• Graphics Acceleration – Integrated graphics acceleration to support GUI and display tasks.
• Power & I/O – I/O voltage: 3.3 V.
• Package & Temperature – 289-LFBGA (14×14) surface-mount package rated for industrial grade operation from −40 °C to 85 °C.
• Compliance – RoHS compliant.

Typical Applications

• Industrial HMI – Drives LCD and touchscreen interfaces while handling user input from keyboards in industrial control panels.
• Embedded Networking Devices – Provides Ethernet and USB connectivity for networked embedded systems requiring moderate processing and secure communications.
• Secure Edge Controllers – Implements secure boot and cryptography features for edge devices that require protected operation and secure storage.
• Multimedia Interfaces – Uses NEON™ MPE and graphics acceleration for devices that require multimedia processing and display capabilities.

Unique Advantages

• Integrated Security Suite: Built-in ARM TrustZone plus multiple secure features (boot security, cryptography, secure JTAG/memory/RTC) to reduce external security components.
• Flexible Memory Options: Support for LPDDR1/2/3, DDR2/3/3L and QSPI enables designers to choose cost and performance trade-offs without changing the MPU.
• Display and UI Integration: On-chip controllers for keyboard, LCD and touchscreen simplify HMI designs and lower BOM count.
• Industrial Temperature Rating: −40 °C to 85 °C operation and industrial grade classification for reliable deployment in demanding environments.
• Compact Surface-Mount Package: 289-LFBGA (14×14) provides a compact footprint for space-constrained embedded boards.
• Standards-Based Connectivity: 10/100 Mbps Ethernet and USB 2.0 + HSIC support common connectivity needs without additional bridge devices.
