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 (I2C-bus). The built-in word address register is incremented...
