AT25040B - SPI Serial EEPROM

Download the AT25040B datasheet PDF. This datasheet also covers the AT25010B variant, as both devices belong to the same spi serial eeprom family and are provided as variant models within a single manufacturer datasheet.

Description

The Atmel® AT25010B/020B/040B provides 1,024/2,048/4,096 bits of Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as 128/256/512 words of 8 bits each.

Features

  • Serial Peripheral Interface (SPI) Compatible.
  • Supports SPI Modes 0 (0,0) and 3 (1,1) ̶ Data Sheet Describes Mode 0 Operation.
  • Low-voltage and Standard-voltage Operation ̶ VCC = 1.8V to 5.5V.
  • 20MHz Clock Rate (5V).
  • 8-byte Page Mode.
  • Block Write Protection ̶ Protect 1/4, 1/2, or Entire Array.
  • Write Protect (WP) Pin and Write Disable Instructions for Both Hardware and Software Data Protection.
  • Self-timed Write Cycle (5ms max).
  • High Reliability ̶ Enduran.
