AT17N256-10NC

The Microchip model 'AT17N256-10NC' is a 256Kb Serial Configuration Memory (SCM) device that is fabricated using the high-density CMOS technology. It comes in a 32-lead TQFP package and is designed to provide a reliable and secure storage solution for system configuration files, FPGA bitstreams, and other critical data in high-end applications.

This non-volatile memory device is essentially an SPI (Serial Peripheral Interface) flash memory device that is optimized for configuration storage in FPGA (Field-Programmable Gate Array) and CPLD (Complex Programmable Logic Device) devices. It operates on a single 2.7V to 3.6V power supply and has a density of 256Kb (32Kb x 8).

Some notable features of the AT17N256-10NC include a high-speed SPI interface, serial read and write capability, and the ability to support three independent banks for storing multiple configuration files. Additionally, it has a very low standby current consumption (less than 1µA), which makes it ideal for power-sensitive applications.

The AT17N256-10NC is widely used in various high-end applications that require reliable and secure configuration storage. These applications include aerospace and defense systems, medical devices, industrial automation systems, and telecommunications equipment. Its ability to support multiple configuration banks makes it an ideal choice for applications that require field upgrades or reconfigurations, without any risk of data loss. Overall, the AT17N256-10NC offers a highly secure, reliable, and flexible storage solution for critical system configuration data.
