Atmel AT25080/160/320/640 EEPROM Datasheet
This document describes the Atmel AT25080/160/320/640 family of Serial Electrically Erasable Programmable Read Only Memory (EEPROM) devices. These components are organized as 8K, 16K, 32K, or 64K bits and utilize a 3-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). The devices support SPI Modes 0 and 3 and operate at clock rates up to 2.1 MHz.

Questions answered in these manuals
What SPI modes are supported?
The device supports SPI Modes 0 (0,0) and 3 (1,1).
Is an erase cycle required before writing?
No, all programming cycles are completely self-timed and no separate ERASE cycle is required.
What SPI modes does the device support?
The device supports SPI Modes 0 (0,0) and 3 (1,1), though this datasheet specifically describes Mode 0 operation.
What is the typical self-timed write cycle time?
The typical self-timed write cycle time is 2 ms when operating at 5V.
How many write cycles can the EEPROM endure?
The EEPROM can endure up to one million write cycles.
What is the maximum operating voltage for the AT25080A series?
The devices operate from 2.7 V up to 5.5 V.
