Product details
Overview
TC237L32F200SACLXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring a lockstepped TC1.6E CPU core operating up to 200 MHz, 2 MB program flash with ECC, 128 KB data flash for EEPROM emulation, and integrated IEEE 802.3 Ethernet MAC with RMII/MII interfaces. It targets automotive ADAS domain controllers requiring functional safety (ISO 26262 ASIL-D capable), real-time deterministic execution, and multi-protocol connectivity.
For engineers reviewing the TC237L32F200SACLXUMA1 datasheet, TC237L32F200SACLXUMA1 pinout, TC237L32F200SACLXUMA1 application, or TC237L32F200SACLXUMA1 equivalent, key selection criteria include dual-core lockstep configuration, on-chip HSM support, E-Ray v2.1 compliance, GTM-based I/O timing autonomy, and integrated Ethernet PHY interface readiness.
Technical Context
The TC237L32F200SACLXUMA1 implements a safety-critical dual-core architecture where the primary TC1.6E core executes application code while its shadow core performs lockstep comparison in real time, enabling detection of transient faults per ISO 26262 requirements. Its System PLL supports configurable clock tree distribution to CPU, peripherals, and bus subsystems.
It integrates a 64-bit SRI crossbar interconnect enabling concurrent access between CPU, DMA, GTM, and memory blocks, alongside an SPB peripheral bus for low-latency register access. The embedded voltage regulator (EVR) provides internal 1.3 V and 3.3 V domains with monitoring and reset generation on undervoltage conditions.

FAQ
What is the maximum ambient temperature rating for TC237L32F200SACLXUMA1?
The device is qualified for operation from –40 °C to +125 °C ambient temperature, validated per AEC-Q100 Grade 1 requirements. Junction temperature must remain below 150 °C under all operating conditions, with thermal design guidance provided in the package outline section (page 226) of the datasheet.
Does TC237L32F200SACLXUMA1 include hardware cryptographic acceleration?
No-the base TC237L32F200SACLXUMA1 variant does not integrate a Hardware Security Module (HSM). However, certain ordering options (e.g., TC237L32F200SACLXUMA2) include an optional HSM supporting AES-128/256, SHA-256, and RSA-2048 acceleration with secure key storage.
Can the Ethernet MAC operate in RMII mode without an external PHY?
No-the integrated Ethernet MAC requires an external PHY for physical layer signaling. RMII mode reduces pin count versus MII but still mandates external components including magnetics, 50 MHz reference clock, and PHY-level registers accessed via MDIO/MDC.
How many independent CAN FD channels does TC237L32F200SACLXUMA1 support?
It supports six CAN FD channels via two MultiCAN+ modules (each with three CAN nodes), with full CAN FD frame handling (up to 64-byte payloads), bit rates up to 5 Mbit/s, and hardware message filtering across 128 configurable message objects.
