GENERAL DESCRIPTION
The PCA8581 and PCA8581C are low power CMOS
EEPROMs with standard and wide operating voltages:
4.5 to 5.5 V (PCA8581)
2.5 to 6.0 V (PCA8581C).
In the following text, the generic term ‘PCA8581’ is used to
refer to both types in all packages except when otherwise
specified.
The PCA8581 is organized as 128 words of 8-bytes.
Addresses and data are transferred serially via a two-line
bidirectional bus (I
2
C-bus). The built-in word address
register is incremented automatically after each written or
read data byte. All bytes can be read in a single operation.
Up to 8 bytes can be written in one operation, reducing the
total write time per byte. Three address pins, A0, A1 and
A2 are used to define the hardware address, allowing the
use of up to 8 devices connected to the bus without
additional hardware.
