Data appears on SI input pin when inputting data into the memory and on the SO output pin when outputting data from the memory. The devices are designed to be programmed in-system with the standard system 3.0 volt Vcc supply.

The memory can be programmed 1 to 256 bytes at a time, using the Page Program instruction. The memory supports Sector Erase and Bulk Erase instructions.

Each device requires only a 3.0 volt power supply (2.7V to 3.6V) for both read and write functions. Internally generated and regulated voltages are provided for program operations. This device does not require Vpp supply.
