• Memory and Cache – Integrated MMU with 32 KB L1 data cache, 32 KB L1 instruction cache and configurable 128 KB L2 cache; supports LPDDR1/2/3, DDR2/3/3L and QSPI Flash interfaces.
• Integrated SRAM/ROM – Includes internal scrambled SRAM and multiple ROM regions for bootloader and BCH ECC support as documented in the series datasheet.
• Peripherals and Timers – Rich system peripherals including DMA (51 channels), advanced interrupt controllers, reset/shutdown controllers, watchdog timers and a secure real-time clock.
• Display and Imaging – LCD/TFT controller supporting up to 1024×768 with overlays, rotation and alpha blending; Image Sensor Controller (ISC) supporting up to 5 MP sensors with 12-bit parallel interface.
• Connectivity – 10/100 Mbps Ethernet (1), USB 2.0 with HSIC support, CAN (series datasheet), I2C and multiple serial audio and synchronous interfaces.
• Security – Hardware security features including ARM TrustZone, boot security, AES/SHA crypto engines, TRNG, secure fusebox, secure JTAG, secure memory and secure RTC.
• Low-Power and Clocking – Ultra-low-power modes with fast wakeup, backup modes with SRAM, multiple PLLs including system and USB PLLs, and selectable low-frequency oscillators.
• Package and Environmental – 289-LFBGA (14×14) surface-mount package; industrial operating temperature range of –40 °C to 105 °C; RoHS compliant.

Typical Applications

• Human‑Machine Interfaces (HMIs) – Use the integrated LCD/TFT controller, touchscreen support and graphics acceleration for responsive operator panels and graphical displays.
• Embedded Connectivity Devices – Leverage Ethernet, USB 2.0 and multiple serial interfaces for networked gateways, protocol bridges and communication modules.
• Secure IoT and Edge Nodes – On-chip cryptography, TrustZone and secure storage enable secure boot and protected data handling for connected edge devices.
• Imaging and Vision Peripherals – Image Sensor Controller and multimedia processing support camera interfaces and basic image preprocessing for vision-enabled products.

Unique Advantages

• High integration reduces BOM – Combines CPU, memory controllers, display, imaging and connectivity peripherals in one device to simplify board design and lower component count.
• Security built into hardware – Multiple secure elements (TrustZone, crypto engines, secure fusebox/JTAG and secure RTC) streamline implementation of protected boot and secure storage.
• Flexible memory support – Native controllers for DDR2/DDR3/DDR3L, LPDDR variants and QSPI Flash provide designers with broad memory choices for cost and performance trade-offs.
• Designed for low-power embedded use – Ultra-low-power modes, fast wakeup and backup SRAM options support energy-conscious applications with intermittent activity.
• Industrial temperature range – Rated for –40 °C to 105 °C operation to meet environmental demands of industrial and harsh-environment systems.
