About

About AURIX TC48x microcontrollers

For applications like mainstream zone/domain controllers, gateways, entry chassis domain controllers, OEM‑customizable braking, and high‑performance camera monitoring, AURIX TC48x extends the AURIX TC4x family with dependable real‑time compute and broad connectivity. For such use‑cases TC48x combines 4/4 lockstep TriCore CPUs up to 400 MHz with the Cybersecurity Realtime Module (CSRM) and distributed Crypto Satellites (CSS) to safeguard critical functions and enable robust software isolation.

For connectivity applications like zonal controllers and gateways, TC48x offers features for improved data routing and integration of functions from end‑point ECUs. The optimized architecture sustains high throughput without main‑core intervention through the Data Routing Engine (DRE) and Ethernet bridging—helping teams consolidate more features on one ECU and accelerate delivery from concept to series production.

AURIX™ TC48x features
  1. Deterministic local memory architecture for fast real‑time data access
  2. Hardware data‑routing: DRE and Ethernet bridges for low‑overhead throughput
  3. CSRM: cybersecurity real‑time module with dedicated resources and crypto engines
  4. CSS: distributed crypto and hash offload for secure CAN/Ethernet communication
  5. Backward‑compatible software platform with AURIX TC3x MCUs
  6. Strong tools and partner ecosystem (AUTOSAR MCAL, drivers, safety/security packages)
AURIX™ TC48x Safety & Security and Audio features

AURIX TC48x Safety & Security

- Safety architecture aligned with ISO 26262 and ASIL‑D capable for zonal, gateway, and chassis domain controllers.

- Cybersecurity built on the CSRM module with distributed Crypto Satellites (CSS) to harden secure boot, comms, and key management across CAN/Ethernet.

AURIX TC48x Audio

The AURIX TC4x family includes TC48x devices with integrated audio connectivity and processing for automotive use. TC48x provides up to 3 TDM/I2S interfaces with mixer and sample‑rate converter (SRC) instances, a dedicated audio PLL for clock generation, and subsystem fabric that supports local DMA routing and access protection. On selected devices, media clock synchronization via TSN can be leveraged to align distributed audio streams in zonal architectures.

Designed for ADAS and vehicle platforms, TC48x enables acoustic-environment sensing and road‑condition analysis, integrates AVAS and active noise cancellation in EVs, and reduces speaker‑cable complexity for infotainment and telematics. It also supports in‑cabin communication, audio zones, telematics microphone arrays, and eCall connections—bringing a comprehensive audio solution to the AURIX TC4x portfolio.
