Adesto Technologies Corporation, Inc. Memory AT26DF081A-SSU

The AT26DF081A-SSU is an 8-Mbit 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 Serial Peripheral Interface (SPI) modes 0 and 3, with high operating frequencies of up to 100MHz for RapidS and 85MHz for standard SPI. The device features a flexible erase architecture, allowing for block sizes of 4KB, 32KB, and 64KB, as well as full chip erase capabilities. This memory device includes individual sector protection with a global protect/unprotect feature, enabling secure management of 16 sectors of 64KB each. It also offers a sector lockdown mechanism for permanent read-only protection of selected sectors, making it suitable for secure applications. The AT26DF081A-SSU has a typical page program time of 1.0ms and supports automatic checking and reporting of erase/program failures. With an endurance of 100,000 program/erase cycles and a data retention period of 20 years, it is designed for long-term reliability. The device is available in industry-standard green packaging options, including an 8-lead SOIC and an ultra-thin DFN package. Its low power dissipation characteristics, including a typical active read current of 5mA and a deep power-down current of 5µA, make it suitable for power-sensitive applications.
