• Multimedia and Graphics  Integrated graphics acceleration with an LCD/TFT controller and touchscreen support plus an image sensor controller and audio interfaces (I2S, SSC, stereo Class D amplifier, digital microphone) for rich user interfaces.
• Connectivity  On-chip 10/100 Mbps Ethernet (1), multiple USB ports including HSIC, two QSPI controllers, SDIO/SD/e.MMC interfaces, CAN-FD, UARTs, SPIs, FLEXCOMs and TWI/I2C for extensive I/O options.
• Security and Safe Boot  Hardware security set including AES, SHA, TDES, TRNG, ARM TrustZone®, Secure JTAG, secure memory and boot security with Integrity Check Monitor and support for encrypted code execution.
• DMA and Event System  Internal multilayer bus with DMA support (including 2×16 channels and dedicated DMAs) plus an event system that lets peripherals interact without processor intervention.
• Low-Power Modes  Multiple software-selectable low-power modes: Idle, Ultra-Low-Power (two levels) and Backup with RTC and optional DDR self-refresh to minimize standby power.
• Package and Environmental  289‑LFBGA (14×14) surface-mount package with operating temperature range of −40°C to 105°C; RoHS compliant.

Typical Applications

• Industrial Control  Secure processing and connectivity for embedded controllers, leveraging the industrial grade package and broad I/O set.
• Human–Machine Interfaces (HMI)  LCD/TFT, touchscreen, graphics acceleration and audio support enable responsive operator displays and multimedia GUIs.
• Secure IoT Gateways and Edge Devices  On-chip cryptographic engines, TrustZone and secure boot capabilities support device authentication, data protection and secure communications.
• Imaging and Audio Processing  NEON multimedia engine, FPU and an image sensor controller provide on-board acceleration for vision and audio capture tasks.

Unique Advantages

• Highly integrated peripheral set: Reduces BOM and board complexity by combining Ethernet, USB, CAN‑FD, QSPI, SD/e.MMC and multiple serial interfaces on-chip.
• Security-focused architecture: Hardware crypto accelerators, TrustZone, secure JTAG and boot protection help protect code and data at runtime and during boot.
• Flexible memory support: Wide support for DDR2/DDR3/DDR3L/LPDDRx and multiple flash options enables adaptable memory subsystem designs.
• Power management versatility: Multiple low-power modes and DDR self-refresh options allow designs to optimize power for active and standby scenarios.
• Industrial temperature and packaging: −40°C to 105°C operating range in a 289‑LFBGA surface-mount package suits demanding environments.
• Software and ecosystem support: Delivered with AutoSAR MCAL libraries and with vendor-supported Linux distribution, EGT, Harmony and MPLAB‑X support to accelerate development.
