SPI FLASH MEMORY - MX25L1005 (U158)

10.1. General Description

MX25L1005 is a CMOS 1,048,576 bit serial Flash memory, which is configured as
131,072 x 8 internally.The MX25L1005 feature a serial peripheral interface and software
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 MX25L1005 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 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 MX25L1005 utilize MXIC's
proprietary memory cell, which reliably stores memory contents even after 100,000
program and erase cycles.
