AS02 - 1 Mbit Memory (CAT24M01)

Overview

This xCHIP forms part of the memory modules, based on the CAT24M01 by ON Semiconductor, offering 1 Mb storage capacity for storing program configurations, data logs and other files.

The CAT24M01 is an EEPROM Serial 1-Mb I²C, internally organized as 131,072 words of 8 bits each. It features a 256-byte page write buffer and supports the Standard (100 kHz), Fast (400 kHz) and Fast-Plus (1 MHz) I²C protocol.

Up to four AS02 can be connected on in the same circuit. On-Chip ECC (Error Correction Code) makes the device suitable for high reliability applications.
