简  介:AT45D041 Features Single 4.5V - 5.5V Supply Serial Interface Architecture Page Program Operation - Single Cycle Reprogram (Erase and Program) - 2048 Pages (264 Bytes/Page) Main Memory Two 264-Byte Data Buffers - Allows Receiving of Data while Reprogramming of Non-Volatile Memory Internal Program and Control Timer Fast Page Program Time - 7 ms Typical 80 s Typical Page to Buffer Transfer Time Low Power Dissipation - 15 mA Active Read Current Typical - 20 A CMOS Standby Current Typical 10 MHz Max Clock Frequency Hardware Data Protection Feature Serial Peripheral Interface (SPI) Compatible – Modes 0 and 3 CMOS and TTL Compatible Inputs and Outputs Commercial and Industrial Temperature Ranges 4-Megabit 5-volt Only Serial DataFlash AT45D041 Description The AT45D041 is a 5-volt only, serial interface Flash memory suitable for in-system reprogramming. Its 4,325,376 bits of memory are organized as 2048 pages of 264bytes each. In addition to the main memory, the AT45D041 also contains two data buffers of 264-bytes each. The buffers allow receiving of data while a page in the main memory is being reprogrammed. Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the DataFlash uses a serial interface to sequentially access its data. The simple serial interface facilitates hardware layout, increases system reliability, minimizes switching noise, and (continued) Pin Configurations Pin Name CS SCK SI SO WP RESET……
