AT91SAM7XC512B中文资料Legacy ARM7TDMI数据手册Microchip规格书

描述 Description

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 AT91SAM7XC512 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.
