DESCRIPTION
The X84041 Micro Port Saver is a 4096-bit CMOS
EEPROM designed for a direct interface to port limited
microcontroller or I/O limited microprocessor designs.
The X84041 provides all of the benefits of serial mem-
ories, such as low cost, low power, low voltage opera-
tion, and small package size, while featuring higher
data transfer rates and reduced interface code require-
ments—without the need for a dedicated serial bus.
The X84041 is organized as a 512 x 8, but is also suit-
able 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 eliminates the need for dedicated port pins, paral-
lel to serial converters, complicated ASIC implementa-
tions, or other glue logic, lowering system cost.
