AT45DB041B - 4-megabit 2.5-volt Only or 2.7-volt Only DataFlash

Download the AT45DB041B datasheet PDF. This datasheet also covers the AT4-5DB variant, as both devices belong to the same 4-megabit 2.5-volt only or 2.7-volt only dataflash family and are provided as variant models within a single manufacturer datasheet.

General Description

The AT45DB041B 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 4,325,376 bits of memory are organized as 2048 pages of 264 bytes each.

Key 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).
  • 2048 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.
