• Memory & Storage Interfaces Flexible memory controller support for LPDDR1, LPDDR2, LPDDR3, DDR2, DDR3, DDR3L and QSPI for a range of external memory and NOR/NAND storage options.
• Connectivity & Peripherals Integrated single 10/100 Mbps Ethernet interface, USB 2.0 with HSIC, and I²C support to handle common wired communications and sensor interfaces.
• Display & HMI Display interface controllers for keyboard, LCD and touchscreen enable compact human‑machine interface implementations and local user control.
• Security & System Integrity Hardware security features including ARM TrustZone (ARM TZ), boot security, cryptography, RTIC, secure fusebox, secure JTAG, secure memory and secure RTC to protect boot and runtime operations.
• Graphics Acceleration On‑chip graphics acceleration to offload UI rendering and improve responsiveness for display‑centric applications.
• Power & I/O 3.3 V I/O signaling and surface‑mount 289‑LFBGA package simplify integration into standard embedded boards.
• Industrial Grade Rated for operation from -40 °C to 105 °C to meet the temperature demands of industrial environments.

Typical Applications

• Human‑Machine Interfaces (HMI) On‑board LCD and touchscreen controllers plus graphics acceleration enable responsive local user interfaces and control panels.
• Industrial Embedded Systems Industrial temperature rating and extensive security features make it suitable for control equipment and secure embedded controllers.
• Networked Devices Integrated 10/100 Mbps Ethernet and USB 2.0 with HSIC support enable connectivity for communication and peripheral attachment.
• Secure Appliance Controllers Boot security, cryptography and secure storage features support secure boot and protected runtime for connected appliances and instrumentation.

Unique Advantages

• Balanced processing and media acceleration: 500 MHz Cortex‑A5 core with multimedia DSP and NEON™ MPE offloads media and signal tasks while preserving control responsiveness.
• Broad memory compatibility: Supports LPDDR1/2/3, DDR2/3/3L and QSPI to match a wide range of external memory choices and cost targets.
• Comprehensive onboard security: Multiple hardware security primitives (TrustZone, secure JTAG, secure fusebox, cryptography and secure RTC) reduce system-level integration effort for protected designs.
• Integrated connectivity: Single 10/100 Mbps Ethernet, USB 2.0 + HSIC and I²C provide essential network and peripheral interfaces without additional controllers.
• Industrial readiness: -40 °C to 105 °C operating range and a surface‑mount 289‑LFBGA package enable deployment in demanding embedded environments.
• HMI‑focused I/O: Dedicated controllers for keyboard, LCD and touchscreen simplify implementation of compact user interfaces.
