MX25L1636EM2I-08G

The MX25L1636E are 16,777,216 bit serial Flash memory, which is configured as 2,097,152 x 8 internally. When it is in four I/O read mode, the structure becomes 8,388,608 bits x 2 or 4,194,304 bits x 4. The MX25L1636E 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). Serial access to the 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 input and data output. When it is in four I/O read mode, the SI pin, SO pin, WP# pin and NC pin become SIO0 pin, SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output.

The MX25L1636E provides 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 byte basis, or page (256 bytes) basis, or word basis for Continuously program mode, and erase command is executes on sector (4K-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 read command can be issued to detect completion status of a program or erase operation via WIP bit.

Secured OTP and Block Protection

When the device is not in operation and CS# is high, it is put in standby mode and draws less than 50uA DC current.
