AT91SAM7SE512

The AT91SAM7SE512 is a Flash microcontroller with external memory bus based on the 32-bit ARM7TDMI RISC processor. The AT91SAM7SE512 features 512K bytes of embedded high-speed Flash with sector lock capabilities and a security bit, and 32K bytes of SRAM. The integrated proprietary SAM-BA Boot Assistant enables in-system programming of the embedded Flash. The external bus interface supports SDRAM and static memories including CompactFlash and ECC-enabled NAND Flash.

The AT91SAM7SE512's extensive peripheral set includes a USB 2.0 Full Speed Device Port, USARTs, SPI, SSC, TWI and an 8-channel 10-bit ADC. Its Peripheral DMA Controller channels eliminate processor bottlenecks during peripheral-to-memory transfers. The AT91SAM7SE512's System Controller manages interrupts, clocks, power, time, debug and reset, significantly reducing the external chip count and minimizing power consumption.
