MX25L3205A
GENERAL DESCRIPTION
The MX25L3205A is a CMOS 33,554,432 bit serial
eLiteFlashTM Memory, which is configured as 4,194,304 x
8internally. TheMX25L3205Afeaturesaserialperipheral
interface and software protocol allowing operation on a
simple3-wirebus. Thethreebussignalsareaclockinput
(SCLK), a serial data input (SI), and a serial data output
(SO). SPI access to the device is enabled by CS# input.
To provide user with ease of interface, a status register is
includedtoindicatethestatusofthechip. Thestatusread
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.Theperformanceofread/programisdramatically
improved than serial mode on programmer machine.
The MX25L3205A provide sequential read operation on
whole chip. User may start to read from any byte of the
array.Whiletheendofthearrayisreached,thedevicewill
wraparoundtothebeginningofthearrayandcontinuously
outputs data until CS# goes high.
When the device is not in operation and CS# is high, it is
putinstandbymodeanddrawslessthan50uADCcurrent.

ancecyclesissuitableforparameterstorageandreplaces
the EEPROM on system.
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
commandisexecutedonbothchipandsector (64Kbytes)
basis.
TheMX25L3205AutilizesMXIC'sproprietarymemorycell
which reliably stores memory contents even after 10K
program and erase cycles.
