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.
An instruction set controls the operation of the
devices, including read, write, and mode-enable
functions. The data out pin (Dout) indicates the
status of the device during the self-timed non-
volatile programming cycle. The self-timed write
cycle includes an automatic erase-before-write
capability. To protect against inadvertent writes,
the WRITE instruction is accepted only while the
chip is in the write-enabled state. Data is written
once per WRITE instruction to the x8 byte or x16
word selected. If Chip Select (CS) is brought
HIGH just after initiation of the write cycle, the
Dout pin would indicate the Ready/
Busy status of
the write activity.
