MX25L3205A

The MX25L3205A is a CMOS 33,554,432 bit serial eLiteFlashTM Memory, which is configured as 4,194,304 x 8 internally. The MX25L3205A 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 MX25L3205A 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 command is executed on a page (256 bytes) basis, and erase command is executed on both chip and sector (64K bytes) basis.

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 MX25L3205A 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 endurance cycles is suitable for parameter storage and replaces the EEPROM on system.

The MX25L3205A utilizes MXIC's proprietary memory cell which reliably stores memory contents even after 10K program and erase cycles.
