www.DataSheet4U.com IS93C46B 1,024-BIT SERIAL ELECTRICALLY ERASABLE PROM FEATURES DESCRIPTION ISSI JULY 2003 ® Industry-standard Microwire Interface The IS93C46B is a low-cost 1kb non-volatile, — Non-volatile data storage ISSI ® serial EEPROM. It is fabricated using an — Low voltage operation: enhanced CMOS design and process. The Vcc = 2.5V to 5.5V IS93C46B contains power-efficient read/write — Full TTL compatible inputs and outputs memory, and organization of 64 words of 16 bits. — Auto increment for efficient data dump The IS93C46B is fully backward compatible with x16 bit organization IS93C46. 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 x16 word can be modified with a single — Self-timed programming cycle WRITE or ERASE instruction. Additionally, the — Automatic erase-before-write two instructions WRITE ALL or ERASE ALL can — Programming status indicator program the entire array. Once a device begins — Word and chip erasable its self-timed program procedure, the data out pin DataShee — Chip select enables power savings (Dout) can indicate the R...
