Product details

Overview

SAK-TC234LP-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, 128 KB data flash for EEPROM emulation, and integrated Ethernet MAC (MII/RMII), dual MultiCAN+ (6 CAN nodes), FlexRay v2.1, and GTM timer subsystem. It targets automotive ASIL-D safety-critical control units such as engine management and ADAS domain controllers.

For engineers reviewing the SAK-TC234LP-32F200N AC datasheet, SAK-TC234LP-32F200N AC pinout, SAK-TC234LP-32F200N AC application, or SAK-TC234LP-32F200N AC equivalent, key selection criteria include ASIL-D compliance support via SMU/MTU/IOM, dual-core lockstep execution, ECC-protected memories, and hardware security module (HSM) option - all validated in Infineon's TC23x AC-step qualification.

Technical Context

The SAK-TC234LP-32F200N AC implements a safety-certified dual-core architecture: primary TC1.6E scalar core and lockstepped shadow core, both running at 200 MHz across −40°C to 125°C ambient. Its clock system includes System PLL and ERAY_PLL, enabling independent timing domains for real-time control and communication peripherals.

Peripheral integration follows AUTOSAR-compliant partitioning: two ASCLINs with LIN v2.1 support, four QSPI channels (50 Mbit/s), six CAN message objects per node (128 total), and IEEE 802.3-compliant ETH with MII/RMII PHY interface. All on-chip SRAM, Flash, and peripheral registers feature full ECC protection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SAK-TC233LP-32F200N AC	Same CPU, clock, and safety architecture but reduced peripheral set: no Ethernet MAC, only one MultiCAN+ (3 nodes), no FlexRay.	Suitable for cost-sensitive ASIL-B/C applications like body control modules where Ethernet/FlexRay are unnecessary.	Select when Ethernet/FlexRay connectivity and dual CAN domains are not required - lower BOM cost and smaller footprint.
SAK-TC237LP-32F200N AC	Same feature set as TC234 but in PG-LFBGA-292-6 package (292-pin ball grid array); adds second ETH port and extended GTM resources.	Targeted at high-end domain controllers requiring dual Ethernet ports (e.g., central gateway with OTA update capability).	Choose for designs needing higher I/O count, dual Ethernet, or enhanced GTM channel density - requires BGA assembly capability.

Compared with SAK-TC233LP-32F200N AC, the SAK-TC234LP-32F200N AC adds Ethernet and FlexRay for advanced networking, while SAK-TC237LP-32F200N AC extends those capabilities with dual ETH and larger pin count - making TC234 the optimal balance of ASIL-D features and TQFP manufacturability.

FAQ

What is the maximum operating temperature range for SAK-TC234LP-32F200N AC?

The SAK-TC234LP-32F200N AC is qualified for operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This rating applies to all core logic, memory, and integrated peripherals including CAN, FlexRay, and Ethernet MAC, as verified in Infineon's TC23x AC-step qualification report (V1.0, 2017-03).

Does SAK-TC234LP-32F200N AC include hardware cryptographic acceleration?

The SAK-TC234LP-32F200N AC supports an optional Hardware Security Module (HSM) variant. When enabled, the HSM provides dedicated AES-128/256, SHA-256, and RSA-2048 acceleration with secure key storage and tamper-resistant boot verification - but the base part number does not include HSM unless explicitly ordered with HSM suffix.

How many CAN nodes does SAK-TC234LP-32F200N AC support?

The SAK-TC234LP-32F200N AC integrates two independent MultiCAN+ modules, each supporting three CAN nodes - for a total of six fully configurable CAN controllers. Each node supports CAN FD up to 5 Mbps, with 128 shared message objects and hardware FIFO buffering for gateway functionality.

Is Ethernet PHY integrated into SAK-TC234LP-32F200N AC?

No, the SAK-TC234LP-32F200N AC contains only the IEEE 802.3-compliant Ethernet MAC layer with MII and RMII interfaces. An external PHY IC (e.g., LAN8720A or KSZ8081RNB) is required for physical layer signaling, transformer coupling, and ESD protection - as specified in section 3.21 of the TC23x datasheet.
