GENERAL DESCRIPTION
   The MX25L1633E are 16,777,216 bit serial Flash memory, which is configured as 2,097,152 x 8 internally. When it is in two or four I/O read mode, the structure becomes 8,388,608 bits x 2 or 4,194,304 bits x 4. The MX25L1633E 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.

FEATURES
General
