The AT91SAM7SE512 is a Flash microcontroller with external memory bus based on the 32-bit ARM7TDMI RISC processor. It 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.
Its 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. Its System Controller manages interrupts, clocks, power, time, debug and reset, significantly reducing the external chip count and minimizing power consumption.
In industrial temperature, worse case conditions the maximum clock frequency is 48MHz. Typical core supply is 1.8V, I/Os are supplied at 1.8V or 3.3V. An integrated Voltage Regulator permits single supply at 3.3V. The AT91SAM7SE512 is supplied in a 128-lead LQFP Green Package, or a 144-ball LFBGA Grren Package. It is supported by an Evaluation Board and extensive application development tools.
The AT91SAM7SE512 is a general-purpose microcontroller, particularly suited to applications requiring high performance, USB connectivity and extended on- and off-chip memory.
