The MPU features extensive connectivity and security, and is intended for smart infrastructure, manufacturing automation, and new energy systems requiring control and networking.
The device is based around the dual power-efficient high-performance 64/32-bit Arm Cortex-A35 cores (Armv8-A architecture), running at up to 650 MHz, with 32KB of L1 instruction and data cache for each core, plus a 512KB shared L2 cache.
The MA35D0 also features high-performance hardware floating-point units (FPU) that enhance its digital signal processing (DSP) capabilities.
The MA35D0’s LQFP package, with 128MB or 256MB of stacked DDR SDRAM, has been designed to significantly reduce PCB layer count, device size, BOM cost, and electromagnetic interference (EMI). The chip has an extensive operating temperature (Tj) range from -40°C to +125°C, and so can provide reliable operation even in challenging edge computing environments.
The MA35D0 series can establish fast encrypted communications, keep sensitive user data safe, and can offer a secure environment for critical applications. The MPU supports secure booting in four modes: USB, SD/eMMC, NAND, and SPI Flash (SPI NOR/SPI NAND).
This chip provides a trusted system that meets the practical security requirements of industrial applications. Arm TrustZone secure boot, and other security features help this MPU safeguard valuable data and code. In addition to TrustZone, it includes Snoop Control Unit (SCU) L2 cache protection and built-in cryptographic accelerators with AES, SHA, ECC, RSA, SM2/3/4 - plus a True Random Number Generator (TRNG). The MPU’s cryptographic key store and OTP memory further protect sensitive data.
For high-performance edge device roles, such as industrial control or gateway applications, the MA35D0 series provides high-speed connectivity and advanced control interfaces, such as 2x megabit ethernet (complying with IEEE 1588 v2), high-speed USB host and device connections, SD3.0/eMMC, 3x CAN FD, and 11x UART.
The MA35D0 series also provides touchscreen support and a TFT LCD controller, with resolutions up to 1280x800.
Nuvoton provides an extensive evaluation and development system, the MA35D0 EVB, which is pre-loaded with remote control examples, such as browser status access and cloud connectivity, allowing users to begin evaluation and development immediately.
