DESCRIPTION
The X84041 Micro Port Saver is a 4096-bit CMOS
E2PROM designed for a direct interface to port limited
microcontroller or I/O limited microprocessor designs.
The X84041 provides all of the benefits of serial memo-
ries, such as low cost, low power, low voltage operation,
and small package size, while featuring higher data
transfer rates and reduced interface code requirements—
without the need for a dedicated serial bus. The X84041
is organized as a 512 x 8, but is also suitable in 16-bit or
32-bit environments, due to the bit serial nature of the
interface.
The X84041 directly connects to the processor bus and
communicates over a single data line using a sequence
of standard bus read and write operations. This elimi-
nates the need for dedicated port pins, parallel to serial
converters, complicated ASIC implementations, or other
glue logic, lowering system cost.
