IS93C46A-3PI中文资料矽成半导体数据手册PDF规格书

DESCRIPTION

The IS93C46A/56A/66A is a low-cost 1kb/2kb/4kb non-volatile, ISSI ® serial EEPROM. It is fabricated using an enhanced CMOS design and process. The IS93C46A/56A/66A contain power efficient read/write memory, and organziation of either 128/256/512 bytes of 8 bits or 64/128/256

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 IS93C46A/56A/66A is fully backwards compatible with IS93C46/56/66.
