The MX25L6405 is a CMOS 67,108,864 bit serial
eLiteFlashTM Memory, which is configured as 8,388,608 x
8 internally. The MX25L6405 features 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 MX25L6405 provide sequential read operation on
whole chip. User may start to read from any byte of the
array. While the end of the array is reached, the device will
wrap around to the beginning of the array and continuously
outputs data until CS# goes high.
After program/erase command is issued, auto program/
erase algorithms which program/erase and verify the
specified page locations will be executed. Program com-
mand is executed on a page (256 bytes) basis, and erase
command is executed on both chip and sector (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 and error
flag status of a program or erase operation.
To increase user's factory throughputs, a parallel mode is
provided. The performance of read/program is dramatically
improved than serial mode on programmer machine.
When the device is not in operation and CS# is high, it is
put in standby mode and draws less than 50uA DC current.
The additional 4Kb sector with 100K erase/program endur-
ance cycles is suitable for parameter storage and replaces
the EEPROM on system.
The MX25L6405 utilizes MXIC's proprietary memory cell
which reliably stores memory contents even after 10K
program and erase cycles.
