DESCRIPTION

The IS93C56A/66A are 2kb/4kb non-volatile, ISSI ? serial EEPROMs. They are fabricated using an enhanced CMOS design and process. The IS93C56A/66A contain power-efficient read/write memory, and organization of either 256/512 bytes of 8 bits or 128/256 words of 16 bits. When the ORG pin is connected to Vcc or left unconnected, x16 is selected; when it is connected to ground, x8 is selected. The IS93C56A/66A are fully backward compatible with IS93C56/66.
