AT91SAM7X256B-AU ARM7® SAM7X Microcontroller IC 16/32-Bit 55MHz 256KB (256K x 8) FLASH

Description

Atmel's AT91SAM7X512/256/128 is a member of a series of highly integrated Flash microcon-trollers based on the 32-bit ARM RISC processor. It features 512/256/128 Kbyte high-speedFlash and 128/64/32 Kbyte SRAM, a large set of peripherals, including an 802.3 Ethernet MACand a CAN controller. A complete set of system functions minimizes the number of externalcomponents.The embedded Flash memory can be programmed in-system via the JTAG-ICE interface or viaa parallel interface on a production programmer prior to mounting. Built-in lock bits and a secu-rity bit protect the firmware from accidental overwrite and preserve its confidentiality.The AT91SAM7X512/256/128 system controller includes a reset controller capable of managingthe power-on sequence of the microcontroller and the complete system. Correct device opera-tion can be monitored by a built-in brownout detector and a watchdog running off an integratedRC oscillator.By combining the ARM7TDMI processor with on-chip Flash and SRAM, and a wide range ofperipheral functions, including USART, SPI, CAN Controller, Ethernet MAC, Timer Counter, RTTand Analog-to-Digital Converters on a monolithic chip, the AT91SAM7X512/256/128 is a power-ful device that provides a flexible, cost-effective solution to many embedded control applicationsrequiring communication over, for example, Ethernet, CAN wired and Zigbee™ wirelessnetworks.

Koben Electronics was founded in 1995 and is located in the Silicon Valley of China, Shenzhen. 

The mission of Koben has always been to provide quality electronics components to manufacturers worldwide. Early on we became a primary conduit for end-of-program and overstock inventory for major distributors such as Future Electronics and contract manufacturers as Flextronics. Koben has since then added sourcing of high quality components from local manufacturers in China.

Koben has always been customer driven rather than opportunity driven. Meaning- we will always choose path that is best for long term relationship with customer over short term view. It is why we have one of the highest customer retention scores of China based distributors.
