Infineon Technologies SAK-TC234LP-16F200F AC

Overview

SAK-TC234LP-16F200F 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 - deployed in automotive ADAS domain controllers and safety-critical ECU platforms.

For engineers reviewing the SAK-TC234LP-16F200F AC datasheet, SAK-TC234LP-16F200F AC pinout, SAK-TC234LP-16F200F AC application, or SAK-TC234LP-16F200F AC equivalent, key selection criteria include ASIL-D compliance support via SMU/MTU/ECC memory, dual-core lockstep execution, hardware security module (HSM) option, and deterministic real-time peripheral timing for automotive networking and sensor fusion.

Technical Context

The SAK-TC234LP-16F200F AC implements a safety-certified TriCore architecture with binary compatibility to TC1.6P, featuring dual-core lockstep operation and ECC-protected memories across PFLASH, DFLASH, SRAM, and peripherals. Its clock system includes independent System PLL and ERAY_PLL for synchronized high-speed bus and FlexRay timing.

Peripheral integration centers on time-triggered determinism: GTM provides autonomous I/O signal processing, MultiCAN+ supports 128 message objects with FIFO buffering, and ETH supports IEEE 802.3 with MII/RMII PHY interfaces - all managed through a 64-bit SRI crossbar enabling concurrent CPU, DMA, and peripheral access without arbitration delay.

FAQ

What is the maximum ambient temperature rating for SAK-TC234LP-16F200F AC?

The device is qualified per AEC-Q100 Grade 1, supporting continuous operation from −40 °C to +125 °C ambient temperature. Junction temperature limits are defined by thermal design - the PG-TQFP-144-27 package has a θ_JA of 32 °C/W, requiring minimum 4-layer PCB with thermal vias under the exposed pad for sustained 200 MHz operation at max ambient.

Does SAK-TC234LP-16F200F AC include hardware cryptographic acceleration?

Yes - when configured with the optional Hardware Security Module (HSM), it provides dedicated AES-128/256, SHA-256, and RSA-2048 acceleration, secure key storage, and tamper-resistant boot authentication. The HSM operates independently of the main TriCore cores and is accessible only via secure mailbox interfaces defined in the HSM specification.

How many CAN message objects does the MultiCAN+ module support?

The device integrates two MultiCAN+ modules, each supporting three CAN nodes (total six nodes) and up to 128 freely assignable message objects. These are organized into FIFO buffers and linked lists, enabling hardware-accelerated message filtering, timestamping, and gateway forwarding without CPU intervention - critical for high-load automotive networks.

Is external RAM required for SAK-TC234LP-16F200F AC operation?

No - the device contains 512 KB of on-chip EMEM (embedded memory), 32 KB LMU, and multiple scratchpad RAM banks (up to 184 KB DSPR). All internal memories feature ECC protection and are sufficient for full ASIL-D runtime execution, eliminating need for external RAM in most automotive ECU designs unless extended buffer space is required for logging or OTA staging.
