An AURIX (Automotive Realtime Integrated Next-gen Architecture) microcontroller is a multicore MCU family originally developed by Infineon targeting ASIL-D functional safety under ISO 26262. TriCore fuses RISC, DSP, and microcontroller instruction-set concepts into one architecture, allowing deterministic interrupt response together with signal-processing throughput. Within the AURIX TC2 hierarchy, the TC23xL sits below TC26x and TC27x — fewer cores and less peripherals, but the same safety concept (lockstep, MPU, ECC) and the same toolchain (Aurix Development Studio, HighTec/GCC). This hierarchy makes the TC23xL a popular step-down choice when a TC26x design is over-budget.
Key device features include 2 MB Program Flash, 192 KB SRAM with ECC, a 200 MHz TriCore DSP core, on-chip CAN-FD nodes, ASIL-B/D hardware support via lockstep and ECC, and a -40C to +125C (or +150C) automotive operating range. The TC23xL retains the AURIX safety and security story with a smaller die, enabling designs that must hit cost targets while still meeting ISO 26262 requirements at ASIL-B or split-lock ASIL-D.
Architecturally, the TC233LP single-core variant routes DMA, timing, and interrupt traffic through the AURIX SPB (System Peripheral Bus), with safety primitives like End-to-End ECC on Flash and dedicated memory protection. Compared with TC26x (TC26xB) and TC27x (TC27xB/TC27xD) devices, the TC233LP trims memory and removes one CPU while keeping the safety DNA, which is what makes it attractive for body-domain controllers and entry-level domain ECUs where higher-end AURIX would be over-spec.
Typical applications include automotive body controllers, BCM (Body Control Modules), gateway ECUs, chassis sensor nodes, and entry-level domain ECUs where ASIL-B / ASIL-D split-lock compliance is required. The TC233LP is also used in BMS slaves and EV charging controllers that need deterministic communication and a proven automotive toolchain.
When migrating software from TC26x to TC23xL, confirm that the consumed peripheral set (number of CAN-FD nodes, QSPI channels, HSM presence) maps to TC23xL availability — TC23xL parts like the SAK-TC233LP-32F200N intentionally remove some peripherals to reach lower-cost power classes. Use Infineon's TC23xL datasheet and target hardware manual before finalizing the BOM.

典型應用
SAK-TC233LP-32F200N 適用於 6 應用s: Automotive Body Control Module (BCM), Vehicle Gateway ECU, EV Battery Management Slave/BMS Node, Chassis Sensor Nodes / Suspension ECU, Industrial / Robotics Functional-Safety PLC, DC Fast Charging / EV Charging Station Controller.
Automotive Body Control Module (BCM)
The SAK-TC233LP-32F200N is well matched to entry-level body control modules: a single TriCore v1.6.1 core at 200 MHz executes LIN/CAN-FD stacks, lighting/wiper/window logic, and PWM control loops concurrently, while 2 MB Flash absorbs full BCM application plus bootloader/A/B slots. The TC233LP's ASIL-B capability under ISO 26262 covers BCM safety goals such as rear-light failure detection without dragging in extra TC26x cores. Placed as the BCM master, it cuts the headroom that a TC27x would leave on the table and reuses the same Aurix toolchain and SPB peripheral set. Trade-off: BCM designs that need HSM or complex ASIL-D safety on more than one channel should step up to TC26x/TC27x.
推薦
Vehicle Gateway ECU
The SAK-TC233LP-32F200N targets compact automotive gateway ECUs that bridge CAN-FD segments and aggregate chassis/body data. Its multi-M_CAN nodes plus 2 MB Flash let the device host routing tables, network management, security filtering, and partial OTA staging, all on one chip. The 200 MHz TriCore runs AUTOSAR Classic stacks with cycle budgets typical of CAN-FD at 5 Mbit/s, while the ECC-protected Flash supports safe B-slot firmware swaps. For high-throughput central gateways, designers move to TC26x (TC265) and TC27x (TC275); the TC233LP wins on gateway designs that need <100 Mbps total CAN throughput and prefer a smaller die/BOM. PCB layout reuses TQFP-100 land pattern across LP/F variants, supporting late-stage BOM changes.
推薦
EV Battery Management Slave/BMS Node
In EV/HEV battery management the SAK-TC233LP-32F200N sits at cell-monitoring slaves or 12V battery sensor nodes where deterministic time response and ASIL-B safety are non-negotiable. The TriCore DSP engine performs coulomb counting and cell-balancing math at 200 MHz, while the 2 MB Flash stores balancing tables, aging curves, and CAN-FD diagnostic logs. The TC233LP's ECC on Flash and SRAM catches single-bit faults that would corrupt balancing SOC estimates, which is critical for ISO 26262 ASIL-B at the BMS slave level. Compared with a generic Cortex-M4 MCU, the AURIX offloads security and CAN-FD off-chip. For master BMS controllers that aggregate 96+ cells and need HSM, designers step up to TC27x. The TQFP-100 footprint allows rapid transition between LP/F suffixes within the same BMS hardware design.
推薦
Chassis Sensor Nodes / Suspension ECU
The SAK-TC233LP-32F200N fits mid-tier chassis sensor nodes such as steering-angle sensors, wheel-speed aggregators, and suspension actuators where 200 MHz and ASIL-B capability matter. Its locked-step peripherals and ECC on Flash/SRAM let the chassis functions meet split-lock ASIL-D together with a second TC23x. The 2 MB Flash covers chassis signal processing firmware plus sensor calibration tables; CAN-FD moves real-time state to the central chassis domain controller over the standard vehicle bus. Compared with a low-end microcontroller, the AURIX adds deterministic DSP extension for active suspension math. Designers sometimes drop to TC233L or TC233P (smaller Flash) for simple sensor nodes. The TQFP-100 is appropriate for chassis-mounted PCBAs with exposed thermal pad for hot-floor testing.
推薦
Industrial / Robotics Functional-Safety PLC
Outside automotive, the SAK-TC233LP-32F200N supports industrial functional-safety controllers and small robotics PLCs that benefit from a deterministic 32-bit TriCore core and a TQFP-100 footprint, while keeping an automotive-grade ASIL-B story. The 2 MB Flash hosts IEC 61131-3 runtimes plus application logic for motor control, while CAN-FD and ASIL-B safety primitives help certify industrial machinery to IEC 61508 SIL-2/SIL-3. The AURIX safety library (SMU, Lockstep, ECC) is documented in the TC23xL User's Manual and aids CE machinery certification. Compared with a Cortex-R or Cortex-M microcontroller, the TriCore adds DSP extension for control-loop math. For high-end robotics nodes that need multi-axis control, designers usually move to TC26x or TC27x (dual/triple core).
推薦
DC Fast Charging / EV Charging Station Controller
The SAK-TC233LP-32F200N is suitable as a primary controller in DC fast charging station sub-modules where ISO 26262-derived safety CAN-FD communication, lockstep, and ECC are equally valuable in non-automotive settings. The single 200 MHz TriCore handles OCPP ↔ PLC ↔ power-module bridging, isolation monitoring, and authentication logic, while 2 MB Flash stores charging curves and remote firmware. The TC233LP family is widely deployed in modular EV charging controllers because of its deterministic interrupt response and 5 V-tolerant GPIOs that interface to industry-standard analog front ends. For higher-power 350 kW chargers with parallel modules, designers often twin two TC26x CPUs. The TQFP-100 footprint and Infineon toolchain shorten time to UL/IEC certification.

主要差異化特點
- Single-core AURIX TC23xL with built-in lockstep support (對比SAK-TC233L-32F200N)
- CAN-FD / ISO 11898-1 support present on N-suffix (對比SAK-TC233LP-32F200F)
- Lower peripheral count and lower cost than TC234L (對比SAK-TC234L-32F200N)
設計說明
The SAK-TC233LP-32F200N has multiple supply rails (V_EXT for 5V/3.3V IO, V_EVR+/V_EVR- for the internal EVR switching stage, V_ADCx reference pins for the ADCs, V_BAT/V_RTC for RTC, and V_HSIF/V_FLEX for high-speed serial). Decouple each adjacent supply pin with at least 100 nF ceramic plus bulk 1 uF + 4.7 uF; the EVR driver return pin V_EVR- must be kelvined to the ground plane directly under the package to prevent switching noise from coupling into ADC references. V_SSEN must be tied in a star to V_SS at the package ground paddle.
The PG-TQFP-100-23 has an exposed thermal/ep pad (footprint name 23) which must be soldered to a continuous copper plane on the top layer. In automotive underhood environments, ambient of +125C and BCM current draw around 200-400 mA push junction temperature close to the 150C limit; a thermal copper pour of 1 square inch or more is needed. Use the Infineon AURIX TC23xL thermal model from the User's Manual to estimate theta_JA (~25 C/W with proper copper) and leave margin per ISO 16750 load-dump transients.
Estimated: assuming typical BCM task load at 200 MHz, the SAK-TC233LP-32F200N executes ~150-200 MIPS. Do NOT route the EVR switching currents through the digital ground; use the EVR ground plane per the Infineon AURIX TC2xx hardware design guide. When starting up, V_EXT must rise above the Power-On Reset threshold before any I/O toggles; otherwise the SMU will flag a cold-POR. Always connect V_BAT to a backup battery or supercap if you need RTC retention across cranking profiles.
Place 100 nF bypass capacitors within 1-2 mm of every V_EXT, V_EVR, V_ADC supply pin. The two V_EXT pins and multiple V_SS pins must be stitched with multiple vias into the same ground and power planes. The ADC analog ground (V_SSEN) and digital ground (V_SS) should be joined only at a single point near the chip. For CAN-FD and HSCT routing, observe the 50 ohm impedance for those pairs; for crystal traces (XIN/XOUT) keep the lines short, symmetric, and guarded by a ground ring to suppress spurious modes.
