IS93C46-3
1,024-BIT SERIAL ELECTRICALLY
ERASABLE PROM
ISSI
OVERVIEW
The IS93C46-3 is a low cost 1,024-bit, non-volatile, serial
E
2
PROM. It is fabricated using
ISSI’s
advanced CMOS
E
2
PROM technology. The IS93C46-3 provides efficient
non-volatile read/write memory arranged as 64 registers
of 16 bits each. Seven 9-bit instructions control the
operation of the device, which includes read, write, and
mode enable functions. The data out pin (D
OUT
) indicates
the status of the device during in 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 in 16 bits
per write instruction into the selected register. If Chip
Select (CS) is brought HIGH after initiation of the write
cycle, the Data Output (D
OUT
) pin will indicate the READY/
BUSY
status of the chip.
APPLICATIONS
The IS93C46-3 is ideal for high-volume applications
requiring low power and low density storage. This device
uses a low cost, space saving 8-pin package. Candidate
applications include robotics, alarm devices, electronic
locks, meters and instrumentation settings.
