AT45DB081B Descrizione generale

DescriptionThe AT45DB081B is a 2.5-volt or 2.7-volt only, serial interface Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. Its 8,650,752 bits of memory are organized as 4096 pages of 264 bytes each. In addition to the main memory, the AT45DB081B also contains two SRAM data buffers of 264 bytes each. The buffers allow receiving of data while a page in the main memory is being reprogrammed, as well as writing a continuous data stream.Features• Single 2.5V - 3.6V or 2.7V - 3.6V Supply• Serial Peripheral Interface (SPI) Compatible• 20 MHz Max Clock Frequency• Page Program Operation – Single Cycle Reprogram (Erase and Program) – 4096 Pages (264 Bytes/Page) Main Memory• Supports Page and Block Erase Operations• Two 264-byte SRAM Data Buffers – Allows Receiving of Data while Reprogramming of Nonvolatile Memory• Continuous Read Capability through Entire Array – Ideal for Code Shadowing Applications• Low Power Dissipation – 4 mA Active Read Current Typical – 2 µA CMOS Standby Current Typical• Hardware Data Protection Feature• 100% Compatible to AT45DB081 and AT45DB081A• 5.0V-tolerant Inputs: SI, SCK, CS, RESETand WPPins• Commercial and Industrial Temperature Ranges• Green (Pb/Halide-free) Packaging Options
