GENERAL DESCRIPTION

The MX25L1602 is a CMOS 16,777,216 bit serial Flash

EEPROM, which is configured as 2,097,152 x 8 internally.

The MX25L1602 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 MX25L1602 provide sequential read operation on

whole chip. The sequential read operation is executed on

a segment (512 byte) basis. User may start to read from

any byte of the segment. While the end of the segment is

reached, the device will wrap around to the beginning of the

segment 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 (128 bytes) basis, and

erase command is executed on both chip and sector (8K

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.

When the device is not in operation and CS is high, it is put

in standby mode and draws less than 30uA DC current.

The MX25L1602 utilizes MXIC's proprietary memory cell

which reliably stores memory contents even after 100,000

program and erase cycles.
