GENERAL DESCRIPTION
The MX25L4005 is a CMOS 4,194,304 bit serial Flash memory, which is configured as 524,288 x 8 internally. The MX25L4005 feature a serial peripheral interface and soft ware protocol allowing operation on a simple 3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). SPI access to the device is enabled by CS# input.
The MX25L4005 provide sequential read operation on whole chip.
After program/erase command is issued, auto program/erase algorithms which program/ erase and verify the specified page or byte /sector/block locations will be executed. Program command is executed on page (256 bytes) basis, and erase command is executes on chip or sector(4K-bytes) or block(64K-bytes).
To provide user with ease of interface, a status register is included to indicate the status of the chip. The status read command can be issued to detect completion status of a program or erase operation via WIP bit.
When the device is not in operation and CS# is high, it is put in standby mode and draws less than 10uA DC current.
The MX25L4005 utilize MXICs proprietary memory cell, which reliably stores memory contents even after 100,000 program and erase cycles.

FEATURES
GENERAL
• Serial Peripheral Interface (SPI) compatible -- Mode 0 and Mode 3
• 4,194,304 x 1 bit structure
• 128 Equal Sectors with 4K byte each
   - Any Sector can be erased individually
• 8 Equal Blocks with 64K byte each
   - Any Block can be erased individually
• Single Power Supply Operation
   - 2.7 to 3.6 volt for read, erase, and program operations
• Latch-up protected to 100mA from -1V to Vcc +1V
• Low Vcc write inhibit is from 1.5V to 2.5V

PERFORMANCE
• High Performance
   - Fast access time: 70MHz serial clock (15pF + 1TTL Load) and 66MHz serial clock (30pF + 1TTL Load)
   - Fast program time: 1.4ms(typ.) and 5ms(max.)/page (256-byte per page)
   - Fast erase time: 60ms(typ.) and 120ms(max.)/sector (4K-byte per sector) ; 1s(typ.) and 2s(max.)/block (64K byte per block)
• Low Power Consumption
   - Low active read current: 12mA(max.) at 70MHz, 8mA(max.) at 66MHz and 4mA(max.) at 33MHz
   - Low active programming current: 15mA (max.)
   - Low active erase current: 15mA (max.)
   - Low standby current: 10uA (max.)
   - Deep power-down mode 1uA (typical)
• Minimum 100,000 erase/program cycles

SOFTWARE FEATURES
• Input Data Format
   - 1-byte Command code
• Block Lock protection
   - The BP0~BP2 status bit defines the size of the area
      to be software protected against Program and Erase
      instructions.
• Auto Erase and Auto Program Algorithm
   - Automatically erases and verifies data at selected sector
   - Automatically programs and verifies data at selected
      page by an internal algorithm that automatically times
      the program pulse widths (Any page to be programed
      should have page in the erased state first)
• Status Register Feature
• Electronic Identification
   - JEDEC 2-byte Device ID
   - RES command, 1-byte Device ID
