MXIC MX25U6435FM2I-10G MX25U6435F 25U6435F BIOS CHIP

MX25U6435F is 64Mb bits serial Flash memory, which is configured as 8,388,608 x 8 internally. When it is in two orfour I/O mode, the structure becomes 33,554,432 bits x 2 or 16,777,216 bits x 4. MX25U6435F feature a serial pe-ripheral interface and software protocol allowing operation on a simple 3-wire bus while it is in single I/O mode. Thethree bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). Serial access tothe device is enabled by CS# input.When it is in two I/O read mode, the SI pin and SO pin become SIO0 pin and SIO1 pin for address/dummy bits in-put and data output. When it is in four I/O read mode, the SI pin, SO pin, WP# pin and Reset# pin become SIO0pin, SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output.The MX25U6435F MXSMIO® (Serial Multi I/O) provides sequential read operation on whole chip.After program/erase command is issued, auto program/ erase algorithms which program/ erase and verify thespecified page or sector/block locations will be executed. Program command is executed on byte basis, or page (256bytes) basis, or word basis for erase command is executed on sector (4K-byte), block (32K-byte), or block (64K-byte),or whole chip basis.To provide user with ease of interface, a status register is included to indicate the status of the chip. The status readcommand can be issued to detect completion status of a program or erase operation via WIP bit.Advanced security features enhance the protection and security functions, please see security features section formore details.When the device is not in operation and CS# is high, it is put in standby mode and draws less than 30uA DC cur-rent.The MX25U6435F utilizes Macronix’s proprietary memory cell, which reliably stores memory contents even after100,000 program and erase cycles.
