AT45D081

AT45D081 Features Single 4.5V - 5.5V Supply Serial Interface Architecture Page Program Operation – Single Cycle Reprogram (Erase and Program) – 4096 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 µs Typical Page to Buffer Transfer Time Low Power Dissipation – 15 mA Active Read Current Typical – 10 µA 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 8-Megabit 5-volt Only Serial DataFlash™ AT45D081 Description The AT45D081 is a 5-volt only, serial interface Flash memory suitable for in-system reprogramming. Its 8,650,752 bits of memory are organized as 4096 pages of 264bytes each. In addition to the main memory, the AT45D081 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 SC...
