SAL-TC298TP-128F300N 概述
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory, and programmable peripherals. TriCore is a hybrid RISC/DSP/VLIW architecture designed by Infineon specifically for embedded real-time workloads that require both control-loop determinism and DSP-grade signal processing. Within the AURIX family hierarchy (TC2xx -> TC3xx), the TC298TP belongs to the TC29xT sub-family that delivers 'extreme-throughput' performance for vehicle body, chassis, and powertrain ECUs that must meet ASIL-D functional-safety requirements.
Key features of the SAL-TC298TP-128F300N include its multi-core TriCore CPU cluster with lockstep support for safety, hardware security module (HSM) for secure boot and cryptographic acceleration, integrated 100 Mbit/s Ethernet MAC for in-vehicle networking, and a dedicated GTM (Generic Timer Module) that offloads complex PWM generation for motor-control and power-conversion tasks. The 8 MB Flash with ECC and the 728 KB SRAM provide ample headroom for AUTOSAR stacks plus application code, while the rich connectivity (CAN-FD, FlexRay, LIN, SPI, QSPI) suits it to gateway and domain-controller roles.
Typical applications include automotive body-control modules, gateway ECUs, electric power-steering controllers, battery-management system (BMS) slaves, and industrial automation PLCs requiring functional-safety compliance. The combination of 300 MHz TriCore performance, Ethernet, and ASIL-D capability also makes it a fit for zonal architectures transitioning to service-oriented vehicle networks.
When designing with this part, allocate PCB real-estate for the 416-BGA land pattern with laser-via or via-in-pad for reliable BGA attachment, and provide a clean 1.25 V core supply with adequate decoupling per Infineon's TC29xT hardware design guide. Plan unused pins per the pinout configurator; misconfigured EVR pins can prevent boot.

典型应用
SAL-TC298TP-128F300N 适用于 6 应用s: Automotive Body Control Module (BCM), Vehicle Gateway / Zonal ECU, Electric Power Steering (EPS) Controller, Battery Management System (BMS) Slave Controller, Industrial Servo Drive / Motion Controller, Domain Controller / Cockpit Host.
Automotive Body Control Module (BCM)
The SAL-TC298TP-128F300N suits body-control modules that drive lighting, wipers, mirrors, and door-lock actuators because it combines 300 MHz TriCore performance with 6 CAN-FD nodes and ASIL-D capability for safety-relevant body functions like indicator lamps. The 21 ADC channels digitize ambient-light, battery-sense, and motor-current signals directly without an external ADC. Per Infineon's AURIX BCM reference designs, the part's lockstep core plus HSM satisfies the OEM's secure-boot mandate while the 100 Mbit Ethernet MAC feeds diagnostic data over DoIP.
推荐
Vehicle Gateway / Zonal ECU
The SAL-TC298TP-128F300N's 100 Mbit/s Ethernet MAC, FlexRay, and 6 CAN-FD nodes allow it to bridge legacy in-vehicle networks (CAN, LIN, FlexRay) with automotive Ethernet backbones in a zonal or central gateway ECU. The 728 KB SRAM buffers routing tables and security keys, while the 8 MB Flash holds the full AUTOSAR RTE plus communication stacks. Compared with a TC3xx part, the TC298TP trades raw headroom for cost-effectiveness in mid-complexity gateways.
推荐
Electric Power Steering (EPS) Controller
EPS controllers need deterministic torque-loop execution and ASIL-D capability, both delivered by the SAL-TC298TP-128F300N's lockstep TriCore cores running at 300 MHz. The GTM (Generic Timer Module) generates the PWM signals for the three-phase BLDC torque motor with sub-microsecond resolution, and the 21 ADC channels sample phase currents, rotor position, and torque-sensor signals simultaneously. Infineon AURIX TC2xx is the de-facto standard for EPS, so a wealth of validated AUTOSAR software components is available.
推荐
Battery Management System (BMS) Slave Controller
In a distributed BMS, each slave module monitors cell voltages and temperatures and reports over CAN-FD or isolated SPI to the master; the SAL-TC298TP-128F300N handles 12-18 cells with its 21 ADC inputs and provides the ASIL-D diagnostic coverage mandated for traction batteries. The 8 MB Flash holds cell-balancing firmware plus the BMS state-machine, and the Ethernet MAC enables faster daisy-chained BMS topologies. The lockstep CPU catches faults in the measurement path before they affect SoC calculations.
推荐
Industrial Servo Drive / Motion Controller
Industrial servo drives require deterministic PWM generation, fast current-sense sampling, and EtherCAT or CANopen connectivity - all delivered by the SAL-TC298TP-128F300N's TriCore, GTM, and rich communication peripherals. The 300 MHz headroom runs the control loop, the trajectory planner, and the safety stop function in parallel cores. Compared with a generic ARM Cortex-M4 MCU, the TC298TP offers the lockstep dual-core for SIL-2/SIL-3 industrial safety, removing the need for an external safety MCU.
推荐
Domain Controller / Cockpit Host
Higher-end cockpit and ADAS domain controllers may use the SAL-TC298TP-128F300N as a sensor-fusion preprocessor or as a secure gateway to higher-power SoCs. The 8 MB Flash and 728 KB SRAM fit lightweight RTOS plus driver-assistance algorithms (sensor clustering, object pre-filtering), while the HSM secures the boot chain and OTA updates. Although not as compute-dense as the TC3xx or AURIX TC4xx families, the TC298TP delivers a cost-effective compute tier for entry-level domain controllers.

关键差异点
- TriCore architecture with lockstep core for ASIL-D （对比 ARM Cortex-M4F automotive MCUs (e.g., SPC58, S32K3))
- Integrated 100 Mbit Ethernet MAC vs. external PHY-only on TC2xx lower-tier （对比 Infineon TC27x TP family (e.g., TC275TP))
- Hardware Security Module (HSM) with EVITA-Full support （对比 SAF-XC2000 family (older C166-based MCUs))
设计说明
The 416-ball BGA of the SAL-TC298TP-128F300N typically uses a 0.8 mm pitch. For reliable attachment use laser-via or via-in-pad technology with filled-and-capped vias under the BGA. Provide a 4-layer PCB minimum with continuous GND planes on layers 2 and 4 to give the EVR and ADC references a low-impedance return path. Recommended: per-pin decoupling 100 nF X7R + 4.7 uF X5R within 2 mm of each power/ground ball pair, and one 10 uF bulk per power domain. Follow Infineon's TC29xT HW Design Guide for ball-specific supply sequencing.
Estimated: at 300 MHz across both TriCore cores with peripherals active, the SAL-TC298TP-128F300N dissipates approximately 1.5-2.5 W typical. The 416-BGA exposed-die package relies on PCB copper for cooling - provide at least 25 x 25 mm of unbroken copper on the top layer plus thermal vias to inner GND planes. For under-hood or EPS applications where ambient can exceed 85 C, simulate junction temperature with the Infineon thermal model before committing to PCB stack-up. Thermal derating above 105 C junction follows the datasheet curve.
Common pitfalls when bringing up the SAL-TC298TP-128F300N: (1) Confusing the SAL- prefix with the SAK- prefix - both refer to the same silicon but different distribution channels; SAK is sample-tier and SAL is commercial-volume. (2) Forgetting to configure the EVR (Embedded Voltage Regulator) mode in the boot pins - a wrong mode prevents core voltage ramp. (3) Mixing TC298TP and TC299TP datasheets; pinout of the 416-BGA (TC298TP) is NOT compatible with the 516-LFBGA (TC299TP). (4) Not enabling the HSM before secure boot will silently fail in production but pass on the bench.
For the 100 Mbit/s Ethernet MAC routing, use 50 ohm single-ended controlled-impedance traces (100 ohm differential) on the MII/RMII/RGMII bus to the external PHY. Keep trace lengths matched within 50 mil on the parallel interface and isolate the analog PHY clocks from switching DC-DC nodes. The FlexRay signals are differential and require 100 ohm termination at both ends; route them on a stripline layer with continuous GND reference. Use IBIS-AMI simulation for the Ethernet MAC-PHY channel before committing to PCB layout.
