25B40 - EN25B40

Description

The EN25B40 is a 4M-bit (512K-byte) Serial Flash memory, with advanced write protection mechanisms, accessed by a high speed SPI-compatible bus.

The memory can be programmed 1 to 256 bytes at a time, using the Page Program instruction.

Features

  • Single power supply operation - Full voltage range: 2.7-3.6 volt.
  • 4 M-bit Serial Flash - 4 M-bit/512 K-byte/2048 pages - 256 bytes per programmable page.
  • High performance - 75MHz clock rate.
  • Low power consumption - 5 mA typical active current - 1 μA typical power down current.
  • Flexible Sector Architecture: - Two 4-Kbyte, one 8-Kbyte, one 16-Kbyte,one 32-Kbyte, and seven 64-Kbyte sectors.
  • Software and Hardware Write Protection: - Write Protec.
