AT45DB080 - 8-Megabit 2.7-volt Only Sequential Access Parallel I/O DataFlash

Download the AT45DB080 datasheet PDF. This datasheet also covers the AT4-5DB variant, as both devices belong to the same 8-megabit 2.7-volt only sequential access parallel i/o dataflash family and are provided as variant models within a single manufacturer datasheet.

General Description

The AT45DB080 is a 2.7-volt only, sequential access, parallel interface Flash memory suitable for in-system reprogramming.

Its 8,650,752 bits of memory are organized as 4096 pages of 264-bytes each.

In addition to the main memory, the AT45DB080 also contains two data buffers of 264-bytes each.

Key Features
