Product details
Overview
SAK-TC233L-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 (EEPROM-emulated), and integrated Ethernet MAC (MII/RMII), dual MultiCAN+ (6 CAN nodes), and FlexRay v2.1. It targets automotive ADAS domain controllers requiring ASIL-D compliance and functional safety.
For engineers reviewing the SAK-TC233L-32F200N AC datasheet, SAK-TC233L-32F200N AC pinout, SAK-TC233L-32F200N AC application, or SAK-TC233L-32F200N AC equivalent, this page delivers verified technical context, package mapping to PG-TQFP-100-23, real-world use cases in vehicle networking and sensor fusion, and validated alternative parts for safety-critical ECU design.
Technical Context
The SAK-TC233L-32F200N AC implements a dual-core lockstep architecture where the shadow core continuously verifies the primary TC1.6E CPU's instruction execution-enabling hardware-level fault detection per ISO 26262 ASIL-D requirements. Its Safety Management Unit (SMU) monitors ECC errors, memory test unit (MTU) coverage, and I/O monitor (IOM) status.
It integrates a dedicated Hardware Security Module (HSM) option for secure boot and cryptographic acceleration (AES-128/256, SHA-256, RSA-2048), alongside a System PLL supporting 200 MHz core clock generation and an ERAY_PLL for independent FlexRay timing. The 64-bit SRI crossbar enables concurrent access between CPU, DMA, GTM, and peripherals without arbitration delay.

FAQ
What is the maximum operating temperature range for SAK-TC233L-32F200N AC?
The device 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 VADC, CAN, and Ethernet MAC-ensuring reliability in under-hood automotive environments.
Does SAK-TC233L-32F200N AC include hardware-based cryptographic acceleration?
Yes-the part includes an optional Hardware Security Module (HSM) supporting AES-128/256, SHA-256, and RSA-2048 operations. When enabled, the HSM handles secure boot, key derivation, and firmware signature verification independently of the main CPU, satisfying UNECE R155 CSMS requirements.
Can SAK-TC233L-32F200N AC support both MII and RMII Ethernet interfaces simultaneously?
No-it supports either MII or RMII mode via configuration of the ETH peripheral registers and corresponding pin multiplexing, but not both concurrently. RMII reduces pin count (6 pins vs. 16 for MII) and is typical for space-constrained gateways; MII offers full-duplex 100 Mbps with standard PHY compatibility.
Is the 128 KB DFLASH truly EEPROM-emulated, and what endurance does it provide?
Yes-the DFLASH implements wear-leveling and write-cycle management in firmware (via provided driver libraries) to emulate EEPROM behavior. It guarantees ≥100,000 write/erase cycles per sector and data retention of ≥10 years at 125 °C, validated per AEC-Q100 stress testing protocols.
