Adesto Technologies' AT45DBxxx DataFlash devices offer uniform page erase size as small as 256 bytes. This provides the user with the ability to perform completely self-contained, read-modify-write operations with minimal system overhead and management. The devices feature a common, but extensive, command interface and an 8-pin compatible footprint for easy migration from 1 Mbit to 64 Mbit densities. The Adesto programmed unique ID number, user-programmable sector protection, permanent sector locking, page erase capability, and integrated, fully independent SRAM buffers. This enables utilization of a single, very low pin-count memory device for all nonvolatile memory needs in terms of data storage, code shadow, or combined applications.
Current 2.5 V and 2.7 V minimum voltage options, as well as 1.65 V and 2.3 V minimum versions, are in development, but DataFlash devices align well with current futureASIC and SoC technologies. The DataFlash family provides flexibility, performance, ease-of-use, and can help drive your system cost reduction initiatives.
