SAK-TC234LP-32F200N Descripción general
A 32-bit microcontroller (MCU) is an integrated processor that combines a CPU core, memory, and programmable peripherals on a single silicon die. Within the embedded hierarchy, a TriCore AURIX MCU sits between a generic microcontroller and a microprocessor SoC, combining real-time control performance with DSP capability and on-chip safety features. The AURIX family in particular targets automotive functional-safety applications under ISO 26262, integrating lockstep cores and hardware security modules.
Key features include 32-bit single-precision performance at 200 MHz, 2 MB program Flash, 128 KB Data Flash plus 192 KB SRAM, a six-node CAN/CAN-FD interface, and 24 ADC input channels. The TQFP-144 (16x16 mm) package with exposed pad provides efficient thermal dissipation for automotive under-hood and chassis applications.
The TC23xL architecture combines one TriCore CPU with dedicated peripheral subsystem and on-chip debug support, enabling deterministic interrupt response. Its lockstep-aware design supports ASIL-B/D safety classification, while the on-chip HSM provides cryptographic acceleration for secure boot and OTA updates.
Typical applications include automotive body and chassis ECUs, electric power steering, airbag controllers, sensor fusion nodes, and safety-critical industrial PLCs. The wide 1.17V-5.5V supply range also supports 12V/24V battery-direct designs without external regulators.
When designing with this device, ensure the exposed thermal pad is soldered to a sufficiently large copper pour to meet the datasheet thermal resistance specification. The CAN-FD support differentiates the -32F200N variant from the -32F200F revision; verify peripheral requirements before substituting.
This page synthesizes distributor pricing, AURIX family cross-references, and practical design notes not found in the manufacturer datasheet, giving engineers a single reference for cost-down and second-source decisions.

Notas de diseño
Estimated: At continuous 200 MHz operation with internal core voltage ~1.3 V and I/O switching at 5 V, the SAK-TC234LP-32F200N AC dissipates approximately 0.8-1.2 W depending on peripheral activity. Solder the exposed thermal pad of the TQFP-144 to at least 200 mm^2 of copper pour (4-layer board recommended) to keep the junction temperature below 150 C at the 125 C ambient rating; an insufficient thermal pad connection is the most common cause of AURIX field failures.
The 1.17 V to 5.5 V supply input tolerates direct 12 V automotive battery connection only through an external pre-regulator (e.g., Infineon TLE8366 buck). Use a 100 nF X7R decoupling capacitor within 2 mm of each VDD pin and a 4.7 uF bulk capacitor on the VEXT supply rail. Adding a 10 uF tantalum hold-up capacitor on VBAT prevents MCU resets during cranking transients down to 6 V.
Route the six CAN-FD differential pairs as 100 ohm impedance-controlled microstrip with matched length within 5 mm. Keep the oscillator traces (XTAL1/XTAL2) shorter than 10 mm and shield them with a ground guard ring to prevent EMI coupling into the ADC inputs. The exposed pad of the TQFP-144 must have at least 8 thermal vias (0.3 mm drill, 0.5 mm pitch) to inner ground planes for heat extraction.
Do not confuse the SAK-TC234LP-32F200N AC (CAN-FD supported) with the SAK-TC234L-32F200F AC (classic CAN only); pinout is identical but firmware CAN driver configuration differs. Also, ensure that the OPTIGA HSM is provisioned with OEM-provisioned keys before first power-up if secure boot is required - field returns often stem from missing HSM personalization.
The 24 ADC input lines are multiplexed with timer capture inputs; route analog signals away from switching power and CAN traces to avoid coupling. For ADC accuracy better than 8 ENOB at full sampling rate, place a 100 nF X7R bypass on each analog supply pin (VDDA) and use a separate analog ground island connected to the MCU AGND pin at a single point.
