10. 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.
10.2. Features
 Serial Peripheral Interface (SPI) compatible -- Mode 0 and Mode 3
 1,048,576 x 1 bit structure
 32 Equal Sectors with 4K byte each, Any Sector can be erased individually
 2 Equal Blocks with 64K byte each, Any Block can be erased individually
 Single Power Supply Operation
3V3 or 5V
