IS93C76A/ Vcc = 1.8V to 5.5V -2 86A contains power-efficient read/write memory, Vcc = 2.5V to 5.5V -3 and organization of either 1,024/2,048 bytes of 8 — Full TTL compatible inputs and outputs bits or 512/1,024 words of 16 bits. When the — Auto increment for efficient data dump ORG pin is connected to Vcc or left unconnected, User Configured Memory Organization x16 is selected; when it is connected to ground, — By 16-bit or by 8-bit 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 are write-enabled. Versatile, easy-to-use Interface A selected x8 byte or x16 word can be modified — Self-timed programming cycle with a single WRITE or ERASE instruction. — Automatic erase-before-write Additionally, the two instructions WRITE ALL or DataShee — ...
