DESCRIPTION

The X84041 Micro Port Saver is a 4096-bit CMOS E2PROM designed for a direct interface to port limited microcontroller or I/O limited microprocessor designs. The X84041 provides all of the benefits of serial memories, such as low cost, low power, low voltage operation, and small package size, while featuring higher data transfer rates and reduced interface code requirements—without the need for a dedicated serial bus. The X84041 is organized as a 512 x 8, but is also suitable in 16-bit or 32-bit environments, due to the bit serial nature of the interface.
