32F200N AC application, or SAK-TC233LP-32F200N AC equivalent, key selection criteria include ASIL-D compliance support via SMU/MTU/ECC memory, real-time deterministic I/O handling via GTM and CCU6, and dual-core lockstep execution for functional safety certification per ISO 26262.
Technical Context
The SAK-TC233LP-32F200N AC implements a safety-certified TriCore architecture with hardware lockstep shadow core, ECC-protected memories (PFLASH, DFLASH, SRAM), and dedicated Safety Management Unit (SMU) that monitors clock, reset, and voltage domains. Its GTM module provides autonomous PWM generation, time-triggered I/O, and SENT signal decoding without CPU intervention.
It integrates two independent MultiCAN+ modules (3 CAN nodes each), supporting concurrent CAN FD and legacy CAN communication, plus an IEEE 802.3-compliant Ethernet MAC with MII/RMII PHY interface and full-duplex 10/100 Mbps operation - enabling high-bandwidth sensor fusion and gateway routing in distributed vehicle networks.

FAQ
What is the maximum junction temperature rating for SAK-TC233LP-32F200N AC?
The device is qualified for operation up to 150°C junction temperature, with thermal derating applied above 125°C ambient. The PG-TQFP-100-23 package includes an exposed thermal pad that must be soldered to a minimum 200 mm² copper pour on the PCB for effective heat dissipation under sustained 200 MHz operation.
Does SAK-TC233LP-32F200N AC support CAN FD?
Yes - both MultiCAN+ modules support CAN FD protocol up to 5 Mbps data phase, with flexible bit timing configuration and payload lengths up to 64 bytes. The CAN FD controllers are fully compatible with ISO 11898-1:2015 and support automatic protocol switching between classical CAN and CAN FD frames.
Is the Hardware Security Module (HSM) enabled in this variant?
No - the SAK-TC233LP-32F200N AC variant does not include an active HSM. While the silicon die contains the HSM block, it is disabled in this part number. For secure boot, cryptographic acceleration, or key provisioning, select the SAK-TC233L-32F200N AC variant which enables the HSM with AES-128/256 and SHA-256 engines.
What debug interfaces are supported and what are their pin assignments?
The device supports both IEEE 1149.1 JTAG (4-wire: TCK, TMS, TDI, TDO) and ARM CoreSight DAP (SWD-compatible 2-wire: SWDIO, SWCLK). JTAG pins are located on pins 12–15 (TCK/TMS/TDI/TDO); DAP uses pins 13–14 (shared with JTAG TMS/SWDIO) and pin 16 (SWCLK). TRSTn (pin 11) is JTAG-only and not used by DAP.
