45DB081D の詳細説明
Product Overview
45DB081D is commonly associated with the Atmel AT45DB081D, an 8-Mbit DataFlash® memory designed for high-speed serial data storage in embedded systems. The device operates from a 2.5V or 2.7V-class supply and supports the RapidS™ SPI-compatible serial interface at frequencies up to 66MHz. Its memory array is organized as 4,096 pages of 256 or 264 bytes, and it also integrates two SRAM data buffers to simplify continuous data transfers and page programming. With flexible page, block, sector and chip erase operations, AT45DB081D is suitable for firmware, voice, image and general-purpose data storage applications.

Applications
45DB081D / AT45DB081D is intended for embedded products requiring flexible serial non-volatile memory with fast access and page-oriented programming. Typical applications include firmware storage, digital voice recording, image storage, industrial control equipment, instrumentation, consumer electronics, communication products and data-logging systems. :contentReference[oaicite:1]{index=1}
Quality & Sourcing
Antrex Electronics can support 45DB081D / AT45DB081D sourcing with stock availability checks, RFQ quotation, package confirmation, date code review and shipment arrangement. Because AT45DB081D is a legacy DataFlash device and was later replaced by AT45DB081E, buyers should verify the exact suffix, package, production date and compatibility requirements before procurement.
For quality control, Antrex Electronics can help arrange product photos, marking verification, visual inspection, packaging confirmation and third-party testing support when required. OEMs, EMS providers, embedded-system manufacturers and electronic component buyers are welcome to send BOM lists or obsolete Flash memory requirements for sourcing assistance.
