Adesto Technologies Corporation, Inc. Memory AT25DF641A-MH-T

The AT25DF641A-MH-T is a 64-Mbit SPI serial flash memory device designed for applications requiring efficient code and data storage. It operates with a supply voltage range of 2.7V to 3.6V and supports high-speed operations, achieving up to 100MHz with RapidS and 85MHz with standard SPI. The memory features a flexible erase architecture with block sizes of 4KB, 32KB, and 64KB, allowing for optimized data management and reduced memory wastage. This device includes advanced security features such as individual sector protection, global protect/unprotect capabilities, and a sector lockdown mechanism that enables specific sectors to be permanently set to read-only. It also has a One-Time Programmable (OTP) Security Register for unique device serialization and secure key storage. The AT25DF641A-MH-T is suitable for a wide range of consumer applications, providing a typical endurance of 100,000 program/erase cycles and a data retention period of 20 years. It is available in both 8-lead SOIC and ultra-thin DFN packages, compliant with RoHS standards.
