Atmel Corporation has introduced the Atmel SAMA5D3 ARM Cortex-A5 microprocessor series, its highest performance, low-power microprocessor. The new SAMA5D3 series targets industrial applications, including factory and building automation, smart grid, medical and handheld terminals, along with consumer applications such as smart watches, outdoor GPS, DECT (digital enhanced cordless telecommunications) phones.
The Cortex-A5 core is the most efficient core of the Cortex-A family. The Cortex-A5 is a subset of the Cortex-A9. The Atmel SAMA5D3 is targeting ARM9 and ARM11 users. Atmel boasts it has the best performance for it's power consumption, making it the most efficient Cortex-A core. Also, it has a real cool Linux demo board.
The Atmel SAMA5D3 can run as up to 536MHz. It requires less than 0.5mW in Low-power mode, less than 200mW when running like mad at 536MHz.
Atmel is making a 12-year lifetime commitment to this device. So use it with confidence.
The SAMA5D3 product embeds one 160-Kbyte internal ROM containing a standard and a secure bootloader. The secure bootloader is described in a separate document, under NDA. The standard bootloader supports booting from the 8-bit NAND Flash with ECC management, SPI Serial Flash, SDCARD, EMMC, or TWI EEPROM. The boot sequence can be selected using the boot order facility (Boot Select Control Register). The internal ROM embeds Galois field tables that are used to compute NandFlash. What all this means is that the SAMA5D3 provides excellent protection against anti-cloning.
