93LC56B/P vs 93LC56B-I/MS vs 93LC56-I/P Comparison

The 93LC56B/P is a 2kB MICROWIRE compatible serial Electrically Erasable Programmable Read-Only Memory (EEPROM) with word-selectable devices such as the 93AA56C, 93LC56C or 93C56C are dependent upon external logic levels driving the ORG pin to set word size. The 93LC56B device provides dedicated 16-bit communication. Advanced CMOS technology makes this device ideal for low power, nonvolatile memory applications.
