Microchip Technology

The AT91SAM7XC512B is functionally and mechanically equivalent to the AT91SAM7X512B with the addition of AES/TDES crypto processors. These peripherals must be initialized before use, so if the user code does not configure these peripherals, the device will function similarly to the non-crypto version. Please refer to the documentation below for updated programming requirements when migrating from the AT91SAM7X512 device to the AT91SAM7X**C**512 device. The Microchip ARM-based SAM7X512 is a member of the Microchip SAM7X series of microcontrollers based on the 32-bit ARM7TDMI processor. It operates at a maximum speed of 55 MHz and features 512KB of flash and 128KB of SRAM. The 512KB of flash are split in two banks of 256KB. The peripheral set includes a USB 2.0 Full Speed device port , Ethernet MAC 10/100 port, CAN 2.0A and 2.0B compliant controller, two USART, UART, two SPI, SSC, TWI (I2C), three 16-bit timers, RTT and 8x10-bit ADC. Typical core supply is 1.8V, I/Os are supplied at 1.8V or 3.3V and are 5V tolerant. An integrated voltage regulator allows single supply at 3.3V. The SAM7X512 is supplied in 100-lead LQFP and TFBGA packages.

The ARM®-based SAM9260 running up to 210 MHz embeds Full Speed USB host and device interfaces, a 10/100 Ethernet MAC and an image sensor interface, as well as standard peripherals such as a Multimedia Card Interface (MCI), I2S, USARTs, master/slave SPIs, 16-bit Timers, a TWI and four-channel 10-bit ADC. The external bus interface features controllers for SDRAM and static memories including NAND flash and CompactFlash. The SAM9260 is available in 217-ball LFBGA and 208-pin QFP packages.

Recommended substitute device - [SAM9X60](https://www.microchip.com/en-us/product/SAM9X60) The Microchip's ARM®-based SAM9263 microprocessor runs at 240MHz and features a powerful peripheral set. User interface peripherals include a camera interface, TFT/STN LCD controller, an AC97 and I2S. Networking peripherals include USB host and device interfaces, a 10/100 Ethernet MAC and CAN. There are also four USARTs, two SPIs, CompactFlash, SD/SDIO/MMC interface and a TWI. The multi-layer bus architecture associated with 28 DMA channels, 96KB of SRAM that can be configured as TCM, and the dual bus interface, sustain the high bandwidth required by the processor and its peripherals. The SAM9263 is available in a BGA324 package with 0.8mm ball pitch.

The Microchip's ARM®-based SAM9G46 is a 400MHz ARM926-based embedded microprocessor with hardware encryption, DDR2 and LPDDR support, wide range of connectivity and user interface peripherals, and dual external bus interface. The multi-layer bus architecture associated with 35 DMA channel and 64KB of SRAM can be configured as TCM, and the dual bus interface sustains the high bandwidth required by the processor and its high-speed peripherals. The hardware encryption engine features AES 256-, 192-, 128-bit key algorithms compliant with FIPS PUB 197 Specifications, TDES two-key or three-key algorithms compliant with FIPS PUB 46-3 Specifications, a SHA Secure Hash Algorithm (SHA1 and SHA256) compliant with FIPS Publication 180-2 and a TRNG compliant with NIST SP800-22 and Diehard Random Tests suite. It integrates multiple communication interfaces such as High Speed USB host and device with transceivers, 10/100 Mbps Ethernet controller and high-speed SDIO/MMC interface. It also comes with an LCD controller supporting up to 1280x860 resolution, a resistive touchscreen controller and a camera interface. The I/Os support 3.3V. The SAM9G46 is available in a BGA324 package with 0.8mm ball pitch.
