Description
The N24S128 is a 128 Kb Serial CMOS EEPROM, internally
organized as 816,384 words of 8 bits each.
They feature a 64-byte page write buffer and support both the
Standard (100 kHz), Fast (400 kHz) and Fast-Plus (1 MHz) I2C
protocol.
The devices also feature a 128-bit factory-set read-only Unique ID,
a 64-byte Secure Data Page that can be permanently locked against
future changes, and Software Write Protection of the entire array.
A Device Configuration Register enables the user to specify the last
3 bits of the Device Address, allowing up to eight N24S128 devices to
be addressed on the same bus.
