MX25L12845E
128M-BIT [x 1/x 2/x 4] CMOS MXSMIO® SERIAL MULTI I/O FLASH MEMORY
GENERAL DESCRIPTION
is 134,217,728 bits serial Flash memory, which is confgured as 16,777,216 x 8 internally. When it is in two or four I/O mode, the structure becomes 67,108,864 bits x 2 or 33,554,432 bits x 4. The MX25L12845E 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. Serial access to the device is enabled by CS# input.
MX25L12845E provides high performance read mode, which may latch address and data on both rising and falling edge of clock. By using this high performance read mode, the data throughput may be doubling. Moreover, the performance may reach direct code execution, the RAM size of the system may be reduced and further saving system cost.
MX25L12845E, MXSMIO Serial Multi I/O flash memory, provides sequential read operation on the whole chip and multi-I/O features.
