NXP PCA8581CT/6,118

128 x 8-25°C ~ 85°C (TA)

Overview

The PCA8581CT/6,118 and PCA8581C are low power CMOS EEPROMs with standard and wide operating voltages:

In the following text, the generic term ‘PCA8581’ is used to refer to both types in all packages except when otherwise specified.The PCA8581CT/6,118 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 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.
