www.DataSheet4U.com IS93C46D 1-KBIT SERIAL ELECTRICALLY ERASABLE PROM FEATURES DESCRIPTION ISSI ADVANCED INFORMATION NOVEMBER 2005 ® Industry-standard Microwire Interface The IS93C46D is a 1Kb non-volatile, ISSI ® serial — Non-volatile data storage EEPROM. It is fabricated using an enhanced — Wide voltage operation: CMOS design and process. The IS93C46D Vcc = 1.8V to 5.5V contains power-efficient read/write memory, and — Full TTL compatible inputs and outputs organization of 128 bytes of 8 bits or 64 words of — Auto increment for efficient data dump 16 bits. When the ORG pin is connected to Vcc User Configured Memory Organization or left unconnected, x16 is selected; when it is — By 16-bit or by 8-bit connected to ground, x8 is selected. Hardware and software write protection An instruction set defines the operation of the — Defaults to write-disabled state at power-up devices, including read, write, and mode-enable — Software instructions for write-enable/disable functions. To protect against inadvertent data Enhanced low voltage CMOS E2PROM modification, all erase and write instructions are technology accepted only while the device is write-enabled. A Versatile, easy-to-use Interface selected x8 byte or x16 word can be modified with — Self-timed programming cycle a single WRITE or ERASE instruction. — Automatic erase-before-write Additionally, the two instructions WRITE ALL or — Programming status indicator ERASE ALL can program the entire array.
